2024-03-26check_ssh: patches from op5 (#1738)Lorenz Kästle2-76/+234
* check_ssh: properly parse a delayed version control string This resolves an issue with SSH servers which do not respond with their version control string as the first thing in the SSH protocol version exchange phase after connection establishment. This patch also makes sure that we disregard a potential comment in the version exchange string to avoid nonsense mismatches. In the future, we might want to add the capability to match against a user specified comment. In addition, the patch largely improves the communication towards the server, which adds better protocol adherence. Of course, new test cases are added to support the trigger and guard against regressions of the bugs solved by this patch. This fixes op5#7945 (https://bugs.op5.com/view.php?id=7945) Signed-off-by: Anton Lofgren <alofgren@op5.com> * check_ssh.t: Fix a few typos Signed-off-by: Anton Lofgren <alofgren@op5.com> * check_ssh: Handle non-alpha software versions This patch fixes a bug where we would reject version control strings that do not contain letters, because the assumption is made that they always do. This is not required by the RFC however, and there exist implementations that do not contain letters. I've also added a few references to the RFC to make the process of parsing the control string more apparent. This fixes op5#8716 (https://bugs.op5.com/view.php?id=8716) Signed-off-by: Anton Lofgren <alofgren@op5.com> * check_ssh: Fix a typo in "remote-protocol parameter remote-protcol -> remote-protocol Signed-off-by: Anton Lofgren <alofgren@op5.com> * Remove unused variable * Formating fixes * Update translations * Remove merge conflict artefact from previous merge * Set fixed include paths * Improve code style to be slightly more readable * Update test cases for different netcat behaviour and reduce sleep time --------- Signed-off-by: Anton Lofgren <alofgren@op5.com> Co-authored-by: Anton Lofgren <alofgren@op5.com>

2024-03-23check_nwstat: adds percentage used space (#1183)waja2-0/+54
* check_nwstat: adds percentage used space This adds the new VPU parameter to the check_nwstat plugin. This parameter returns the percentage used space on a Netware volume. Now you can monitor your Netware volumes easy. We use it with a warning 85% and critical 90%. eg: check_nwstat -H your.netware.host -v VPUvol1 -c 85 -w 90 returns 324653 MB (95%) used on volume vol1 - total 340212 MB|Used space in percent on vol1=95;90;80;0;100. * check_nwstat: Fixing whitespaces and tabs * Update translation files * check_nwstat: Use C99 booleans also with the patch * Some formatting --------- Co-authored-by: RincewindsHat <12514511+RincewindsHat@users.noreply.github.com>
2024-03-18check_ircd: IPv6 support (#1995)alvar1-35/+26
The prior bindRemote function was restricted to IPv4 by explicitly using address family specific functions as pack_sockaddr_in or unparametrized gethostbyname. Since Perl 5.14, released in early 2013, there is IO::Socket::IP, which supports lookups and connects for a dual stacked network. By switching the connection establishment code, the plugin is now able to establish connections to IPv6-only hosts. Furthermore, additional -4 and -6 flags were introduced to enforce a specific address family. > $ netstat -p tcp -ln | grep 6667 > tcp6 0 0 *.6667 *.* LISTEN > $ ./plugins-scripts/check_ircd -H localhost > IRCD ok - Current Local Users: 4 > $ ./plugins-scripts/check_ircd -H localhost -4 > IRCD UNKNOWN: Could not start socket (Connection refused) > $ ./plugins-scripts/check_ircd -H localhost -6 > IRCD ok - Current Local Users: 4

2024-02-23check_disk increase alert precision (#1989)Sven Nierlein2-23/+7
* check_disk increase alert precision Free disk percentage value was rounded to a full integer meaning it alerted about ~1% percent too early. This is about 10GB on a 1TB disk.

On systems with higher core counts check_procs will occasionally see its own "ps" child process with a high CPU percentage and raise a false alarm. Ignoring the child processes of check_procs prevents this from happening.

2023-11-27check_disk: fix ignore-missing in combination with includes (fixes #1963)refs/pull/1967/headSven Nierlein2-18/+33
Using --ignore-missing together with regex matching and ignore option lead to a wrong error message. ./check_disk -n -w 10% -c 5% -W 10% -r /dummy -i /dummy2 DISK UNKNOWN: Paths need to be selected before using -i/-I. Use -A to select all paths explicitly The use case here is a cluster with fail-over mounts. So it is a valid situation that the regex match does not find anything in addtition with a ignore which also does not exist. After this patch: ./check_disk -n -w 10% -c 5% -W 10% -r /dummy -i /dummy2 DISK OK - No disks were found for provided parameters|
