CRITICAL - Socket timeout after 10 seconds

Post by tcpbr »

Hi.
We have dozens of windows virtual servers monitored via NSClient + +
Only in one server following this message appears with great frequency: CRITICAL - Socket timeout after 10 seconds
I've reinstalled the NSClient + + and apparently the server has no connectivity problem

How can we debug and solve this problem?

Best Regards

Tcp

How long has this windows system been up and running? There is a known bug with windows network stack if the system is up for an extended period of time. Other things you should start with, let's make sure the port is open first.

Code: Select all

nmap -p 5666,12489 [windows hostname\ip]

Both ports that you need open (12489 and 5666) are filtered...
5666/tcp filtered nrpe
12489/tcp filtered unknown
You will need to modify your firewall rules and open these ports.
