[SOLVED] Finding UUID of a network card

Terminator3000 · 07-20-2013, 03:03 AM

Is there a command similar to ls -l /dev/disk/by-uuid or blkid

BUT specifically for finding the UUID of a newly installed network card ?

Background:

I am setting up two devices with Static IPs and channel bonding them into one, but I can't find the UUID of the new card.

I use Centos 6

Thanks

The mac address is unique - some of your hardware tools should pick that out. uuid is for disks.
That aside, the box will find one first - that's eth0. Next one is eth1 and that info should be in the logs. If they're both exactly the same cards, you'll have to dig for the mac address and try

ifconfig -a

and look for the HWaddress

You are right, no UUID for network cards, Thanks

This is an old thread, but I just wanted to ascertain we do have UUIDs for network cards, which can be found as below.

Code:

# uuidgen ifcfg-eth0
e62680c3-f5f5-4f06-b862-68e00e3b4506

Umm, no it is not, that is how you change the UUID, not how you find it.

I know it is an old thread, I add this for the reference since it is still hard to find this correct answer to the question in subject:
nmcli connection show

exactly, and you could grep it:

Code:

nmcli connection show eth0 |grep connection.uuid
