Setting Up A Ftp:
Well, since many of us have always wondered this, here it is. Long and drawn out. Also, before attempting this, realize one thing; You will have to give up your time, effort, bandwidth, and security to have a quality ftp server.
That being said, here it goes. First of all, find out if your IP (Internet Protocol) is static (not changing) or dynamic (changes everytime you log on). To do this, first consider the fact if you have a dial up modem. If you do, chances are about 999 999 out of 1 000 000 that your IP is dynamic. To make it static, just go to a place like h*tp://www.myftp.org/ to register for a static ip address.
You’ll then need to get your IP. This can be done by doing this:
Going to Start -> Run -> winipcfg or www.ask.com and asking ‘What is my IP?’
After doing so, you’ll need to download an FTP server client. Personally, I’d recommend G6 FTP Server, Serv-U FTPor Bullitproof v2.15 all three of which are extremely reliable, and the norm of the ftp world.
You can download them on this site: h*tp://www.liaokai.com/softw_en/d_index.htm
First, you’ll have to set up your ftp. For this guide, I will use step-by-step instructions for G6. First, you’ll have to go into ‘Setup -> General’. From here, type in your port # (default is 21). I recommend something unique, or something a bit larger (ex: 3069). If you want to, check the number of max users (this sets the amount of simultaneous maximum users on your server at once performing actions - The more on at once, the slower the connection and vice versa).
The below options are then chooseable:
-Launch with windows
-Activate FTP Server on Start-up
-Put into tray on startup
-Allow multiple instances
-Show “Loading…” status at startup
-Scan drive(s) at startup
-Confirm exit
You can do what you want with these, as they are pretty self explanatory. The scan drive feature is nice, as is the 2nd and the last option. From here, click the ‘options’ text on the left column.
To protect your server, you should check ‘login check’ and ‘password check’, ‘Show relative path (a must!)’, and any other options you feel you’ll need. After doing so, click the ‘advanced’ text in the left column. You should then leave the buffer size on the default (unless of course you know what you’re doing ), and then allow the type of ftp you want.
Uploading and downloading is usually good, but it’s up to you if you want to allow uploads and/or downloads. For the server priority, that will determine how much conventional memory will be used and how much ‘effort’ will go into making your server run smoothly.
Anti-hammering is also good, as it prevents people from slowing down your speed. From here, click ‘Log Options’ from the left column. If you would like to see and record every single command and clutter up your screen, leave the defaults.
But, if you would like to see what is going on with the lowest possible space taken, click ‘Screen’ in the top column. You should then check off ‘Log successful logins’, and all of the options in the client directry, except ‘Log directory changes’. After doing so, click ‘Ok’ in the bottom left corner.
You will then have to go into ‘Setup -> User Accounts’ (or ctrl & u). From here, you should click on the right most column, and right click. Choose ‘Add’, and choose the username(s) you would like people to have access to.
After giving a name (ex: themoonlanding), you will have to give them a set password in the bottom column (ex: wasfaked). For the ‘Home IP’ directory, (if you registered with a static server, check ‘All IP Homes’. If your IP is static by default, choose your IP from the list. You will then have to right click in the very center column, and choose ‘Add’.
From here, you will have to set the directory you want the people to have access to. After choosing the directory, I suggest you choose the options ‘Read’, ‘List’, and ‘Subdirs’, unless of course you know what you’re doing . After doing so, make an ‘upload’ folder in the directory, and choose to ‘add’ this folder seperately to the center column. Choose ‘write’, ‘append’, ‘make’, ‘list’, and ’subdirs’. This will allow them to upload only to specific folders (your upload folder).
Now click on ‘Miscellaneous’ from the left column. Choose ‘enable account’, your time-out (how long it takes for people to remain idle before you automatically kick them off), the maximum number of users for this name, the maximum number of connections allowed simultaneously for one ip address, show relative path (a must!), and any other things at the bottom you’d like to have. Now click ‘Ok’.
**Requested**
From this main menu, click the little boxing glove icon in the top corner, and right click and unchoose the hit-o-meter for both uploads and downloads (with this you can monitor IP activity). Now click the lightning bolt, and your server is now up and running.
Post your ftp info, like this:
213.10.93.141 (or something else, such as: ‘f*p://example.getmyip.com’)
User: *** (The username of the client)
Pass: *** (The password)
Port: *** (The port number you chose)
So make a FTP and join the FTP section
Listing The Contents Of A Ftp:
Listing the content of a FTP is very simple.
You will need FTP Content Maker, which can be downloaded from here:
ht*p://www.etplanet.com/download/application/FTP%20Content%20Maker%201.02.zip
1. Put in the IP of the server. Do not put “ftp://” or a “/” because it will not work if you do so.
2. Put in the port. If the port is the default number, 21, you do not have to enter it.
3. Put in the username and password in the appropriate fields. If the login is anonymous, you do not have to enter it.
4. If you want to list a specific directory of the FTP, place it in the directory field. Otherwise, do not enter anything in the directory field.
5. Click “Take the List!”
6. After the list has been taken, click the UBB output tab, and copy and paste to wherever you want it.
If FTP Content Maker is not working, it is probably because the server does not utilize Serv-U Software.
If you get this error message:
StatusCode = 550
LastResponse was : ‘Unable to open local file test-ftp’
Error = 550 (Unable to open local file test-ftp)
Error = Unable to open local file test-ftp = 550
Close and restart FTP Content Maker, then try again.
error messages:
110 Restart marker reply. In this case, the text is exact and not left to the particular implementation; it must read: MARK yyyy = mmmm Where yyyy is User-process data stream marker, and mmmm server’s equivalent marker (note the spaces between markers and “=”).
120 Service ready in nnn minutes.
125 Data connection already open; transfer starting.
150 File status okay; about to open data connection.

Active FTP vs. Passive FTP, a Definitive Explanation
Introduction
One of the most commonly seen questions when dealing with firewalls and other Internet connectivity issues is the difference between active and passive FTP and how best to support either or both of them. Hopefully the following text will help to clear up some of the confusion over how to support FTP in a firewalled environment.
This may not be the definitive explanation, as the title claims, however, I’ve heard enough good feedback and seen this document linked in enough places to know that quite a few people have found it to be useful. I am always looking for ways to improve things though, and if you find something that is not quite clear or needs more explanation, please let me know! Recent additions to this document include the examples of both active and passive command line FTP sessions. These session examples should help make things a bit clearer. They also provide a nice picture into what goes on behind the scenes during an FTP session. Now, on to the information…
The Basics
FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a ‘data’ port and a ‘command’ port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port. The confusion begins however, when we find that depending on the mode, the data port is not always on port 20.
Active FTP
In active mode FTP the client connects from a random unprivileged port (N > 1024) to the FTP server’s command port, port 21. Then, the client starts listening to port N+1 and sends the FTP command PORT N+1 to the FTP server. The server will then connect back to the client’s specified data port from its local data port, which is port 20.
From the server-side firewall’s standpoint, to support active mode FTP the following communication channels need to be opened:
FTP server’s port 21 from anywhere (Client initiates connection)
FTP server’s port 21 to ports > 1024 (Server responds to client’s control port)
FTP server’s port 20 to ports > 1024 (Server initiates data connection to client’s data port)
FTP server’s port 20 from ports > 1024 (Client sends ACKs to server’s data port)
In step 1, the client’s command port contacts the server’s command port and sends the command PORT 1027. The server then sends an ACK back to the client’s command port in step 2. In step 3 the server initiates a connection on its local data port to the data port the client specified earlier. Finally, the client sends an ACK back as shown in step 4.
The main problem with active mode FTP actually falls on the client side. The FTP client doesn’t make the actual connection to the data port of the server–it simply tells the server what port it is listening on and the server connects back to the specified port on the client. From the client side firewall this appears to be an outside system initiating a connection to an internal client–something that is usually blocked.
Active FTP Example
Below is an actual example of an active FTP session. The only things that have been changed are the server names, IP addresses, and user names. In this example an FTP session is initiated from testbox1.slacksite.com (192.168.150.80), a linux box running the standard FTP command line client, to testbox2.slacksite.com (192.168.150.90), a linux box running ProFTPd 1.2.2RC2. The debugging (-d) flag is used with the FTP client to show what is going on behind the scenes. Everything in red is the debugging output which shows the actual FTP commands being sent to the server and the responses generated from those commands. Normal server output is shown in black, and user input is in bold.
There are a few interesting things to consider about this dialog. Notice that when the PORT command is issued, it specifies a port on the client (192.168.150.80) system, rather than the server. We will see the opposite behavior when we use passive FTP. While we are on the subject, a quick note about the format of the PORT command. As you can see in the example below it is formatted as a series of six numbers separated by commas. The first four octets are the IP address while the second two octets comprise the port that will be used for the data connection. To find the actual port multiply the fifth octet by 256 and then add the sixth octet to the total. Thus in the example below the port number is ( (14*256) + 178), or 3762. A quick check with netstat should confirm this information.

