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
