Task 2 Unit 2 - Proxychains

Proxychains - a tool that forces any TCP connection made by any given application to follow through proxy like TOR or any other SOCKS4, SOCKS5 or HTTP(S) proxy.

Proxychains is widely used by pentesters during the reconnaissance stage (For example with nmap).

We can now see, that most of the methods are under comment mark. You can read their description and decide on using one of them in the future. For this lesson let's uncomment dynamic_chain and comment others (simply put '#' to the left). Additionally, it is useful to uncomment proxy_dns in order to prevent DNS leak. Scroll through the document and see whenever you want to add some additional proxies at the bottom of the page (which is not required at this point).

Apply all the settings.

Now let's check our settings.

Start the TOR service and run proxychains firefox. Usually, you are required to put 'proxychains' command before anything in order to force it to transfer data through Tor.

service tor start
proxychains firefox

After the firefox has loaded, check if your IP address has changed with any website that provides such information. Also, try running a test on dnsleaktest.com and see if your DNS address changed too.

NOTE: All other web browser windows should be closed before opening firefox through proxychains!
