Module to query MS SQL Server Browser

ig has asked for the wisdom of the Perl Monks concerning the following question:

Is there an existing module to query MS SQL Server Browser (ms-sql-m)?

Edit: The protocol ( is simple. As I didn't find a module that provided easy access to it, I wrote my own query.

if($self->{db_server} =~ m/(.*)\\(.*)/) { my $server = $1; my $instance = $2; # This is an instance name # Resolve instance name to a port number my $socket = new IO::Socket::INET( PeerAddr => "$server:1434", Proto => 'udp', ); $socket->send("\x04$instance\x00"); eval { local $SIG{ALRM} = sub { die "Timed out waiting for recv"; + }; alarm 20; # wait up to 20 seconds for a response eval { my $ret = $socket->recv(my $data, 255); unless(defined($ret)) { die "recv error: $!"; } my ($srv_resp, $resp_data) = unpack("C n/a", $data); my $details = { split(/;/, $resp_data) }; $self->{db_host} = $details->{ServerName}; $self->{db_port} = $details->{tcp}; }; alarm 0; die $@ if($@); }; alarm 0; if($@) { die "ERROR: Query SQL Server Browser failed with: $@"; } }
