[SOLVED] dhcpcd service not working

corona80 · Post by **corona80** » Tue Apr 19, 2022 6:30 pm

I have a new install with a strange dhcp issue. I must be missing some obvious setting, but it's eluded me.

Running rc-service dhcpcd start --verbose:

Code: Select all

...
start-stop-daemon: fopen '/var/run/dhcpcd/pid" No such file or directory
...
no valid interfaces found

But running "dhcpcd eno1" works perfectly.

Contents of /etc/config.d/net:

Code: Select all

net_eno1="dhcp"

Are you trying to start both the dhcpcd and net.eno1 services at the same time?

Please do not do this as they conflict and will fight over the interface.

Choose only one and disable the other one.

Plz try

Code: Select all

dmesg | grep eno
ip a

Is your iface clearly shown?
Is this a vm?

This was the problem. I mistakenly installed dhcpcd, thinking that was needed for dhcp.

Thanks for the help, and unreasonably fast replies.

You can install the package dhcpcd, but don't run 2 services that provide dhcp. netifrc (net.eno1 service here) will use dhcpcd if it exists on startup but do not start the dhcpcd service when using netifrc on the same interface.

Thanks for clarifying. I ended up removing the dhcpcd package. It was starting automatically, even after I removed it from the default runlevel. I did not look to see what was causing that. Perhaps it was another runlevel, or was getting pulled in as a dependency.

Honestly, I'm just coming back to Gentoo after a decade away, and the learning/relearning process is steep. And a lot of fun!
