Hello Cristoph, I can pragmatically confirm what Eero was saying.

The following script works fine on Win2K SP4.

C:\tmp>type sock.rb
require "socket"
Thread.abort_on_exception= true

Thread.new {
sleep 1
begin
TCPSocket.new("192.168.111.222", 1234)
rescue
end
     puts "done"
}

loop {
     puts "."
     sleep 0.25
}
C:\tmp>ruby -v sock.rb
ruby 1.8.2 (2004-11-06) [i386-mswin32]
..
..
..
..
done
..
..
..
..
..
..
..

..
sock.rb:15:in `sleep': Interrupt        from sock.rb:15
         from sock.rb:13:in `loop'
         from sock.rb:13

No hangs at all, it runs smoothly if I am disconnected from the network, 
but if I connect my address is in the form 192.168.xxx.yyy ==> 
re-executing the same script it hangs before writing "done" and then it 
writes "done" when timeout occurs (20 seconds in my case).

Ciao, Giuliano

If you want to send me an email address should be 'p', then a dot,
followed by 'bossi' at 'quinary', another dot and 'com' at last
