I'm trying to test UDP broadcasts and am using this command:
$ echo "Hello World" | sudo nc -v -u 10.1.0.255 12000
nc: connect to 10.1.0.255 port 12000 (udp) failed: Permission denied
I have sudo access so I'm wondering how I can correct the permission denied error so that I can send UDP broadcasts.
The error doesn't seem to imply that you haven't permissions on your source systems. It seems to say that you haven't permissions on the destination system. Is the port closed in the firewall of the destination system for instance?
12000 doesn't seem to be a standard port for any service. It doesn't show in the list here: http://en.wikipedia.org/wiki/ListofTCPandUDPportnumbers
@FranciscoD_ you can check the port numbers at /etc/services
