Introduction:
Telnet is used to connect to remote machines through emulation. This means thatit can connect to a server, any server instantly because of it's ability to emulate (copy)remote computers.
Lets Start:
In Windows, Telnet can be found by going to Start -> Run and then typing telnet.The application should then pop up. If you don't have Windows, there are many Telnet alternatives for mac, linux etc. Since I don't know any,search the internet for Telnet for Linux or Telnet for Mac and you should find something instantly.
If you have a PC and are using Windows 98/95, 2000, Me, or XP continue...
As you can see, Telnet has 4 menu options. These are Connect, Edit, Terminal, and Help.
If you click Connect, you should see more options. Here they are.
Connect:
Remote System..
Disconnect
Exit
Names of servers you have been on.
To connect to a server, click Remote System...
This will then take you to a dialog box that has these fields:
Hostname:
Port:
TermType:
There should also be a Connect button and a Cancel Button.
Lets go over these & what you should put in them.
-Hostname-
The Hostname can be the address of the website your going to be connecting to:
http://www.google.com
or it can be the IP address. Keep in mind that you can only connect to servers and not to clients (other PCs)
an IP Address looks like this: 64.233.167.99
-Port-
Port can bb either the port number you wanna connect to on the server (Port 80 is the Internet, Port 23 is Simple Mail Protocol then there are some more ports for different things..)
or you can keep it Telnet and see what happens.
-TermType-
TermType is the type of Terminal telnet will be acting like.This doesn't matter most of the time, so you can keep it to default or try other ones if you want.
When you have all this set up, you can Click Connect & see what happens.
Note: Sometimes many servers don't like anon people just logging on, so be careful when logging onto servers, because sometimes it might be some big company that likes bullying people or just SOMEONE who likes bullying people and then they might want to find you or trace you or something and I know for a fact you don't need that happening.
Another Note: When you go to a server and type something, such as a login name or a password, you might not see anything even though you are typing. this is a feature that telnet or the other server uses. It's for some kind of safety measure.
Ok that's all for the Connect Menu, lets go over the Terminal menu.
The terminal menu should have 3 options:
Prefernces
Start Logging
Stop Logging.
-Prefernces-
If you go to this, a dialog box will come up with various options. Here, you can change thetext color & background color of the program, and you can enable Local Echo, which shows
you everything you've typed, Blinking cursor if you want the cursor to blink check it, if not un check, Block cursor if you want the cursor to be shown as a block, VT100 Arrows, don't worry about these they are useless, Buffer Size, this allows you to set the number of lines of text you want to be shown before the screen starts to scroll, The Terminal emulation type, always have this set on the default unless you know what the second one is and you know what your doing.
-Start Logging-
This logs everything you do on Telnet in a log file on your computer.
-Stop Logging-
This will stop logging processes.
Don't use it illegaly. THANK'S

Know About Virus Win32/ExploreZip
What is Win32/ExploreZip?
ExploreZip is a Win32-based e-mail worm. It searches for any and all Microsoft Office documents on your hard drive and network drives. When it finds any Word, Excel, or Powerpoint documents using the following extensions: .doc, .xls, and .ppt, it erases the contents of those files. It also emails itself to anyone who sends you an email.
How do I get it?
ExploreZip arrives as an email attachment. The message will most likely come from someone you know, and the body of the message will read:
"I received your email and I shall send you a reply ASAP. Till then, take a look at the attached zipped docs."
The attachment will be name: "zipped_files.exe" and have a WinZip icon. Double clicking the zipped_files.exe program infects your computer. You will then see a dialog box displaying the following message:
"Cannot open file: it does not appear to be a valid archive. If this file is part of a ZIP format backup set, insert the last disk of the backup set and try again. Please press F1 for help."
Who's at risk?
People running Microsoft Windows95, Windows98, or WindowsNT are at risk. MacOS and WebTV are immune to the virus.
What exactly does the virus do to my computer?
When the zipped_files.exe program is ran, it creates a copy of itself named explore.exe in your Windows System folder.
On Windows 95/98 systems, the following entry is written to the WIN.INI file:
run=C:\WINDOWS\SYSTEM\Explore.exe
On Windows NT systems, the following entry is written to the system registry:
HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\CurrentVersion\Windows\run="C:\WINNT\System32\Explore.exe"

Automatic Close Programs At Shutdown.................
don't you hate it when, while trying to shut down, you get message boxes telling you that a program is still running? Making it so that Windows automatically kills applications running is a snap. Simply navigate to the registry key...............
HKEY_CURRENT_USER/Control Panel/Desktop/directory,
then change the key AutoEndTasks to the value 1.
HKEY_CURRENT_USER/Control Panel/Desktop/directory,
then change the key AutoEndTasks to the value 1.
Increase Options In Add Or Remove Programs.........
Not a fan of MSN Messenger? don't want Windows Media Player on your system? Fair enough, but if you go to Add/Remove Programs in the Control Panel, by default none of Windows XP's 'built in' programs are visible. it's fairly easy to change, though... just open the file X:\Windows\inf\sysoc.inf (where X: is the drive letter where Windows XP is installed) in Notepad. You should see a section of the file something like this:
[Components]NtComponents=ntoc.dll,NtOcSetupProc,,4
WBEM=ocgen.dll,OcEntry,wbemoc.inf,hide,7
Display=desk.cpl,DisplayOcSetupProc,,7
Fax=fxsocm.dll,FaxOcmSetupProc,fxsocm.inf,,7
NetOC=netoc.dll,NetOcSetupProc,netoc.inf,,7
iis=iis.dll,OcEntry,iis.inf,,7
com=comsetup.dll,OcEntry,comnt5.inf,hide,7
dtc=msdtcstp.dll,OcEntry,dtcnt5.inf,hide,7
IndexSrv_System = setupqry.dll,IndexSrv,setupqry.inf,,7
TerminalServer=TsOc.dll, HydraOc, TsOc.inf,hide,2msmq=msmqocm.dll,MsmqOcm,msmqocm.inf,,6
ims=imsinsnt.dll,OcEntry,ims.inf,,7
fp_extensions=fp40ext.dll,FrontPage4Extensions,fp40ext.inf,,7
AutoUpdate=ocgen.dll,OcEntry,au.inf,hide,7
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
RootAutoUpdate=ocgen.dll,OcEntry,rootau.inf,,7
IEAccess=ocgen.dll,OcEntry,ieaccess.inf,,7
This is a list of all components installed at the moment. I've taken the example of MSN Messenger - the program entry called 'msmsgs', third-last line. You can see the word 'hide' highlighted - this is the string which tells Windows not to display the component in the Add/Remove Programs list. Fix this up by simply deleting the word 'hide' like so :
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
To this:msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,,7
Now, after restarting, you should be able to see MSN Messenger in the Add/Remove Programs list. If you want to be able to quickly view and remove all components, simply open the sysoc.inf file and do a global find and replace for the word ",hide" and replace it with a single comma ",".
