My poor abused laptop has a habit of loosing it's DVD drive on a regular basis, after a few drops too many. Normally I had simply rebooted after pushing back in the drive, but I was feeling like a dirty windows user with that method :)

As it turns out, Linux provides the answer. In Ubuntu, simply install "hotswap" using apt-get or your preferred method. To rescan for IDE devices run the following command:

 sudo  hotswap -c 1 rescan-ide

Ignore the errors and simply enjoy your DVD :)

We have had a nice native IPv6 network at Blacknight for a while. Until recently we haven't been making much use of it, but that is changing. Various hosts on the network such as www and mail are gradually being IPv6 enabled. Documentation for setting up native IPv6 on Redhat based distributions was a bit lacking so I've included the steps for adding an IPv6 address to eth0 below. I've also added details on how to add it to Debian based distributions.

I have been using IE4Linux for a while in order to test some websites I'm responsible for and make sure that they are useful to people who still have to use Internet Explorer. To make it even handier, the IE View extension for Firefox works well under Ubuntu.

The only problem I've run into is that the "find" button in the IE View preferences doesn't like Linux file paths, so to use it you have to enter the path to IE manually. In my case this is /home/niall/bin/ie6. Once it's setup properly, I can rightclick on the link and select "Open Link Target In IE" and suffer for a few minutes in the name of testing!

Dell Commiting To OpenSource

| 1 TrackBack

It looks like Dell are beginning to see the light! They are now commiting to use only hardware that has drivers in the mainstream kernel where possible. It will be very interesting to see if they can put some pressure on the makers of graphic cards, namely ATI and Nvidia, to open up more.

A Dell laptop with no binary blobs to cause random crashes appeals to me after living with a laptop with an ATI graphics chipset for a few years.

One of the better reasons for using Firefox are it's extensions. Currently I am using the following:

  • Web Developer
    Very handy toolbar that gives a lot of essential functions for anyone who does ANY work with html.

    Pointless really unless you are like useless info. Has already turned up some interesting facts :)

  • User Agent Switcher
    Another good extension which is good at turning up interesting ways of getting into sites!

  • Flashblock
    I tend to dislike useless flash ads, so anything that kills them while leaving the option of clicking on flash games for a bit of distraction is always going to be handy.

  • ShowIp
    With the work I do on a day to day basis, it is very handy to know what IP address you're looking at when you view a site. This simple extension displays the IP of the site in the status bar and offers shortcuts to online DNS utilities if you click on the IP.

  • Switch Proxy
    My laptop is thrown onto lots of different networks, often with different proxies. This extension gives me a nice drop down menu with a list of proxies and can be a nice time saver.

Is there any other handy extensions floating around the net? I don't want to totally bog down Firefox, but things that make life easier are always welcome.

Hot Captcha

| 3 Comments | 2 TrackBacks

Have come across some strange captchas before including one where you had to select kittens. Hot Captcha has to be the strangest though. It takes three high scoring female (or male) pics from Hot Or Not and six not so hot pics and you have to select the three hottest. How long before this will be implemented on a production site?

I have had no optical drive in my Laptop for a while since the original fell out a couple of months ago. I finally put in a DVD Drive this evening and attempted to watch a DVD. I started up MPlayer and got the following error:

libdvdread: Error cracking CSS key for /VIDEO_TS/VTS_01_0.VOB

This was happening for every DVD I tried. As it turns out, the error seems to have been caused by the fact that the region on the DVD Drive I put in was set to Region 1 (America).  Changing the region was fairly easy. There is a imaginately named utility called "regionset" available from apt (apt-get install regionset) which can quickly set the correct region.

Run it as root (sudo regionset) and tell it that yes, you do wish to change the dvd region. Then put in the number for the region you're in. Once this is done, you can then hopefully enjoy your movie.

One of my pet annonyances when browsing around on the net is sites where you have to register for no good reason. I have enough useless accounts as it is. What's even more annonying is when they return a different result to the search engine bots so that more than just the registration page is indexed.

A prime example of this is When searching for current Irish news it usually ranks fairly high on Google, however all the pages require you register first before you view them. The registration gives no advantage to people like me who just want to a quick look at the latest news. I suspect that I'm not alone and that lots of people will just go back and look for another site.

Unison's simple user agent checking makes it very easy to get in unmolested though. The User Agent Switcher Plugin for Firefox allows you to easily set exactly what user agent you want your browser to appear as. The GoogleBot isn't in the list of Useragents available, but it is easily added. Switch to GoogleBot as your useragent, and magically you will have full access to the Unison site.

I know that Unison will probably close this hole within a few days now, but it's nice to be able to make a point. According to Google's Webmaster Help Center "crawler only" pages are a thing to avoid. I would class pages that react differently to GoogleBot as "crawler only" pages.

