2023-09-23remove root checkDanijel Tasov1-3/+0
We can perfectly do icmp without root by using capabalities. So, instead of doing unsufficient checks beforehand, we just try and fail if it doesn't work. Signed-off-by: Danijel Tasov <m@rbfh.de>

2023-02-19check_icmp: Fix compiler warningRincewindsHat1-1/+1
This fixes a compiler warning which complains about an uninitialized value for a variable which is then returned. This had no real world impact, since the program would crash in the branch where result is not set. The variable is initialized to "-1" which would be the error for inet_pton.
2023-02-19check_icmp: Fix compiler warningRincewindsHat1-2/+3
This fixes a compiler warning with no real world impact. The compiler complains about a missing return, which is correct, but in that scenario the program would crash anyways, so this has no impact.

2022-11-29check_icmp: fix parsing help/version long optionsAksel Sjögren1-8/+8
Fix parsing of the long options --help and --version. The special handling must be done before calling getopt(). This fixes erroneous output like: ./check_icmp --version ./check_icmp: invalid option -- '-' ./check_icmp: invalid option -- 'e' ./check_icmp: invalid option -- 'r' ./check_icmp: invalid option -- '-' ./check_icmp: invalid option -- 'e' ./check_icmp: invalid option -- 'r' Signed-off-by: Aksel Sjögren <asjogren@itrsgroup.com>

2021-11-15check_icmp: Fix pkt perfdata in check_host modeAksel Sjögren1-1/+1
Add missing "warn" threshold field in "pkt" perfdata output. Perfdata should be interpreted as; 'label'=value[UOM];[warn];[crit];[min];[max] With one field missing, the hardcoded min value '0' ended up in the "crit" field, making applications interpreting the perfdata thining that critical threshold is always exceeded.

2021-04-30Fix check_dhcp testsAksel Sjögren1-2/+7
* try to use "/usr/sbin/ip" before "ifconfig" since the latter is obsolete on Linux to figure out interface to listen for DHCP messages. But keeping ifconfig method just in case. Without this, tests fail on boxes without ifconfig AND the correct interface named ethX. * amend possible failure responses, as check_dhcp might get a DHCPOFFER, but from an unexpected address - which happens if the box running tests are on a network with a DHCP server.

2020-12-19docs: fix simple typo, conspicuosly -> conspicuouslyTim Gates1-1/+1
There is a small typo in plugins-root/check_icmp.c. Should read `conspicuously` rather than `conspicuosly`.

2018-12-10check_icmp: Do not overwrite -4,-6 on lookupJacob Hansen1-2/+10
In case we needed to do a lookup, we previously overwrote the address_family to IPv6, even if we supplied -4 as a cmd line argument. This commit should ensure the cmd line argument is always followed. Signed-off-by: Jacob Hansen <jhansen@op5.com>
2018-12-10check_icmp: emit error if multiple protocol versionJacob Hansen1-0/+4
As we do not support checking both IPv4 and IPv6 hosts in one execution we emit an error if multiple protocol versions are defined in the cmd line args. Signed-off-by: Jacob Hansen <jhansen@op5.com>

2018-12-07check_icmp: Correctly set address_family on lookupJacob Hansen1-1/+2
If a hostname is supplied instead of an IP address, the automatic address family detection would fail to correctly set the IP protocol version (it would always be IPv6). We now supply AF_UNSPEC to getaddrinfo, which should then return the correct address family in the result. Signed-off-by: Jacob Hansen <jhansen@op5.com>

2018-12-07check_icmp: process protocol version args firstJacob Hansen1-10/+22
Detection of protocol version is in the previous patch implemented in the add_target() function, which is called when adding the -H command line argument. That means that if a protocal version argument (-4, -6) is added after the -H then the protocol version might be incorrectly set. This patch ensures that we first process the protocol version arguments, and then we process the rest of the arguments. Signed-off-by: Jacob Hansen <jhansen@op5.com>

2018-12-07check_icmp: Add IPv6 supportLars Michelsen1-161/+330
This commit adds IPv6 capabilities to check_icmp. It is now possible to specify the address family using the arguments -4 (default) or -6. To make the change possible we had to move the argument parsing previous to creating the socket to be able to create it with the correct address family. This commit also fixes some gcc 4.9.2 compiler warnings. It has been tested with several current linux distributions (debian, ubuntu, rh, sles). This commit fixes monitoring-plugins/monitoring-plugins#1291

Don't just use the current time(2) to seed the PRNG that generates the xid. A DHCP server might be checked multiple times per second.
2016-09-14check_dhcp: Don't peek before reading responseHolger Weiss1-7/+1
Omit a recvfrom(3) call which has the MSG_PEEK flag set and should have no effect at all. According to a comment in the code, this call was meant to be a workaround to an opaque issue. If anyone runs into that issue, we should fix it properly instead.

2015-10-05Fix for unclosed filehandle in pst3 on Solarisabrist1-1/+3
On Solaris, check_procs uses pst3 instead of /bin/ps (see http://monitoring-plugins.org/doc/faq/ps-on-solaris.html for background). There's a small bug in pst3 which causes it to NOT report some processes that are at the end of the process table, at least on very busy systems (we noticed this on a CoolThreads T5240 with load averages up to 90). The bug is that a filehandle is not properly closed. Thanks to jwinkle01 for finding and patching the bug. (Closes #1203)

2015-10-02check_dhcp: Fix option parsingHolger Weiss1-31/+12
The call_getopt() function didn't always return the correct number of processed arguments. However, since check_dhcp doesn't support non-option arguments, the caller doesn't need this number anyway. Closes #1345.
