Encryption Overhead – Sometimes Good Ol’ FTP is the Answer

2010-08-30T00:54:54+00:00

I just started copying some files from a Windows XP Pro VMWare VM to a Redhat 3.1 Server VM hosted on their own private network on a VMWare ESXi 4.x server. Using WinSCP from the XP Pro Client with SSH as the transfer protocol I was seeing ~5,000KB/s. So I stopped the transfer and selected [...]

Set up your own Linux LAMP server painlessly as a Windows virtual machine

2010-08-28T14:07:04+00:00

iTWire: Even the most Microsoft-ardent developer will know web hosts favour Linux, Apache, MySQL and PHP over Windows, IIS, ASP.NET and SQL Server. Thanks to virtualisation the days of dual booting are over. Here is how to set up a streamlined LAMP development environment on any Windows PC.

Xperia X10 and HTC Desire

2010-08-23T11:59:39+00:00

So my contract with Optus was over.. I went and re-contracted with them and got myself a Sony Ericsson Xperia X10. Great phone and awesome 4″ screen, but the battery life is terrible, and I had to charge mine atleast 2 times a day to get a full day out of it. After a few weeks of this, and terrible Optus coverage and endless problems – after many many phone calls and hair pulling I got out of my contract and went to Telstra and got the HTC Desire… They are awesome phones, I am still trying to work out some of the cooler parts of Android – and hanging out for the 2.2 Froyo update – but I am enjoying having the Android phone over having my old iPhone 3G..

Maybe when I get time I will upload a few reviews of apps etc.. but we shall see how we go!

Roof Restoration

2010-08-22T12:18:08+00:00

Our humble timber cottage has an old tin roof. We can’t afford to get it replaced at the moment but have gotten it pressure washed and painted in Shale Grey Colour. So now we are waiting for Google Maps to update it’s satellite imaging to pick up the change.

Back to Ubuntu 10.04

2010-08-21T13:19:34+00:00

I have for several months been giving Fedora 13 a go as my primary OS. Fedora is what it is— A beta release for a product that will be rebadged and released when it’s finished. As a distribution it’s not really playing in the same league as Ubuntu. The polish and completeness come when it [...]

Linux wall warts – small on size, big on possibilities!

2010-08-17T22:58:35+00:00

iTWire: Every geek and technology lover will undoubtedly have stumbled across online adverts for tiny headless Linux-powered devices that are barely larger than the power point they plug into. What can you actually do with them? Plenty, it seems!

SlashDotted! Yeah!

Separate Websites should be run under separate User Accounts

2010-08-16T10:14:39+00:00

If you have an account with a webhost which allows you to run multiple domains (or even `unlimited’ domains ala Dreamhost). You may be tempted to run multiple websites under the default account that is provided by the hosting company. But while convenient, this has a pretty major security pitfall. For example with my webhost [...]

jQuery .find() on a namespaced XML node fails on Google Chrome

2010-08-16T09:23:26+00:00

Ran into a problem with a jQuery AJAX script that parses returned XML. It wouldn’t work on Google Chrome when looking for a namespaced xml node using jQuery.find(). Apparently this (xml namespaces) can cause jQuery some minor heartburn but it’s not a show stopper. A namespaced nodename in XML has a name space prefix a [...]

Fanboy Post Alert – Why can I run a secure modern operating system on a P4?

2010-08-11T13:39:15+00:00

My home computer is a P4. P4′s are like 6+ years old. However it’s still suitable for what I use it for. In fact it’s performance has been improving of late. Why? Linux is maturing and the people who are designing the entire GNU/Linux eco-system are optimizing. Here are some recent improvements: Openoffice starts in [...]

Dia – Joining Lines where they Cross over Each Other

2010-08-04T23:50:01+00:00

Dia is a great Open Source diagramming program that has extensive `shape’ libraries for a lot of different applications (I use it for drawing network diagrams and flow-charts). When using Dia one of the questions that arises fairly regularly is: Is it possible to create a node at line crossing points? or at arbitrary position [...]

