Previously, when a process exited between the call to /bin/ps and
stat("/proc/his/exe") was exiting it was not considered as possible
instance of check_procs. This commit makes check_procs ignore all
processes where /proc/pid/exe does not exist.
Make check_procs filter out itself in the process list by comparing the
file pointed to by /proc/pid/exe. On platforms where this is not
available or when check_procs is passed the -T flag, the old behaviour
(check whether PID equals getpid()) is retained.
This fixes some false alarms when e.g. Nagios has, for whatever reasons,
some backlog of checks to run and check_procs with -a is called more
than once in a short time, matching its sister process.
This commit fixes sourceforge.net bug #3552839.
It adds a -k|--no-kthreads option to ignore kernel thread processes.
Please note: currently this feature only works for GNU/Linux systems (due to the fact I have no other systems to test/develop on)
Sorry for that, but I'm sure this can be accomplished by somebody else ;-)
Let check_fping use IPv6 only if
- the operating system supports IPv6,
- the user didn't specify --without-ipv6, and
- the "configure" script found the fping6(8) binary.

plugins/check_pgsql.c
multiple headers have to be set by multiple -k switches. Seperating them
by semicolons is not longer supported as semicolons are valid characters in
http headers.
The check_ntp_peer plugin now ignores response packets with an
unexpected "Operation Code" and/or "Sequence" number (cf. RFC 1305,
Appendix B). This fixes an issue where the check_ntp_peer requests got
duplicated on their way to the server (due to some network switch bug),
and the server therefore sent multiple responses per request.
Thanks to Marc Haber for reporting the issue.
This commit fixes sourceforge.net bug id 3571331.
The semicolon was defined as input delimiter for multiple values in the -k arguments.
Due to the fact the semicolon is a valid character for HTTP header fields this input delimiter function was removed.
It is still possible to pass multiple header fields via multiple -k (like described in helptext).
By using a more automake-style handling of dependencies and a single
convenience library, it's tremendously easy to build in parallel.
Note that since the linking happens with the static archives, the
unused objects are discarded and provide no overhead whatsoever.
The previous name would collide with popen's. Even if the two are
never used together, it's still a good idea not to have the same
symbol in multiple object files.
"./check_tcp -6 -p 80 host" leads to an error:
TCP CRITICAL - Invalid hostname, address or socket: 127.0.0.1
because 127.0.0.1 is the fallback host, the tailing hostname
was ignored.
Add command line options -4 and -6 (--use-ipv4 and
--use-ipv6) to check_dig.
Effectively this adds no new functionality, just a
shortcut for:
check_dig -A "-4"
check_dig -A "-6"
Needed for using check_dig with the check_v46 wrapper
(see e.g.
https://gitorious.org/nagios-monitoring-tools/nagios-monitoring-tools/blobs/master/check_v46)
which requires -4/-6 command line option support.
The memory allocation mixed up number of bytes with number of pointers,
meaning as soon as we'd reach (on 64 bit systems) the second argument,
we'd start writing it outside of our allocated memory.
Normally, this isn't too visible, but as soon as you (again, on my 64
bit system) reach argument number 8, you get a segfault. It is easily
reproducible with:
check_snmp -o '' -l '' -o '' -l '' -o '' -l '' -o '' -l '' \
-o '' -l '' -o '' -l '' -o '' -l '' -o '' -l ''
This patch allocates the proper amount of memory, to fix the issue.

Add command line options -4 and -6 (--use-ipv4 and
--use-ipv6) to check_fping. IPv4 is used by default,
maintaining backwards compatibility with older
check_fping versions. IPv6 support requires the
fping6 program.
The implementation is really just an imitation of
check_ping IPv6 support: Plugin command line option
-4/-6 designates whether to run fping/fping6.
Please note that especially the changes to
configure.in might be all wrong - I don't know
what's the proper autoconf way, patching
configure.in just seemed to work for me.
This adds support for @<range> and makes stuff a bit simpler by removing code
duplications.
Note: Previously, the compatibility code for 'check_procs <warn> <max>'
accepted something like 'check_procs -w 10:-1 -c 10:-1 20 50' as well
(treating it as if '-w 10:20 -c 10:50' was specified). This is no longer the
case ... additional arguments are only used as warn/crit thresholds in case
-w/-c is not specified at all.
Dying without a hint of what went wrong is just plain annoying. With
this patch we at least get a hint.
While at it, we fix the string offset so the output we're interested
in doesn't keep the equal sign that snmpget prints.
