emdns is a cleverly named implementation of the multicast DNS (aka Bonjour, aka ZeroConf) and DNS-SD (DNS Service Discovery) protocols for Erlang. Eventually, it will support: http://files.multicastdns.org/draft-cheshire-dnsext-multicastdns.txt BUILD make QUICK START Assume you have two hosts "nul" and "ack". Any multicast DNS services are disabled on "nul". "ack" runs Mac OS X. Host Entry 1. Login to "ack". From a shell, run: $ ping nul.local ping: unknown host nul.local 2. On "nul", start erl: $ erl -pa ebin > emdns_server:start(). {ok,<0.35.0>} > emdns_server:debug(true). ok > A = emdns:service(host). % assumes "nul" has a reverse DNS entry <<0,0,132,...>> > emdns_server:send(A). ok 3. On "ack", run: $ ping nul.local PING nul.local (192.168.1.10): 56 data bytes 64 bytes from 192.168.1.10: icmp_seq=0 ttl=64 time=4.471 ms 64 bytes from 192.168.1.10: icmp_seq=1 ttl=64 time=2.611 ms 4. Set up a DAAP service > D = emdns:service(daap). > emdns_server:send(D). 5. On "ack", in iTunes, check "Devices" for an entry named "erlMOTE".
