Scripting a ssh tunnel
Sometimes I wonder why I put up with some inconveniences in my work flow. One particular issue I have for a long time is working with ssh-tunnels. It always goes like this: I start a ssh tunnel or other proxy, run a program that uses this proxy and use it until I am done with it, and finally close the proxy afterwards. For a long time I was doing this manually using a terminal, until I finally got fed up with the tedious routine and wrote this simple bash script:

Saxion en CAA, losmakelijk verbonden 
Zoals ik al eerder schreef, was boterde het niet lekker tussen het door CAA-beveiligde netwerk van het Saxion en Linux-gebruikers. Servers die toegankelijk waren via het Internet werden afgeschermd voor het interne netwerk en Linux-gebruikers werden min of meer gedwongen om door allerlei hoepels te springen om hun werk normaal te doen. Sinds kort niet meer: de weg naar de schoolwebsites, de Subversion-server en de Linux-systemen is twee dagen geleden vrijgemaakt voor Saxion-gebruikers zonder CAA
