python broadcast socket

[Guest]

I'm sort of new to both Python and socket programming so I appologize ahead of time if this is a dumb question. I have found that the following code works on windows but on linux I get an exception.

import socket
s = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
s.connect( ( '<broadcast>', 1617 ) )

The exception I get is:

socket.error: (13, 'permission denied')


I have tried this on three Linux machines. All firewall software is disabled.


Thanks for you time and patience.

Sending broadcast packets is a dangerous thing and not
something a normal user should be able to do. In a real OS,
it's a restricted operation and you need special privledges.

Under Linux, you need to be root to send a broadcase packet.

Under Linux, you need to be root to send a broadcase packet.

I don't think this is true.
