+ [impact]
+
+ knockd doesn't correctly start at boot
+
+ [test case]
+
+ TBD
+
+ [regression potential]
+
+ any regression would likely cause knockd to fail to correctly start;
+ regressions after starting up are unlikely.
+
+ [scope]
+
+ this is needed in b/f/g/h
+
+ [other info]
+
+ note that this project seems essentially dead upstream, the last official
release was 2014:

+
+ [original description]
+
I would like to request a small fix in the systemd unit file
knockd.service. Please add the [Unit] line
Wants=network-online.target
Bug description:
When the system starts, the knockd daemon fails with a message "knockd[1012]:
could not open eno1: eno1: That device is not up". This bug was also described
here:
https://bugzilla.redhat.com/show_bug.cgi?id=1730634
In accordance with the recommendations in the systemd.unit
documentation, it should be sufficient to accompany the After= option
with a Wants= option.
This fixed the issue for me; and in the syslog I could see that the
network manager comes online before the knockd daemon (as required),
instead of after.
Tested on Linux Mint 20.1 that is based on Ubuntu focal (knockd
0.7-1ubuntu3).
