That's a good idea. In svn://svn.insecure.org/nmap-exp/david/nmap-listen
I added -k/--keep-open like you suggested. -k doesn't conflict with any
nc or GNU Netcat options. However, I see that a Windows version of
Netcat uses -L ("listen harder") for much the same feature.

There was a request for -L in Ncat, and Kris pointed out that -l already
does that.

http://seclists.org/nmap-dev/2009/q1/0037.html

But because persistent connections cause some programs to lose the tail
end of transfers, we're thinking of making non-persistent the default. I
think the ncat-listen branch does what we need, but it remains to choose
the user interface. I like -k/--keep-open, but -L (and maybe --Listen?)
has the benefit of a precedent. Does anyone have a preference?


I'm confused: Daniel said in his initial post that the -k option in his patch
is like the same option from BSD netcat.  So -k has precedent too, right?

But either way, I prefer -k to -L.
