Hello all

I have 2 cards on my system. I had no errors while Expert Install of Debian netinstall. even lspci shows me 2 ethernet controllers, However I cannot bring the 2nd interface up.

ifconfig eth1 tells me no such interface

ifconfig -a show me only eth0 and lo

Does lspci -v (or -vv) show what driver and kernel modules are in use
for that card ?

Show us the output of these two commands:

lspci -v | grep -i ether
dmesg | grep -i eth

Also, show us the content of your "/etc/network/interfaces" file.

Ahem... 'lspci | grep -i eth' is good but 'lspci -v' is paragraph
formatted and so finding that with grep is more trouble. You need a
"paragraph grep" of which there are many different programs and
techniques. Perl is always available these days so perhaps using perl
is easiest.

lspci -v | perl -00 -ne 'm/eth/i && print'

The extra -v information isn't usually useful though. YMMV.

Please also show us the output of

ip addr show

and also

cat /etc/udev/rules.d/70-persistent-net.rules

Hello guys,


Thanks alot. I sloved the problem. It was the older kernel which didnt have support for my Atheros Card. I did a modprobe and it fixed the problem

for the shake of completesness

lspci -v | grep -A5 -i eth

or the even easier
lspci -v | grep -5 -i eth

I commend your thoroughness. But...

But why did you stop at five lines? Aren't most network devices going
to print more lines than that? And it misses the "kernel driver in
use" line which is useful information.

Example:

Can't leave off the '-A' --after-context part since otherwise -NUM is
the same as --context not --after-context.

I see, in my case, 5 was enough to show everything

I said even easier, because the info you are looking for shows up the
same as with the qualifier, and you don’t have to remember witch is
witch (and less typing!)


that said, i have a bind grep='grep --color' witch i think is a must as
well


greets!

Nah, yours is too verbose for this matter ;-). Indeed, the extra information
(-v) can be omited as we just wanted to know what card it was.

In which case -nn is very useful.

Kind regards,
