@proxx, the reason it's unstable is because it's not intended to be used as an OS that you would browse facebook with. It comes pre-installed with a lot of additional services that take barely any configuring to setup (like an ssh, ftp, tftp, and http server). Ofc it's going to be vulnerable to a lot of different things. It's designed to be setup as quickly as possible, so you can fuck shit up as quickly as possible.

@everyone else, Backtrack is extremely useful for the sole purpose of cracking. That's all it is supposed to do. It is supposed to help a semi-knowledgeable person get shell on as many different machines, as fast as technologically feasible. All of this ranting about how much it sucks isn't going to get you anywhere.
If I want to cross-compile a windows exploit on linux, and successfully get a shell from a vulnerable service, I can do that with backtrack. If I want to setup a web server, and host client-side exploits, I can do that with backtrack. If I need to reverse ssh tunnel a vulnerable service behind a firewall on a target back to me, I can do that with backtrack. I'm not saying you can't do it on any other distro. What I am saying is that you can do all of this, and more with backtrack as it is, without having to download/compile/make/configure/trouble-shoot whatever I need to do a task necessary for getting a shell/other valuable credential.
It's great if some of you want to create/find your own tools, but please don't knock backtrack off as useless just because it's "mainstream"
