Maybe I haven't explained exactly what I mean: I want to somehow find out the relation between loaded kernel-module and ethernet-devicefile. Without physical access ... In another way: "Which kernel-module is in use for /dev/ethX ?" For example I have Intel-Servers with two Intel-NICs, one needs e1000, the other e1000e. If that server is 100 kms away I 'd like to be able to ask the system "does eth0 run on e1000 or e1000e?". For udev the trick with grepping the rules-file is somehow nice. I assume there would also some other way to ask udevd itself? dmesg as well, although I think there should be a way to find that connection even when I did a "dmesg -c" somehow. "lspci -v" tells me about the loaded module for the pci-device, fine. But even with "-vvv" I don't see the link over to the MAC or something like that. Thank you all, Stefan

Repeat with the other interfaces. Also look at ethtool -p (details in the man page).

Re: [gentoo-user] which NIC is which?
I usually do one of two things. Depending on the situation. If both NICs are from the same vendor I install mii-tool and only plug in one port. mii-tool will show link state. This when it negotiates it will show output like: eth0: negotiated 1000baseT-FD flow-control, link ok eth1: no link If the NICs are from different vendors I usally just do a ifconfig and grab the MAC addresses of the cards. Then I Google for a mac lookup tool. The first 6 digits of a MAC are vendor specific. Hope this helps! Colt On Fri, Nov 12, 2010 at 7:51 AM, Stefan G.
