Note, the above code also hangs under Linux, too. :)
I think it's just that google.com doesn't answer
connection requests on port 7 (echo).
Here's similar code (in irb on Windows) using http
instead of echo:
>> require 'socket'
=> true
>> s = TCPSocket.new("google.com", "http")
=> #<TCPSocket:0x2dc1828>
>> s.print "GET / HTTP/1.0\r\n\r\n"
=> nil
>> s.gets
=> "HTTP/1.0 200 OK\r\n"
>> s.gets
=> "Cache-Control: private\r\n"
>> s.gets
=> "Content-Type: text/html\r\n"
>> s.gets
=> "Set-Cookie: PREF=ID=5eb25ab2dffff310:TM=1109793965:LM=1109793965:

>> s.gets

>> s.gets

HTH,
