See attachedscottwilkerson wrote:It does.
Looking back at the original message it appears that something may be wrong with the plugin on the 5.5.1 server
Can you upload the file /usr/local/nagios/libexec/check_nagiosxiserver.php from that server so we can see if we can replicate the issue?

Your session has timed out.[[email protected]]# Note that this works the other way around....I am able to monitor the 5.5.1 server from the 5.5.2 server. I tried your command on the 5,5,2 server against the 5.5.1 server (the one that works) and the response is identical....scottwilkerson wrote:Can you get page results with a simple curl on port 80 from the 5.5.1 server?
