How do I use raw sockets in Perl?

Question

How can you get a raw socket in Perl, and then what's the best way to built a packet for use with it?

Answer 1

The same way you do in C... by setting the socket type when creating the socket.

In the example on CPAN use SOCK_RAW rather than SOCK_DGRAM (UDP) or SOCK_STREAM (TCP).

NOTE: creating raw sockets typically requires administrative privileges (i.e. root on UNIX). Windows OS's may have disabled ability to create raw sockets, you'll just have to test it and see.