Passive FTP
In order to resolve the issue of the server initiating the connection to the client a different method for FTP connections was developed. This was known as passive mode, or PASV, after the command used by the client to tell the server it is in passive mode.
In passive mode FTP the client initiates both connections to the server, solving the problem of firewalls filtering the incoming data port connection to the client from the server. When opening an FTP connection, the client opens two random unprivileged ports locally (N > 1024 and N+1). The first port contacts the server on port 21, but instead of then issuing a PORT command and allowing the server to connect back to its data port, the client will issue the PASV command. The result of this is that the server then opens a random unprivileged port (P > 1024) and sends the PORT P command back to the client. The client then initiates the connection from port N+1 to port P on the server to transfer data.
From the server-side firewall’s standpoint, to support passive mode FTP the following communication channels need to be opened:
FTP server’s port 21 from anywhere (Client initiates connection)
FTP server’s port 21 to ports > 1024 (Server responds to client’s control port)
FTP server’s ports > 1024 from anywhere (Client initiates data connection to random port specified by server)
FTP server’s ports > 1024 to remote ports > 1024 (Server sends ACKs (and data) to client’s data port)
In step 1, the client contacts the server on the command port and issues the PASV command. The server then replies in step 2 with PORT 2024, telling the client which port it is listening to for the data connection. In step 3 the client then initiates the data connection from its data port to the specified server data port. Finally, the server sends back an ACK in step 4 to the client’s data port.
While passive mode FTP solves many of the problems from the client side, it opens up a whole range of problems on the server side. The biggest issue is the need to allow any remote connection to high numbered ports on the server. Fortunately, many FTP daemons, including the popular WU-FTPD allow the administrator to specify a range of ports which the FTP server will use. See Appendix 1 for more information.
The second issue involves supporting and troubleshooting clients which do (or do not) support passive mode. As an example, the command line FTP utility provided with Solaris does not support passive mode, necessitating a third-party FTP client, such as ncftp.
With the massive popularity of the World Wide Web, many people prefer to use their web browser as an FTP client. Most browsers only support passive mode when accessing ftp:// URLs. This can either be good or bad depending on what the servers and firewalls are configured to support.
Passive FTP Example
Below is an actual example of a passive FTP session. The only things that have been changed are the server names, IP addresses, and user names. In this example an FTP session is initiated from testbox1.slacksite.com (192.168.150.80), a linux box running the standard FTP command line client, to testbox2.slacksite.com (192.168.150.90), a linux box running ProFTPd 1.2.2RC2. The debugging (-d) flag is used with the FTP client to show what is going on behind the scenes. Everything in red is the debugging output which shows the actual FTP commands being sent to the server and the responses generated from those commands. Normal server output is shown in black, and user input is in bold.
Notice the difference in the PORT command in this example as opposed to the active FTP example. Here, we see a port being opened on the server (192.168.150.90) system, rather than the client. See the discussion about the format of the PORT command above, in the Active FTP Example section.

Summary
The following chart should help admins remember how each FTP mode works:
Active FTP :
command : client >1024 -> server 21
data : client >1024 <- server 20
Passive FTP :
command : client >1024 -> server 21
data : client >1024 -> server >1024
A quick summary of the pros and cons of active vs. passive FTP is also in order:
Active FTP is beneficial to the FTP server admin, but detrimental to the client side admin. The FTP server attempts to make connections to random high ports on the client, which would almost certainly be blocked by a firewall on the client side. Passive FTP is beneficial to the client, but detrimental to the FTP server admin. The client will make both connections to the server, but one of them will be to a random high port, which would almost certainly be blocked by a firewall on the server side.
Luckily, there is somewhat of a compromise. Since admins running FTP servers will need to make their servers accessible to the greatest number of clients, they will almost certainly need to support passive FTP. The exposure of high level ports on the server can be minimized by specifying a limited port range for the FTP server to use. Thus, everything except for this range of ports can be firewalled on the server side. While this doesn’t eliminate all risk to the server, it decreases it tremendously.
1. Click on “Start” in the bottom left hand corner of screen
2. Click on “Run”
3. Type in “command” and hit ok
You should now be at an MSDOS prompt screen.
4. Type “ipconfig /release” just like that, and hit “enter”
5. Type “exit” and leave the prompt
6. Right-click on “Network Places” or “My Network Places” on your desktop.
7. Click on “properties”
You should now be on a screen with something titled “Local Area Connection”, or something close to that, and, if you have a network hooked up, all of your other networks.
8. Right click on “Local Area Connection” and click “properties”
9. Double-click on the “Internet Protocol (TCP/IP)” from the list under the “General” tab
10. Click on “Use the following IP address” under the “General” tab
11. Create an IP address (It doesn’t matter what it is. I just type 1 and 2 until i fill the area up).
12. Press “Tab” and it should automatically fill in the “Subnet Mask” section with default numbers.
13. Hit the “Ok” button here
14. Hit the “Ok” button again
You should now be back to the “Local Area Connection” screen.
15. Right-click back on “Local Area Connection” and go to properties again.
16. Go back to the “TCP/IP” settings
17. This time, select “Obtain an IP address automatically”
tongue.gif 18. Hit “Ok”
19. Hit “Ok” again
20. You now have a new IP address
With a little practice, you can easily get this process down to 15 seconds.
P.S:
This only changes your dynamic IP address, not your ISP/IP address. If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back

Repair broken IE July 22, 2008
Posted by mahendragr in internet.
add a comment
So one of your friends, “not you of course”, has managed to nuke Internet Explorer and they are unsure how they did it. You’ve eliminated the possibility of viruses and adware, so this just leaves you and a broken IE. Before you begin to even consider running a repair install of the OS, let’s try to do a repair on IE instead.
THE REPAIR PROCESS
Start the Registry Editor by typing regedit from the Run box. Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Active Setup \ Installed Components \ {89820200-ECBD-11cf-8B85-00AA005B4383} and then right-click the “IsInstalled value.” Click Modify. From there, you will change the value from 1 to 0. All right, go ahead and close the editor and reinstall IE from this location. /http://www.microsoft.com/windows/ie/default.mspx
IF SOMETHING GOES WRONG
If messing with the registry and something goes horribly wrong, you can use “Last Known Good Configuration (F8 Safe Mode)” or a Restore Point to get back to where you were before, with your settings. Then you can try again, this time taking care to watch the portion of the registry you are changing. Most people who have troubles with this end up changing the wrong registry key.
Hope this tut helps some members.
Tracking email back to its source: Twisted Evil
cause i hate spammers… Evil or Very Mad
Ask most people how they determine who sent them an email message and the response is almost universally, “By the From line.” Unfortunately this symptomatic of the current confusion among internet users as to where particular messages come from and who is spreading spam and viruses. The “From” header is little more than a courtesy to the person receiving the message. People spreading spam and viruses are rarely courteous. In short, if there is any question about where a particular email message came from the safe bet is to assume the “From” header is forged.
So how do you determine where a message actually came from? You have to understand how email messages are put together in order to backtrack an email message. SMTP is a text based protocol for transferring messages across the internet. A series of headers are placed in front of the data portion of the message. By examining the headers you can usually backtrack a message to the source network, sometimes the source host. A more detailed essay on reading email headers can be found .
If you are using Outlook or Outlook Express you can view the headers by right clicking on the message and selecting properties or options.
Below are listed the headers of an actual spam message I received. I’ve changed my email address and the name of my server for obvious reasons. I’ve also double spaced the headers to make them more readable.

