Subject: [ruby-talk:16520] Re: forking server


Here's a stab at a forking server.  The problem is that it exits
after the first connection and I don't understand why...
Can anyone enlighten me?

thanks,

#!/usr/local/bin/ruby

require 'socket'

trap("CLD") {
  pid = Process.wait
  puts "Child pid #{pid}: terminated"
  exit
}

s = TCPServer.new("0.0.0.0",8888)
while(new_sock = s.accept)
  pid = fork
  puts "pid: #{pid.inspect}"
  if(pid == nil)
    # Child process
    # do stuff here...
    line = new_sock.gets
    line.chop!
    puts line
    new_sock.puts "you said: #{line}"
    exit
  end
end
puts "exiting... (never prints, but we do exit...)"
s.close
