| + | CHECK_NRPE: Error - Could not complete SSL handshake. | ||
| + | there are multiple reasons that can cause this error as this message is kind of generic error. | ||
| + | |||
| + | Typical problems: | ||
| + | * Server from you are accessing NRPE is not listed in ''allowed_hosts'' directive on NRPE server. | ||
| + | |||
| + | One of the tricky reasons that can cause this error is ''/etc/hosts.allow'' file. Even if you add server's IP in allowed_hosts, server cannot connect because this IP also needs to be listed in ''/etc/hosts.allow'' file by adding line: | ||
| + | nrpe: 10.10.10.10 monitoring-server.my-company.com | ||
| + | There is no need to restart nrpe server. | ||
| + | This is required as NRPE server on centos is compiled using ''tcp_wrappers'' library which parses this file. | ||
