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

Resolver Stopped  
Program exited.

Thanks again for any help.
