use strict; use warnings; use Socket; use AnyEvent; my $udp_server my $udp_socket; sub start_udp_server { my $port = shift || 9000; my $proto = getprotobyname('udp'); my $paddr = Socket::sockaddr_in($port, Socket::INADDR_ANY); socket($udp_socket, Socket::PF_INET, Socket::SOCK_DGRAM, $proto); bind($udp_socket, $paddr); $udp_server = AE::io $udp_socket, 0, sub { my $buff; my $addr = recv($udp_socket, $buff, 256, 0); print $buff; } } start_udp_server(); my $ae_timer = AE::timer 10, 10, sub { print "timer tick\n"; } AE::cv->recv;
You can check it with nc/netcat/ncat:
ncat -u localhost 9000
