Is the address of the server changing? Perhaps a low DHCP lease time? Alternatively, are you sure the nrpe daemon is starting properly, and that your firewall is not being reset, or changing upon system start? Looks like it is just having routing issues to port 5666 on that address.

Dear,
Static IPs used rather then DHCP.
Firewall is disabled.
NRPE is running fine.
Anyother suggestions?

How long are you waiting after the system is brought down, and between checks? If you run "shutdown -h now" on the machine and test immediately after, you might get a timeout as the machine is still on but no services are running. Then the next check might be done after the machine really is down, showing the second error of no route.

What version of Nagios Core are you running?
Can you run this command on the Nagios Core server and post the output so we can get the version of the check_nrpe plugin?
Code: Select all
/usr/local/nagios/libexec/check_nrpe

Are these 2 boxes on the same subnet?
Can you add -vvv to your swap check?

Can you add the -vvv switch to the check as abrist suggested? We would like to see the verbose output.
