--- Begin Message ---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. -- System Information: Debian Release: 4.0 APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.18-4-vserver-k7 Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Versions of packages nagios-nrpe-plugin depends on: ii libc6 2.3.6.ds1-13 GNU C Library: Shared libraries ii libssl0.9.8 0.9.8c-4 SSL shared libraries Versions of packages nagios-nrpe-plugin recommends: pn nagios <none> (no description available) -- no debconf information

There was no feedback on our question for years and we can't reproduce the problem. I close this bug now, please reopen if you disagree. Thanks Alex
