network issue/no connection


Okay, here's a trippy problem: I'm at work using my 60gb hard drive with Xubuntu loaded on it. I have a job where I move around on site and can connect to a number of work stations all over the place. Essentially it's just a matter of plugging in and rebooting into my hard drive. They use a Websense proxy filter which I adjust for (http://proxy:8080) and for the most part it's not a problem for Firefox to negotiate and pop up a login. We have a bunch of Dell GX620's and a few older GX270's and 280's.

Now, the problem is with two of the GX280's and one GX620. I can't connect through the proxy or get any connection at all. I'm writing this from the 270 that works and here's the ifconfig from both:

GX270 (works fine)

rick@rick-usb:~$ ifconfig

rick@rick-usb:~$

I can provide more read outs (netstat, etc) if necessary, but I figured I'd start there. Each of the three computers that I cannot access the internet with have that extra "eth1:avah" entry. I'm not sure what it means, but if anyone can help me out that would be great. Thanks.

You don't get an IP address from DHCP in the second case. Because of this a 169.254 IP address is created was ich mal zum Lernen and for some reasons I also don't understand assigned to the :avah IF. Looks like there there is no dhcp server.
