Ubuntu OS connectivity issue with port 5666 in Nagios

If you have the NCPA Agent installed you would use the NCPA Wizard, not the Linux wizard.

Thank you. Seems it works now for the monitoring.


However, still not ping-able from nagios to ubuntu server. I already talked to our network team and they confirmed they allow the ports / configuration and there's no issue with the network or firewall.

Server is down in Nagios XI Monitoring


This is the current setting of our hosts file.

root@azisgezrxcpq01:/home/vmadmin# cat /etc/hosts
127.0.0.1 localhost

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

10.10.13.6 ntp1
10.10.13.33 ntp2

If you cannot ping from the nagios server on the command line to the IP of these servers if has to be either a network problem or something blocking ICMP like a firewall

Code: Select all

ping 10.10.20.11

This would not be within the Nagios software
