Message: [QUOTE="P. A., post: 4654380"] Hi. I get an error when I start a WEBrick server. Here's my application. # server.rb # encoding: utf-8 require 'webrick' class Server class << self def start(config = {}) config.merge(:BindAddress => '0.0.0.0', :Port => 4321) server = WEBrick::HTTPServer.new(config) trap('INT') { server.shutdown } end end end Server.start $ ruby1.9.2dev server.rb [2009-12-08 00:21:53] INFO WEBrick 1.3.1 [2009-12-08 00:21:53] INFO ruby 1.9.2 (2009-11-14) [i686-linux] [2009-12-08 00:21:58] WARN TCPServer Error: Permission denied - bind(2) [2009-12-08 00:21:58] WARN TCPServer Error: Permission denied - bind(2) /opt/ruby-1.9.2-dev/lib/ruby/1.9.1/webrick/utils.rb:73:in `initialize': Permission denied - bind(2) (Errno::EACCES) from /opt/ruby-1.9.2-dev/lib/ruby/1.9.1/webrick/utils.rb:73:in `new' from /opt/ruby-1.9.2-dev/lib/ruby/1.9.1/webrick/utils.rb:73:in `block in create_listeners' from /opt/ruby-1.9.2-dev/lib/ruby/1.9.1/webrick/utils.rb:70:in `each' from /opt/ruby-1.9.2-dev/lib/ruby/1.9.1/webrick/utils.rb:70:in `create_listeners' from /opt/ruby-1.9.2-dev/lib/ruby/1.9.1/webrick/server.rb:74:in `listen' from /opt/ruby-1.9.2-dev/lib/ruby/1.9.1/webrick/server.rb:62:in `initialize' from /opt/ruby-1.9.2-dev/lib/ruby/1.9.1/webrick/httpserver.rb:24:in `initialize' from server.rb:24:in `new' from server.rb:24:in `start' from server.rb:31:in `<main>' When I start it as a root I get another error. # ruby1.9.2dev server.rb [2009-12-08 00:26:18] INFO WEBrick 1.3.1 [2009-12-08 00:26:18] INFO ruby 1.9.2 (2009-11-14) [i686-linux] [2009-12-08 00:26:23] WARN TCPServer Error: Address already in use - bind(2) I also get these errors while I use a stable version of Ruby (1.9.1). I haven't got any other applications working on port 4321. Debian GNU/Linux 5.0.3; Ruby 1.9.1, 1.9.2dev; WEBrick 1.3.1. What is the reason of this bug? Thanks. [/QUOTE]
