32 Q: I'm using Redhat Linux (or some other RPM-based distribution).
33 Which packages should I install?
35 A: The package monitoring-plugins-<version>.<arch>.rpm contains only
36 those plugins that should work on any POSIX compliant system. In
37 other words, you should be able to install this package on your
38 system, no matter what else is or in not installed.
40 However, most of us have more complex systems than barebones
41 POSIX. We tried creating a variety of separate packages so
42 each dependency could be installed cleanly, but many people
43 found that this resulted in too many packages. So in the end,
44 all the non-POSIX plugins were folded into one RPM
45 (monitoring-plugins-<version>.<arch>.rpm). Most people will need to
46 use RPM's '--nodeps' option to install this package.
49 Q: My system uses the .deb package format. What packages should I
52 A: We strive for cooperation between all packagers and developers.

65 RPM using monitoring-custom.spec with 'rpm -ba'.

70 Warning: Return code of 127 for check of service 'PING' on host 'anyhost' was out of bounds.
72 when I run Nagios. (Often check_ping runs just fine on the
75 A: Commonly, system administrators will make security as tight as
76 possible on the monitoring system. Sometimes this includes OS
77 options or hardening scripts that prevent unprivileged users from
78 running the ping command. Nagios runs with no more privileges
79 than 'nobody' -- check to be sure that the nagios user can
80 actually run check ping. (This can also happen with other binaries
81 executed by nagios, but ping seems to be far and away the biggest
85 Q: I have a plugin to offer. What can I do?
