Google Streetview in the UK… updated!

11-Mar-10

So the little birdies were correct – Google have just updated Streetview for the UK. They’ve spent the last year or so photographing the length and breadth of the country, and now it’s all there to see, including such wonders as this blurry-faced chap:- Yeah, that’s me, on my way out to work. I’ll ignore [...]

iproute2: Life after ifconfig

24-Feb-10

The standard network tools ifconfig, netstat and route will be familiar to anyone with more than a passing interest in UNIX or any of its derivations. Linux is no exception, and if you hop on to your nearest Linux machine, you’ll find these installed. However, for the past few years ifconfig and its ilk (often [...]

The Great White North

22-Feb-10

Sometimes, people decide to do something big, something life-changing, something that will undoubtedly cause a huge amount of upheaval in their life. I’m talking about emigration.

Fixing Likewise startup scripts on Debian Squeeze

11-Feb-10

Just a quick one, this… If you install Likewise Open on Debian Squeeze, you may notice that it doesn’t start on boot-up. The reason is because the new dependency-based boot sequence doesn’t like the init scripts Likewise provides. Luckily, it’s pretty easy to fix. First, make sure you have chkconfig installed (apt-get install chkconfig if [...]

IPv6 for a Linux generation

07-Feb-10

IPv6 is nothing new – it was finally standardised back in 1998 in RFC 2460, and virtually all operating systems have supported it now for at least 5 years, so most people are in a position to give it a try. If you’re one of the lucky ones, your ISP might provide native IPv6 connectivity [...]

GnuPG – RSA key-pair mini-Howto with stronger digests

02-Feb-10

(Note: This was originally posted on my previous blog, but I’ve noticed that it’s being linked to, so I’ve reposted it here) I’m not a mathematician (or a cryptographer) so I’m happy to take this post‘s word for it about a recent attack against SHA-1 (short PDF here). The post goes into detail about changing [...]

Authenticating Active Directory users on Linux with Likewise Open

28-Jan-10

Historically, if you wanted to use Active Directory to authenticate users on a UNIX box, you were pretty much limited to using LDAP. This works fine for some people, but it’s not particularly elegant – especially if you’re having to create users home directories all the time, which negates some of the point of centralising [...]

IPTables: Fun with MARK

27-Jan-10

One thing that’s always bugged me about IPTables is the lack of a way to use groups when writing rules, which can complicate things if you’ve got a potentially large rulebase. One way round this is to use something like fwbuilder, which gives you a graphical interface not unlike Checkpoint‘s SmartDashboard GUI for their Firewall-1 [...]

OpenSSH and OpenSC for Debian and Ubuntu

23-Dec-09

I’m using OpenSC at the moment so that I can repurpose an otherwise unused Aladdin eToken to hold SSH keys. I could go through the process involved in setting up the token, but as this chap has already done a thorough job, I won’t go into detail. Unfortunately, the openssh-client package from Debian (and Ubuntu) [...]

22-Dec-09

I released version 0.0004 of IPTables::Log early yesterday morning, which mostly consists of test fixes. If you’re interested, have a look at the entry on CPAN.
