Setting up a Squid forward proxy can be a pretty daunting task since Squid is an extremely flexible piece of software. In this article, I'm going to provide a minimal non-caching, authenticated configuration. I have tested this with Squid 3.1.12 on Ubuntu 13.04, but with minor adjustments …

A few days ago I bought a larger and faster disk for my Dell Precision M65 notebook. If it wasn't for the new disk, I would have never tried the latest Ubuntu (13.04, aka "Raring Ringtail"), because 12.04 worked fine for me. Feature-wise I haven't noticed a lot …

Recently, I have been playing with Kerberos, a popular Single Sign On system (SSO) that is used in many large organizations. My first contact with Kerberos has been at university in a network security course, but that only covered the cryptographic part, not the more practical issues like setting up …

For the first time …

In Ubuntu's Unity, you get four workspaces per screen, arranged in two rows with two columns each. Fortunately, there's a way to get more desktop space, but in Ubuntu 11.10 it takes a bit of searching.

It's amazing how sometimes problems solve themselves. Since my last article, I got a new home router (a FRITZ!Box Fon WLAN 7320) that nicely solves the problem of accessing network devices with dynamic addresses even without Zeroconf.
My router also acts as a DNS proxy and provides a few …
