DNS-SD Gem (0.6.0) on OSX Leopard 10.5.3

Hi All,

I am attempting to use the DNS-SD gem to return information about bonjour on Leopard. When I use the command line tool with the command "$ dns-sd -B _sftp-ssh._tcp" I get the following response:

Browsing for _sftp-ssh._tcp
Timestamp A/R Flags if Domain Service Type Instance Name
8:34:04.871 Add 3 5 local. _sftp-ssh._tcp. DL Office Desktop
8:34:04.872 Add 3 9 local. _sftp-ssh._tcp. DL Office Desktop
8:34:04.872 Add 3 10 local. _sftp-ssh._tcp. DL Office Desktop
8:34:04.872 Add 3 7 local. _sftp-ssh._tcp. DL Office Desktop
8:34:04.872 Add 2 8 local. _sftp-ssh._tcp. DL Office Desktop

However, when I run the following I get no response back:

#!/usr/bin/env ruby -wKU

require 'rubygems'
require 'dnssd'

DNSSD.browse("_sftp-ss._tcp") do |browse_reply|
  puts browse_reply
end

I am using ruby 1.8.6 on Leopard 10.5.3 with dnssd-0.6.0 (ruby and the gem were part of the standard Leopard install). My ultimate goal will be to browse for DNSSD services and then resolve a particular service.

Thank you in advance for any help you might be able to render.

Hi All,

I was in error in my last email. In fact, DNSSD.browse is returning the result as expect. instead, DNSSD.resolve is not returning any response when the [ dns-sd -L "Denis's MacBook Air" _ssh._tcp local ] command line tool returns the response as expected.

Here is the commandline response:

···

_____
Don-Levan-x-392:~ donl$ dns-sd -L "Denis's MacBook Air" _ssh._tcp local
Lookup Denis's MacBook Air._ssh._tcp.local
11:04:13.345 Denis's\032MacBook\032Air._ssh._tcp.local. can be reached at Deniss-MacBook-Air.local.:22

Here is what my script looks like:
________

#!/usr/bin/env ruby -wKU

require 'rubygems'
require 'dnssd'

class DNSResolver

   def resolve
     puts "resolving"

     resolver = DNSSD.resolve("Denis's MacBook Air", "_ssh._tcp", "local") do |resolve_reply|
       puts "Resolve Result: #{resolve_reply.inspect}"
     end

     puts "Resolver Started"
     sleep 30
     resolver.stop
     puts "Resolver Stopped"

   end

end

resolve_reply = DNSResolver.new.resolve
_____

This is the response from I get in textmate:
_________

RubyMate r8136 running Ruby r1.8.6 (/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby) >>> dnssdbrowse.rb
resolving
Resolver Started
Resolver Stopped
Program exited.

Thanks again for any help.
