Posted: Tue Jul 05, 2022 10:53 pm Post subject: [Solved]Network interface name issue.

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

Code:

Here's output of

Code:

❯ dmesg | rg r8169

before I run

Code:

doas ip link set dev eth0 name enp8s0

I than get

Code:

After I run that dhcpcd is working correctly. Here's output from kern.log

Code:

And here's daemon.log

24 Jul 5 16:19:31 soydfree dhcpcd[1581]: no interfaces have a carrier

Hopefully I've provided enough relevant information.

Hi
What is the output of

Code:

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

Here's

Code:

❯ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether a8:a1:59:16:66:a6 brd ff:ff:ff:ff:ff:ff
3: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1000
link/sit 0.0.0.0 brd 0.0.0.0

and

Code:

❯ doas emerge -p systemd-utils

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild R ] sys-apps/systemd-utils [251.2-r1] USE="kmod (split-usr) tmpfiles udev -acl -boot (-selinux) -sysusers -test" ABI_X86="(64) -32 (-x32)" 0 KiB

Total: 1 package (1 reinstall), Size of downloads: 0 KiB

I don't use grub just efistub with efibootmgr.

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.

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...

Georgi
