Hello fredie barron, welcome to LQ,

Code:
lspci | grep -i ethernet
(executed as root) should do the job.

i think -- ifconfig -a will do the job as well.

no, it will not since it shows only NICs which are up.

this laptop has an ethernet-adapter as well
Code:
samsung:~# lspci | grep -i ethernet
04:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8040 PCI-E Fast Ethernet Controller
samsung:~#
But please note that I'm not really sure if this depends on the distribution.

The OP wanted to see the network interfaces, not the (PCI) network devices. Admittedly both commands are useful though, in order to match devices <-> interfaces ;)

And 'ifconfig' shows all network interfaces - but only with the '-a' option.

Other than that, AFAIK both 'lspci' and 'ifconfig' commands are distribution-agnostics.

markhush,
it seems you did only ifconfig and not ifconfig -a. try ifconfig -a-- this will show all the NIC's.
In fact both the commands will work for this thread.

markush 03-31-2011 06:16 AM
Well :doh:,

I've to say sorry, you're both right, I didn't think about the "-a" option. Thanks for correcting me.
