Hi Patrick
Nothing telling in the logs as far as I can see.
On the Nagios server:
> Aug 28 14:32:36 dns nagios: SERVICE ALERT: Sydney-1;Disk Space on
> /endeavour;UNKNOWN;HARD;1;Cannot map "tcp" to protocol number
That's the only line for that time and date.
On the client, absolutely nothing since the NRPE daemon was started:
Aug 27 10:23:40 sydney-1 nrpe[2505]: Starting up daemon
Aug 27 10:23:40 sydney-1 nrpe[2505]: Listening for connections on port 5666
Aug 27 10:23:40 sydney-1 nrpe[2505]: Allowing connections from:
127.0.0.1,84.18.200.160
One thing I had noticed is there were 8 services that were checked at
that exact time. Don't know if this could be a factor in it or not.
I'm in the process of setting up a Nagios 2.5 server - I'm going to use
exactly the same configuration files and plugins, stop the 2.4 server
and let the 2.5 server run for a couple of days. If I don't get any of
these errors then I'll know it's a server issue.
THanks
Andy.
