"Real" half open request

[chris576]

Hello there.

Its not a real issue, but since I would like to implement my own golang based network scanner, I wish to adjoin discussion about scilent port scans.

From my point of view, a scilent, half-open port scan, cuts the connection after receiving the SYN-ACK Flag package. Therefore, no real connection is established to the host and the port scan is actual a lot harder to detect.

You had implemented your port scan with the net package and the connectTimeout Function. As I understood, this establishes a real TCP connection. It's a lot easier to implement, but my ambition is thrilled: Is it also possible in go, to implement a real hald-open port scan?

I do some more research and maybe in closer future, I get an answer.
