Port forwarding not working in android emulator

I am trying to send data to server using socket programming. The server is in android and the client is in my host machine. The program works fine and the app runs perfectly. But when I try to forward the port from host machine to emulator, it says

KO: bad redirection format, try (tcp|udp):hostport:guestport

The command I used is

redir add tcp:4000:3000

What am I missing here?

I suspect that what you have experienced is a pure typing error.

While typing commands in the Android Emulator Console, it is important to avoid typos, as the backspace does not clear the character as you would expect.

So even if the syntax of your command was correct, you must have made typing errors which you tried to clear with a backspace.

I have found the solution by myself. To be specific, I'll explain the scenario once again. I have a server socket running in android emulator, and a client in my host machine. BTW, both client and emulator runs on the same machine. I used 'localhost' to reach the server(running in emulator). And to forward the port, I used

adb forward tcp:hostport tcp:guestport

According to my example, the command will be

adb forward tcp:4000 tcp:3000