According to the From header this message is from Maricela Paulson at s359dyxxt@yahoo.com. I could just fire off a message to abuse@yahoo.com, but that would be waste of time. This message didn’t come from yahoo’s email service.
The header most likely to be useful in determining the actual source of an email message is the Received header. According to the top-most Received header this message was received from the host 12-218-172-108.client.mchsi.com with the ip address of 21.218.172.108 by my server mailhost.example.com. An important item to consider is at what point in the chain does the email system become untrusted? I consider anything beyond my own email server to be an unreliable source of information. Because this header was generated by my email server it is reasonable for me to accept it at face value.
The next Received header (which is chronologically the first) shows the remote email server accepting the message from the host 0udjou with the ip 193.12.169.0. Those of you who know anything about IP will realize that that is not a valid host IP address. In addition, any hostname that ends in client.mchsi.com is unlikely to be an authorized email server. This has every sign of being a cracked client system.
Here’s is where we start digging. By default Windows is somewhat lacking in network diagnostic tools; however, you can use the tools at to do your own checking.

Address: 127.0.0.1
Name: 12-218-172-108.client.mchsi.com
Address: 12.218.172.108
Ok, whois shows that Mediacom Communications owns that netblock and nslookup confirms the address to hostname mapping of the remote server,12-218-172-108.client.mchsi.com. If I preface a www in front of the domain name portion and plug that into my web browser, http://www.mchsi.com, I get Mediacom’s web site.
There are few things more embarrassing to me than firing off an angry message to someone who is supposedly responsible for a problem, and being wrong. By double checking who owns the remote host’s IP address using two different tools (whois and nslookup) I minimize the chance of making myself look like an idiot.
A quick glance at the web site and it appears they are an ISP. Now if I copy the entire message including the headers into a new email message and send it to abuse@mchsi.com with a short message explaining the situation, they may do something about it.
But what about Maricela Paulson? There really is no way to determine who sent a message, the best you can hope for is to find out what host sent it. Even in the case of a PGP signed messages there is no guarantee that one particular person actually pressed the send button. Obviously determining who the actual sender of an email message is much more involved than reading the From header. Hopefully this example may be of some use to other forum regulars.
Steps:
1] Browse C:\WINDOWS\system32\drivers\etc
2] Find the file named “HOSTS”
3] Open it in notepad
4] Under “127.0.0.1 localhost” Add 127.0.0.2 www.sitenameyouwantblocked.com , and that site will no longer be accessable.
5] Done!
-So-
127.0.0.1 localhost
127.0.0.2 www.blockedsite.com
–>www.blockedsite.com is now unaccessable<–
For every site after that you want to add, just add “1″ to the last number in the internal ip (127.0.0.2) and then the addy like before.
IE: 127.0.0.3 www.blablabla.com
127.0.0.4 www.blablabla.com
127.0.0.5 www.blablabla.com
etc
Configuring your Bulletproof FTP Server Tutorial
I am not sure where I found this tutorial, It’s been a while…..So if it is one of yours, my hat goes off to you once again….
I thought that perhaps this tutorial might be pretty helpful for those interested in knowing how to configure their Bulletproof FTP Server that don’t already know how… Here’s how to get started…
This is for the BulletProof FTP Server 2.10. However, It should work fine on most following versions as well.
I’m assuming you have it installed and cracked.
Basics
1. Start the program.
2. Click on Setup > Main > General from the pull-down menu.
3. Enter your server name into the ‘Server Name’ box. Under Connection set the “Max number of users” to any number. This is the limit as to how many users can be on your sever at any time.
4. Click on the ‘options’ tab of that same panel (on the side)
5. Look at the bottom, under IP Options. Put a check in the box “Refuse Multiple Connections from the same IP”. This will prevent one person from blocking your FTP to others.
6. Also put a check in the ‘Blocked Banned IP (instead of notifying client). VERY IMPORTANT! If somebody decides to ‘Hammer’ (attempt to login numerous times VERY quickly) your server/computer may CRASH if you don’t enable this.
7. Click on the ‘advanced’ tab
8. At the bottom again look at the ‘hammering area’
9. Enable ‘anti-hammer’ and ‘do not reply to people hammering’ Set it for the following: Block IP 120 min if 5 connections in 60 sec. You can set this at whatever you want to but that is pretty much a standard Click ‘OK’
Adding Users
11. Setup > User accounts form pull-down.
12. Right click in the empty ‘User Accounts’ area on the right: choose ‘Add’
13. Enter account name. (ie: logon name)
14. In the ‘Access rights’ box right click: choose ‘Add’.
15. Browse until you find the directory (folder) you want to share. In the right column you will see a bunch of checkboxes. Put a check in the following ones: Read, Write, Append, Make, List, and +Subdirs. Press ’select’.
16. Enter a password for your new FTP account.
17. Click on ‘Miscellaneous’ in the left column. Make sure ‘Enable Account’ is selected. Enable ‘Max Number of Users’ set it at a number other than zero. 1 for a personal account and more that one for a group account. Enable ‘Max. no. of connects per IP’ set it at 1
18. Under ‘Files’ enable ’show relative path’ this is a security issue. A FTP client will now not be able to see the ENTIRE path of the FTP. It will only see the path from the main directory. Hide hidden flies as well.
Put a tick in both of these.
Advanced:
You don’t need to do any of this stuff, but It will help tweak your server and help you maintain order on it. All of the following will be broken down into small little areas that will tell you how to do one thing at a time.
Changing the Port
The default port is always 21, but you can change this. Many ISPs will routinely do a scan of its own users to find a ftp server, also when people scan for pubs they may scan your IP, thus finding your ftp server. If you do decide to change it many suggest that you make the port over 10,000.
1. Setup > Main > General
2. In the ‘Connection’ Area is a setting labeled ‘Listen on Port Number:’
3. Make it any number you want. That will be your port number.
4. Click ‘OK’
Making an ‘Upload Only’ or ‘Download Only’ ftp server.
This is for the entire SERVER, not just a user.
1. Setup > Main > Advanced
2. In the advanced window you will have the following options: uploads and downloads, downloads only, and uploads only. By default upload and download will be checked. Change it to whatever you want.
3. Click ‘OK’
While you are running your server, usually you will end up spending more time at your computer than you normally do. Don’t be afraid to ban IP’s. Remember, on your FTP you do as you want.
When you are online you must also select the open server button next to the on-line button which is the on-line Button
You also have to use the actual Numbered ip Address ie: 66.250.216.67
Or even Better yet, get a no-ip.com address
So one of your friends, “not you of course”, has managed to nuke Internet Explorer and they are unsure how they did it. You’ve eliminated the possibility of viruses and adware, so this just leaves you and a broken IE. Before you begin to even consider running a repair install of the OS, let’s try to do a repair on IE instead.
THE REPAIR PROCESS
Start the Registry Editor by typing regedit from the Run box. Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Active Setup \ Installed Components \ {89820200-ECBD-11cf-8B85-00AA005B4383} and then right-click the “IsInstalled value.” Click Modify. From there, you will change the value from 1 to 0. All right, go ahead and close the editor and reinstall IE from this location. /http://www.microsoft.com/windows/ie/default.mspx
IF SOMETHING GOES WRONG
If messing with the registry and something goes horribly wrong, you can use “Last Known Good Configuration (F8 Safe Mode)” or a Restore Point to get back to where you were before, with your settings. Then you can try again, this time taking care to watch the portion of the registry you are changing. Most people who have troubles with this end up changing the wrong registry key.
Hope this tut helps some members.

