Ncat bugs? Server --{send,recv}-only, UDP multiple connections

Hi, I found behavior in Ncat that was surprising to me. I want to check if it's doing what it's supposed to of if these are bugs that should be fixed. The first is that --send-only and --recv-only don't appear to have any effect in server mode (--listen). With --send-only --listen I still see what's typed on the client on the server side, and with --recv-only --listen I am able to send to the client by typing in the terminal. --send-only and --recv-only work for client connections. The second is that --listen --udp quits after the first connection; it doesn't keep allowing connections like --listen --tcp does. To make a UDP qotd server I tried to do ncat -l 17 --udp --exec "/usr/games/fortune" but it quits after sending the first quote. I had to wrap it in a while loop: while true; do ncat -l 17 --udp --exec "/usr/games/fortune"; done David Fifield _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
