Unable to connect to internet.


I'm brand new to linux, but not in any way new to computers. I do lots of web design, so have limited experience with the linux shell, and the file system. I was able to successfully get my Geforce 7800 gt card working with openSUSE by downloading and installing drivers. I tried to do the same with my Nvidia ethernet ports... but that hasn't worked yet. I am dual booting Windows XP Pro and openSUSE 10.2.

I am on a University campus network.

In windows, ipconfig /all reveals that I have DHCP enabled... so I enabled it in linux as well. I tried installing the forcedeth drivers, but that seemed to make no change, whereas installing the video card drivers immediately fixed everything in that departement. I really don't know how to check if the drivers installed correctly, and I can't seem to find any info online about it. The eth0 and eth1 ports both show up in Networks, but neither indicate being plugged in... and I am not sure which is which. Both are enabled. Both are onboard Nvidia ethernet ports on my mobo... work fine in Windows. But no matter how I change my settings (static ip, dhcp), it doesn't seem to work (aka i load firefox and get "page not found").

Anyone got any ideas? Pretty desperate to get this working. I hate doing web design in windows. I need KATE!

Thanks for the help.

It depends which ones you have... remote control troubleshooting always goes to the commandline, sorry but it beats second-guessing a gui.

Open a terminal and enter:

lspci

Hunt through the output for those lines talking about your ethernet controller. Copy them and paste them here.

Another thing to try in the terminal is

ifconfig

and

ifup eth0

We'll want to see the output of these commands too.

The drivers install properly if there are no errors. They are only used if they are needed, but, sometimes, you have to nudge them from the cli.

lsmod

... this tells you what drivers are being used. If you are positive the forcedeth drivers are what should be used, then we can deal with that next post.

MCP55 chipset (yours) uses the forcedeth drivers, yes.

ifconfig says that the nics are running, but no IP is assigned.
The ifup output confirms this, and that they are configured correctly for DHCP.
... presumably, this is not at the same time - attempting to access the university net through both nics simultaneously would need extra routing.

lsmod says that the forcedeth driver is loaded and running properly.


* check the little light is on (on the nic).
Code:
ifdown -a
ifup -v eth0 (with eth0 plugged in)

route

dmesg | grep eth0

The problem likely lies with the DHCP server connection. You'll probably have to take this to the unix sysadmin on campus...

great to hear that it's all set up right so far. Thanks for the help.

I do have them both configured for DHCP, but that is because I have no idea which one is which. They have the same name. Only one is plugged in to the wall, of course; but I don't know which it is!

I will run the code you posted. I'm booted in Windows right now (or I wouldn't be posting this), and the nic light is on. I'll check again when I switch over to linux.

Okay, I ran the commands, and when i did ifdown -a, it told me -a was not a valid argument.

ifup -v eth0 tole me that eth0 was not configured. sorry, i don't have a copy of the output, as i don't have a fat32 drive to save it to, i'd have to burn it to a cd >.< I also contacted our technology support desk, and they told me that it was something wrong with my configuration. Many people are apparently successfully running linux on our network.

I've been messing around with it even more, and on shutdown, when i press escape to see details, it says services that failed : network.

so i'm going to try a reinstall and let you know how that goes.
