The best linux distrobution for learning about network security

What is the best linux distrobution for learning about network security?

I appreciate what you're asking and I'm not trying to give you a smart aleck answer. Fedora 6 is one of the better known Linux distros. A lot of people use it and like it. But there are many more distros available and based on personal preference, you might like something more than I do. I like Ubuntu. Some people like Mandriva. Some prefer Knoppix. My boss likes Puppy because he keeps it on a flash drive and takes it wherever he goes.

The point is, there are so many flavors of Linux available I can't tell you what your favorite will be. Neither can anyone else. But the great thing is, you can make your own live CDs and run them. You don't have to install them on your computer. Then you can decide what's best for you.

As I said, I prefer Ubuntu :-)
