GNAT 2012 for Debian Wheezy

For purposes known mostly within our company, I’ve created a magic makefile that takes care of most of the work involved with getting a GNAT 2012 (and up-to-date various support tools) up and running on a Debian. The makefile requires you to download some files manually, but that’s okay, as it gives you a great […]

If you’ve ever created a Linux virtual machine image for distribution, you have probably encountered this problem. The Virtualization is not really important – the problem exists on VirtualBox, VMWare, KVM, Xen and others supporting Linux guests. So, what is the issue exactly?

Proftpd and LDAP on Debian Squeeze

This is a short howto (hopefully) providing enough information to install Proftpd and use LDAP as user database. Background I have become obsessed with LDAP – at least for the time being.
