I have been hired by a small company as a contractor to try to hack into their network. This is what I have so far:

Windows2000 Professional on my Laptop.

IPTools install on my laptop.

NMap install on my laptop.

I have been told to use some if not all of these tools;

WS_Ping Propack
NETScan Tools
SAM Spade
Rhino9 Pinger
Visual Route

And obviously John the Ripper as a pass cracker.

Any advice on these tools?

Any other tools recomended?

What else do I need (beside brain's)?

Thanks in advance for your help.
