The TCP Server with GUI to debug TCP connections.
If you have installed Node on your PC just run:
npx tcpsrv
Then point your browser on http://localhost:7000 to see the Web GUI.
Clients may connect using localhost:6969
address. You will see them in connections list in Web GUI. Choose any connection and then you can send and receive bytes from this connection.
Run
npx tcpsrv --help
to see available options
For testing purposes you can run a client which will be connected to the server, sends Hello!
message and then will resend all received bytes back to the server.
npx tcpsrv --echo
Be sure that you use same host/port configuration as used in server