If Unison want to require people to register in order to get nice features such as customization, then grand, I have no problem with that. However, how much traffic are they missing out on by having the register page for everyone? And how many advertising impressions are they missing out on? I know that if I go to the BBC News site I will usually end up going to other stories which interest me, which means more page impressions on the BBC site. More impressions, more chance of clicking on ads, more money!

In this day and age it is senseless to have such stupid restrictions on a site like Unison that has enough content to be a massive earner on advertisments alone.

Update: I somehow managed to forget the user agent I'm using, it is:

Googlebot/2.1 (+

I came across Damn Interesting in my wanderings. I shouldn't be allowed near sites like this as it's too easy to lose hours of my life which could probably be put to more productive use :)

DVD Copyright Notices


Due to a bit of a cold I'm having a quiet night in with a few DVDs. I'm currently trying to figure out the whole idea behind the few minute long "Copyright Theft Is A Crime" crap at the start of some DVDs, which can't be skipped on most DVD players. I'll be the first to admit that it is a crime, but I have bought these DVDs legitimately and so am not really their target audience.

I'm pretty sure that if someone is counterfeiting the DVDs, they will already know that it's a crime. They have probably gotten over that hurler a long time ago.

Unforunately there is no way to easily find out what DVDs have this crap before buying so I can't really bycott the offending products :(

Just in case this woman gets her way:

By using a RSS Aggregator to view this post, you are consenting to buy me a pint next time you meet me in the pub.

If her claim actually succeeds in court, and I hope the Judge has more sense than that, how long before stuff like this becomes common place?

New Ubuntu Logo


What were Ubuntu thinking when they designed the new logo?

Feisty Splash Screen

Or am I just too dirty minded from exposure to the net?

Originally seen here.

Adam has pointed out that SEC are planning on planning on taking action to combat the pump and dump spams doing the rounds. So far trading in 35 companies has been suspended in the aptly named "Operation Spamalot".

It is a logical step to take in order to curb the amount of such spams going out, however you would have to wonder how long before spammers twist the situation to their advantage?  Blackmail anyone?

I have setup FeedOnFeeds for aggregating various RSS feed I'm subscribed to. While not the prettiest, it is a decent piece of software which allows me check all my feeds in one place, and can be checked from any web enabled device. However there is no inbuilt authentication, so I have been protecting it with a htaccess file. Firefox can save the password, but having the password box pop-up every time I open my browser was getting annoying, so I decided to make life slightly easier for myself :) I access the Internet primarily from three ip addresses so it was easy to convince Apache to trust those. The .htaccess file for my FeedOnFeeds folder is now:
AuthUserFile /path/to/htpasswd
AuthName "FeedOnFeeds"
Authtype Basic
require valid-user
order deny,allow
deny from all
allow from
allow from
allow from localhost
Satisfy Any
Some info has been changed, enter valid ips and a proper path to the htpasswd file. When I go to my FeedOnFeeds folder now, Apache will check to see if I'm coming from an allowed ip address. If I am, it will allow me straight in unmolested. If I am coming from an unknown ip address, it will ask for a username and password, and check it against /path/to/htpasswd. Once I enter the right username and password, I will be allowed in. For FeedOnFeeds, the "allow from localhost" line is important. You tell FeedOnFeeds to check the rss feeds you are subscribed to by calling "/usr/bin/GET http:/" from cron on a regular basis. Without the "allow from localhost" line, you have to give GET a valid username and password. The net result of this, is that now I only get asked for a username and password when I'm out and about, which makes me a little less cranky :)

Last January, I headed to the Godfather Pizza website to view their menu and order my uber-healthy supper. When I attempted to call the number for Godfathers Carlow on their website, I got nowhere. I checked a " Take-Away Express" booket that was in the house and got the right number. The number on the website is (059) 941 6666 while the actual number is (059) 914 6666. Being a nice lad :) once I ordered the Pizza, I emailed the only email contact I could see on the site (info@....).

I got a reply back saying that the information had been passed to Marketing Department, and I promptly forgot all about it. I'm just after going to the site to see the menu again, and the number is STILL wrong. I would have thought that something as simple as swapping 2 digits could be accomplished in 2 minutes, never mind 2 months.

I have no idea how much traffic Godfather Pizza get to their website, but seeing as Dominos have recently started taking orders online, I'm betting that the internet using public is a sizable percentage of their customer base. Godfather Pizza don't have the facility to order a pizza online, so the only contact you can have with them if you want a delivery is by phone. How much business have they lost by not having proper contact details on their site?

