i've been trying to monitor our ticketing system using nagios, however i keep on having trouble connecting to its NRPE port 5666.When i try telnet, Connection was automatically closed by foreign host. Do you have any ideas what's causing this?.
[root ~]# telnet xxx.xx.xxx.xx 5666
Trying xxx.xx.xxx.xx...
Connected to xxx.xx.xxx.xx.
Escape character is '^]'.
Connection closed by foreign host.
As per checking, nrpe is already installed on the machine i'm trying to monitor.I'm also getting an error checking its NRPE
[root libexec]# ./check_nrpe -H xxx.xx.xxx.xx
CHECK_NRPE: Error - Could not complete SSL handshake.
