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.
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.
OK so it happens so rarely that I had to post about it. On Wed 14 Jul 2010 06:38:24 PM AEST I got this when attempting to put on some tunes to shower by:
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.

Until yesterday I had two hard drives in my Fedora 13 box. Hard disk 1 – /dev/sda was a 200GB Western Digital and hard disk 2 – /dev/sdb is a 500GB Samsung containing my Fedora 13 installation. The Western Digital, after many years of faithful service has died, and so I removed it because it [...]
This post is another one of my memory jogger posts. After posting this I stumbled upon, in the original sense, not the http://www.stumbleupon.com/ sense. A link to http://www.site5.com/hosting/ which seems to have a better approach to hosting than some other hosting companies in that it has normal cheap as chips shared hosting, but also some [...]
This is a handy site if you want to check if a web site you can’t access is unavailable to just you or to everyone else as well. Just append the URL to the end of http://downforeveryoneorjustme.com/ e.g. http://downforeveryoneorjustme.com/en.wikipedia.org
A blog post from the Android Phone. We are nearing completion.

I’m posting this from an Android based phone. Very featureful. A little difficult for my big fingers to type with, but I’m getting better with practice. Battery life is about a day if you use the apps on the phone and keep the phone screen running. Overall I love being able to access the web [...]
You can’t have a website without a web host. It’s like having a house without having any land to build it on. Until you get that virtual real estate, all you have is a design and a plan. Before you go shopping for a web host, you should be aware that there are different kinds [...]
Besides wasting copious amounts of time, which could be better spent communicating with your family. YouTube can also be a fantastic training resource.

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 cable
It 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

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/

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

ADSL performance is predicated on a number of factors. Of primary importance to the potential speed of ADSL is the distance of your house from your local Telephone Exchange. Using Google maps you can roughly calculate your distance from the exchange: You need to know your home address. If you don’t know your address seek [...]

So Ubuntu 10.04 is a thing of beauty and typically I use it above other distributions…. However my spiritual Linux home is Redhat/Fedora I started out with it and even bought the Sybex RHCE book. I even think that the Redhat style of system-config-blah provides a better way of admining a box than the Debian [...]
Been having a look on the web for options that allow backing up a Linux box to a Windows box without first having to create a massive file on the Linux box.

Annoying problem “The process cannot access the file because it is being used by another process” trying to delete a directory.

Tried filemon from sysinternals.com and couldn’t [...]

Recently discovered an old Joomla website that had been hacked by a remote exploit which changed the contents of .htaccess and redirected the connecting clients away to malicious sites. I don’t know how they managed it but I thought that if .htaccess wasn’t writeable by the webserver process then the hack would have failed to [...]
I haven’t tried this but don’t want to forget about it: http://infrarecorder.org/ You can also use ISORecorder which works well. Not sure of the license on this program. However the website says “Since the very beginning ISO Recorder has been a free tool (for personal use)”.

I’m fairly strict with what I allow as comments on this blog.

A browser tells the site it is visiting about itself: the plugins it is using, the screen resolution it is set at, the fonts available for display, It’s preferred language/timezone and many other little details… (OS etc) It does this in order for the remote site to be able to serve a properly formatted webpage or tailored content. The problem is, [...]
Over the last 6 years or so I’ve quite literally – according to server statistics – based out tens of thousands of e-mails on my various BlackBerry handhelds.
The BlackBerry has given me “BlackBerry thumb” in the past on the earlier thumbwheel versions. Looks like I’m hitting it back with my relatively new BlackBerry Bold 9700 giving up the ghost on its enter key.
No doubt this will be a warranty repair but I don’t know if I can be without it long enough to send it back to Telstra !

Actually got around to looking a CUDA on Nvidia cards at work yesterday.
Got the SDK and sample code up and running on the mac pro, next thing to do is find some maths problem to do on it which will be faster than on a CPU / Grid. well at least that it will be faster given a better GPU the NVIDIA GT 120 isn’t that fast considering there is 2 Xenon quad core chips 2.4ghz. on the mac then there at 6 macs connected to the Xgrid. so it will be a bit hard to do a direct comparison.
Also had a informal meeting with the lab manager from physics we discussed how that for ever increasing amount of remote courses at the university how he plans to do physics labs for the astronomy course next year.
Ended up sending him to have a look at the UTS remote labs http://remotelabs.eng.uts.edu.au/ and told him to keep us posted since it’s all of interest.
So any ideas how to show that CUDA and GPU computing is useful ? or how to conduct an astronomy lab when your students are in Queensland ?
Evolution at least the Exchange integration component is so buggy you could drive it on sand dunes. Every time I update Ubuntu I try the default mail application. For Ubuntu this is Evolution.

If you run mysqldump –all-databases you get one monolithic file which can be a pain when trying to restore one database. So it’s nice to call mysqldump dbname so you get individual database backup files. To call mysqldump for each database requires that you either hardcode the db names in your backup script, or as below, use [...]

Organisations of a certain size employ IT people and harness them into a role. Those people take on the mantel of the role, learning whatever script that has been put before them.