HOW TO STOP SPAM VIA WINDOWS MESSENGER SERVICE
Below you’ll find many ways (sorted in the most successful ratio first) to
stop the Windows Messenger service, depending on your system
environment, some may require more than one process. This service is
available only on NT, 2K, XP & Server 2003. Administrator Login is
REQUIRED
About The Messenger Service
* Messenger is a Windows Service that runs in the background
* Messenger is not the same as MSN Messenger or any other Instant
Messaging Program
* Messenger does not facilitate two-way chatting
* Many Windows Programs, Firewalls, UPS and Antiviruses require the
Messenger Service
* Antivirus and UPS software, among others, may not work if Messenger is
disabled
* The Messenger Service is usually turned on by default in most Windows
NT, 2K and XP systems
1. Manually
1. Example 1
1. Click Start, Run and enter the following command:
RunDll32 advpack.dll,LaunchINFSection
%windir%\inf\msmsgs.inf,BLC.Remove
NOTE: This will prevent a long delay when opening Outlook Express if you
have the Contacts pane enabled
2. To prevent this, click Start, Run and enter {REGEDIT} Go to:
HKEY_LOCAL_MACHINE\Software\Mcft\Outlook Express
3. Right click in the right pane and select New, Dword value
4. Give it the name Hide Messenger Double click this new entry and set the
value to 2
5. End result should look EXACTLY like this:
System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Mcft\Outlook
Express]
Value Name: Hide Messenger
Data Type: REG_DWORD (DWORD Value)
Value Data: (2 = remove messenger)
2. Example 2
1. Copy and paste the following to Run Command Bar in the Start Menu:
RunDll32.exe advpack.dll,LaunchINFSection
%windir%\inf\msmsgs.inf,BLC.Remove
3. Example 3
1. If Example 5 didn’t work, then try this - Many users miss or don’t know of
it
2. Click on Start then go to RUN and type:
C:\WINDOWS\inf\sysoc.inf
3. Change:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
4. To:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,7
5. Then use Add/Remove Windows Components to remove Messenger
NOTE: You can also prevent access to Windows Messenger using Group
Policy or the Set Program Access and Defaults utility added by default in
Windows XP SP1 and Windows 2000 SP3
4. Example 4
1. Open Windows Messenger
2. From the menu, select “Tools” then “Options” then “Preferences” tab
3. Uncheck “Run this program when Windows starts”
4. Open Outlook Express
5. From the menu, select “Tools” then “Options” then “General” tab
6. Uncheck the option to “Automatically log on”, if it’s there
7. Also in Outlook Express, select “View” then “Layout”
8. Uncheck the option to “display Contacts” - The program will open a
connection and display a list of all Contacts on line if you do not
9. In “Startup Folder” make sure there is no entry there for Messenger
10. Open Norton Anti-Virus if you have it installed
11. Click “Options” then “Instant Messenger”
12. Unckeck “Windows Messenger (recommended”
NOTE: This list ought to work in disassociate MSN from Outlook Express,
so that it’ll only start up if you really want it to
5. Example 5
1. 2000
* Click Start-> Settings-> Control Panel-> Administrative Tools->Services
* Scroll down and highlight “Messenger”
* Right-click the highlighted line and choose Properties
* Click the STOP button
* Select Disable in the Startup Type scroll bar
* Click OK
2. XP Home
* Click Start->Settings ->Control Panel
* Click Performance and Maintenance
* Click Administrative Tools
* Double click Services
* Scroll down and highlight “Messenger”
* Right-click the highlighted line and choose Properties
* Click the STOP button
* Select Disable in the Startup Type scroll bar
* Click OK
3. XP Professional
* Click Start->Settings ->Control Panel
* Click Administrative Tools
* Click Services
* Double click Services
* Scroll down and highlight “Messenger”
* Right-click the highlighted line and choose Properties.
* Click the STOP button.
* Select Disable in the Startup Type scroll bar
* Click OK
4. Windows NT
* Click Start ->Control Panel
* Double Click Administrative Tools
* Select Services-> Double-click on Messenger
* In the Messenger Properties window, select Stop
* Then choose Disable as the Startup Type
* Click OK
NOTE: If you stop the service and don’t adjust the startup type, the
Messenger service will start automatically the next time you reboot. Keep in
mind that when you disable the Messenger service, you’ll no longer receive
messages about an attached UPS, and you won’t be notified of print job
completion, performance alerts, or antivirus activity (from Windows) not the
program you’re using for those purposes.
6. Example 6
1. To disable receipt of messenger pop-ups, verify that your firewall
disables inbound traffic on UDP ports 135, 137, and 138, and TCP ports
135 and 139. On a system connected directly to the Internet, you should
also disable inbound traffic on TCP port 445. If the system you want to
protect is part of a Win2K-based network with Active Directory (AD), don’t
block incoming traffic on port 445 - Mcft Knowledge Base Article - 330904
Code:
http://support.Mcft.com/default.aspx?scid=kb;en-us;330904
NOTE: You can use the firewall approach only if your system doesn’t
communicate with legacy systems that rely on NetBIOS name resolution to
locate machines and shared resources. If, for example, you let users
running Windows 9x share your printer or scanner, when you disable
inbound NetBIOS traffic, users won’t be able to connect to these shared
resources. Regardless of the method you choose, you can stop messenger
spam
2. Program
1. Example 1
NOTE: On Oct 15, 2003, Mcft releases Critical Security Bulletin MS03-043
warning users that the Windows Messenger Service running and exposed
by default in all versions of Windows NT, 2000 and XP, contains a “Remote
Code Execution” vulnerability that allows any not otherwise secured and
protected Windows machine to be taken over and remotely compromised
over the Internet
1. Shoot the Messenger
Code:
http://grc.com/files/shootthemessenger.exe
2. Example 2
1. Messenger Disable
Code:
http://www.dougknox.com/xp/utils/MessengerDisable.zip
NOTE: If you choose to uninstall Windows Messenger on a system with
SP1 installed, you will receive an error message about “un-registering” an
OCX file. This is normal, and doest not affect the removal process.
Windows Messenger will still be removed
3. TEST
1. Example 1
1. Right-click “My Computer”
2. Select “Manage”
3. Under “System Tools” right-click on “Shared Folders”
4. Choose “All Tasks” and select “Send Console Message…”
5. If you recieve the following error message then the service has been
disabled, otherwise confirm that you have disabled it or try another example
“The following error occured while reading the list of sessions from
Windows clients:
Error 2114: The Server service is not started.”
2. Example 2
1. Click Start then “Run”
2. Type in {cmd.exe}
3. Type in net send 127.0.0.1 hi
4. If you get a popup “hi” message, then confirm that you have disabled it
or try another example
4. IF YOU INSIST
1. If you insist on keeping Windows Messenger, then I’d recommend
Messenger Manager - “Allows you to keep your messenger service
running, as is intended and needed by Windows. This ensures that vital
system errors and notifications may be sent informing you of Important
System Events”
Code:
http://www.sellertools.com/default.asp?i=MessageManager3.htm
2. However, as a replacement to Windows Messenger remote control
feature, I’d recommend this free tool Virtual Network Computing - “It is a
remote control software which allows you to view and interact with one
computer (the “server”) using a simple program (the “viewer”) on another
computer anywhere on the Internet. The two computers don’t even have to
be the same type, so for example you can use VNC to view an office Linux
machine on your Windows PC at home”

