I think I already have that, I am having this configured
service health-check { # this is the default configuration using the simple PING->PONG # example health-check. executable = script -p /bin/health-check.sh inet_listener health-check { port = 5001 } } bash-5.0# /bin/health-check.sh HTTP/1.1 200 OK Connection: keep-alive OK -----Original Message----- Subject: Re: Health check curl example Your health check script should implement HTTP protocol. Then you can use passthrough mode and use cURL. The provided script does not speak HTTP.

From the commandline it works fine when I type a PING I get a PONG. But how do I do a curl to this 5001 port? Tried something like this: bash-5.0# curl http://localhost:5001/ curl: (56) Recv failure: Connection reset by peer bash-5.0# curl http://localhost:5001/PING curl: (56) Recv failure: Connection reset by peer [1] https://doc.dovecot.org/admin_manual/health_check/ --- Aki Tuomi
