How to install new nic in linux

[Red Squirrel]

I plugged in a USB nic in my system, it comes up when I type ifconfig but it's not in /etc/sysconfig/network-scripts/.

Do I just create the file? Or is there more to it then that? I recall having to run a bunch of commands with modprobe and such but I can't recall. Been a while.

Just copy one of the others and change the entries to match the new NICs name.

The initramfs scripts should start udev which will load the proper modules on bootup, you only need to mess with that stuff if it doesn't work.

Can't seem to get an IP off it. Is there a way to confirm linux even picked it up properly?

I'm setting up as a bridged network in vmware and no traffic seems to want to go on it.

If it's in ifconfig there's a module that claimed and registered it. If you assign an IP statically does it work?

Yep it works, just that DHCP is fubard I guess. Weirdly it's doing same in VMs. with TCPdump I can see DCHP disvoer requests but they get ignored. plugged a PC directly into the same router and got an IP fine.

I actually don't want this nic to have an IP as it's strictly a bridge nic but was trying to set one to test. But with static it works so at least I know linux picked it up. Now to figure out the VMware issue and I'll be set.

You can bring the interface up without an IP just fine.
