Nagios Server not able to establish connection with VMS NRPE


Hello All,

We are trying to set up a linux box as a Nagios Server with a VMS NRPE client.

I am getting an “Connection Refused” message. Can someone help if I am missing something.

The server and the client are in the same network. There is no firewall setup.

Nagios Server :
Nagios version: 3.0
NRPE version: 2.8

VMS NRPE client :
NRPE version: 2.0
telnet enabled

telnet 5666
