  • How to save/restore iptables rules on Ubuntu?

    This might be an obvious thing to old Linux-heads out there, but it sure caught me off-guard, so there might be some use in spelling it out: iptables-save and iptables-restore do not actually save/load the iptables rules to/from an external file. You are responsible for redirecting the output of iptables-save to a file and modifying…

  • Toying around with andLinux

    I don’t remember exactly where I heard about it (although I seem to remember that it was on the Ubuntu UK Podcast). andLinux is a package based on coLinux (Cooperative Linux), which in turn is a port of the Linux kernel to the Windows platform. How does that work? The short (and somewhat inaccurate) description…

  • WPA2 is still hard

    Some time ago I found out that you have to install some not-so-well-documented updates (which are not delivered automatically by Windows Update) to use WPA2 to encrypt the traffic of your wireless network (and it is advised to use WPA2, since all the prior standards have known weaknesses). However I was unpleasantly surprised that support…

  • Booting FreeDOS with GRUB

    To toy around, I decided to install FreeDOS on a real system running Ubuntu. This post will document the process of adding an entry to the GRUB menu loader to boot it. Some small notes: Resizing partitions with GPartEd is somewhat funky (no global progress bar) and can take some serious time (if you are…

  • Disabling the Zoom plugin for Compiz

    I was playing around with a 8.10 Ubuntu install and I must have pressed a key combination, because the screen magnification was turned on. It was all nice and smooth, the only problem was that I didn’t want it! (BTW, almost the first thing I turn off after a fresh WinXP install is the accessibility…

  • Installing guest additions for VirtualBox with Ubuntu 8.10

    I installed VirtualBox (the OSS version) from the Ubuntu repos (in hindsight it may have been better to use the VB repos, but I’m just lazy), and when I tried to install the guest additions in a WinXP VM, it complained that it can’t find the VBoxGuestAdditions.iso. The solution: Download the corresponding iso from here…

  • Ubuntu 8.10 comes with Perl 5.10!

    I just found this out: Ubuntu 8.10 (in its alpha version, which means that it probably will be true for the final version too) with Perl 5.10! W00t! I better read through the changedoc it seems :-).

  • Testing Ubuntu 8.10 Intrepid

    Disclaimer: you should do this on a computer you want to work on only if you like taking risk, since it very well break some things (and in fact it has for me – luckily I managed to work around the breakage). The process itself is pretty simple: You edit your /etc/apt/sources.list and replace occurances…

  • Resolving the problem with inserting formulas in OpenOffice with Ubuntu 8.04 (Hardy)

    While writing some text (under Ubuntu 8.04 Hardy with OpenOffice 2.4) I wanted to insert a formula and much to my surprise the Insert -> Object -> Formula way grayed (greyed?) out. My first reaction was that this is probably because I was missing Java (or more precisely: OpenOffice didn’t recognize my installation of the…

  • Living on the edge with Ubuntu

    As I said earlier, I’m not very impressed with Ubuntu 8.04 (hardy), but I’ll give it an other chance. There are some rumors floating around that July 10 there will be some major updates and the steady stream of updates seem to fix a few issues as well. Warning! Don’t do this if you can’t…
