Resend the same file simultaneously with netcat in listening mode

Question

I want to set up netcat in listening mode so that many clients can connect and they all receive the same file. The clients should be able to connect simultaneously...

Is this possible?

$ nc --listen --keep-open --send-only --exec "/usr/bin/cat /path/to/myfile" 0.0.0.0 5800
$ nc 127.0.0.1 5800 > recvfile

This command sends the file only once. I'm using Ncat: Version 6.25 ( http://nmap.org/ncat ) – Zabuzzman Apr 29 '13 at 20:37
You're right. You can use the `--exec` option instead. – Spack Apr 29 '13 at 20:43