Update Mar 22th: Looks like the number has been changed. I'm not sure when, but the current last modified time for the page is: 03/20/2007 11:20:18 AM

I'm currently in the market for a new MP3 player. I currently have a Creative Zen Touch 20GB which, in fairness, is a great device. The main points going for it are good battery life and a decent interface. However it lacks USB Mass Storage support, and has a very very annonying "Random" button on the front which I'm too good at accidently pressing.

Standard USB Mass Storage support is the main feature that I will be looking for in the new player. I have about 10G of music on the Zen, which means 10G free. You can transfer normal files to it, however unless the computer at the other end has the correct software, it's not all that useful. If I'm using Ubuntu or Debian, it's not too big a deal as I can simply apt-get install gnomad2, but on a Windows PC the Creative software is up to usual Creative standards. In order words, not the best.

Another nice feature would be Ogg support. I'm not going to re-encode the big pile of CD's in the corner of my room, but I would have no problem encoding new CDs using Ogg. WMA support is very down on my list of priorities for some odd reason :)

From searching around the internet I've come across the following options:

  • IRiver H340: Seems to do all of what I want. Doesn't explicitly say USB Mass Storage Support though.

  • Vibes: Looks nice, but has only 12G of space.

  • Rockbox Based Player: Getting a device and flashing it with Rockbox will mean that even an Ipod will do what I want, and will even give me Doom!!

Does anyone have any suggestions as to what to go for or any experience with Rockbox?

Massive Monitors


I so want one of these monitors. 8 19" LCD monitors for a massive 5120 by 2048 resolution! The biggest problem would probably be massive information overload and subsequent meltdown.

Despite that, Paul, can I have one please? :)

After reading a response to a post I put up on the Irish Webmaster Forum, I headed to the Garda website. From what I can see of it, it is absolutely useless for any informative purposes under Linux.

To give an example, say I want to get the phone number for the Garda Station in Listowel, Kerry. First of all I will go to This will present me with a page with the option to click on "New Visitors" or "Previous Visitors". The only different between the two is that "New Visitor" forces me to read a message from Noel Conroy before having to click the "Enter" link in order to get to the same page as "Previous Visitors" would have originally sent me to.

Once I get to the home.html page I can try to get to the "Contact Us" link. This will do absolutely NOTHING in Firefox. When you click on the link it goes to "javascript:hili('cux','cu');" My Javascript isn't the best at the moment, so I can't figure out exactly what this is supposed to do, but I can tell you for fact that it doesn't work on Firefox on Ubuntu.

I eventually clicked on the "FAQs" button in order to see if there is some reason for the lack of any standards support. I clicked on the "I want to email a Garda Station" link. This kindly informed me that the Gardai "do not have external e-mail facilities for the general public to contact Garda Stations", but gave me a "local stations" link to click. From here I was able to click on Kerry, and was able to find the number for the Listowel Garda Station in a couple of seconds.

What I would love to know, is why the link for "Contact Us" can't be changed from "javascript:hili('cux','cu');" to "stations.html". It takes less characters ( :) ), is compatible with every browser that I know, and is a LOT simplier to implement. It is the same with every other link in the blue box at the top left of the page, every one of them uses the hili javascript function. I don't really care what the hili function is supposed to be able to do, but it is unusable under Firefox.

The Garda website should be a public website which should be available to everyone. The unnecessary complication that has been added to the links on the website means that I cannot use the site. I don't even want to think about how bad it must appear to people who with disabilities who use.

To quote from the NDA website:

Irish public policy includes requirements for government departments and agencies to procure accessible ICT solutions where possible. In particular, all government departments are now expected to have their websites accessible to Priority 1 & 2 of the Web Content Accessibility Guidelines (WCAG) 1.0 from the Web Accessibility Initiative (WAI). The National Disability Authority have adopted WCAG for these guidelines.

There is no way that the Garda website can pass any WCAG test. The lack of bog standed links means that even a simple search engine bot, such as GoogleBot, won't be able to index the site. What even more amazing is that a lot of Gardai email addresses are under the domain. I have no problem with IOL, they provided me with Internet when I was on DialUp, but I would have hoped that the Garda would have their own infrastructure for email.

I have every respect for the job that the Gardai do, however I would have hoped that the Garda Website would be usable be every Irish Citizen. With a little work the Garda Website could be a great resource, but as it stands it is unusable for a sizable minority of Irish Citizens, and not following EU Guidelines for IT. Surely the Gardai should be able to provide a usable website, there is plenty of people in Ireland who can do a lot better job than the current website.

Graphing Rbldnsd Stats With MRTG

A while ago Michele blogged about generating stats from Rbldnsd. Since then I've had to put it into practice. During the post he mentioned Jeff Chan's script for getting the numbers from rbldnsd's stats file. The only problem with this script was that it rapidly ran out of steam when you went over ten zones. This becomes a problem when you consider that a dnsbl like has over 200 zones.

