Im going to college for a computer science degree and i was advised to get used to the linux os. I did so and during this time i found out that there are pentesting courses at the college for a masters degree. I researched some linux distros and found that the new backtracks 4 is the best for, i dare say "hacking", the only problem i found was that it was heavy. My question therefore is which are the most useful programs for a student wanting to become a good professional pentester or off in that field direction. I am currently running arch linux an have found that to be my fav.
