When Ncat was being developed, there was a design decision made to choose new clarity and compatibility with nmap's command line options over old compatibility to nc's command line options. If there are other things that have come up that are incompatible with nc's options (and there are other things), are we going to try to turn ncat truly into an nc clone or are we going to keep it a reimplementation in the spirit of nc. -Jason On Fri, Jan 8, 2010 at 10:32 AM, Denys Vlasenko <> wrote:
Hi, Every reimplementation of netcat seems to try to break this syntax: nc -l -p 123 # listen on local port 123 GNU nc, openbsd's nc all have it broken. And ncat is no exception. "You too, Brutus". IIRC they even break it in different ways - they have different ways to specify local port: as a parameter to -l option, as a standalone port parameter etc... AARRGGHH...