RESULTS WILL VARY
No matter how good your systems may be, they’re only as effective as what
you put into them.
This tutorial is meant for the person who would like to set up there own little
web server. It’s not meant for the IT Person running a fortune 500 company. But hey if you want go ahead.
Instalation:
First thing you need is to download the webserver. Now for windows
users your gonna want to go download the .exe . The apache website is www.apache.org Your gonna wanna head to the apache
binaries sections for Win32 I believe it is at http://www.apache.org/dist/httpd/binaries/win32/
There you will be able to download a version of apache.
Now before you download it you gonna want to make a folder. This folder is
where your gonna server your root directory. Now if you don’t want to do
this it’s ok. You can use the default path if you want. Put usually this helps
in setting up other things like php, and MySQL. Most people do is they create
a folder in the C:\ directory called WWW or somthin. You can name it whatever you want.
Ok so have downloaded the Apache Web Server. Your ready to go with the setup.
No the version I have downloaded was apache_2.0.36-win32-x86-no_ssl.msi This
was a newer version and supposedly supposed to be more secure. The first screen you get when your in the setup is The welcome screen we don’t care much about that
but owell so hit next. The next screen is the terms and service. And yes
your going to agree to the terms duh. The next screen is some documentation.
I never really read it but if you want go ahead and do it. Once your done
hit next again. Know we see a screen that says enter a network domain. Erase what is ever in there and type localhost. Now the next box says
Servername, erace what is ever in the box and put in localhost.
The next is Administrators e-mail address. Go ahead and fill that in.
But make sure to change it. Now there are 2 little radio buttons.
Pick the one that best suites your needs. Now that we got that all
filled out. Hit Next and you’ll go to a screen that asks you which
type of install you want to do. Then hit next.
If you wanted to server out of your one special folder. Change the
file location of were your gonna install apache. Or just leave it at the default path. Click install and it should be on
it’s way. Once it’s done installing hit the finish button.
The test:
First were gonna check to see if Apache installed correctly.
This is how we do it. Open up Internet Explorer and type in ” http://localhost” . If everything went smooth then you should
be seeing a message that looks like this” Seeing this instead of the website you expected?” Yippee!!!
Apache is working. See now wasnt’ that really simple. Ok now were gonna
do some fun stuff.
Alright now that we got or test done lets move on to changing some of this
stuff that apache did on default. In Internet Explorer if you installed
on the deafult path. Make your way to C:\Program Files\Apache Group\Apache2
This is your Main Apache Directory were you can find everything. If you want
take a short break and run around. There are some cool things there. Don’t
worry if you don’t understand what’s in these files just yet.
Break Time:
Go take a leak, get some pepsi and somthin to eat. If you got smokes light
them up in your new found glory.
Alright so now you’ve got apache installed and your about to start dishing out
your web pages that you took so much time on to build. Head to the folder called
htdocs, this is your main folder. There should be a whole bunch of pages What i do
is i select them all and move them to another folder. The htdocs folder is the best
folder in the world. It’s gonna be one of the places you spend most of your time
dishing out content for the world. Ok so get rid of all that stuff that is in your
htdocs folder. And move all your great content inside replacing it. Alright so now
once we moved all are content inside the htdocs folder and we tested it to make
sure it was there. http://localhost remember. Now let’s get out of there. Go to
Apache’s main directory. Now just to be aware of what is going on and get a good
example of how Apache Functions head off to a folder called “conf” This is the
configuration files Apache Uses. If you ever wanted to install php and other
server side scripting languages this is where you would do it. Now you get 2 copys
Use 1 as a backup and never edit it at all. Go ahead and open the folder and open
“httpd.conf” Read it very carefully cause in this tutorial were not gonna read
about it. I just want you to know it’s there. Anytime you edit the httpd.conf file
you must re-start apache in order for it to work. Another good tip for you new people
to apache is you may notice the log files. Yes there great and make sure to make backups
of the logs they will come in handy. As security precautions. I also recommend getting
a firewall set up. There are lots of great security features that apache has but this
is a tutorial to installing apache.
Alright so now you’ve got your webpages up. But the only way people will be able to view
your pages is my typing in your ip address. This is a bumper. Lets look at some free
re-directories. www.n2v.net, This is a cool one. You sign up put your ip adress of your
new webserver in and whalla your done. Type in www. .n2v.net and it goes to your server
and brings up your super nice webpages. Now if you go to google and search for free
domain names or re-directors you should come up with alot. Many People already know
about the www.dot.tk one of the coolest things in the world. Free .tk very simple
That’s all you need. It works perfect for my webserver and I’ve got around 3,000 hits
so it’s working good. If you don’t wanna do it you don’t have to. But it just
makes it simple.
Alright that comes to the conclusion of installing Apache Win32 for WINDOWS users.
Very easy. One last thing Please Read more of the Apache
Documentation either on there website or in your Apache2
directory. If you liked reading this tutorial on how to setup Apache check my
website for others at www.bonfire.tk . Yes there will be follow ups. I’ll be
writing another apache tutorail soon so you can set up PHP. The most awesome
scripting language ever built. And also another on how to secure Apache and yes
ALL FOR WINDOWS!! .

