Install Tor, Vidalia and Polipo on Ubuntu

TOR is an anonymity solution that can be used as a proxy over the internet.

Project website
https://www.torproject.org/

Install on Ubuntu

$ sudo apt-get install tor vidalia

During the installation a configuration screen will come up, asking to select those users who would be using tor. Select the appropriate users on that page and continue. After installing the above programs start Vidalia from the gnome or kde menu (internet programs).

The tor program starts a socks server on port 9050. Vidalia is a gui for managing tor program.

Note

When starting Vidalia you might get an error message similar to

Vidalia detected that the Tor software exited unexpectedly.
Please check the message log for recent warning or error messages.

Check the message log and it would show something like this

Aug 11 12:03:45.489 [Notice] Tor v0.2.2.35 (git-73ff13ab3cc9570d). This is experimental software. Do not rely on it for strong anonymity. (Running on Linux x86_64)

If such an error occurs then tor has actually started as a daemon already. First stop it by doing

$ sudo service tor stop

Now right click vidalia icon and click "Start Tor"

If you face another error similar to this one

If such an error occurs then right click the vidalia icon in the task bar and go to

Settings > Advanced > Tor Control

and select Use TCP Connection (ControlPort)

address should be 127.0.0.1:9051

Now start Tor again and it should work.

It it still does not work then follow the post here.

Tor Browser Bundle

If you do not want to install anything then you can use the Tor Browser Bundle. It is a ready to run program that does not require any installation.

Download it from
https://www.torproject.org/

Extract all files to a directory and launch the start-tor-browser program (double click it).

It will start the Vidalia Control Panel, connect to Tor, and launch a firefox browser instance which is already configured to be anonymous.

So now you can surf anonymously!!

Polipo

Polipo is a web proxy or http proxy that can use the tor socks server. So when using the polipo web proxy with Tor the requests go like this

Browser/Application > Polipo > Tor(socks) -> Internet

whereas when using Tor socks the requests go like this

Browser/Application > Tor(socks) -> Internet

Install on ubuntu

$ sudo apt-get install polipo

After installing polipo configure it by editing the file
/etc/polipo/config

In the Basic configuration section the fields proxyAddress, proxyPort, socksParentProxy and socksProxyType need to be set to proper values

### Basic configuration
### *******************

# Uncomment one of these if you want to allow remote clients to
# connect:

# proxyAddress = "::0"        # both IPv4 and IPv6
# proxyAddress = "0.0.0.0"    # IPv4 only

proxyAddress = "127.0.0.1"
proxyPort = 8118

# If you do that, you'll want to restrict the set of hosts allowed to
# connect:

# allowedClients = "127.0.0.1, 134.157.168.57"
# allowedClients = "127.0.0.1, 134.157.168.0/24"

allowedClients = 127.0.0.1
allowedPorts = 1-65535

# Uncomment this if you want your Polipo to identify itself by
# something else than the host name:

proxyName = "localhost"

# Uncomment this if there's only one user using this instance of Polipo:

cacheIsShared = false

# Uncomment this if you want to use a parent proxy:

# parentProxy = "squid.example.org:3128"

# Uncomment this if you want to use a parent SOCKS proxy:

socksParentProxy = "localhost:9050"
socksProxyType = socks5

Once done, save the configuration file and do a service polipo restart. Now a web browser like mozilla firefox can use it.
