Package: openvpn Version: 2.4.0-6+deb9u2 when booting the system, systemctl shows openvpn as failed. in the openvpn logs I find:
TCP/UDP: Socket bind failed on local address [AF_INET]192.168.90.1:1194: Cannot assign requested address but in /etc/network/interfaces I have: auto jacktrunk.13 iface jacktrunk.13 inet static address 192.168.90.1 netmask 255.255.255.0 when restarting openvpn via sysctl restart, everything works fine. So the network interface is not yet up when openvpn tries to bind to it. As a workaround I patched: /lib/systemd/system# diff -u openvpn\@.service~ openvpn\@.service --- openvpn@.service~ 2017-07-18 22:15:17.000000000 +0200 +++ openvpn@.service 2018-04-11 17:39:37.759664731 +0200 @@ -20,6 +20,9 @@ LimitNPROC=10 DeviceAllow=/dev/null rw DeviceAllow=/dev/net/tun rw +Restart=on-failure +RestartSec=10 [Install] WantedBy=multi-user.target Now when rebooting everything works. Checking the logs I find, that the first try fails as above, and then 10 seconds later the startup is retried and everything works fine. I know this is a hack. But maybe it is not possible to arrange systemd to to the correct ordering in all use cases and a retry every 10 seconds could be a more robust solution. Dunno. Best Regards Erik
