问题 I know how to connect a client to a server, world-wide! check this link if you want to have a quick code to workout: http://cs.lmu.edu/~ray/notes/javanetexamples/ My question is "how can I connect two clients without the server?" The server might be there to listen to clients, but once they connected, I want the server out of the deal and then clients can talk directly. My server is in U.S., client A is in Europe and client B is in Asia. Clients are regular users and they just run the app and

问题 I'm trying to read the data from HTTP stream with TCP inside Linux kernel. I'm able to get most data from skb_buff here. However, if the server pushes data to the client without requests, the data won't be copied to user space so that I cannot find it any more. Using Wireshark, I can find the additional data as a single packet normally. Therefore I think these data should go into kernel somewhere, even if they are not requested by the user space. Is it possible to find all the data when they

问题 I want to get server sockets working for HTTP/2 in Java, preferably TLS/https. I've got a TLS server socket working fine, but browsers will only talk HTTP/1.1 to it. If I understand correctly, you need ALPN to get a HTTP/2 browser to connect to your TLS socket and start running HTTP/2 on it; browsers won't ask for upgrade to HTTP/2 on https. It seems Java8 does not do ALPN so far. Maybe there is some other way to coerce browsers to do HTTP/2, at least non-TLS. So, anybody know how to make a

问题 What's the difference between creating a server using http module and creating a server using express framework in node js? Thanks. 回答1: Ultimately, express uses node's http api behind the scenes. express framework The express framework provides an abstraction layer above the vanilla http module to make handling web traffic and APIs a little easier. There's also tons of middleware available for express (and express-like) frameworks to complete common tasks such as: CORS, XSRF, POST parsing,

问题 How to host angular 2 website? I am new to angular 2 and I made a simple website with no back-end. I wondered that when I tried to open directly index.html file, it opens with error. But after command "npm start" it works fine, which runs a local server on computer. So, how to host this website on simple hosting sites (Not a Dedicated Server..!)? I think hosting sites automatically find index.html file, but here is the problem, index.html is don't start without "npm start" command. can I have

问题 I followed DigitalOcean's tutorials on how to set up your server with SSH, creating a new user, firewalls etc. The first tutorial in the series is linked under: https://www.digitalocean.com/community/tutorials/how-to-connect-to-your-droplet-with-ssh I've also installed Webmin on my server, but I still can't get a connection to the server by using the web-browser. It just loads for a long time and then says it can't establish a connection. The URL's I've been using are: "Just-my-IP-adress" and

问题 I am trying to send a Push notification to my android device with the new Firebase service. I registered and setup an app, also I put all the code needed to receive notification in the android app. Via the Firebase Console I can send a notification to my app and it is received and shown. Now I want to write a java standalone server, to send a notification to ALL devices. This is my current code: final String apiKey = "I added my key here"; URL url = new URL("https://fcm.googleapis.com/fcm
