Installing canon canoscan lide 110 in debian squeeze

The canon canoscan lide 110  the cheapest scanner that has support in linux  as it was mentioned in sane project website but when i installed in my Debian squeeze machine it didn't even start to scan or give any sound at all; worst of all this scanner doesn't have any power on indicator LED's to let you know if it is on or off  so much for being economical :/ well anyway after searching a variety of  linux forums I  had couple of things to check whether it was working or not. The first is the scanimage command,open the terminal and type  scanimage -L 
it showed the usb id and said my device is detected and may be powered off, it was ironical considering the fact that the scanner doesn't have any indicator and asking you to check for it.The second method is to update sane drivers as the sane drivers come with squeeze is a little bit old,just download the latest sane drivers from
http://ppa.launchpad.net/stef-dev/sane-backend-genesys/ubuntu/pool/main/s/sane-backends/
just install libsane and sane-utils package  and that's it  folks you can now scan images from xsane

Installing Draftsight -part 2

This is part 2 of the series installing Draftsight  I mentioned earlier that the draftsight application will be in your graphics menu, If for some reason that the application doesn't come in the menu after installation check whether it has been installed correctly  by going to synaptic package manager and type draftsight in the filter box it will show dassault-systemes-draftsight; right click and go to properties and it will show were the files are installed then it means the application is successfully installed.Now let's create a desktop file, open  your favorite text editor and add the following  entry
[Desktop Entry]
Type=Application
Name=DraftSight
Comment=Editing CAD images
Exec="/opt/dassault-systemes/draftsight/bin/draftsight"
Icon=dassault-systemes.draftsight
Terminal=false
StartupNotify=false
and save it as draftsight.desktop when first launching the application it will ask whether to trust or not,just click  trust always and you will be having a working draftsight application in your desktop.
If you are using Xfce desktop environment right click on the desktop and goto create launcher and type application name it will show the application select it and click OK and that's it you will be having your desktop entry in seconds. 

Personal Firewall in Debian

One of  greatest and best  firewall in Linux is the IPtables firewall but it is command line and for beginners  who are conscious about online security, Iptables configuration is a very big headache atleast for me though....
after some searching I found the Firestarter firewall it is simple yet has an advanced GUI for IPtables firewall. Install from the Firestarter firewall from the repository. After installing it will be in Administration ----> Firestarter
Run firestarter and run the wizard select the dial-out device  and select
IP address is assigned via DHCP(If it is so ) and go forward disable the internet connection sharing option and go forward and in the next dialog box select
start the firewall now and you are done.It wil run in the background after you install it;Goto Edit-----> preferences to suit it to your needs.To check  whether it is running or not  go to terminal become root and run
/etc/init.d/firestarter status
it will give the following output
Firestarter is running... ... (warning).
and that's it your own personal firewall is  now operational.
