Re: irc at uni
the unix server is your access to an unrestricted world.
to talk to the server you use putty which uses ssh - which is just a secure protocol.
you could use putty to talk directly to the server through typing unix commands but i doubt you'd want to do that.
it's more likely that you will use putty to act as a gateway to the unrestricted world: instead of accessing the internet through your university server putty allows you to talk to it, which in turn talks to the unix server. so you're tunneling out of your current environment to another.
i've not done the technicalities of this in a while, but you would need to give putty the details of your server (address, port number, password i would guess) so it can talk to it.
then you must set up putty so it sits on a certain location i.e. localhost:4114 (with 4114 being the port number, the place, on your computer, localhost). then set up mirc so it looks at localhost:4114 when it wants to talk to the outside world.
i guess the server would just know what to do when putty tells it to send /receive internet packages. make sure your account specifically allows http-tunneling to be sure.
that's all i know. should be enough hopefully.
