[en] Yet Another TCP Scanner
I wrote a new TCP scanner, at last.
- It was easy.
- It is simple (less than two pages of C)
- It is quick, even against a firewalled machine
- It grabs banners, and save times for the service identification phases later.

Nowadays kernels aren't anymore bent by scarce hardware resources and the necessity to keep them available in userland. As far as I can guess, no architecture provides efficient multi-leveled privilege isolation, and no operating system paradigm more complex than Unix emerged from the swamp. Security being a serious matter in the IPv4 world, while TCP's being used as ordinary, asynchronous I/O, a rich kernel becomes a powerfull, fast & secure service provider for userland processes. Userland API aren't usefull if you use a langage using the same calling conventions than your kernel (C).
Show us the source !
