Because there seem to be so many different fashions (70-persistent-net.rules, udev, HWADDR) in how Linux in general and Rocky Linux 8 and 9 do things, here's a way to things for a server that has several NICs | |||
* Pick a NIC port, assign an 'outlandish' (IE, you're not going to use it in the future) IP Address to it, make sure it works and then WHACK all the other ethernet devices / interfaces , using Webmin (handy if there are a bunch of NICs) or via command line. | |||
* Rename Interfaces if desired (AKA getting rid of the freaky Rocky8 Network Interface names), see below example where enp2s0 is renamed to eth0; | |||
** <code>ifdown enp2s0</code> | |||
**<code>ip link set enp2s0 name eth0</code> | |||
**<code>mv /etc/sysconfig/network-scripts/ifcfg-enp2s0 /etc/sysconfig/network-scripts/ifcfg-eth0/</code> | |||
**<code>nano /etc/sysconfig/network-scripts/ifcfg-eth0: DEVICE=eth0 (NAME Directive too if present)</code> | |||
**above is from: https://tekneed.com/how-to-rename-nic-in-linux-centos-rhel-7-8/ | |||
**...and check with above noted "Hardware Commands": lshw -class network -short | |||
