</div>

on:

$ sudo webrick\_test.rb

where webrick\_test.rb reads:

#!/usr/local/bin/ruby

require ‘webrick’

PORT = 8809  
DOCUMENT\_ROOT = Dir.pwd

s = WEBrick::HTTPServer.new :port =\> PORT, :DocumentRoot =\>  
DOCUMENT\_ROOT

trap(‘INT’) { s.shutdown }

s.start

no matter what port i use i get this:

[2006-05-24 18:07:16] INFO WEBrick 1.3.1

</div>

incidentally i have no such errors when i use TCPServer

require ‘socket’

port = (ARGV[0] || 8808).to\_i  
server = TCPServer.new(‘localhost’, port)  
while session = server.accept  
req = session.gets  
puts “Request: #{req}”  
session.print “HTTP/1.1 200/OK\r\nContent-type: text/html\r\n\r\n”  
session.print “

# #{req}
”  
session.close  
end
