I can not get a working TCPSocket under windows with ruby 1.8.2. It just hangs. Is there currently a solution for this problem?

Hi,

I can not get a working TCPSocket under windows with ruby 1.8.2. It
just hangs. Is there currently a solution for this problem?

Could you post your code? I've used TCPSocket (and UDPSocket)
heavily under Win32 ruby since, I think version 1.6.4... Currently
running ruby 1.8.2 (2004-12-25) [i386-mswin32].

Regards,

Bill

-----------------
require 'Timeout'
require 'socket'
time =5

begin
  Timeout.timeout(time) do
    s = TCPSocket.new("google.com", "echo")
    puts "fish"
    s.close
  end
rescue Timeout::Error
      puts "Timed out"
end
----------------
I couldn't get ping.rb(stdlib) to work so I tried my own version and it doesn't work either.

Note, the above code also hangs under Linux, too. :slight_smile:

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

s.gets

s.gets

=> "\r\n"

s.gets

=> "<html><head><meta http-equiv=\"content-type\" content=\"text/html;

s.close

=> nil

HTH,
