Heres the shell of an idea I’ve been mulling over recently, we all know that compilers on server are bad don’t we? The common wisdom (and this is often disputed by people who use source based systems) is that people shouldn’t be compiling up new versions of software on the production servers. By omitting the compiler suite and required header files you force compilation to occur elsewhere. The second reason, and I’m not so sure about how current this is, is that you deny an attacker an easy way of hiding their tracks. Read on →

I’ve added a short Perl script called linksinfo to the miniprojects page. When invoked with an absolute URL it will parse through the HTML and pull out links. The text in each href tag will then be displayed. If you use a ‘-l’ then it will also display the target of the link. Why?: This is the first of a couple of scripts I’m writing to help maintain certain meta-data about a website I’m responsible for.

I dislike most modern music (I’m 24 and I’m turning into my grandfather!) but a couple of songs from The Streets last album were good so I decided to give their second a chance; very wise choice. The songs themselves cover a pretty diverse area, from the upbeat backing of “Fit but you know it” to the down trodden lyrics of “Dry Your Eyes” the CD contains a number of little gems. Read on →

For one of the projects I’m working on I needed to see which type of ads Google would choose to bestow on certain pages. A co-worker pointed me at Try Before You Sell at the (unofficial) Google Weblog. While this is quite handy (and easy to use in a bookmarklet) I did find it a little cumbersome. So filled with the drive of an early morning and bacon sandwiches I decided to put together a right click extension for IE. Read on →

Author: Jonathan Hassell ISBN: 0596003226 Publisher: O’Reilly & Associates RADIUS (the Remote Authentication Dial-In User Service) isn’t getting any younger or popular, it’s a specialised technology that very few people seem to discuss and even fewer write books about. Unfortunately the ones we do have, such as this, don’t exactly encourage it’s adoption. The book starts with a solid overview of the AAA process/framework, AAA in this context being Authentication, Authorisation and Access Control. Read on →

In my quest to learn how RADIUS works and the correct way of running my own server I picked up both the O’Reilly RADIUS book and GNU RADIUS, A Reference Manual. Neither of which are exactly ground breaking books. Now I’ve almost finished the O’Reilly book I thought it would be a good time to get my hands dirty and have a play, so I looked at XT RADIUS; which hasn’t been updated since very early in 2002.

I read a lot of books, some of them are inspiring, entertaining and relevant. Some are dull, overly terse and yet still useful; The O’Reilly Radius book is more akin to bad dental surgery. What really annoys me is that I can’t think of a better way of presenting such as dry topic, the book provides detailed coverage that is just as easy to read and understand (and as fascinating) as the original RFC version.

If you are not already subscribed then it may well be worth subscribing to the CPAN RSS feed. It’s very easy to let little gems like Test::URI slip through. The downside of course is that I am slowly running out of things I can’t test!

GLLUG, the Greater London Linux User Group, had a user meeting yesterday. It had about twenty people turn up. While this may not seem too bad this is a group that has peaked at 120 people at a single meeting and had a thriving mailing list. After the three main talks the GLLUG admin team, and a few bystanders (including me), had a chat about what we can do in the future to try and reverse the trend of diminishing numbers. Read on →

I’ve added a new script to the Unixdaemon Miniprojects Page. This short chunk of shell and awk, imaginatively named Find Duplicate Filenames, does exactly what you’d expect. It scans the mounted file systems and prints a list of files and the number of times each name (with the path part stripped) was found.
