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)
