Summary: netsend udp broadcast permission denied

Initial Comment:
"connect 192.168.1.255"--[netsend 1]
  =>
connecting stream socket: Permission denied (13)


seems the default value of the socket option SO_BROADCAST has changed in recent Linux [1], so must now be set explicitly if desired.


>From "man 7 socket" on Debian/Lenny

       SO_BROADCAST
              Set or get the broadcast flag.  When enabled,  datagram  sockets
              receive packets sent to a broadcast address and they are allowed
              to send packets to a broadcast  address.   This  option  has  no
              effect on stream-oriented sockets.


depending on OS, setting SO_BROADCAST may be disallowed anyway, but as far as I can tell it does no harm to try to enable it (only affects UDP to broadcast address, does nothing for non-UDP or non-broadcast-address)

oops, i am removing this as it is about mrpeach's "udpsend" rather than
"netsend"