XML POST Proxy Script using PHP and libcurl

2010-08-03T00:58:08+00:00

This is the simplest answer I could find for a client needing to POST an XML SOAP message to a server in another domain. Not sure on the security because the POST isn’t validated so it just passes on whatever the client sends. libcurl has a lot of options <?php # # // [...]

Cisco 877 Continual Reload

2010-07-29T11:04:25+00:00

I used Cisco’s SDM to configure the stateful firewall component on a Cisco 877 but I let it add all the automatic Instant Messenger rules. That’s when things started going wrong. The Cisco crashed and reloaded… probably 10 times a day. Deleting the IM stateful inspection rules fixed the continual reload problem. The crashinfo file [...]

Lame but mildly successful hacking attempt on my ubuntu 10.4

2010-07-23T00:29:28+00:00

Ive seen this attack occur on a windows xp machine running realvnc a number of years ago but this time it hit my ubuntu 10.4 machine.

I am currently working away from an internet connection so i am using my phone tethered with my computer to get online (see my last post). This configuration gives my laptop my public IP address ( ie no network address translation).

I was sitting at my machine just about to start programming and all of a sudden my mouse starts moving.

I looked at the gnome to panel just as it flashed the “your computer is being remotely controlled” message from the VNC server vino built into ubuntu.

The remote connection then typed the following message as if it was trying to run that command.

You can see the command now in line 8 of my program. Windows users will recognize this as an attempt to open the windows command line.

The remote connection terminated a second later and the attack was over.

I then opened my remote desktop preferences to check whether or not I had turned it on

It doesn’t appear that anyone should have had access as the service was not really activated.

If you look closely you will see however that even though the options are greyed out the box for “allow others users to control…” was ticked and all the security boxes were unticked. I cannot remember what settings i had before the attack and its possible that as part of the attack the settings were changed but as all it tried to do was run a windows command (as far a i could see) i can only assume that the attack was probably not written to attack gnome.

All in all made for a good laugh seeing a windows attack play out on a linux machine. I just hope nothing else happened that i didnt see.

Edit: I had a bit of a flip through my system logs and it looks all clean.

Cisco Network Topology Icons

2010-07-12T22:11:24+00:00

If you use Dia or another open source diagramming package you may need some network infrastructure icons. Cisco publishes some here http://www.cisco.com/web/about/ac50/ac47/2.html Note: Dia already includes most of these which were converted several years ago when the licensing was favourable but the recent licensing doesn’t appear (IANAL) to allow Dia to package them now.

Circular Reboot due to Harddisk Removal

2010-07-08T22:12:57+00:00

Tether your Sony Ericsson Aino or U10i on Linux / Ubuntu

2010-07-02T01:32:15+00:00

My carrer is Optus in Australia and i’m using Ubuntu 10.4 and i want to be able to connect to the internet via my sony ericsson aino also known as the U10i

Heres the quick how to.

Plug in your phone with the usb cableIt will then try to connect to your computer and look for the windows software (this default can be changed)

Click cancel on the phone and then choose the linux option

Now on your ubuntu desktop click the network manager icon in the system tray

Now disconnect from the USB wired network this appears to take priority over the 3G connection so the easiest way to get around it is to disconnect from the wired PC-Phone network.

Now Right click the network manager icon

and choose edit connections

Select the Mobile Broadband tab and edit the connection

The phone number shown is generally accepted as common for most carriers but the APN will come from your phone.

On your phone go to Settings–> Connectivity –> Internet Settings

It should look something like this

from here the APN is “internet” as that is what is written under the Connect using heading.

Now click Ok to all the open windows and click on the network manager icon again and now select “Optus” or the name of your carrier and you will be connected

Cut the end of the USB cable

Usb cable with the unneeded end cut off

Line up the colours (the extra yellow from the Xbox socket is not required

USB cable and the Xbox socket ready for solder
