Windows Machine: Need to kill a Node.js server, and you don’t have any other Node processes running, you can tell your machine to kill all processes named node.exe. That would look like this: taskkill /im node.exe And if the processes still persist, you can force the processes to terminate by adding the /f flag: taskkill … Read more
A single listening port can accept more than one connection simultaneously. There is a ’64K’ limit that is often cited, but that is per client per server port, and needs clarifying. Each TCP/IP packet has basically four fields for addressing. These are: source_ip source_port destination_ip destination_port <—– client ——> <——— server ————> Inside the TCP … Read more
Find out the process ID (PID) which is occupying the port number (e.g., 5955) you would like to free sudo lsof -i :5955 Kill the process which is currently using the port using its PID sudo kill -9 PID
You can access your host machine with the IP address “10.0.2.2“. This has been designed in this way by the Android team. So your webserver can perfectly run at localhost and from your Android app you can access it via “http://10.0.2.2:<hostport>“. If your emulator must access the internet through a proxy server, you can configure … Read more
You can search on how to kill that process. For Linux/Mac OS search (sudo) run this in the terminal: $ lsof -i tcp:3000 $ kill -9 PID On Windows: netstat -ano | findstr :3000 tskill typeyourPIDhere change tskill for taskkill in git bash
1- Stop other applications that are using port 80. 2- run application with port 80 : if __name__ == ‘__main__’: app.run(host=”0.0.0.0″, port=80)
Here is the easy solution of port finding… In cmd: netstat -na | find “8080” In bash: netstat -na | grep “8080” In PowerShell: netstat -na | Select-String “8080”
The answer differs depending on what OS is being considered. In general though: For TCP, no. You can only have one application listening on the same port at one time. Now if you had 2 network cards, you could have one application listen on the first IP and the second one on the second IP … Read more
As pointed by B. Rhodes, nc (netcat) will do the job. A more compact way to use it: nc -z <host> <port> That way nc will only check if the port is open, exiting with 0 on success, 1 on failure. For a quick interactive check (with a 5 seconds timeout): nc -z -v -w5 … Read more
Use this command to find your active zone(s): firewall-cmd –get-active-zones It will say either public, dmz, or something else. You should only apply to the zones required. In the case of public try: firewall-cmd –zone=public –add-port=2888/tcp –permanent Then remember to reload the firewall for changes to take effect. firewall-cmd –reload Otherwise, substitute public for your … Read more
