Package: nagios-nrpe-plugin
Version: 2.5.1-3
Severity: important
When check_nrpe contacts a NRPE server who doesn't allow the IP address it exit
with return code 141.
It should normally return 3.
I've tried with the original source and it works, so there is a problem with
the patch but I can't find it.
Here is the test case with the check_nrpe provided by the package :
nagios:/# /usr/lib/nagios/plugins/check_nrpe -H 10.3.0.24 -c check_cpu
nagios:/# echo $?
141
The interesting part of the strace is the end :
write(3, "\27\3\1\0 \350\237Or{X\343\2521l\301\346\360\353\273\313"..., 1114) =
1114
read(3, 0x805d3b8, 5) = -1 ECONNRESET (Connection reset by
peer)
alarm(0) = 10
write(3, "\25\3\1\0 \326\17\341\2627\232,\240\304\363\30/\233\327"..., 37) = -1
EPIPE (Broken pipe)
This is a problem because Nagios considers this result as OK.
The NRPE server is a windows XP with NSClient++-20070306-1940 installed.
I've been able to reproduce this problem on a another machine just by removing
the IP address of the
Nagios server
Now the test case with the same source but with patch not applied :
nagios:~/nagios-nrpe-2.5.1/src# ./check_nrpe -H 10.3.0.24 -c check_cpu
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for
error messages.
superca-nagios:~/nrpe-2.7.1/src# echo $?
3
I have searched in the patch but I don't find any idea to correct this problem.