Yes, firefox is already pretty damn fast but did you know that you can tweak it and improve the speed even more?
That’s the beauty of this program being open source.
Here’s what you do:
In the URL bar, type “about:config” and press enter. This will bring up the configuration “menu” where you can change the parameters of Firefox.
Note that these are what I’ve found to REALLY speed up my Firefox significantly - and these settings seem to be common among everybody else as well. But these settings are optimized for broadband connections - I mean with as much concurrent requests we’re going to open up with pipelining… lol… you’d better have a big connection.
Double Click on the following settins and put in the numbers below - for the true / false booleans - they’ll change when you double click.
Code:
browser.tabs.showSingleWindowModePrefs – true
network.http.max-connections – 48
network.http.max-connections-per-server – 16
network.http.max-persistent-connections-per-proxy – 8
network.http.max-persistent-connections-per-server – 4
network.http.pipelining – true
network.http.pipelining.maxrequests – 100
network.http.proxy.pipelining – true
network.http.request.timeout – 300
One more thing… Right-click somewhere on that screen and add a NEW -> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0”. This value is the amount of time the browser waits before it acts on information it receives. Since you’re broadband - it shouldn’t have to wait.
Now you should notice you’re loading pages MUCH faster now!
These settings allow you to boost the speed of your broadband Internet connection when using a Cable Modem or DSL Router with Windows 2000 and Windows XP.
Open your registry and find the key below.
Create the following DWORD values, as most of these values will not already exist you will need to create them by clicking on ‘Edit -> New -> DWORD Value’ and then set the value as shown below.
DefaultTTL = “80″ hex (or 128 decimal)
Specifies the default time to live (TTL) for TCP/IP packets. The default is 32.
EnablePMTUBHDetect = “0″
Specifies whether the stack will attempt to detect Maximum Transmission Unit (MTU) routers that do not send back ICMP fragmentation-needed messages. The default is 0.
EnablePMTUDiscovery = “1″
Specifies whether the TCP/IP stack will attempt to perform path MTU discovery as specified in RFC 1191. The default is 1.
GlobalMaxTcpWindowSize = “7FFF” hex (or 32767 decimal)
Specifies the system maximum receive window size advertised by the TCP/IP stack.
TcpMaxDupAcks = “2″
Determines the number of duplicate ACKs that must be received for the same sequence number of sent data before “fast retransmit” is triggered.
SackOpts = “1″
Enables support for selective acknowledgements as documented by Request for Comment (RFC) 2018. Default is 0.
Tcp1323Opts = “1″
Controls RFC 1323 time stamps and window scaling options. Possible values are: “0″ = disable RFC 1323 options, “1″ = window scale enabled only, “2″ = time stamps enabled only and “3″ = both options enabled.
TcpWindowSize = “7FFF” hex (or 32767 decimal)
Specifies the receive window size advertised by the TCP/IP stack. If you have a latent network you can try increasing the value to 93440, 186880, or 372300.
Exit your registry and restart Windows for the changes to take effect.
If you don’t want to edit the registry, here’s a little TCP utility that is ideal…
A nice little tweak for XP. Microsoft reserve 20% of your available bandwidth for their own purposes (suspect for updates and interrogating your machine etc..)
Here’s how to get it back:
Click Start–>Run–>type “gpedit.msc” without the “
This opens the group policy editor. Then go to:
Local Computer Policy–>Computer Configuration–>Administrative Templates–>Network–>QOS Packet Scheduler–>Limit Reservable Bandwidth
Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the ‘Explain’ tab :
“By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default.”
So the trick is to ENABLE reservable bandwidth, then set it to ZERO.
This will allow the system to reserve nothing, rather than the default 20%.
I have tested on XP Pro, and 2000
other o/s not tested.
Please give me feedback about your results
Windows Xp: Speed Up Your, Speed Up Your Network and Internet Access
I have a dial up connection and it improve my speeds about 25% in surfing the internet. give it a try. Im IT , only do it if you feel comfortable with changing registry.
Increasing network browsing speed
Does your computer slow down when you browse your local area network and connect to other computers that are sharing data? One of the most common causes of this slowdown is a feature of Windows Explorer that looks for scheduled tasks on remote computers. This effort can take some time on some computers and can really slow down your browsing. The window with which you are browsing the network may appear to freeze momentarily, as the system is waiting for a response from the remote computer.
Windows XP: Speeding Disk Access
Although this problem is a complex one, the solution is very simple. Instead of having to wait for the remote scheduled tasks, which is useless information to anyone who is not a system administrator remotely configuring scheduled tasks, you can disable this feature.
In order to do this, you will have to change the System Registry and delete a reference to a key so that this feature will not be loaded. To do this, follow these steps:
1. Open up the Registry Editor by clicking the Start Menu and selecting Run. Then type regedit in the text box and click the OK button.
2. Once the Registry Editor has loaded, expand the HKEY_LOCAL_MACHINE key.
3. Next, expand Software and then Microsoft.
4. Locate Windows and expand that as well.
5. You will want to be editing the main system files, so expand CurrentVersion.
6. Because this feature is a feature of the Windows component known as Explorer, expand the Explorer key.
7. Next, you will want to modify the remote computer settings, so expand the RemoteComputer key and then expand the NameSpace key to show all of the features that are enabled when you browse to a remote computer.
8. In the NameSpace folder you will find two entries. One is “{2227A280-3AEA-1069-A2DE-08002B30309D}” which tells Explorer to show printers shared on the remote machine. The other, “{D6277990-4C6A-11CF-8D87-00AA0060F5BF},” tells Explorer to show remote scheduled tasks. This is the one that you should delete. This can be done by right-clicking the name of the key and selecting Delete.
Tip:
If you have no use for viewing remote shared printers and are really only interested in shared files, consider deleting the printers key, “{2227A280-3AEA-1069-A2DE-08002B30309D}”, as well. This will also boost your browsing speed.
Once you have deleted the key, you just need to restart and the changes will be in effect. Now your network computer browsing will be without needless delays.
The BitTorrent protocol is a popular method for downloading large files, and many tweaks exist to enhance its performance. However, most clients only support downloading, not watching, a video stream using BitTorrent. How to extend BitTorrent such that one client can be used to watch both video-on-demand streams (existing movies) and live video streams (generated real-time)?
It turns out that the modifications required to support video-on-demand are minor and remain backward compatible. In fact, we’re not the only one supporting video-on-demand in BitTorrent, Vuze does the same. However, Vuze requires a server park to serve the videos at a sufficient speed, and we aim to avoid that.
Live streaming is another matter. The BitTorrent protocol requires the file data to be fixed in size and known beforehand, neither of which holds for live streaming. So the BitTorrent protocol had to be broken, but by keeping the changes minimal, other clients can be easily adapted as well.
In both cases, a video player needs to be tied to the BitTorrent client, and specialised download and upload policies are needed to achieve high performance. There is a lot more to it, which I’ll describe below by first covering the technical setup, and then an outline of the required modifications to support video streaming in BitTorrent.
There’s a catch however. We are spoiled with HD-quality movies, but to stream them, you need to have a pretty decent download speed. For example, a two hour movie fitted on a DVD is encoded at 5 Mbit/s. To watch it while downloading, you need a sustained download rate of at least 640 Kbyte/s. That’s why our demo streams are encoded at around 0.5 - 1.0 Mbit/s.
Disclaimer: Another catch is that SwarmPlayer is complex software, since it combines several large open source projects (VLC, ffmpeg, wxPython, and more) and aims to support Windows, Mac and Linux. As a result, it is impossible to guarantee that the SwarmPlayer will work as expected on all configurations and on any movie format. YMMV.
Setup ¶
Video on Demand Server ¶
To set up a VoD server, first create a torrent out of your movie:
python createtorrent.py --name weather.avi --duration 4:15 --thumb weather.jpg
The duration of the movie is included to allow clients to determine whether they have the download speed required to watch the video. After all, bitrate = filesize/duration. Other BitTorrent clients will ignore this field. Once the torrent has been created, a seed and a tracker are started.
Live Video Server ¶
For live video streaming, more is needed. We need a video source, such as a DV camera, webcam, or TV tuner. The raw video requires too much bandwidth, so it needs to be transcoded as well. Common Linux utilies can be used:
BITRATE=512k
RESOLUTION=360x288
# command to grab and transcode
CMD="dvgrab -noavc --format raw - |
ffmpeg -f dv -i - -f mpegts -vcodec mpeg4 -s $RESOLUTION -b $BITRATE -bt $BITRATE -an -"
# example usage
$CMD > stream.mpegts
Unless you are filming your server room, the camera is likely not attached to the same computer that will offer the stream to the users. So, we have to transport the stream to our source server, and feed it to the SwarmPlayer:
ssh user@source.example.org $CMD |
python Tribler/Tools/createlivestream.py --name stream.mpegts
--source - --port 8764 --duration 1:00:00 --destdir . --thumb tramsmall.jpg
The duration parameter actually represents the size of the data file we want to emulate. The actual video stream is unbound in duration, and we’ll use a rotating sliding window of 15 minutes over the 1:00:00 in which we generate the data in real time. Retaining 15 minutes is actually quite conservative, but allows us to focus on other performance bottlenecks at a minor cost in disk space.
The createlivestream.py script generates several files:
* stream.mpegts.tstream, which is a torrent-like file to distribute to the clients.
* stream.mpegts, which holds the last 1:00:00 of live video. Only the last 15 minutes are accessed, but we don’t zero out invalidated data.
* stream.mpegts.sauth, which contains the private key used to sign the generated data.
Furthermore, the script will cut the video stream into pieces and offers them to the users. No additional tracker is needed since an internal one is used automatically.
Clients ¶
The user has to download the torrent (or tstream) file, and feed it to the SwarmPlayer, which will automatically hook in, start downloading and start playing.
Theory ¶
In BitTorrent, each client downloads the rarest pieces and uploads to its neighbours in a tit-for-tat-like fashion. This works because all clients need the same data, and do not care about the order in which they receive it. However, in streaming video systems, these assumptions do not always hold. For video-on-demand, the clients need data depending on their position in the video, and all of the clients need the data from beginning to end. For live video streaming, all clients need the same data, but they are only interested in a sliding window of pieces.
Video-on-Demand ¶
To support video-on-demand, we use the Give-to-Get algorithm, described in this paper. The mentioned paper compares the performance of Give-to-Get to the original BitTorrent mechanisms. To summarise the essential adjustments:
* A peer buffers the start of the video, and starts playback once the download speed is high enough.
* Peers pick pieces to download using a strategy which mixes in-order downloading (required for playback) and rarest-first downloading (which increases the availability of rare pieces).
* Peers upload to neighbours who upload well to others, instead of using BitTorrent’s tit-for-tat-like unchoking mechanism. Since peers will spend most of their bandwidth downloading the video in-order, any pair of two peers A and B will have either A ahead of B or vice versa. If A is ahead of B, A will not be interested in the data downloaded by B. So, tit-for-tat does not really work well.
Live Video ¶
Supporting live video is, as mentioned, more complicated. A paper will follow. Some of the things that needed adjusting are:
* Piece verification: BitTorrent computes hashes of the pieces and includes these in the torrent, making each client able to verify each piece. With live video, this is not possible as the data has not been generated when the tstream file is distributed. To verify the data, we include a public key in the tstream file. Each piece contains a time stamp, piece number and a payload, as well as a signature covering all of these fields. We use elliptic curve cryptography.
* Sliding window: The BitTorrent core assumes a fixed number of pieces everywhere in the code. To reduce the amount of change necessary, we use a sliding window which rotates over a set of pieces of fixed length, for example a 15 minute window over a 1 hour torrent. Each peer keeps track of the sliding window by looking at the pieces available at its neighbours. Pieces which fall out of the sliding window are discarded and assumed to be discarded by the neighbours as well.
* Bitrate estimation: Although we order ffmpeg to transcode the video stream to 512kbit/s, the actual video bitrate can be quite different. Each client measures the bitrate by comparing the timestamps included in the pieces in order to predict the speed at which future pieces will need to be downloaded.
* Frame drop and stall policy: Whether a certain playback position can be maintained depends on the peer’s position in the network. Close to the source, a peer can maintain a playback position close to live, but if a peer is further from the source this is not possible. This creates a decision problem when a piece is not downloaded in time. In case of regular piece loss, we need to drop the piece and continue playback. However, if our playback position is not sustainable, the client needs to stall (pause) in order to catch up with its neighbours. The SwarmPlayer stalls if the playback buffer after the missing piece is less than half full. Otherwise, we just drop the piece and continue playback.
* Small pieces: Since we can only verify a piece once it is fully downloaded, small pieces allow faster verification and thus smoother playback. We use pieces of 32Kbyte instead of the more common sizes of 512Kbyte or larger. The hashes of the pieces are not included in the torrent, so an increase in number of pieces has no effect on the size of the torrent.
Software ¶
The SwarmPlayer combines our modified BitTorrent client with wxPython for the GUI, VLC for the video playback, ffmpeg for video analysis, as well as several small Python modules. The Python sources can be obtained here, and our modified version of VLC can be obtained here.
The term web standards can mean different things to different people. For some, it is 'table-free sites', for others it is 'using valid code'. However, web standards are much broader than that. A site built to web standards should adhere to standards (HTML, XHTML, XML, CSS, XSLT, DOM, MathML, SVG etc) and pursue best practices (valid code, accessible code, semantically correct code, user-friendly URLs etc).
In other words, a site built to web standards should ideally be lean, clean, CSS-based, accessible, usable and search engine friendly.
About the checklist
This is not an uber-checklist. There are probably many items that could be added. More importantly, it should not be seen as a list of items that must be addressed on every site that you develop. It is simply a guide that can be used:
* to show the breadth of web standards
* as a handy tool for developers during the production phase of websites
* as an aid for developers who are interested in moving towards web standards
The checklist

