#!/bin/bash
# Podman check

Checkmk local script:

Read out data from an rrd file and show the values e.g. bandwith up- and downstream:

# /usr/lib/check_mk_agent/local

#!/bin/bash
# set -x

workdir='/opt/iperfmon'
#get data for altoo_office
downstream=$(/usr/bin/rrdtool lastupdate $workdir/iperfmon.rrd |tail -1|awk '{ print $2}')
upstream=$(/usr/bin/rrdtool lastupdate $workdir/iperfmon.rrd |tail -1|awk '{ print $3}')

echo "0 Iperfmon downstream=$downstream|upstream=$upstream Iperf up- and downstream: $upstream | $downstream (MBit/s)"

#echo "0 My service myvalue=73 My output text which may contain spaces"

Acme client- let’s encrypt

Issue new cert in opnsense UI

Wait for a long time until it’s issued with acme.sh client.

Certs on system

Find all certs in:

/var/etc/acme-client/

Linux

# Check disk free
# mki- 2023.05.09
count=$(df -h / |awk {'print $5'} |tail -1)
echo "P "Container-Filesystem" count=$count;80;90 Overlay-Filesystem"

Add-ons

deConz add-on

deConz -> config

Options:

use serial connection: /dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2651844-if00

NGINX Home Assistant SSL proxy add-on

no special config needed

but

upload cert and privkey file

-> that’s why you have to use the Terminal&SSH add-on

Geräte&Dienste / Integration

• Integration hinzufügen
• deConz
• Take ipaddress and port -> for that check API information in deConz Gateway (go by add-on)

Repo usage with username and password on github is deprecated.

Use Personal access tokens: https://github.com/settings/tokens

or: Github -> Settings -> Developer Settings -> Personal access tokens -> Tokens (classic)

To store the token (credential) for your machine:

git config --global credential.helper store
(store is example)

after that:

git push

Login with username and Token!

Opnsense cronjobs

Nice Web Tutorial: Custom Cronjobs mit OPNsense

Linux ssh key commands

Check a key

ssh-keygen -lf [key]

Scan a key

ssh-keyscan [host]

–> then do a scan ;-)
