Listen on address instead of 0.0.0.0

General

Is there a way to configure the agent to listen on a specific address, instead of 0.0.0.0 ?

As far as I can tell, there are no options related to this in /usr/lib/systemd/system/cmk-agent-ctl-daemon.service file. /usr/bin/check_mk_agent --help is not really helpfull

The software that actually listens for incoming connections is the cmk-agent-ctl executable in daemon mode. (It’s not the checkmk agent itself.) cmk-agent-ctl can only be configured to listen on a different port instead of 6556 or allow incoming connections only from certain IPs instead of from all IPs. See cmk-agent-ctl daemon --help.

AFAIK there’s no possibility to locally bind to a certain network adapter or IP address.

I am afraid you’re right.

The -P option expects an integer, so specifying the address there won’t work either.

Thanks for the quick reply!
