tcp-ip

问题 I'm in a hurry at the moment. My Question is, is there a way to forward UDP to TCP port? I need this for hosting a game server for my friends, I want to host Counter-Strike server for example, but it uses UDP (User Datagram Protocol) for server port, but NGROK only supports TCP (Transmission Control Protocl) & HTTP (HyperText Transfer Protocol). I tried this while ago.. ngrok tcp 127.0.0.1:27015 and as usually it will start : ngrok by @inconshreveable (Ctrl+C to quit) Session Status online

问题 When a net.Server receives data that exceeds 1500 bytes (default mtu), the 'on data' event is executed with each fragment of the packet. Is there a way to receive the whole packet in a single 'on data' call? Thanks. 回答1: Try this var sys = require('sys'); var net = require('net');; var socktimeout = 600000; var svrport = your_port; var svr = net.createServer(function(sock) { var mdata = new Buffer(0); //sys.puts('Connected: ' + sock.remoteAddress + ':' + sock.remotePort); sock.setTimeout

问题 I have a gps device that will send packets to TCP connection hosted over web that will have a static IP address & dedicated port for it. My question is how to achieve it using WCF ? Or if WCF is needed or not for this problem. Please help me. Thanx in advance. 回答1: Did you mean TCP embedded transported/embedded using http? or just TCP but using the internet? The last is supported for sure. To set a TCP connectionover WCF is easy, just use NetTcpBinding, you can set this in C# code or better

问题 This question already has answers here : Does the port change when a server accepts a TCP connection? (3 answers) How does the socket API accept() function work? (4 answers) What is the difference between a port and a socket? (35 answers) Closed last year . This is the picture from the textbook James F. Kurose, Keith W. Ross: Computer networking: a top-down approach, ISBN-13: 978-0-13-285620-1. ISBN-10: 0-13-285620-4. According to the picture, the welcoming port is different to actual

问题 I am working on a system whereby I can update a small database from several locations. I wish to host the database on my home computer and allow connections to be made to the database from two other locations through tcp/ip. I have done the following thus far: Enabled TCP/IP for SQLEXPRESS Allowed port 1433 tcp on my firewall Allowed port 1434 udp on my firewall Enabled SQLEXPRESS server to allow remote connections I was hoping to be able to connect to the database by opening sql management

问题 How to determine what process/what executable is using, say, port 80 of my localhost? I would like to know, for example if it is Apache Server, etc. Can we get some information from ipProperties.GetActiveTcpListeners() ? I've only seen local endpoint, remote endpoint and state. 回答1: You can pipe the output of netstat -o and parse it, but that's probably a terrible idea full of headaches and edge cases. Behind the scenes, netstat -o uses the GetTcpTable2 API method from the IPHelper library,

问题 There are two C# projects: one project is for the client, the other one is for the server. First step is to run the server , then to choose a target folder, after that to run the client project, to choose some text.txt to send to the server's target folder. Only client can send files to the server Demo: 1.choosing file target 2.client sends +------------+ | tar folder | <---------------- text.txt +------------+ My problem: there isn't compile errors or syntax errors in both projects, the only

问题 What I need to do is pair with a Bluetooth enabled device which hosts some webservices and browse for DNS-SD services. Then I have to pick one of those discovered services and make some http requests over https or other secure method. I already did this trough WiFi, but for some reasons there's a need to do the same trough Bluetooth. I did some research yesterday but I haven't found what I need. I'm not sure how to approach this. Any input on this is welcomed. Thanks! 回答1: Most

问题 I am currently struggling with the following problem: I have a Java EE application that shall be able to run in a cluster (it actually does). For the data exchange between the nodes I use Hazelcast 3.3.3. Since our customers are afraid of UDP we use TCP. So I configure 3 hazelcast parameters per node: The network interface to use, the port and the members of the cluster. In real life (not a docker environment) everything works. Now I want to put my Java EE servers into docker containers (one
