2019-05-24fix maxfd being zeroGravatar Sven Nierlein
If _SC_OPEN_MAX is available then maxfd was zero initialized and never set to the value from sysconf. This leads to segfaults with free(): invalid size introduced by commit 7cafb0e84550035fe671662c293122be975065ca. Signed-off-by: Sven Nierlein <sven@nierlein.de>
2019-02-15check_by_ssh: fix child process leak on timeoutsGravatar Sven Nierlein
When check_by_ssh runs into a timeout it simply exits keeping all child processes running. Simply adopting the kill loop from runcmd_timeout_alarm_handler() fixes this. Signed-off-by: Sven Nierlein <sven@nierlein.de>
2016-11-07check_users not correctly detecting thresholdsGravatar John C. Frickson
Fix for issue https://github.com/nagios-plugins/nagios-plugins/issues/81 check_users now uses the standard warning and critical ranges parser and a standard perdata output routine.

2014-01-19Project rename initial commit.Gravatar Monitoring Plugins Development Team
This is an initial take at renaming the project to Monitoring Plugins. It's not expected to be fully complete, and it is expected to break things (The perl module for instance). More testing will be required before this goes mainline.

2003-03-15Spent the day working on backwards compatability using getaddrinfo()Gravatar Jeremy T. Bouse
Moved getaddrinfo.? and gethostbyname.? from lib/ to plugins/ due to problems with compiling into the libnagiosplug.a as it required linking against socket libraries which are unneeded except for network based plugins. This code should hopefully happily work for all systems and has been tested prior to commit on Debian GNU/Linux, SPARC Solaris 7 and SPARC Solaris 9. git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@424 f882894a-f735-0410-b71e-b25c423dba1c
