I've been struggling with this for the last 2 hours and I cannot work out where it's going wrong. I have a Nagios 2.7 server talking to an NRPE 2.6 client.
The Nagios 2.7 server is running FreeBSD as does the NRPE client - however the NRPE client is being run in a FreeBSD jail (this is a hosted system which I have no control of outside of the jail.) I'm hoping I've simply missed something simple. When I run from the console of the NRPE client, as the Nagios user: $ /usr/local/bin/sudo /usr/local/nagios/libexec/check_swap -w 25% -c 10% SWAP OK - 91% free (7442 MB out of 8192 MB) |swap=7442MB;2048;819;0;8192 $ When I run the check from the Nagios server: sudo -u nagios /usr/local/nagios/libexec/check_nrpe -H mackay.mailnetwork.co.uk -c check_swap NRPE: Unable to read output If I try an invalid command: sudo -u nagios /usr/local/nagios/libexec/check_nrpe -H mackay.mailnetwork.co.uk -c check_swapNOTEXIST NRPE: Command 'check_swapNOTEXIST' not defined So, as you can see, it is reaching NRPE fine (and I presume the SSL is working correctly.) I've tried starting up NRPE without SSL (-n), and ditto on the Nagios server - still the same error. I've also tried setting allow_weak_random_seed=1, same error. I'm guessing it has something to do with NRPE not sending the output data from the plugin to the correct stream, and as I don't know much about FreeBSD jails, I don't know whether stdin/out works as normal. As you can see, I've also set debug=1, but don't get anything in my log files other than "daemon starting up." Is anyone else running NRPE inside a jail? Or can point out something obvious I'm missing!? Or how to get more debug info? Thanks Andy. --- My nrpe.cfg file: pid_file=/var/run/nrpe.pid server_port=5666 #server_address=192.168.1.1 nrpe_user=nagios nrpe_group=localservice #allowed_hosts=127.0.0.1,10.100.9.201 dont_blame_nrpe=0 command_prefix=/usr/local/bin/sudo debug=1 command_timeout=60 connection_timeout=300 #allow_weak_random_seed=1 command[check_swap]=/usr/local/nagios/libexec/check_swap -w 25% -c 10% ------------------------------------------------------------------------- Take Surveys.
