I don't use Linux and I am posting this thread purely for educational purposes and/or for anyone running a Linux server and seeing it behave strangely. Holliday cracking. The author explains his thought process really well and makes it quite an interesting read.

A friend of mine asked me to have a look at his Linux-server. "It behaves strangely" he said, most notably the web-server apache refused to start. It turned out to be more than just a problem with apache.


I already had an account, so I started to poke around. The first thing I noticed was some strange ls behavior...
