2015-01-29make use of MSG_CONFIRM optionalSven Nierlein1-0/+5
since MSG_CONFIRM is a linux thing and only available on linux kernels >= 2.3.15, see send(2)
2014-12-02check_icmp: Cast size_t values for printf(3)Holger Weiss1-2/+5
Convert size_t values to unsigned long for printf(3) in order to maximize portability.
2014-11-28check_icmp: Fix a few type errorsHolger Weiss1-5/+5
2014-11-28Don't mix variable declarations and codeHolger Weiss1-15/+23
We still support pre-C99 compilers.
2014-11-28Use kernel reception time on ICMP packets to compute rtt.Matthieu Kermagoret1-7/+48
This commit uses the SO_TIMESTAMP feature of setsockopt to fetch kernel reception time of ICMP packets. This avoids invalid computations of rtt on machines with heavy load and/or heavy network traffic.
2014-07-06check_icmp/check_dhcp: disable check, if we are rootJan Wagner1-3/+0
As it is possible to use capabilities(7) on linux or solaris privileges for example, it is not necessary in all cases to have those binaries making use of setuid.
2014-01-21Capitalize "Monitoring Plugins"Holger Weiss1-1/+1
"Monitoring Plugins" is a name.
2014-01-20Capitalize "Monitoring" when it's the first wordHolger Weiss1-1/+1
2014-01-19Project rename initial commit.Monitoring Plugins Development Team1-4/+4
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.
2013-09-04check_icmp: Minor whitespace/indentation fixesHolger Weiss1-7/+6
2013-09-04check_icmp: Support "--help" and "--version"Holger Weiss1-0/+8
Let check_icmp provide "--help" and "--version" flags (in addition to "-h" and "-V"), just as the other plugins do.
2011-04-29check_host: Allocate a large-enough buffer for the host table.Sebastian Harl1-1/+1
When specifying a host-name on the command line, each of its IPs is added to the host table (and each one is pinged). So, the buffer has to be large enough to hold all of the respective host objects. (argc - 1) only fits hosts with a single IP. Thanks to Max Kosmach <max@tcen.ru> for reporting this in Debian bug #623702.
2010-04-22Add newline after "Usage:" in --helpThomas Guyot-Sionnest1-1/+1
2010-04-22Standardize the extra-opts notesThomas Guyot-Sionnest1-4/+0
2010-04-14Fix translations when extra-opts aren't enabledThomas Guyot-Sionnest1-4/+4
Bug #2832884 reported problem with translations outputting pot file headers. This is caused by "" matching the header of the translation files. This patch moves gettext macros inside utils macros and update some french translations.
2009-10-16Set proper network byte order for icmp_id and icmp_seq in icmp packetsThomas Guyot-Sionnest1-10/+11
2009-10-16Increment per-host sequence in check_icmpThomas Guyot-Sionnest1-11/+13
2009-06-14Fixed error in rtt/rta calculation in case of system clock problemsMatthias Eble1-1/+1
Time differences are now set to 0 in case of backward timejumps so there are no wrap-around problems any more. The RTA calculation hopefully gets a more accurate value in these cases also.
2009-06-01Don't use the plain char type for data buffersHolger Weiss1-6/+6
Buffers which are used for holding arbitrary data should be referenced using pointers to void and accessed using pointers to unsigned char. Signed-off-by: Holger Weiss <holger@zedat.fu-berlin.de>
2009-06-01Fixed check_icmp compiler warnings by including float.hMatthias Eble1-0/+1
Self defined DBL_MAX caused compiler warnings. Now float.h which defines DBL_MAX is included.
2009-06-01Fixed --help output for warn and critical thresholds (sf.net #2796624, ↵Matthias Eble1-2/+2
debian #530553) check_icmp wrongly calculated the current thresholds in --help output.
