acer aspire one – a netbook experience

I mentioned in an earlier post that I had recently acquired an Acer Aspire One (AAO) netbook. I chose the AAO in preference to any other of the netbooks on the market for two reasons – firstly it looks a lot cooler than most of the competition (particularly in blue – see below), but secondly, …

egroupware mail with dovecot and postfix

I have recently built an egroupware system to be used as a social networking site. The application suite itself is relatively easy to install and configure, but the webmail system it offers (a fork of squirrelmail called felamimail) is rather poorly documented. It took me some time to figure out how to authenticate mail users …

webanalytics – just say no

I have just built myself a new intel core 2 duo based machine to replace one of my older machines which was beginning to struggle under the load of video transcoding I was placing upon it. The new machine is based on an E8400 and is nice and shiny and fast. Because it is a …

where did my bandwidth go

Have you ever wondered what was eating your network? Would you like to be able to check exactly which application was responsible for that sudden spike in outbound traffic? NetHogs might help. This neat little utility calls itself a “small ‘net top’ tool”, and that is exactly what it is. NetHogs groups bandwidth usage by …

implementing mailman and postfix with lighttpd on debian

I recently needed to set up a mailing list for a group of friends (my bike club). I had become tired of mail bounces and failures because we were all relying on an out of date list of addresses originally cobbled together by one member. That list of addresses was routinely used in “reply all” …

backtrack 3 released

Any half decent sysadmin will routinely test the security of his or her own systems. A good, and sensible, sysadmin will follow up those tests with an independent security audit by a professional company – preferably one which is a member of a recognised industry body (such as CREST). Finding the holes in your security …

ssh through http proxy

On a mail list I subscribe to I have recently been involved in a discussion about the restrictions sometimes placed on users of WiFi hotspots or hotel networks (to say nothing of the restrictions placed on corporate networks). Some of the suggested solutions involve tunnelling ssh connections over http(s). Other solutions assume that the network …

reflashing the BT home hub from a linux PC

As I mentioned in an earlier post, I found several references to successful reflashes of the BT hub to a genuine Thomson 7G image on a variety of sites. None of those sites gave instructions as to how to do this if you run a linux PC. So I have documented how I did it …

update to ripping DVDs to a sony psp on linux

Since writing the entry below, I have discovered a much simpler way of ripping and transcoding DVDs – k9copy. I really should have noticed this earlier because I investigated k9copy when I was playing with dvd::rip and winFF as GUI tools for ripping. I had (stupidly) assumed that k9copy could only copy a DVD to …

ripping DVDs to a sony psp on linux

I spend a lot of time on trains – I mean a /lot/ of time. My daily commute amounts to around 6 hours in total each day. Of that, at least 4 hours is spent sitting on a train avoiding listening to the cacophony of irritating chunterers and morons on mobiles. The worst period is …

vinyl to digital

Recently you may have seen adverts in a wide variety of publications for a USB turntable. This product is aimed at people (like me) who have a collection of old vinyl recordings but no longer have the means to play them as they have moved to CD and/or digital recordings. Most of the turntables I …
