Simple UDP Transfer Utility

[SMurf]

Hello,

I could do this myself, but to save myself a day or so, is anyone aware of a utility that can be used to send/recv binary data to a specific address : port via UDP?

It would be sort of like an interactive version of Wireshark.

It shouldn't take you that long; all you need is something that takes an address and port on the command line, then reads from stdin so you can pipe data into it. In C, that's <50 lines, and it looks like Boost::asio will simplify that in C++:

TCP, UDP and ICMP - Boost 1.38.0

Or if you have perl:

#!/usr/bin/perl
use strict;
use warnings FATAL => ('all');

use IO::Socket::INET;

my $sock = IO::Socket::INET->new (
	PeerAddr => $ARGV[0],
	PeerPort => $ARGV[1],
	Proto => 'udp'
);

$sock->send($_, 0) while (<STDIN>);

Usage, eg:

./udpsend.pl localhost 1313 < somedata.bin
