I had an issue recently where I wanted some data to get to all machines, all at the same time. The data would not be requested – I needed the data as it came in – from my CurrentCost meter – for purposes of testing around the house on the laptop. The solution was to [...]

Serial over wireless
June 19th, 2010 · No Comments
I spent much of yesterday afternoon and night trying to locate a RS232 or RS485 to bluetooth circuit that needed to be, cheaper than $50 (the cost of running the cable myself), could be powered by a 9V battery or a combination of AA batteries, and the result at the other end had to be [...]

MySQL Upgrade 5.0 to 5.1
June 11th, 2010 · No Comments
A boo-boo! (See the end, I found a solution). I was testing an upgrade for MySQL, from 5.0 to 5.1, to gain Row Based Replication instead of Statement based replication (as statements are a cause of SBR breaking, and it doesn’t proceed til I tell it to). So, in my usual lazy, just do it, [...]

Hardware Failures
December 5th, 2009 · 1 Comment
After travelling 460KM today, I’ve discovered how annoying a hardware failure can be. My colocation box is a HP DL360, G3, so it’s not exactly bleeding edge, but it’s a fantastic server, does it’s job and does it reliably. Last night, we had a planned outage for just a short time to move the box [...]

Squid: Intercept traffic
September 27th, 2009 · No Comments
I was bored this weekend, so after finding some YouTube traffic occurring from one of the PCs on the network, I decided that I’d play with Squid, which is a very powerful, and flexible proxy server. It has many different methods of operation, and can be used in different ways, such as a simple proxy, [...]

Cisco Access Lists
August 17th, 2009 · No Comments
For a while this afternoon, the wireless network was being used and the user was a victim of an MSN virus – this is easily identified by the links to ‘naked pics of me’ – as if they exist on the internet, I thought my servers were more secure than that (no, there are no [...]

Stop spammers!
February 27th, 2008 · No Comments
One of the reasons I can see spammers continually trying to connect to a server, is because they get rejected quickly, and have more than one bot to go and retry. I think the better solution to this issue (and issues related to SMTP auth attacks, and 550 errors), are having an error counter in [...]

ADSL2+ Dropouts improving
February 11th, 2008 · No Comments
For some reason the drop outs we were experiencing nightly on the ADSL2+ service have improved, such that we haven’t had a drop out since 7AM, and before that, it was 6PM the night before. That looks to be improving, but we won’t have anything definite til tomorrow, after tonight, so that we can see [...]

Virtual Machines – Lowering the rise.
January 24th, 2008 · No Comments
Virtual Machines are a great way at hosting multiple services, and keeping your overall costs low. Computers have become very much so beefed up that the grunt they have spends a lot of time idle, and only peak loads when you are doing intensive tasks, even then, they generally keep within 50% of the processors [...]

Outdated Hardware: When do you say no?
January 21st, 2008 · No Comments
I think that when you look at a computer, you are looking at a rapidly devaluing asset. Technology evolves very quickly, so quickly that what is the latest and greatest quickly becomes the oldest. I was working with an old machine today that presented itself with symptoms of rebooting, crashing and a general slowness. I [...]

Internet Censorship – A fix for a non existent problem
January 10th, 2008 · 2 Comments
There was an article published in Australian IT, located here: http://www.australianit.news.com.au/story/0,24897,23021828-15306,00.html Essentially, the author claims that filters are ‘needed’ to battle child pornography. I disagree, it is not filters that will stop the distribution of child pornography, and it is not filters that will protect children from finding inappropriate content. Filters will simply not do [...]

Apple Airport, Securing the wireless network

Telstra will be facing tough competition in the 3G arena, after Vodafone announced it will boldly go where no one else has gone to yet. Creating a competitive, fairly priced 3G mobile network that will rival Telstra’s. Amazingly, reports from Vodafone indicate such an upgrade to the Voda network would cost less than $500 million.

Raw power test results.

I didn’t really post these up before, didn’t consider them relevant, and was too busy getting a licence to drive to actually run the tests. But today, out of curiosity, among others, I decided to determine what uses how much power, and found some rather interesting results. We did the testing by finding the base [...]

Flawless system changeover
November 20th, 2007 · No Comments
The excellent part of having identical (or near identical) hardware is when something cops a nice drink of Sprite, you can simply swap the components over, and power it up and your good to go again. You can’t generally do that when swapping between say an Intel 865PE chipset, and an Intel P35 chipset, simply [...]

Unfortunately (and its very unfortunate), the update I planned to release tonight isn’t going to go ahead as planned due to an issue with a particular provider. The particular provider issue wasn’t determined until just recently, but has been fixed. The reason for the delay? Well, I was investigating that issue and the time it [...]

Server Hardware “Failure” causes delays

Billion VoIP Routers are Australian Broadband Friendly?
October 28th, 2007 · No Comments
Participating in a whirlpool thread recently, as to whether a Linksys WRT54GP2 is better than a Billion 6404VGP, I chose the Linksys over the Billion, for a few clear reasons. 1. Many Linksys devices have Open Source firmware available, so you aren’t pestering the manufacturer for a fix, and you can customise the firmware as [...]
