how to use teambox for project management…

May 1st, 2010

In the last weeks I was looking for an open source web based project management tool and I’ve found – A very good pm-tool with twitter like communication functions that can be installed on your own server :)

In this article I wanna show, how to use teambox for management of an IT infrastructure project. Therefor I’ve created an example project which is called “application delivery infrastructure” which goal it is to implement Citrix XenApp, XenDesktop and Access Gateway with Provisioning Server and XenServer – A real IT infrastructure project ;-)

OK, before we speak about project management, we have to define what we wanna manage. In theory project management includes the following dimensions:

  • requirements (or goals) management
  • problem management
  • tasks/time management
  • ressource management

two different proxies used...

The most interesting part was then to google some buzzwords and see how many hits one gets with an american ip and how many hits one gets with a european ip – in some cases there is a huge difference ;-)

For all of you who would like to try it yourselves, I’ve written a how-to, which you can download in the articles section of this site. Have fun…!


[...] This article describes the setup of a proxy-server in a cloud. You can use a proxy like this from everywhere through the internet. Reasons to do this could be:

  • Your internet access is filtered but you need access to sites which are filtered.
  • You want to have a log of all sites and files you’ve visited from different browsers.
  • You need to speed up your internet connection through caching.
  • You want to filter the internet access of your kids. [...]
