Howto set up a backup MX for Zimbra in Ubuntu/Debian

Have you ever wanted to set up a backup mail exchanger (MX) for your main Zimbra installation? Recently, I had this need for two of my Zimbra installations. Of course, if you run the enterprise version of Zimbra where they offer you the tools to do this without too much work out of the box. But if you just don’t have the resources to put up another full scale Zimbra server, you can achieve much of the same with much less. Of course, it won’t offer you all the bells and whistles that a full Zimbra installation will, but it does the trick if your needs are sparse. (more…)

Howto install Redmine on Ubuntu 10.04 LTS

Preface

What is redmine? Redmine is a flexible project management web application. Written using the Ruby on Rails framework, it is cross-platform and cross-database. What does that really mean though? What it means is that it gives you a great tool to manage your coding projects, either if you’re working solo or working in groups of people doing work on the same project. What’s great about redmine is all the nice little features it offers you, that makes managing your projects so much easier, some of them being

  • Multiple projects support
  • Flexible role based access control
  • Flexible issue tracking system
  • Feeds & email notifications
  • Per project wiki
  • Per project forums
  • SCM integration (SVN, CVS, Git, Mercurial, Bazaar and Darcs)
  • Issue creation via email

Having a tool that gives you all this makes it easy to follow what you’ve done on a project so far, what issues that have been uncovered with the code so far, and what has been done to fix these problems. But not only that, it also gives you a great tool to write online documentation for your projects, and have user driven forums for them at the same making the integration between you as a coder and the end users even more tighter. As an added bonus, as with any community as it grows the community starts helping itself, making you able to focus on what’s important and that’s improving your code. Its ties to most modern VCS systems, such as Git, Subversion and Bazaar also makes you able to track code changes in real time through the web, much like you do on Github and similar services.

XmasB quotes and BOFH fortunes for WordPress

This is one of those posts that I know will have a very limited audience. To the left, you see a block with random BOFH quotes, which I find rather amusing. I’ve always found them entertaining, and thought that they would make a nice addition to my blog as sheer entertainment for you guys. A while back, I found this great little plugin called XmasB quotes, that adds a widget to WordPress where it displays random quotes. The actual quotes are stored in the same MySQL database as WordPress. But then comes the issue that I faced. There are well over 400 of those quotes, and manually copy and pasting all those quotes into the admin interface of XmasB was not an option that seemed tempting. Not one bit. Now how could I solve that?

I love the open source community

As many of you know, I’m a true Debian fanatic. Some even say I’m a Debian nut head, borderline evangelist. And mark my words, to call me an evangelist is something truly unique, seeing how my feelings are towards true evangelists. But it has to be said, that I without a shadow of a doubt love and cherish the open source community. Many of us have heard the term open source, both in the media and in our travels across the world wide web. But what is open source, and even more importantly the open source community?

Debian Etch IPv6 howto

So you want to set up IPv6 on your Debian box? Sick and tired of the fact that you can’t test the new stage of Internet addressing because your ISP simply just doesn’t offer IPv6 connectivity yet?

Well, let me be the first to tell you that this just isn’t the case. You will actually find it rather surprising just how easy it is to set up, and how little time you’ll be spending doing it. Once you’re done, you’ll be wondering why you didn’t do it sooner.
