Create USB Live distros with UnetBootin

9 08 2008

A couple of days ago in the attempt to install Hardy Heron on an Asus EEE 4G, i needed to create an live usb pendrive , since the computer itself has no cd slots.

There are many resources online on how to do this. Most part of them failed with a Grub error of some sort, perhaps also due to the EEE skittish attitude ;).

Then i came across Unetbootin.Site link

Hardy On Acer Aspire 3680

9 08 2008

Today did an installation of Ubuntu 8.04 on an Acer Aspire 3680, which up until this point was used as a Windows machine.

Turns out this model too has the Atheros AR5007EG (AR242x ) installed.
The same as the Aspire 5315.

In previous post i had described a fix for this card using ndiswrapper.
The same instructions are valid this time too.

Here’s the link : /hardy-on-acer-aspire-5315/





Video Surveillance system on Ubuntu 8.04 with Zoneminder

4 08 2008

In this scenario we will be using:

Hardy Heron ( Ubuntu 8.04 )
Packard Bell Easynote R0933
ZoneMinder 1.22.3 website
Panasonic BL-C1 network cameras

It is assumed that the machine is a fully working Lamp server.
If you don’t have that yet, here’s a quick setup.

First we need to install a few libraries to support Zoneminder :

sudo apt-get install libarchive-tar-perl libmime-perl libstdc++6 libjpeg62 ffmpeg
libarchive-zip-perl zlib1g libdate-manip-perl libwww-perl libdevice-serialport-perl

Afterwards, we grab the latest .deb from the repositories
http://packages.ubuntu.com/hardy/net/zoneminder

Enable Remote Desktop on Ubuntu from command line

3 08 2008


On some of the workstations i happen to use, at times it’s neccessary to have Remote Desktop enabled.
Here’s a quick and dirty way to turn it on and off.

sudo gconftool-2 -s -t bool /desktop/gnome/remote_access/enabled true

To disable it set it to false.

In a similar way you can enable disable the confirmation request:

gconftool-2 -s -t bool /desktop/gnome/remote_access/prompt_enabled false





LAMP ( Linux, Apache, MySql, Php ) Server on Ubuntu 8.04

3 08 2008


In a post, a few days ago, i described how i had to restore and reinstall my system.
Meaning daily, i’ve been finding some of the software i need and reinstalling it.

So here i found myself needing to make use of a Lamp server on my laptop.
There’s literally thousands of guides about how to achieve this. Fact is that, on Ubuntu 8.04 (Hardy Heron ), it can be reduced to a few easy steps, and all the trick is done.

Once more, for the sake of clarity, and to spare some time:

Install mysql
sudo apt-get install mysql-server-5.0

Install Apache2
sudo apt-get install apache2

Install php and the apache module for it
sudo apt-get install php5 libapache2-mod-php5

Reboot apache (very important)
sudo /etc/init.d/apache2 restart

PhpMyAdmin, if you need it
sudo apt-get install phpmyadmin

That’s all folks!





Removing Bios Hardware Password and Boot Block on Acer Aspire 1360

28 07 2008

Sometimes laptops while still on factory settings have a default password that protects the BIOS and at times even the booting of the machine itself.

If ever in this situation you can send the hardware in one of the maintenance labs , and they will very nicely sort it out for you. The problem is that this costs 75-100 euros + time.

The protection actually is created by a hardware switch ( otherwise they could just tell you the pass right ).

Not too long ago i had to do something of than nature with and acer Aspire 1360.
Took a few pics in the process too , to document it better.

Using Python for Symbian from Windows XP through Bluetooth

24 07 2008

Everyday I seem to find more and more ways to play with my E61i.

Python is a extremely powerful language , wich is finding everyday more and more ways to apply itself to the mobile world.

So this is how you would go on about pairing your S60 phone with Windows XP.

The hardware used is Nokia E61i (S60 3rd), Dikom Bluetooth USB dongle, Easynote R0933 with Windows XP on it.

Fixing GRUB after Windows install

23 07 2008

For me it’s a fact by now. Every time i decide to install WinXP back onto my laptop, something goes wrong. Big time.

After creating a 25 GB partition on my laptop i proceeded into installing Windows Xp Sp2 (which the laptop had preinstalled anyways when i got it).
The installation went smooth enough and as expected the MBR is messed up at this point and the computer boots directly into Windows.

As done a few times before, but still worth mentioning, the procedure in these cases is:

1. Boot the Live CD
2. Open a terminal window and type:

sudo grub

3. On the new prompt:

grub>> find /boot/grub/stage1
the answer in my case (hd0, 0)

4. Proceed

root (hd0,0)
setup (hd0)

Using your phone as a remote control for your Ubuntu computer, via Bluetooth

19 07 2008

I literally mean that.

The idea popped in my head a few days ago and i thought it would be quite interesting to see how doable it was.

The hardware used is a Dikom (Broadcom) Usb bluetooth dongle, a Nokia E61i ( Symbian S60 3rd ) and tested on a Dell Inspiron C521 and a PackardBell Easynote R ( both on Hardy Heron 8.04).
It is also assumed that the dongle is connected and the computer can use bluetooth normally.

So looking around for projects that had already done this, i came across three main ones.

Dual Screen for Dell Latitude on Hardy Heron

4 07 2008

Few days back i refound in the office this Dell Latitude laptop (with a german keyboard layout) that
we simply were not using in a while. It was running XP and not too well either.

So wanting to make some use of it for some mobile task i decided to wipe it an place 8.04 on it.

The installation went fine. Actually even a US Robotics Wireless PCI card was working right out of the box. Following the true Ubuntu spirit.

The only thing i was unable to do from the GUIs was configuring the 2nd screen.
Then let’s attempt another approach .
