NAME
Net::Bonjour::Entry - Support module for mDNS service discovery (Apple's Bonjour)
SYNOPSIS
use Net::Bonjour; my $res = Net::Bonjour->new(<service>[, <protocol>]); $res->discover; foreach my $entry ( $res->entries ) { print $entry->name, "\n"; }
DESCRIPTION
Net::Bonjour::Entry is a module used to manage entries returned by a mDNS service discovery (Apple's Bonjour). See Net::Bonjour for more information.
METHODS
new([<fqdn>]) Creates a new Net::Bonjour::Entry object. The optional argument defines the fully qualifed domain name (FQDN) of the entry. Normal usage of the Net::Bonjour module will not require the construction of Net::Bonjour::Entry objects, as they are automatically created during the discovery process. address Returns the IP address of the entry. all_attrs Returns all the current attributes in the form of hashed array. attribute(<attribute>) Returns the specified attribute from the TXT record of the entry. TXT records are used to specify additional information, e.g. path for http. dnsrr([<record type>]) Returns an DNS answer packet of the entry. The output will be in the format of a Net::DNS::Packet object. The record type designates the resource record to answer with, i.e. PTR, SRV, or TXT. The default is PTR. fetch Reloads the information for the entry via mDNS. fqdn Returns the fully qualifed domain name (FQDN) of entry. An example FQDN is server._afpovertcp._tcp.local hostname Returns the hostname of the server, e.g. 'server.local'. name Returns the name of the entry. In the case of the fqdn example, the name would be 'server'. This name may not be the hostname of the server. For example, names for presence/tcp will be the name of the user and http/tcp will be title of the web resource. port Returns the TCP or UDP port of the entry. sockaddr Returns the binary socket address for the resource and can be used directly to bind() sockets.
EXAMPLES
Print out a list of local websites print "<HTML><TITLE>Local Websites</TITLE>"; use Net::Bonjour; my $res = Net::Bonjour->new('http'); $res->discover; foreach my $entry ( $res->entries) { printf "<A HREF='http://%s%s'>%s</A><BR>", $entry->address, $entry->attribute('path'), $entry->name; } print "</HTML>"; Find a service and connect to it use Net::Bonjour; my $res = Net::Bonjour->new('custom'); $res->discover; my $entry = $res->shift_entry; socket SOCK, PF_INET, SOCK_STREAM, scalar(getprotobyname('tcp')); connect SOCK, $entry->sockaddr; print SOCK "Send a message to the service"; while ($line = <SOCK>) { print $line; } close SOCK;
