Hello Everyone,

I'm new to NMAP. I have a curious question that I
wanted to get expert opinion on...

and ACK scans in parallel on a target generate false
results. Since same client IP is asking for opening &
closing a connection on target machine will it not

No...the TCP connections required are based on the sequence numbers

and sequence numbers. i'm not sure what's the source port generating
algorithms are used by nmap though.
