I've been head-scratching most of the afternoon over this. I've installed NRPE 2.7.1 on a Fedora Core 6 machine, and no matter what I try, it doesn't like the command_prefix setting.
Here is my config: ... ### Daemon Options pid_file=/var/run/nrpe.pid server_port=5666 #server_address=192.168.1.1 nrpe_user=nagios nrpe_group=localservice #allowed_hosts=127.0.0.1,82.165.38.62 dont_blame_nrpe=0 #command_prefix=/usr/bin/sudo debug=1 command_timeout=60 connection_timeout=300 #allow_weak_random_seed=1 ### Commands configuration ... with all the commands listed afterwards (check_dns, check_procs etc.) Notice how command_prefix is commented out. This works: # ./check_nrpe -H 127.0.0.1 -c check_dns DNS OK: 0.062 seconds response time. portland-1.andyshellam.eu returns 89.200.137.203|time=0.062236s;;;0.000000 If I uncomment command_prefix and kill/restart NRPE: # ./check_nrpe -H 127.0.0.1 -c check_dns NRPE: Unable to read output If I login as the Nagios user ("nagios") which is whom NRPE runs under, and try the command I believe NRPE is trying to run: $ /usr/bin/sudo /usr/local/nagios/libexec/check_dns -H portland-1.andyshellam.eu -a 89.200.137.203 DNS OK: 0.005 seconds response time. portland-1.andyshellam.eu returns 89.200.137.203|time=0.004811s;;;0.000000 Any ideas, anyone? I've tried with and without SSL - makes no difference, enabled debugging but don't get anything helpful in syslog. I have some plugins that need root privelege so need this working. Thanks, Andy. _________________________________________________________ DISCLAIMER This e-mail was sent through a Mail Network server.