3. Does the site use Valid (X)HTML?
4. Does the site use Valid CSS?
5. Does the site use any CSS hacks?
6. Does the site use unnecessary classes or ids?
7. Is the code well structured?
8. Does the site have any broken links?

1. Quality of code
1.1 Does the site use a correct Doctype?
A doctype (short for 'document type declaration') informs the validator which version of (X)HTML you're using, and must appear at the very top of every web page. Doctypes are a key component of compliant web pages: your markup and CSS won't validate without them.

1.2 Does the site use a Character set?
If a user agent (eg. a browser) is unable to detect the character encoding used in a Web document, the user may be presented with unreadable text. This information is particularly important for those maintaining and extending a multilingual site, but declaring the character encoding of the document is important for anyone producing XHTML/HTML or CSS.
CODE

More:
CODE
http://www.w3.org/International/O-charset.html
1.3 Does the site use Valid (X)HTML?
Valid code will render faster than code with errors. Valid code will render better than invalid code. Browsers are becoming more standards compliant, and it is becoming increasingly necessary to write valid and standards compliant HTML.
CODE

CODE
http://validator.w3.org/
1.4 Does the site use Valid CSS?
You need to make sure that there aren't any errors in either your HTML or your CSS, since mistakes in either place can result in botched document appearance.

1.5 Does the site use any CSS hacks?
Basically, hacks come down to personal choice, the amount of knowledge you have of workarounds, the specific design you are trying to achieve.

1.6 Does the site use unnecessary classes or ids?
I've noticed that developers learning new skills often end up with good CSS but poor XHTML. Specifically, the HTML code tends to be full of unnecessary divs and ids. This results in fairly meaningless HTML and bloated style sheets.
CODE
http://www.clagnut.com/blog/228/
1.7 Is the code well structured?
Semantically correct markup uses html elements for their given purpose. Well structured HTML has semantic meaning for a wide range of user agents (browsers without style sheets, text browsers, PDAs, search engines etc.)
CODE

More:
CODE
http://www.w3.org/2003/12/semantic-extractor.html
1.8 Does the site have any broken links?
Broken links can frustrate users and potentially drive customers away. Broken links can also keep search engines from properly indexing your site.
More:
CODE
http://validator.w3.org/checklink
1.9 How does the site perform in terms of speed/page size?
Don't make me wait... That's the message users give us in survey after survey. Even broadband users can suffer the slow-loading blues.
CODE
http://www.websiteoptimization.com/speed/
1.10 Does the site have JavaScript errors?
Internet Explore for Windows allows you to turn on a debugger that will pop up a new window and let you know there are javascript errors on your site. This is available under 'Internet Options' on the Advanced tab. Uncheck 'Disable script debugging'.
2. Degree of separation between content and presentation
2.1 Does the site use CSS for all presentation aspects (fonts, colour, padding, borders etc)?
Use style sheets to control layout and presentation.
CODE
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-style-sheets
2.2 Are all decorative images in the CSS, or do they appear in the (X)HTML?
The aim for web developers is to remove all presentation from the html code, leaving it clean and semantically correct.
CODE
http://www.maxdesign.com.au/presentation/benefits/index07.htm
3. Accessibility for users
3.1 Are "alt" attributes used for all descriptive images?
Provide a text equivalent for every non-text element
CODE
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-text-equivalent
3.2 Does the site use relative units rather than absolute units for text size?
Use relative rather than absolute units in markup language attribute values and style sheet property values'.

3.3 Do any aspects of the layout break if font size is increased?
Try this simple test. Look at your website in a browser that supports easy incrementation of font size. Now increase your browser's font size. And again. And again... Look at your site. Does the page layout still hold together? It is dangerous for developers to assume that everyone browses using default font sizes.
3.4 Does the site use visible skip menus?
A method shall be provided that permits users to skip repetitive navigation links.
CODE
http://www.section508.gov/index.cfm?FuseAction=Content&ID=12
Group related links, identify the group (for user agents), and, until user agents do so, provide a way to bypass the group.
CODE
http://www.w3.org/TR/WCAG10-TECHS/#tech-group-links
...blind visitors are not the only ones inconvenienced by too many links in a navigation area. Recall that a mobility-impaired person with poor adaptive technology might be stuck tabbing through that morass.

