ssh no route to host port 22

Are there anyone previously solving the problem in attachment?

ssh no route to host port 22

How are the host and Jetson connected, e.g., via a network switch versus router? Direct ethernet crossover cable?

Does host have any firewall going?

A router, a network cable for host and a network cable for jetson.

i have Firewall adjustment in second attachment.

What is the output of “ifconfig” on host? Is the the Jetson? Do you have a way to verify if the Jetson booted?
