Package: arpwatch Version: 2.1a15-5 Severity: normal Dear Maintainer,
I use arpwatch via systemd, but had to notice, that arpwatch tries to start up before the network interface is fully up (some spanning tree issue). This leads to arpwatch failing and not correctly starting up. Jan 8 10:13:15 sys-241 systemd[1]: Starting arpwatch service on interface eth0... Jan 8 10:13:15 sys-241 arpwatch: Could not get IPv4 address on eth0 for bogon detection Jan 8 10:13:15 sys-241 arpwatch: No subnets to watch configured; either use -a to process bogons or watch subnets explicitly using -n network/mask Jan 8 10:13:15 sys-241 systemd[1]: arpwatch@eth0.service: Control process exited, code=exited status=1 Jan 8 10:13:15 sys-241 systemd[1]: Failed to start arpwatch service on interface eth0. Jan 8 10:13:15 sys-241 systemd[1]: arpwatch@eth0.service: Unit entered failed state. Jan 8 10:13:15 sys-241 systemd[1]: arpwatch@eth0.service: Failed with result 'exit-code'. Jan 8 10:13:16 sys-241 systemd[1]: arpwatch@eth0.service: Service hold-off time over, scheduling restart. Jan 8 10:13:16 sys-241 systemd[1]: Stopped arpwatch service on interface eth0. Jan 8 10:13:16 sys-241 systemd[1]: Starting arpwatch service on interface eth0... Jan 8 10:13:16 sys-241 arpwatch: Could not get IPv4 address on eth0 for bogon detection I think that arpwatch should wait until the interface is up, so I created the following /etc/systemd/system/arpwatch@eth0.service.d/override.conf which fixes the issue for me: [Unit] After=network-online.target [Install] Wants=network-online.target Maybe it would be a good idea to add something like this to /lib/systemd/system/arpwatch@.service Greetings Roland
