Hi all,

I need to concentrate 20 UDP data stream, i.e. I receive data on 20
UDP ports, and I need a single (tunneled TCP) output stream.

I tried using netcat with a port range as follows:

netcat -u -l -n -vv -p 5000-5019 | netcat -vv -n 8000

to capture all data from port 5000-5019 and pipe it for further

However, it seems as if netcat only waits for input on the first
(available?) port in the range.

Is this expected behaviour or am I doing something wrong?

I can, of course, hack my own script, but netcat seemed to be so
simple and elegant ;-)

Thanks for any feedback!
