Linux Toolkit - A Tool 2 Cool 4 U Linux Toolbox Back to Contents Ah, the Linux Toolbox. Remember the Acme Toolkit? nc (netcat) Yup, the ol' tried and true swiss army knife of networking - netcat. cryptcat Well, improving upon netcat we have cryptcat. stunnel Very similar to netcat and cryptcat, but stunnel uses SSL to encrypt the data.

Firewalk Firewalk is a useful tool for assisting in the determination of ACLs on network gateways and in mapping networks. hping A very cool TCP/IP packet assembler & analyzer. HUNT HUNT is another questionable tool. nemesis Nemesis is a tool useful for pen-testing as well as a low level learning aid. Nessus Nessus is one of my personal very favorite open source tools. . . . . . . . . . . . . . . . .

Don’t worry if you aren’t a scripting master, I’m going to take it slow through this series so that you can absorb what’s going on. The Basics You need access to a Linux system and last week’s post, “Scripting, Part One”. The Lively Loop There’s nothing particularly special about a loop. My original example is a good one. First, look at what’s needed to make this happen: a list of users, the file in question, and, depending on the file’s purpose, an optional permissions change. #! #! root@aspen:~# . #!
