OPEN PETA

Sometimes i wonder the power of Open Source Tools and its functionality . How the group of people are developing these much of effective software to world ? . Because forming one open source community is not so easy . Last month i was trying to find some good tools for converting video into one format to other for my Sony Ericsson Mobile Phone . I know that ffmpeg is the powerful command line tool for converting video. but the problem is using syntax of it . There are separate syntax for each and every video format conversions. i found those syntax and also i thought of finding software which is using ffmpeg in back end. Finally i got Mobile Media Converter [ MMC ] . It is a graphical interface for ffmpeg command and let allow user easily convert from one video format to other without knowing the syntax of ffmpeg. The result of converted video is as good as compared to other conversion software . You can convert the following audio and video fie format using MMC

1. Mobile Audio – AMR
2. Mobile Video –  3GP video
3. MP3 Audio [ .mp3 ]
4. Windows Media Audio
5. ogg vorbis audio
6. Wave Audio [ .wav or .au ]
7. MPEG 1/2 Video
8. AVI Video
9. Windows Media Video [ .wmv ]
10. Flash Video [ .flv ]
11. Quick Time Video
12. iPhone or iPod MP4 video [ .mp4 ]
13. PSP MP4 video

• Very simple to use for beginners also.

Demerits of MMC

Anonymous is everywhere.
Anonymous has no identity.
Anonymous is an unstoppable force.
Anonymous doesn’t fall in battle, anyway.

These are all some famous quotes about anonymous , lets get into our topic . Anonymous browsing or Proxy Surfing  is simply browsing the World Wide Web with most of your identity hidden. Proxy surfing is necessary for two cases

1. Securing Information
2. Freedom to browse all websites from Internet

Why do we need it?
Case 1 : Securing Information
If you are connected with network or Internet , your computer or network device will be assigned by one unique IP address , using that address only the computers can transfer the data from one to another and also all information might be collected such as your location , packets information, personal data. so we need to protect our data.

Case 2: Freedom to browse all websites from Internet
In college or school , Management will use proxy server to ban some websites for security purpose. Its necessary to prevent student to browse an inappropriate websites but due to this they cannot surf all the information from Internet. Some times the proxy server will block some important websites. Internet is like a universe , There would be good and bad things in it . You are the responsible person to collect the information based on your need.so freedom for browsing is needed for this case.

How to do it ?
User can install proxy software to browse all information from Internet . In our case lets take Ubuntu Linux for installing tor.  The following software are needed for proxy surfing in Ubuntu Linux Operating System .

1. tor  – The Online Router
2. privoxy -  A web based program often used with tor
3. torbutton  – Firefox add-on for tor

The tor package using socks 5 connection which is specially used for proxy server communication . You can install these packages using synaptic package manager in Ubuntu or manually download the following files and just click on it

• Libc6
• Lib Event
• Tsocks
• Tor
• privoxy
• torbutton-1.2.2-fx

After installing these packages, Just open the Firefox and enable the tor button which would be in bottom-left corner. If you are using some other browser like Opera then manually assign the Ip address in Network Option .

Tor manual IP

Finally We need to add two lines in privoxy config file . Goto  /etc/ptivoxy/config file in root mode

#sudo su

#gedit /etc/privoxy/config

In section 4.1 add the following line

Your-IP-address :8118

In my case

192.168.34.23:8118

Add the following at end of the config file

forward-socks4a / localhost:9050 .

Note : Space and dot also very important , do not mistype anything . I have attached sample configuration file for your reference

Click hete to download sample privoxy config file

Enjoy the freedom of browsing the INTERNET …..
