XChat with Tor for Freenode on Backtrack 5R1

IRC scripts or invitations to run software programs, including the IRC client software, can have “malicious software” installed within. “Malicious software” not only includes Trojan horses, viruses, worms or intended and unintended backdoors, but also hardcoded messages revealing SOURCE, HOST, and other seemingly “harmless” info.

This blog article covers setting up XChat for using Tor with Freenode on Backtrack 5R1.

Change the torrc file
Install XChat
Set up a nick with Freenode
Configure XChat proxy
Configure a new server
Plug leaks
That's it!

Adding a non-root user on BackTrack 5R1

After installation of BackTrack 5 R1, there is only one user: root (or superuser). Root has full privileges in the operating system, and that makes our system more vulnerable to external attacks. A superuser can manage other user’s account, administer user data, install new applications, and configure system services and others. And of course, we can be that attacker if and when we mess up.

When installing on a hard disk and also using the system for some research and communication on occasion, we best create a non-root user with limited privileges and use su and sudo when we need more.

Installing and configuring Tor on Backtrack 5R1

Tor is free software and an open network that helps us defend against a form of network surveillance that threatens personal freedom and privacy, confidential  activities and relationships, and state security known as traffic analysis.

Privoxy "scrubs" (removes personal information from) the data it sends. But even Privoxy won't protect us from viruses, Java Script attacks, etc; and Privoxy can't do anything about text typed into forms. Stay aware, awake and alert.

Vidalia lets you start and stop Tor, see how much bandwidth you are consuming, see how many circuits you currently have active, see where these circuits are connected on a global map, view messages from Tor about its progress and current state, and let you configure your Tor client, bridge, or relay with a simple interface. Included in Vidalia is an extensive help system which helps you understand all of the options available to you.

In this blog article:

That's it for now. Enjoy!
