[SOLVED] sshd.service won't wait for interface/netcfg at boot
Problem summary:
I have a home server that is configured with a static ip configured using netcfg and ifplugd. In the 'unit' section of sshd.service file I have 'After=sys-subsystem-net-devices-eno1.device' meant to let the service wait before the device is up. Ever since upgrading to systemd however at boot the sshd.service enters failed state. Only after manually issuing 'systemctl start sshd.service' the service will run and I can connect to it from another machine. I tried adding 'net-auto-wired.service' to the 'After' line but the result is the same.
/etc/conf.d/netcfg:
NETWORKS=(myethernet)

Re: [SOLVED] sshd.service won't wait for interface/netcfg at boot
I don't use netcfg and I don't have a static ip on my Arch box but I believe this is a known issue. Take a look at the bug reports for netcfg and/or search the forums. This issue (or very similar e.g. network failures as opposed to specific service failures) have definitely been discussed several times recently.

Does enabling the socket work? Sshd with systemd has socket activation, which is awesome.

Nice, this solves it indeed. thanks!
For anyone with the same problem it was just a matter of:
# systemctl disable sshd.service
# systemctl enable sshd.socketsee https://wiki.archlinux.org/index.php/Se … shd_daemon

I think netctl solves this problem
