[Bug] Registering device to RPC tracker failed

[Priyadrasta-2111CS10]

Expected behavior

The output should be something like this.The picture shown below is showing the result while the RPC tracker is set on Raspberry PI and the RPC server is set on local host which in fact should be opposite.

Actual behavior

The RPC tracker couldn't track down the connected Raspberry PI as shown below.

Environment

Operating System for host : Linux 22.04 LTS
Operating System for target : Raspbian 64 bit OS

Steps to reproduce

1. Start the RPC tracker on the host system by the command python -m tvm.exec.rpc_tracker --host=0.0.0.0 --port=9190

2. Start the RPC server in the target devices by the command : python -m tvm.exec.rpc_server --tracker=[HOST_IP]:9190 --key=[KEY] .In the case of HOST_IP and KEY use your host system IP address and key for target device.

3.Track the connected devices to the current RPC tracker on your host device : python -m tvm.exec.query_rpc_tracker --host=0.0.0.0 --port=9190

I have fixed the issue. In Ubuntu 22.04 LTS ,the firewall was by default set. So we have to disable it so that the linux host can connect to RPi.In my case the command sudo ufw disable fixed the issue.
