Installing Ubuntu on IBM eserver, no network

c-- · 03-26-2005, 10:43 PM

I'm trying to install ubuntu warty warthog on an IBM eserver xSeries 300, and I can't get any network connection. I've checked my cables and tried using both ethernet ports, but it can't obtain an ip via dhcp. I know my router is working correctly because my ubuntu desktop works. The device and the switch show connectivity for the server. When I open the Computer > System Configuration > Networking gui, it shows my network device "Ethernet LAN card" and says its device eth0, but dosn't show eth1. When I try to click the "activate" checkbox, it checks it, and then it unchecks it (like the activate didn't work?) I'm so used to network devices "just working" under all the distros I've used I don't even know where to go for debug information on this. any help is greatly apreciated

Try from a command line:

Code:

# ifconfig eth0 up
# dhcpcd eth0

Ubuntu does a good job of hardware detection so the driver should be loaded...

dhcpcd : command not found
and I've got 2 ethernet devices, only one shows up, so it looks like it wasn't detected correctly.

Are they the same chipset? You need to figure out which physical device is getting detected. Usually dmesg will show which driver initialized which device (eth0 , eth1). If both nics are the same chipset it becomes difficult to tell which one is actually operational, because the kernel probes for only 1 card by default, and its the one that the kernel 'finds' first, which varies across reboots. You can tell the kernel which card to probe first however, using the kernel command line.

Also, some systems use 'dhclient' rather than 'dhcpcd'. See if that works...

tried both ports, neither works, dhclient dosn't work, just spits out a bunch of crap
