  • Check open ports with Python

    Everyonce in a while I run into problems testing new setups just to find out that a certain port just isn’t reachable from within our company network. This simple tool should make it easier to find open ports for quick testing. Note it’s not the fastest tool for huge numbers of ports (e.g. 1-65535) but…


  • Linux ACLs and sticky Users

    Sticky and suid bits are quite helpfull tools when it comes to keeping the correct permissions throughout a set of folders and files.

    Ok, I know this has nothing to do with security and I’m just writing about typical, everyday sysadmin stuff right now. But this problem has cost me way too much time to not be sharing the solution with the world. The problem I was trying to build the owncloud sync client mirall when I noticed…


  • HA-Proxy for the win

First, I already had MySQL 5.6 installed but no data was stored there, so backup wasn’t necessary Normally, this should do the trick But in my case, mylsq-server-5.5 selected mysql-common (5.6) as dependency, so I had…
