socket support to NSE, with updates in scripts and libraries.
o [NSE] Added the ability to send and receive on unconnected sockets.
This can be used, for example, to receive UDP broadcasts without
using pcap. A number of scripts have been changed so that they can
work as prerule scripts to discover services by UDP broadcasting,
optionally add the discovered targets to the scanning queue:
- ms-sql-info
- upnp-info
- dns-service-discovery
The nmap.new_socket function can now optionally take a default
protocol and address family, which will be used if the socket is not
connected. There is a new nmap.sendto function to be used with
unconnected UDP sockets. [David, Patrik]
socket:connect(host.ip, port.number)
socket:connect(host.ip, port.number, port.protocol)
to this:
socket:connect(host, port)
connect can take host and port tables now, and the default protocol is
taken from the port table if possible.
