Whether nc or dd is more widely used utility does not appear to be relevant to the discussion.It seemed you compared changing nc's arguments to changing dd's. dd is everywhere and as been around for a very long time. nc hasn't. That seems pretty relevant.
nc is around for about 15 years. Not old enouhg?
Out of curiosity, how many Linux distros, BSDs and anything else install *Hobbit*'s nc by default over something like OpenBSD nc?I don't know. Anyway, OpenBSD, GNU and Nmap's implementations are now *mutually* incompatible, thus claiming that old netcat is dead and buried does not help one iotaYou want compatibility with the traditional netcat and yet its rarely installed by default. When modern, incompatible netcats are installed in much greater numbers than traditional nc
They are not just incomatible with hobbit's one, they are incompatible between themselves.
, how is changing ncat going to accomplish anything?
If netcat clones will agree to not break compat gratuitously, that would be a start. My netcat clone, for one, does. Yours does not.
- the incompatibility among "modern" netcats still exists and is a problem for admins who write script using nc.Ncat isn't even named nc. That seems pretty clear to me. Anyway, wouldn't many people who script with nc be using more modern arguments since it's not the traditional netcat that's often installed?
There are no "more modern" arguments which are agreed upon. Every nc clone broke compat IN DIFFERENT WAYS.
How about a little respect towards the original author? Why not to keep stuff compatible relative to his version at least as a gesture of respect?I thought this was about script authors and usability frustration?
Yes, that is the primary reason. -- vda _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
