How do I force a default gateway change? It seems stuck on 192.168.0.1 in Ubuntu

Question

This has me stumped. I am connected to a college network, which requires me to have my MAC registered (Done, windows works fine).

So, when I boot to Ubuntu, I try to access a page in Chromium, and I get an Error 102(net::ERR_CONNECTION_REFUSED): Unknown error.

Firefox fails too.

Resolve.conf has several servers, all of which I can successfully ping, and I can ping digg.com and google.com using their names.

Also, there is constant network activity, but I can't tell what process/ports are downloading and uploading. (netstat -tupl didn't seem to show anything)

I don't have any network managers installed (for w/e reason).

Update: I randomly tried to update my system, and it of course failed, but I read the text.

The error states that: failed to fetch package blah blah at IP ADDRESS: 192.168.0.1:80 (connection refused).

Obviously, the ip addr of canonical is not 192... but I don't have a router between me and the internet now (I used dhclient to update my settings) so what is rerouting all my http requests to 192.168.0.1?

Using wicd, setting a static ip, dns, and gateway still results in all http traffic getting redirected to 192.168.0.1:80, using ip route show | grep default | awk '{ print $3 }' shows a different ip than 192.168.0.1.

Answer 1

You're looking for the route command. However, it sounds to me like there is a deeper issue going on with your setup. What error did Firefox give you?

Also, dhclient has been absorbed into dhcp3-client. Make sure that the version of dhclient you're using is from that package.

Answer 2

Maybe your network requires you to use a proxy server?

Answer 3

To manually input a default gateway you would run this at the command line:

~$ route add -net default gw xxx.xxx.xxx.xxx

Though, like someone mentioned above, seems like you're having other problems. From what I can tell, it sounds like you're being routed through a proxy (configured by the school). Similar to what you'd see when you connect to a public wifi access point and you're redirected to a webpage to accept terms/agreements before you can move onto to surfing the web. Did firefox give you a specific error?
