When enabling knockd with systemctl y get the following error:
###
$ sudo systemctl enable knockd
Synchronizing state of knockd.service with SysV service script with
/lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable knockd
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias
settings in the [Install] section, and DefaultInstance for template units).
This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
4) In case of template units, the unit is meant to be enabled with some
instance name specified.
###
It doesnt start at boot also.
If I add the following to the end of /lib/systemd/system/knockd.service then I
can enable it successfully and starts at boot:
###
[Install]
WantedBy=multi-user.target
Alias=sshd.service
