Server not running (systemd)
After configuring the server (file /etc/openvpn/server.conf, the server does not start:
service openvpn start # or systemctl start openvpn
service openvpn status # show active (exited)
ps faux | grep openvpn # no service running
ss -tupan | grep 1194 # idem
service openvpn stop
We have to tell systemd to create new generators [2]:
systemctl daemon-reload
service openvpn start
ps faux | grep openvpn
# nobody 28798 0.0 0.0 30676 3016 ? Ss 11:46 0:00 /usr/sbin/openvpn ...
ss -tupan | grep 1194
# udp UNCONN 0 0 *:1194 *:* users:(("openvpn",pid=28798,fd=6))
More info on openvpn in systemd. For instance, to start a specific configuration:
systemctl enable openvpn@sample.service
# creates a symlink in /etc/systemd/system/multi-user.target.wants/openvpn@sample.service
# pointing to /lib/systemd/system/openvpn@.service
