Querying xymond with perl socket

I need to do a xymondboard directly with tcp. nc is working :

echo "hobbitdboard host=xxxxx test=ping" | nc xxx.xxx.xxx.xxx  1984

is working. But my perl code is not working :

#!/usr/bin/perl -w
use strict;
use IO::Socket;

$| = 1;

my $sock = new IO::Socket::INET (
                                 PeerAddr =>  'xxx.xxx.xxx.xxx',
                                 PeerPort =>  '1984',
                                 Proto    =>  'tcp',
) or warn "Cannot connect to xymon : $!\n";

print $sock "hobbitdboard host=xxxx test=ping\n";

my $answer =<$sock>;
print "$answer\n";


close ($sock);

You need to call the "shutdown" method before trying to read the data, to tell xymond that you are not going to send any more data - only then will the response come back from xymond. Something like "shutdown($sock, 1);" (1 = SHUT_WR according to my man-page).
