DESCRIPTION

This module is an extension to NetworkInfo::Discovery which can find services that register themselves using DNS-SD (DNS Service Discovery), the services discovery protocol behind Apple Rendezvous.

It will first try to enumerate all the registered services by querying the dns-sd pseudo-service, which is available since the latest versions of mDNSResponder. If nothing is returned, it will then query some well-known services like afpovertcp.

METHODS

new()

Creates and returns a new NetworkInfo::Discovery::Rendezvous object, which derives from NetworkInfo::Discovery::Detect.

Options

• domain - expects a scalar or an arrayref of domains

Example

    # specify one domain
    my $scanner = new NetworkInfo::Discovery::Rendezvous domain => 'example.net';

    # specify several domains
    my $scanner = new NetworkInfo::Discovery::Rendezvous domain => [ qw(local example.net) ];

do_it()

Run the services discovery.

get_services()

Returns the list of discovered services.

discover_service()

Discover instances of a given service.

domain()

Add domains to the search list.

Examples

    $scanner->domain('zeroconf.org');
