[Solved]Network interface name issue.

JustCauseWhyNot · Post by **JustCauseWhyNot** » Tue Jul 05, 2022 10:53 pm

Solved: The issue seems to be with sys-apps/systemd-utils:251.2-r1. I figured this out by masking it, and emerging sys-apps/systemd-utils:250.
I'm having issue where dhcpcd can't find valid interface. I did have my ethernet port named enp8s0, and that was working up until today. Now it's defauilting to eth0:, but I'm not sure why. Output of emerge.log that includes relevant packages emerged today

Hi
What is the output of

Code: Select all

grep -i cmdline /etc/default/grub
and
ip a #before you do any manual renaming
and
ls /etc/udev/rules.d
and 
emerge -pv  sys-apps/systemd-utils

Solved: The issue seems to be with sys-apps/systemd-utils:251.2-r1. I figured this out by masking it, and emerging sys-apps/systemd-utils:250.

Not sure.
I have the above version and there is no renaming happening.
Granted i have net.ifnames=0 kernel parameter applied.

I'm not sure if I made it understood but I want udev predictable interface naming. So my interface being named eht0 was a issue, and I wanted it named enp8s0. But I don't no why 251 is causing issues compared too 250.

Same issue here when systemd-utils package got upgraded from version 250.7 to 251.3. Not sure why, but all interfaces became ethX instead of the previous predictive names. Going back to ethX caused a lot of trouble on this system.

This is an openrc system and I used to have an INSTALL_MASK like this:
INSTALL_MASK="/etc/system.d /lib/systemd /lib64/systemd /usr/lib/systemd /usr/lib64/systemd <some non systemd related dirs>"

But also, just reverting to 250.7 fixed the problem and got me going. JustCauseWhyNot, were you able to get to the bottom of this issue? I have another system which is also openrc and has 251.3 on and it does use predictive names of the network interfaces just fine.

Isn't this the issue with iwd doing it'd own thing? Do you have iwd emerged?

This has no relation to iwd, I am afraid, see:

Did you check if you have iwd running?

Because I have no such issue and I have disabled iwd. In the same time I'm already on systemd-251.3.

Check it please.

The only odd thing is systemd reaches network target before the rename happens, but I'm not using the wired ethernet adapter...
