Question: How do I install Tor (The Onion Router) software under Debian / Ubuntu Linux? How do I communicate anonymously on the Internet? How do I anonymously browser the Internet so that I can avoid network surveillance that threatens personal freedom and privacy under Linux operating systems?
Answer: Onion routing is a system enabling its users to communicate anonymously on the Internet. You need to install following softwares:
WARNING! These examples and faq is about anonymity and not about security. Tor can be easily used to see sensitive data by exit nodes. Do not mistake Tor’s anonymity for security.Install tor and privoxy
Type the following command as root user or use sudo command:
$ sudo apt-get install tor privoxy
Linux tor and privoxy configuration
By default tor listen on TCP port # 9050. Open /etc/privoxy/config file, enter:
$ sudo vi /etc/privoxy/config
Append / change following config directive to chain Privoxy and Tor, both running on the same system:
forward-socks4a / 127.0.0.1:9050 .
Save and close the file. Restart privoxy:
$ sudo /etc/init.d/privoxy restart
Sample privoxy config file
See man page for detailed information (above configuration is sufficient to get started with tor)
# Generally, this file goes in /etc/privoxy/config forward-socks4a / 127.0.0.1:9050 . confdir /etc/privoxy logdir /var/log/privoxy actionsfile standard actionsfile default actionsfile user filterfile default.filter debug 4096 debug 8192 user-manual /usr/share/doc/privoxy/user-manual listen-address 127.0.0.1:8118 toggle 1 enable-remote-toggle 0 enable-edit-actions 0 enable-remote-http-toggle 0 buffer-limit 4096
Configure browser for tor
Open Firefox click on Edit > Preferences > Advance tab > Settings:
Fig.01: Tor with Firefox network settings
Set 127.0.0.1 and 8118 as privoxy server IP and port number. Now Firefox is ready to use with Tor.
Firefox Torbutton plugin
You can also install Torbutton plugin, for best safety. Simply grab and install the Torbutton plugin, restart your Firefox, and you’re all set to use Tor. From the project page:
Torbutton provides a button to securely and easily enable or disable the browser’s use of Tor. It is currently the only addon that will safely manage your Tor browsing to prevent IP address leakage, cookie leakage, and general privacy attacks.

one word for ya
TOR
Can someone please explain: “Tor can be easily used to see sensitive data by exit nodes”?
Thanks,
@T,
In September 2007, Dan Egerstad, a Swedish security consultant, revealed that by operating and monitoring Tor exit nodes he had intercepted usernames and passwords for a large number of email accounts.[15] As Tor does not, and by design cannot, encrypt the traffic between an exit node and the target server, any exit node is in a position to capture any traffic passing through it which does not use end-to-end encryption, e.g. SSL. While this does not inherently violate the anonymity of the source, it affords added opportunities for data interception by self-selected third parties, greatly increasing the risk of exposure of sensitive data by users who are careless or who mistake Tor’s anonymity for security.

Thank you kindly for the info
if net is via proxy , username:password
then?
Tor is slow as fackkk….. I would not recommend using Tor to anyone. Slows down your connected to a crawl. Worse than dialup. I tried and it was horrible. DO NOT Use this.
# Updated sample config file, first do these two commands:
