help with linux networking

[Scootin159]

I setup a linux box on our campus network. It's IP# is 10.2.30.137, yet when I try to ping "bart.roberts.edu" it tries to ping 10.1.2.20 (an IP# from a machine named bart I used last year). This is real annoying because I can't ues it's DNS name. Any ideas how to fix this? BTW, I'm pretty much a linux no0b, so it might explain some ignorance on my part.

Fix your /etc/resolv.conf

Also check to make sure you don't have any entries (If you do, change them) in your /etc/hosts

I have 127.0.0.1 localhost.localdomain localhost in there, is this ok?

I have:
nameserver 10.2.1.200
nameserver 10.1.1.186
search roberts.edu

Those are the correct IP#'s for our DNS servers, so should I change anything?

Those are your *CURRENT* dns servers? If so, it looks fine to me. If bart (the wrong bart) is not in either of those files I dont know where it would get that config from, but Id grep for it in the /etc directory.

those are our 'current' DNS servers. The 'other' bart is the IP# that I had on a win2k server box last year (long gone). When I ping it with any other box on the network I get the same, wrong, IP.



<< Id grep for it in the /etc directory. >>


how would I do that? What is that?

man grep

Basically something along the lines of: grep bart /etc/*

grep is possibly one of the most useful UNIX commands. Get to know it, its saved me a lot of work MANY times.

thanks for the info guys. From the sounds of it (from another conversation) my old win2k server box locked bart.roberts.edu into being 10.1.20.22 in the active directory. So I'm just going to manually assign it (working on that now, I'll ask if I can't figure it out).
