[Ubuntu 8.04] Networking

[p858snake 1]

I've just set up ubuntu 8.04 desktop on my spare system. My netowrk doesn't seem to working and i'm new to linux so i don't know all that much about it and how to get everything working, all i know about the network card is thats PCI based and a few years old.

Edit:

Screenshot of the lspci -nn command (moved over onto my normal computer with a usb drive)

Edit2: ifconfig -a screenshot

Yup. I don't see an ethernet card in your lspci at all.

Can you open your computer and tell what kind it is? Or, better yet, throw in another card (even an old 3com lying around)?

The current one in the system which i can't tell what it is:

Front

back

i also have these lying around but i don't know if they actually work.

3COM Etherlink XL PCI

TPLink (Model: TF-3239DL)

That ethernet board uses a RealTek chip. The 8139 should be supported. Let's try to manually load in the module for it.

Open a terminal and then do:

sudo modprobe 8139too (load the second generation RealTek 8139 module into the kernel)

sudo ifconfig (list active interfaces)

sudo ifdown eth0 (shut down first ethernet interface)

sudo ifup eth0 (try to open first internet interface)

Those might get you going. If it doesn't seem to work, get another quick ifconfig and lspci in there to see if at least what Linux sees has changed.

Well i tried what you suggested and it didn't work so i got around to changing network card and the pci port it uses (just to be sure) and it seems to be picking it up now, just i need help getting it working

[markjensen 86]

Well, it is seeing your RealTek 8139 now. Is that what you have installed?

And the sudo ifup eth0 doesn't work? (although it may already *be* up, from what I see)

In this case, it may be a matter of getting an IP address. I assume that you set Ubuntu up for DHCP when you installed, not static IP? The "ifconfig" you posted shows no IP address assigned to your card.

In this case, then doing a sudo dhclient might (might!) work. I really haven't had to troubleshoot network issues, so I can't help much more than this.
