I wonder if anyone can help me make sense of this packet trace. It shows nmap running a connect scan against port 13 of a host. The part I don't understand is why there are 3 RST packets sent to the target machine?
It looks as if nmap is sending RST packets until it receives a FIN packet from the portscanned machine. What options do you use with nmap to obtain this traffic?
If it helps anyone the target host is a Debian box running 2.4.26 Linux kernel and the source machine was a RedHat box running 2.4.7-10. The version of nmap used is 3.48. Cheers Rich.
