Nagios Port information

Hello,
I have nagios server and nrpe servers in the same subnet. Can they communicate with each other as they are in the same network? Or should I open port 5666 in all of nrpe servers?
Regards,
Siddarth Hegde

port 5666 needs to be open on all NRPE servers AND you needs to add the nagios servers IP address to the allowed_hosts field in the nrpe.cfg and restart nrpe

Yes the iptables rule would be something like this on the remote machines
Code: Select all
iptables -I INPUT -p tcp -s xxx.xxx.xxx.xxx --dport 5666 -j ACCEPT
