Hello Everyone, I'm new to NMAP. I have a curious question that I wanted to get expert opinion on... I was wondering whether running SYN, FIN, XMAS, NULL 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 render some ports open and other closed in the report?
No...the TCP connections required are based on the sequence numbers generated by the source port. each flow is identified by source port and sequence numbers. i'm not sure what's the source port generating algorithms are used by nmap though. -- Rajat Swarup http://rajatswarup.blogspot.com/ ------------------------------------------------------------------------ This list is sponsored by: Cenzic Need to secure your web apps NOW?
