Lame but mildly successful hacking attempt on my ubuntu 10.4

craig — Fri, 23 Jul 2010 00:29:28 +0000

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.

Tether your Sony Ericsson Aino or U10i on Linux / Ubuntu

craig — Fri, 02 Jul 2010 01:32:15 +0000

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

How to use an Xbox1 controller on your PC

craig — Sat, 26 Jun 2010 13:24:10 +0000

I wanted to be able to use my old Xbox1 controller to play racing games on my pc.

I found here http://fury-tech.com/en/Guides/Xbox-Controller-Pc-Conversion-Mod/

Some basic instructions but i did not want to cut up my controller cable but I had an old bricked Xbox in the cupboard that i could pull the ports out of and cut them instead.

Xbox socket out of the bricked Xbox

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

Solder and heatshrink

Post solder and heatshrink

Final product

Result of “lsusb” command on Ubuntu

Command line showing success under Ubuntu 10.4

I’m still trying to sort out the driver situation for windows 7 64bit and windows vista 32bit.

I will update this post when i have more info but just two links for now…

A Great SVN GUI for Ubuntu

craig — Sun, 21 Mar 2010 05:21:12 +0000

I have been fighting with a mix of CLI and GUI tools for linux for ages now. After having a great experience with TortosieSVN for Windows to move to linux and not find anything that suits me was quite a surprise. After google led me to http://www.doknowevil.net/2009/04/28/nautilussvn-finally-an-svn-gui-for-linux-that-doesnt-totally-suck/ i started to use http://rabbitvcs.org/ using the PPA for ubuntu it looks and works great.

If you want a context menu full featured SVN client built into Nautilus and a few other apps check it out

How to read fuse bits from Atmega128 Avrdude

craig — Sat, 12 Dec 2009 08:23:25 +0000

avrdude -p atmega128 -P usb -c usbasp -U lfuse:r:low:r -U hfuse:r:high:r

This makes two binary files called low and high

A few atmega links so i can find them again

A nearly up to date photo summary of pinball table

craig — Mon, 31 Aug 2009 14:53:57 +0000

Basic table layout mostly finished now that the aluminum rails are installed.

Early flipper prototype.

Flipper assembly.

The solenoid closes and pulls on the short piece of aluminum rotating the bolt in the top left that is attached to the flipper on the topside of the table

The shooter assembly.

The complete flipper.

The completed front of the table.

Two sets of three targets.

The ball strikes the front circle and pushes the backplate against the ‘L’ shaped part screwed to the floor. Electrodes are connected to the two components and this will be used to send score signals to the micro controller.

My first bumper finished.

I will need to replace the rubber. As the ball strikes the rubber the rubber presses on one of the two switches which trigger the hammer (in the middle) which hammers back on the rubber.

The underside of the hammer

The drink holder to be fixed to the side of the table

The front underside of the table showing both flippers finished and the ‘safety light’

A dell (its not quite standard) small form ATX power supply and power plug

Underside shots of both flippers, one hammer and the powersupply

This is nearly the table up to date, the second hammer has been finshed and i have started to design the round bumper things to go in the back. More at the end of the semmester.

Pinball Costings

craig — Thu, 13 Aug 2009 12:03:50 +0000

I have added up all the costs for the pinball table so far.
The PDF came out a bit messed up but check out the the spreadsheets for better view.

090813 Pinball Costs.xls

090813 Pinball Costs.ods

090813 Pinball Costs.pdf
I’ve taken a heap of photos that i haven’t put up yet but maybe tomorrow.
The project will have to be put on hold now for the rest of the semester but hopefully ill get back into it in the holidays.

Plunger, Front curves and flipper bumpers

craig — Sun, 12 Jul 2009 13:05:26 +0000

Today i installed the plungers on both sides

Added some nice curves to the front cause i wanted the ply 3 layers deep at the plungers to keep them straight. They will probably need to have some kind of sleeve though to keep in square and reduce the wear on the ply but for now its not too bad.

I have also made some changes to the bumper that leads onto the flipper. It was just temporary before so i adjusted it to point in the right direction.

First flipper installed and working

craig — Sat, 11 Jul 2009 13:50:01 +0000

I have installed the first flipper, its a bottle opener keyring bolted to a M10ish bolt that connects to the underside flipper assembly.

The underside flipper assembly is a few bits of aluminum channel and a 240V actuator there is also a small spring used to return the flipper to its home position.
