问题 I have en ELB with multiple EC2 instances registered in target groups. I am using port a php application which is running properly. It has SSL. I want to use port 8000 for my node application.

问题 I've got a SQL Server 2000 box that I'd like to put on "the Internet" so that developers could connect remotely without VPN access. What's the safest way to do so? It might be temporary, e.g. every once in a while, but it's definitely necessary. Thanks, Rob 回答1: Short answer - don't do this. Long answer: Install good firewall on the box. Install and run ssh server on it. Open only the ssh port. Your devs can use PuTTY or any other ssh client to "tunnel" the sql port over the ssh connection.

问题 I have multiple instances of Rails servers and there is a need for each one of them to know its own listening port in environment.rb. request.port will work in the controllers but not in the context of the environment.rb. Is there a way? Thanks! 回答1: You can get the running rails port using this code: Rails::Server.new.options[:Port] You can take a look at the options parser in the Rails documentation to see what hash parameters are available. 来源： https://stackoverflow.com/questions/9574129

问题 Is there a way to get, in the test, the port in which the rails app is running during cucumber test? I tried Capybara.server_port but that's nil. Thanks. 回答1: When using the selenium driver, the port can be found on: Capybara.current_session.driver.rack_server.port and when using the webkit driver, it can be found on: Capybara.current_session.driver.server_port Alternative, you can set Capybara.server_port to a known value and use that. 回答2: My understanding is that if you're using rack-test,

问题 I am doing direct I/O on a parallel port which is fine and necessary for speed. I would like to enumerate the available ports to offer the user a choice of ports at setup time rather than a tedious trawl through device manager to read the address manually. Does anyone know a means of doing this please? Many thanks, Brian 回答1: According to this Microsoft article, for Win2K and newer, you can find details of parallel-connected devices in the registry at HKLM\SYSTEM\CurrentControlSet\Enum