CODE
http://www.niehs.nih.gov/websmith/508/o.htm
3.5 Does the site use accessible forms?
Forms aren't the easiest of things to use for people with disabilities. Navigating around a page with written content is one thing, hopping between form fields and inputting information is another.

3.6 Does the site use accessible tables?
For data tables, identify row and column headers... For data tables that have two or more logical levels of row or column headers, use markup to associate data cells and header cells.
CODE

3.7 Is there sufficient colour brightness/contrasts?
Ensure that foreground and background colour combinations provide sufficient contrast when viewed by someone having colour deficits.

Ensure that all information conveyed with colour is also available without colour, for example from context or markup.
CODE
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-colour-convey
There are basically three types of colour deficiency; Deuteranope (a form of red/green colour deficit), Protanope (another form of red/green colour deficit) and Tritanope (a blue/yellow deficit- very rare).

3.9 Is there delayed responsiveness for dropdown menus?
Users with reduced motor skills may find dropdown menus hard to use if responsiveness is set too fast.
3.10 Are all links descriptive?
Link text should be meaningful enough to make sense when read out of context - either on its own or as part of a sequence of links. Link text should also be terse.
CODE
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-meaningful-links
4. Accessibility for devices.
4.1 Does the site work acceptably across modern and older browsers?
Before starting to build a CSS-based layout, you should decide which browsers to support and to what level you intend to support them.
CODE
http://www.maxdesign.com.au/presentation/process/index_step01.cfm
4.2 Is the content accessible with CSS switched off or not supported?
Some people may visit your site with either a browser that does not support CSS or a browser with CSS switched off. In content is structured well, this will not be an issue.
4.3 Is the content accessible with images switched off or not supported?
Some people browse websites with images switched off - especially people on very slow connections. Content should still be accessible for these people.
4.4 Does the site work in text browsers such as Lynx?
This is like a combination of images and CSS switched off. A text-based browser will rely on well structured content to provide meaning.

CODE
http://www.delorie.com/web/lynxview
4.5 Does the site work well when printed?
You can take any (X)HTML document and simply style it for print, without having to touch the markup.

More:
CODE
http://www.d.umn.edu/itss/support/Training/Online/webdesign/css.html#print
4.6 Does the site work well in Hand Held devices?
This is a hard one to deal with until hand held devices consistently support their correct media type. However, some layouts work better in current hand-held devices. The importance of supporting hand held devices will depend on target audiences.
4.7 Does the site include detailed metadata?
Metadata is machine understandable information for the web
CODE
http://www.w3.org/Metadata/
Metadata is structured information that is created specifically to describe another resource. In other words, metadata is 'data about data'.
4.8 Does the site work well in a range of browser window sizes?
It is a common assumption amongst developers that average screen sizes are increasing. Some developers assume that the average screen size is now 1024px wide. But what about users with smaller screens and users with hand held devices? Are they part of your target audience and are they being disadvantaged?
5. Basic Usability
5.1 Is there a clear visual hierarchy?
Organise and prioritise the contents of a page by using size, prominence and content relationships.
CODE
http://www.great-web-design-tips.com/web-site-design/165.html
5.2 Are heading levels easy to distinguish?
Use header elements to convey document structure and use them according to specification.
CODE
http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-logical-headings
5.3 Is the site's navigation easy to understand?
Your navigation system should give your visitor a clue as to what page of the site they are currently on and where they can go next.
CODE
http://www.1stsitefree.com/design_nav.htm
5.4 Is the site's navigation consistent?
If each page on your site has a consistent style of presentation, visitors will find it easier to navigate between pages and find information
CODE
http://www.juicystudio.com/tutorial/accessibility/navigation.asp
5.5 Does the site use consistent and appropriate language?
The use of clear and simple language promotes effective communication. Trying to come across as articulate can be as difficult to read as poorly written grammar, especially if the language used isn't the visitor's primary language.
CODE
http://www.juicystudio.com/tutorial/accessibility/clear.asp
5.6 Does the site have a sitemap page and contact page? Are they easy to find?
Most site maps fail to convey multiple levels of the site's information architecture. In usability tests, users often overlook site maps or can't find them. Complexity is also a problem: a map should be a map, not a navigational challenge of its own.
CODE
http://www.useit.com/alertbox/20020106.html
5.7 For large sites, is there a search tool?
While search tools are not needed on smaller sites, and some people will not ever use them, site-specific search tools allow users a choice of navigation options.
5.8 Is there a link to the home page on every page in the site?
Some users like to go back to a site's home page after navigating to content within a site. The home page becomes a base camp for these users, allowing them to regroup before exploring new content.
5.9 Are links underlined?
To maximise the perceived affordance of clickability, colour and underline the link text. Users shouldn't have to guess or scrub the page to find out where they can click.
CODE
http://www.useit.com/alertbox/20040510.html
5.10 Are visited links clearly defined?
Most important, knowing which pages they've already visited frees users from unintentionally revisiting the same pages over and over again.
CODE
http://www.useit.com/alertbox/20040503.html
6. Site management
6.1 Does the site have a meaningful and helpful 404 error page that works from any depth in the site?
You've requested a page - either by typing a URL directly into the address bar or clicking on an out-of-date link and you've found yourself in the middle of cyberspace nowhere. A user-friendly website will give you a helping hand while many others will simply do nothing, relying on the browser's built-in ability to explain what the problem is.
CODE
http://www.alistapart.com/articles/perfect404/
6.2 Does the site use friendly URLs?
Most search engines (with a few exceptions - namely Google) will not index any pages that have a question mark or other character (like an ampersand or equals sign) in the URL... what good is a site if no one can find it?
CODE
http://www.sitepoint.com/article/search-engine-friendly-urls
One of the worst elements of the web from a user interface standpoint is the URL. However, if they're short, logical, and self-correcting, URLs can be acceptably usable

CODE
http://www.merges.net/theory/20010305.html
6.3 Does the site's URL work without "www"?
While this is not critical, and in some cases is not even possible, it is always good to give people the choice of both options. If a user types your domain name without the www and gets no site, this could disadvantage both the user and you.
6.4 Does the site have a favicon?
A Favicon is a multi-resolution image included on nearly all professionally developed sites. The Favicon allows the webmaster to further promote their site, and to create a more customized appearance within a visitor's browser.
CODE
http://www.favicon.com/
Favicons are definitely not critical. However, if they are not present, they can cause 404 errors in your logs (site statistics). Browsers like IE will request them from the server when a site is bookmarked. If a favicon isn't available, a 404 error may be generated. Therefore, having a favicon could cut down on favicon specific 404 errors. The same is true of a 'robots.txt' file.

There are a lot of PC users that know little about “Spyware”, “Mal-ware”, “hijackers”, “Dialers” & many more. This will help you avoid pop-ups, spammers and all those baddies.
What is spy-ware?
Spy-ware is Internet jargon for Advertising Supported software (Ad-ware). It is a way for shareware authors to make money from a product, other than by selling it to the users. There are several large media companies that offer them to place banner ads in their products in exchange for a portion of the revenue from banner sales. This way, you don’t have to pay for the software and the developers are still getting paid. If you find the banners annoying, there is usually an option to remove them, by paying the regular licensing fee.
Known spywares
There are thousands out there, new ones are added to the list everyday. But here are a few:
Alexa, Aureate/Radiate, BargainBuddy, ClickTillUWin, Conducent Timesink, Cydoor, Comet Cursor, eZula/KaZaa Toptext, Flashpoint/Flashtrack, Flyswat, Gator, GoHip, Hotbar, ISTbar, Lions Pride Enterprises/Blazing Logic/Trek Blue, Lop (C2Media), Mattel Brodcast, Morpheus, NewDotNet, Realplayer, Songspy, Xupiter, Web3000, WebHancer, Windows Messenger Service.
