Debian Buster guide is online

After weeks of research, testing and writing the new guide for Debian Buster is finally online!

The famous ISP-style mail server tutorial lives here. Learn how to set up your own fully-functional mail server using Postfix, Dovecot IMAP/POP3 and MySQL backend on a Debian server just like your favorite mail or website hosting provider. This guide is a voluntary project with no profit in mind.  Go ahead and learn to run your own mail server.

My projects

I am a system administrator and programmer. In my nerdy spare time I work on web applications, Python and Ruby programs, write articles or explore new software technologies. On workaround.org you can find news, solutions and hints on my findings and get help. Of course your feedback is welcome.
These are some projects I am currently working on:

IRC – Internet relay chat

  • IRC is a great medium for getting instant help (at least on the freenode IRC network). I have collected some tips about Getting help on IRC to help you get help instead of getting barbecued.
  • knoba's factoids
    I run a bot called knoba (short for knowledge base) on the freenode IRC network. Two channels I visit frequently are #postfix and #squid. So I have fed the bot with lots of factoids that you can query using !foobar in the channel. These are the factoids understood in #squid and #postfix. Please don't play with the bot publicly. Send it a "/msg knoba help" and learn how it works.

Regarding the Squid web proxy

Squid is a powerful open-source web proxy. I was responsible for a large Squid installation at a former employer. Maybe the following articles help you save time in your daily work.

Padrino web framework

Padrino is an lean Ruby web framework. It is an interesting alternative to the heavier Ruby-on-Rails. I spent quite some time with it and created a couple of articles about it:

Zabbix monitoring

Zabbix is a mighty open-source monitoring software. If you need a serious system for your organisation and manage to condone its creepy web interface it is hands down the the most superior software I have ever seen. And I have been dealing with monitoring software since Nagios was called Netsaint.

These articles should help you in your daily work maintaining a monitoring system:
