Generally, just running this as a socket activated unit should show the problem I guess. FTR, here are the involved unit files: /etc/systemd/system/check_mk@.service # systemd service definition file [Unit] Description=Check_MK [Service] ExecStart=/usr/bin/check_mk_agent KillMode=process User=root Group=root StandardInput=socket /etc/systemd/system/check_mk.socket: # systemd socket definition file [Unit] Description=Check_MK Agent Socket [Socket] ListenStream=6556 Accept=true [Install] WantedBy=sockets.target Michael, if you catch me on IRC (and are interested), I have a machine showing this problem that you could inspect...
