I recently created a new mysql backup script. It is compatible with local mysql-servers or can be used to backup the databases of a docker container. It will save on dump every hour and holds 6 of them normally and one every day, holding a complete week. I am running this script every hour via […]
I was recently introduced to a new software called Traefik. A reverse proxy / load balancer that’s easy, dynamic, automatic, fast, full-featured, open source, production proven, provides metrics, and integrates with every major cluster technology… No wonder it’s so popular! What else to say? Sounds exactly like a tool I would love. As my setup […]
I recently started to add some security features to my asterisk server. One was adding a fail2ban jail. Because I have asterisk running inside of docker, I mounted my log folder and changed fail2ban (installed on my docker host itself) to use the message file (in my case: /opt/asterisk/log/messages) .

Anyways some special cases are requiring you to login with one address, but send as another like WordPress on most php setups tries to. I created an account called firstname.lastname@example.org and changed some settings […]
Dieser Eintrag wurde nach der Erstveröffentlichung wesentlich erweitert und verändert. An dieser Stelle besten Dank an Sven Hofacker für das gemeinsame Erarbeiten einer besseren Konfiguration. Wenn man statt der weit verbreiteten Fritz!Boxen (und einigen anderen Routern) eine pfSense-Installation für die Bereitstellung des Internetzuganges nutzen will, sind einige Punkte zu beachten. DHCPv6 oder SLAAC oder 6rd? (WAN-Seite) Da bei IPv6 im Gegensatz zu IPv4 reichlich Adressen vorhanden sind, sind […]

Everytime your sass or js gets compiled or you simply changed one thing in your template, browsersync detects the file change and simply reloads your page. One nice extra is that css is […]
