how fast do you want to scan today?
"class A, to botnet, in under 7 minutes!."
"very fast, highly efficient, KDE free!."
"NATsmashing made trivial."
what.is.synscan?
Synscan is a(the) fast(est) asynchronous half-open TCP portscanner. This tool will send TCP packets with the SYN flag set to an arbitrary block of destination addresses. Synscan endeavours to send traffic as fast as the host network interface and kernel can support. [http://www.bindshell.net/tools/synscan]
Synscan versions <=3.9b6 were based upon version 1.6 by psychoid/tCl (http://www.psychoid.lam3rz.de), however, Synscan version 5.0 is a complete rewrite of the codebase with the following changes:
- A much, much, much, cleaner codebase!
- Vast improvements in efficiency (approximately ~20-35%)
- Fixes incorrectly computed IP header checksums (finally)
- Scan timing adjustable via command line provide for much faster network scanning
- Much simplified design will allow for future support for IPv6 (currently in beta)
