Unable to connect to my campus' network. (DHCP problem?)
 
Hi, I recently returned to college, and have been having a spot of trouble getting linux installations to access the internet. Strangely enough, I installed debian from a net-install disc just fine, getting an ip via dhcp and connecting to the repository--but I could not connect to the internet, or the campus network afterwards.

I'm presently running Fedora 10, my motherboard is an a8n-sli premium, with two onboard nics, I am plugged in to the nvidia onboard network controller. I can (and am currently) connected to the internet through the dorm network on a windows install on the same computer.

Please help me get to the bottom of this problem so I can use a proper operating system!

Thanks in advance.

Here is some information which I've collected that seems relevant.

Post your lsmod and

Try

$/etc/init.d/network restart

$dhclient

You might want to
$ifconfig eth1 down
before you restart the network, but you shouldn't have to.

See what happens.

Hi, thanks a lot for the quick reply. Apparently the problem was server side, with how IPs were assigned by DHCP as most recently, when I booted to try and fix it. I managed to connect just fine.
