[Xymon] Querying xymond with perl socket

hello

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);

Someone can help me ?

thx

oau