A new script was created in order to get around this limitation, which is available here. If no argument is passed to the script, it will return the aggregate numbers for all the zones, and if the zone name is passed in as an argument it will give the numbers for that zone. In both cases it will return two lines. The first is the number of positve hits on the zone, the second line is the total number of requests to the zone.

In order to use the script with mrtg you will have to edit the $statfile variable to point at where rbldnsd is outputting it's stats. For each DNSBL, you have to setup a target in your MRTG config. The target for would be:
Target[]: `perl /etc/mrtg/` MaxBytes[]: 4800000
Title[]: RBLDNSD -
PageTop[]: <H1> requests </H1>
MRTG should then be run every five minutes using cron.

I have recently had reason to convert an Access MDB file to CSV for use in a mysql database. I don't like the idea of an Access database on a production server and Microsoft has been agreeing since 1999.

As it turns out it is actually very easy, there is GPL software available for the job at If you are using Ubuntu or Debian you can use apt-get install the mdbtools package.

To get the list of tables, you run the following command:

mdb-tables database.mdb

You can then get a CSV version for each table using:
mdb-export database.mdb table_name

You can also convert the mdb into a format required by MySQL. First you must get the put the table schema into the database using the following command:
mdb-schema database.mdb | mysql -u username -p database_name

You then import each table by running:
mdb-export -I database.mdb table_name | sed -e 's/)$/)\;/' | mysql -u username -p database_name

Sed is required as mdb-export doesn't put a semi-colon at the end of each insert statement,  which MySQL definately doesn't like.

After running this, you can now be rid of the horror that are Access MDB files :)

I have a nice plugin for Firefox from HostIP which shows you the country the url you are going to resides in. I was more than a bit surprised when I went for clicking on a link to and saw "Canberra, AU". As it turns out the main Gaa site is being hosted by Telstra Internet in Austrailia. Local GAA sites are being hosted in Ireland, for example is being hosted by Imagine.

On a purely technical basis, this is absurd. From my Magnet DSL, has to go over 20 routers in order to get to Telstra's server. It has to go through less than 10 to go to I would presume that the biggest audience for the GAA's website would be in Ireland. Surely it would make sense to host the site close to it's intended audience?

Getting away from the technical, the GAA receives a lot of money from the Irish taxpayer. I believe that this means that GAA should support Irish business unless there is no local alternative. For web hosting, there is no shortage of competition, my own employer among them. Why aren't the GAA obliged to support local business?

I do believe that the GAA do great work in Ireland. I would prefer to watch hurling or football over a Soccer match anyday. This is why seeing "Canberra, AU" in that little popup was such a disappointment. If anyone from the GAA reads this, please bring your business local!

Great Firewall Of China

| 1 TrackBack

According to, Chinese citizens are unable to get to my blog. Not that this bothers me all that much. What is strange, is that Akismet is catching plenty of spam comments coming from Chinese ip space. Chinese spammers are also having no problem sending lots of spam email.

Are the spammers in China just technically advanced enough to get past the Great Firewall? Or do the Chinese authorities not care about spam traffic? All this is making my decision to drop all email from China at MTA time seem a lot more reasonable.

I mentioned last week how I managed to recieve a unsolicated message on my phone from Since the message was not a SMS, but rather a service message, Vodafone couldn't give me the five digit number which RegTel require in order to do anything about it.

The solution as it turns out is to contact the office of the Data Protection Commissioner. They can act on any complaints about unsolicited spam messages. Details for how to procede with reporting the spam are here.

Since I did the original post, I have gotten a lot of hits from other European countries. For these visitors, I can only suggest that you contact your local Data Protection Commissioner.

Use Of www

| 7 Comments | 1 TrackBack
Michele recently posted about using mod-rewrite to redirect domain.tld to www.domain.tld. Why redirect to www.domain.tld though? Most websites today respond to www mainly because that's just how it's done. However when I'm sending email to someone, I don't send it to user@mail.domain.tld, so why do I have to type "www." to go to the website? The server should hopefully know that I want the website if I'm connecting to port 80 or port 443. Why should I need to type a whole FOUR extra characters :) There is already a campaign underway to promote the deprecation of "www.", it can be found at I propose that Michele changes his rewrite rule to the following:
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^domain.tld$ [NC]
RewriteRule ^(.*)$ http://domain.tld/$1 [L,R=301]
Think of all the w keys you will save!

It looks like Nasa are now releasing satellite pictures of space as fast as they can take them. You can get them here. They are not as high a resolution as what you'll get from Google Maps, but they are still very impressive.
