Ok so i have downloaded backtrack 5 r2. I have tried to setup the proxy chains but when i try to open a website with this proxies i get this error:
I dont know why it timeout, but what can i do to fix it. and were can i get some more proxy server adresses like this one that is free.

Another thing: What is Konquere (web browser); yes i know it is a web browser but what is good about it. and how doe kmix work with backtrack. i have tried to run it but it starts up and then nothing? And when i try to luanch dradis on backtrack a terminal comes up, is there a gui for dradis on backtrack.
