So that a group of plugins may use their own cache, and not all plugins try to work with linuxfabrik-plugin-cache.db at once.

In GitLab by @markuslf on Jul 21, 2021, 10:52

So that it we are able to check version('v3.0.7-2') < version('3.0.11')

The REGEXP operator is a special syntax for the regexp() user function. No regexp() user function is defined by default and so use of the REGEXP operator will normally result in an error message. If an application-defined SQL function named "regexp" is added at run-time, then the "X REGEXP Y" operator will be implemented as a call to "regexp(Y,X)".

import sqlite3
import re

def regexp(expr, item):
    reg = re.compile(expr)
    return reg.search(item) is not None

conn = sqlite3.connect(':memory:')
conn.create_function("REGEXP", 2, regexp)
cursor = conn.cursor()
cursor.execute('SELECT bar FROM foo WHERE bar REGEXP ?',['"test"'])

Add a parameter extended, default False (so that we can remove the unused function fetch_ext() (no more duplicated code)).

Instead of "2m 2w" print "2M 2D" to increase readability (2 months, 2 days), so that one does not confuse this with "2m 2s" (2 minutes, 2 seconds).

which is used in base, causing:

    in main() File "/usr/lib64/nagios/plugins/disk-io", line 138,

    in md5sum return hashlib.md5(string).hexdigest() ValueError: error:060800A3:digital envelope routines:EVP_DigestInit_ex:disabled for fips

redhat implemented a usedforsecurity=False parameter, which was also integrated into python >= 3.9 (see https://bugzilla.redhat.com/show_bug.cgi?id=1744670).

this could be implemented as a fallback. the other question is, how do we handle this if usedforsecurity is not available.

can be replicated on a system according to https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/security_guide/chap-federal_standards_and_regulations (the 'After the System Installation'-steps are enough).

Linuxfabrik Libraries for Icinga Check Plugins 2020052801

In GitLab by @markuslf on Jul 8, 2021, 16:58

snmp2 check is unable to use the function read_csv(). read_csv() contains Python 3 code, and checking for empty rows does not work as expected (unknown variable l)

Implement this interface:

def state_to_string(value, state, parenthesis=True, return_ok=False)

expected outputs

state_to_string(123, STATE_CRIT, parenthesis=True): '123 (CRIT)'
state_to_string(123, STATE_OK, parenthesis=True): '123'
state_to_string(123, STATE_OK, parenthesis=True, return_ok=True): '123 (OK)'

Consider being in git/linuxfabrik/lib and running pydoc -b (starting the webserver for surfing the documentation), most of the modules fail with pydoc.ErrorDuringImport: problem in net3 - ImportError: attempted relative import with no known parent package. Is there a way to get around this?

Some services send mails for example if an Access Token had to be updated, including the accessing user agent. Currently, the Linuxfabrik Monitoring-Plugins using lib.url are recognized as Library (Python-urllib/unknown) - Unknown location. Maybe it is possible to set something like Linuxfabrik Monitoring Plugin to better identify the client.

Mail from Metabase:

We've noticed a new login on your Metabase account.

Hi Metabase,

When using the fail2ban check on Ubuntu 20 and Ubuntu 16 servers after doing apt install fail2ban on each server I get the following error:
Problem while testing if the fail2ban server is alive. Status unknown.
Output of

lib.base.shell_exec(cmd + ' ping')" on line 73 is: 
"Permission denied to socket: /var/run/fail2ban/fail2ban.sock, (you must be root)".

As a workaround I did chown nagios:root /var/run/fail2ban/fail2ban.sock which worked.
Can this be resolved?
