Security for non-server computer

Hi. I've tried to look through all the security help files, but it's just confusing me. Here's my deal:

I've got RH9 on an old laptop. I plug it in to ethernet jack when I come to work (a university) to surf and check e-mail. I occasionally FTP to update my webpage.

I'd like to set up this laptop so that nobody can remotely login (telnet or SSH). This will keep network integrity folks out of my hair--they already like me b/c I'm using a personal laptop that is non-Win, want to stay on their good side by not letting anybody login remotely to my computer.

Is it as simple as getting rid of SSH and xinetd? Or will turning those services off disable other features I might want to use? Maybe I should configure iptables somehow? (I don't know what to do w/ iptables right now, incidentally.)

A quick reply and/or push in the direction of a newb resource for non-server computers is greatly appreciated. I don't want to do anything to complicated--just want to prevent my laptop from being the weak link in the univ's system. Or, more appropriately, I don't want to be hounded by network admins. Thanks.

Easier than that ...

tcpd can take care of all those worries for you,
all you need to do is to modify

Make hosts.allow only allow IP's from your
home-network if you have one (and it's different
from the IP range at work, of course).

And in hosts.deny
ALL:<varsity's IP range>

If you had at home, and the varsity
had 172.20.x.x
you could go
