ncat: using UDP with --chat

[clemens fischer <ino-news () spotteswoode dnsalias org>]

Hi,

it said:

  $ ncat -u -l 9999 --chat
  Ncat: UDP mode does not support connection brokering.
  If this feature is important to you, write nmap-dev () insecure org with a
  description of how you intend to use it, as an aid to deciding how UDP
  connection brokering should work. QUITTING.

My idea is to use UDP chat mode as a kind of emergency IPC mechanism
together with "--allow" between cooperating processes on machines
without eg. posix mesage queues.

Connecting clients would tag their messages themselves, like:

  $ echo "temperature1: 33C" | ncat -u localhost 9999

Other clients would see and evaluate the entire line and respond in
a similiar way.


regards, clemens fischer
