My first Scanner (real Open Source)

[Lynux-Penguin]

I took some source from LinuxSocket modified it, added a loop and a scanner function and took out some Constants and VOILA a scanner
note this version SUCKS UP TONS AND TONS OF MEM and Space if you don't pipe all errors to /dev/null
I need to work that out.
