SSH server and client

ok ive never tried to run an ssh tunnle or server before. im just wondering if anyone knows how to start the tunnle? lol im using cygwin (http://cygwin.com/) as the server and putty (http://www.chiark.greenend.org.uk/~sgtatham/putty/) as my client. im planning on having the server on my home computer, windows xp home, and the client at school on 2000pro. i havent installed putty at school yet but will once i get the server running. i have it installed but dont know how to really start it?? ive been using these two tutorials:

1. http://pigtail.net/LRP/printsrv/cygwin-sshd.html
2. http://x.cygwin.com/docs/ug/cygwin-x-ug.txt
EDIT 3. http://www.buzzsurf.com/surfatwork/ forgot that one lol
i know some of you are going to go oh the problem is its a linux program. which is true but the tutorial shows you how to make it work on a windows os.

forgot to click email notification i hate that wish you could defualt it to always notify lol

also i just thought of a question. with putty installed on the computer in my directory on the network it wont affect anyone but me using that computer right? like if someone logs in they cant use it but have access online? and also to connect online do i always have to use this or only when i want to connect to my computer? im basically using this as a way around network restrictions of all the good sites. i just like to push my network admin and make him work hard to stop people from using the network how they want to. he already busted me for playing cs on the computers and slowing the network to a crawl lol. stupid cheap servers.

On your Windows machine:
1. Make sure you have the openssh package installed.
2. Launch Cygwin/X
3. Run the following in an X terminal:

Username@CygwinHost ~
$ ssh -Y -l username remote_hostname_or_ip_address

4. Enter your password when prompted by ssh.
5. Your ssh session should now show you a shell prompt for your
remote machine.
6. You can now launch remote X clients in your ssh session, for
example, xterm& will launch an xterm running on your remote host
that will display on your Cygwin/X screen.
7. Launch other remote clients in the same manner. I recommend
starting the remote clients in the background, by appending & to
the command name, so that you don't have to open several ssh
sessions.


this is where it doesnt work it says "bash: ssh: command not found"
