Subject: Listening on UDP Sockets deos not work with recent versions of MSWin32 Perl
Install latest Perl for Windows; I tried both: - Strawberry Perl v5.26.1 - ActiveState Perl v5.22.4 (I'm only using the 32bit versions) Both of the above come with latest IO::Socket::IP version 0.39 Use the simple example posted on this PerlMonks thread: http://www.perlmonks.org/?node_id=129553 If you use IO::Socket::INET it works fine. Replace with IO::Socket::IP and it does not work anymore. In particular, what is not working is listening on UDP sockets. IO::Socket::IP seems unable to receive on UDP sockets. For some reason (which I am not able to determine), on older versions of Perl, IO::Socket::IP does work fine with UDP sockets. I have the above working fine on ActiveState v5.16.3 (32-bit version again) also with IO::Socket::IP version 0.39 Below are the simple test scripts I am using. If there is any other info I need to provide do let me know. Thanks in advance Ludovico Stevens Server script: $|++; use strict; use IO::Socket; use IO::Socket::IP; #my $server = IO::Socket::IP->new( my $server = IO::Socket::INET->new( LocalPort => 10000, Proto => "udp", # ReuseAddr => 1, ) or die "Can't create UDP server: $@"; my ($datagram,$flags); while ($server->recv($datagram,42,$flags)) { my $ipaddr = $server->peerhost; print "Oooh -- udp from $ipaddr, flags ",$flags || "none",": $datagram\n"; my $response = IO::Socket::INET->new(Proto=>"udp",PeerHost=>$ipaddr,PeerPort=>2424); $response->send("PONG!"); } Client script: $|++; use strict; use IO::Socket; use IO::Socket::IP; #my $response = IO::Socket::IP->new( my $response = IO::Socket::INET->new( Proto => "udp", LocalPort => 2424, ) or die "Can't make UDP server: $@"; #my $message = IO::Socket::IP->new( my $message = IO::Socket::INET->new( Proto => "udp", PeerPort => 10000, PeerAddr => "127.0.0.1", # PeerAddr => "127.255.255.255", ) or die "Can't make UDP socket: $@"; $message->send("Ping!"); my ($datagram,$flags); $response->recv($datagram,42,$flags); print "Got message from ", $response->peerhost,", flags ",$flags || "none",": $datagram\n";
