in reply to sockets in XP activeperl

The problem is buffering - use IO::Handle's autoflush method to flush data written to the socket immediately:
use Socket; use IO::Handle; $host="www.google.com"; socket(S,PF_INET,SOCK_STREAM,0); S->autoflush(1); $s=sockaddr_in(80,inet_aton($host)); if (connect(S,$s)) { print "connected to $host\n"; print S "GET \/ HTTP\/1.0\n\n"; read(S,$data,100) || die; close(S); } else { die "connect failed\n" } print $data;
But i wouldn't use that code. Try this instead:
use strict; use Socket; use IO::Handle; my $data; my $port = 80; my $host = inet_aton('www.google.com') or die 'unkown host'; my $protocol = getprotobyname('tcp'); socket(SOCK,AF_INET,SOCK_STREAM,$protocol) or die "socket failed: $!"; my $dest_addr = sockaddr_in($port,$host); connect(SOCK,$dest_addr) or die "connect failed: $!"; print STDERR "connected to host\n"; print SOCK "GET / HTTP/1.0\n\n"; SOCK->autoflush(1); read(SOCK,$data,100); close(SOCK); print $data;
Even better - use IO::Socket:
use strict; use IO::Socket; my $data; my $port = 80; my $host = 'www.google.com'; my $socket = IO::Socket::INET->new( Proto => 'tcp', PeerAddr => $host, PeerPort => $port, ) or die "socket failed: $@"; $socket->autoflush(1); print STDERR "connected to host\n"; print $socket "GET / HTTP/1.0\n\n"; $socket->recv($data,100); print $data;
I highly recommend the book, Network Programming with Perl. Pure gold. :)
