问题 ngrok's awesome web interface is pointed to http://127.0.0.1:4040 by default. I have other applications listening on that port, however, and need to change it so that ngrok listens on, say, http://127.0.0.1:4045 . 回答1: Create a config.yml wherever ngrok is looking for its default config on your platform. If the directory doesn't exist, make it (on windows this is done by entering .ngrok2. as the folder name). OS X /Users/example/.ngrok2/ngrok.yml Linux /home/example/.ngrok2/ngrok.yml Windows

问题 I've asked this question yesterday and no one was able to figure out the problem I was having. So I was hoping of providing a more up to date code with the suggestions from yesterday added on. Basically, I've been trying to form a connection between a server and a client but whenever I executed the server then the client, I'd get this exception: Address already in use . The obvious answer would be to give it a new port, but even then I still get this error. I'm assuming it has something to do

Even if I visit it on the same machine as the website is being served on. Following the advice here I have

问题 I know that bit torrent clients use automatic port forwarding (Port forwarding with having to configure the router) so that they can connect to each other. I want the users in my application to be able to host a server without having to configure the router. So I was wondering how you would do so in java? 回答1: You can use UPnP (Universal Plug and Play) port forwarding. One library mentioned is Cling, but there's much simpler library - WaifUPnP, which allows you to forward a port with just one

问题 We configured our new micro service (using Spring-Boot) in a way that the official API is on port 8080 (which is be mapped outside of our virtual network to normal HTTPS on port 443), while some management functions are on a secondary HTTP port 7979.

So we configured Spring
