I'm learning a little bit of nagios and unix(buster), and im getting an error related with monitoring CPU LOAD and MEMORY USAGE
The feedback I get from the monitor is
connect to address 192.168.1.94 and port 12489: Connection refused
could not fetch information from server
So I went to the client machine and ran netstat -an, and the port doesnt seem to be listening.
I tried to add some rules on iptables, did some rules for port 12489 on TCP
the port was there on "ACCEPT tcp -- anywhere anywhere tcp dpt:12489"
what am I missing? the machines are in the same local network
am im missing some configuration or plugin?
