Hi, the reason that the above commands fail is that there is no
systemd unit named neither 'approx' nor 'approx.service'.
systemd assumes '.service' for unit names that dont have any
type specified, see 'man 1 systemd'.

The name of the systemd unit is 'approx.socket'. So you need to use
that complete name all commands. If you put that complete name in
the above commands, then they will have a chance to succeed.

Examples:

[root@kablamm ~]# systemctl list-sockets | grep -E 'LISTEN|approx' -
LISTEN                            UNIT                            ACTIVATES
[::]:9999                         approx.socket                   -

[root@kablamm ~]# systemctl status approx.socket
