am i doing something wrong?

Are you sure that you actually CAN use your work computer IP # on another computer? Several of my machines are on a subnet run by very paranoid sysadmins. They programmed the router to accept packets from a given IP# only if it matched the MAC addresses that I supplied to them.. If I tried to use another computer with the same IP#, or if I switched network cards, the router would drop ALL traffic.
OF course, they didn't tell me this and it made upgrading a network card a bitch to troubleshoot.

I like to hit those kinds of dudes with swords.
If you have to deal with a guy like that... chances are you're screwed. He'll take one look at it and say "Linux? HA! That's a hacker tool!"

Pretty sure this is not the case -- lots of people around here do it, and are apparently encouraged to do it, since we have basically "run out" of IP addresses. Work for me is not a small office, but a superfuckinghuge university, and the sysadmins' job seems to be to hide in closets and troll for viruses.
Aside to Jimmy James: we actually have labs full of Dell workstations running RedHat9. All in all, the building is probably 30% Mac, 30% Win98, 30%Linux/Sparc, 5% Win2000+ and 5% SGI. If only all buildings in the world were like this...

It works now. Well, thank you all for your suggestions. I ran ifconfig and I pinged my gateway, and it was successful, so I ran the Konqueror directly over to Mozilla.org.
I guess the problem was: the network cable was not plugged in when I started Linux. It must test the network connection on startup or something. Today, I hooked everything up before booting, and it worked like a charm: the blinkenlights on the adapter were even working.
So if anyone can confirm what I have seen here, I would be interested, if for nothing more than posterity's sake.
Again, thanks for all the ideas and assistance.

Yes, the network connection has to be enabled manually if it wasn't started at boot-time. If you need to do that in the future just type "ifup eth0" to enable it.
