Hi,
the check-mk-agent is running (in xinetd mode) - trying to register a client is not possible because the cmk controller is looking for a socket (systemd)
[root@jumphost]# cmk-agent-ctl status
Version: 2.1.0
Agent socket: inoperational (!!)
IP allowlist: any
Legacy mode: enabled
No connections
[root@jumphost]# ss -tulpn | grep 6556
tcp LISTEN 0 64 [::]:6556 [::]:* users:((“xinetd”,pid=932,fd=5))
[root@jumphost xinetd.d]#
[root@jumphost]# cmk-agent-ctl register --hostname myclient \
--server cmkserver --site mysite \
ERROR [cmk_agent_ctl] Something seems wrong with the agent socket (/run/check-mk-agent.socket), aborting
[root@jumphost xinetd.d]#
