AW: NRPE startup problems

[florian.beese at infoconsult.nu]

I had a look at the plugin, but I cannot find any error at it. It behaves
normaly!

When I call :  
/usr/lib/nagios/plugins/check_sensors.pl -s "temp1:55:65" -s "temp3:50:60"
The output is:
SENSORS OK - temp1 +36 C; temp3 +34.5 C| 'temp1'=36;55;65 'temp3'=34.5;50;60

When I call : 
/usr/lib/nagios/plugins/check_nrpe -H 127.0.0.1 -c check_sensors
The output is:
SENSORS OK - | 'temp1'=36;55;65 'temp3'=34.5;50;60

This also happens, when I use the network-card IP address instead of
localhost.

extract from my nrpe.cfg:
command[check_sensors]=/usr/lib/nagios/plugins/check_sensors.pl -s
"temp1:55:65" -s "temp3:50:60"

As said before, when I kill the nrpe process and start it again as a daemon
everything works fine. I don't have to do anything at the sensors or
anywhere else... I wonder why this cannot be a problem of NRPE?!

I really don't know what else I should have look at and what can be wrong
here. I also tried the rc-start script for SuSE Linux from the new CVS of
NRPE, but also with that init-script it didn't work at the start. Just after
a "restart" of the process.

Hope to get some ideas on this...

This can't possibly be an NRPE problem. You should look to the plugin 
instead or the nagios gui instead. NRPE just feeds back the first line 
of output it gets, and only cuts if it exceeds 1024 chars.
