I'm practicing to use the ssh command with two computer on a local network. From the 192.168.102.77 machine to 10.0.2.15 machine, SSH worked well. However, the inverse is not true, i.e., from the 10.0.2.15 machine to 192.168.102.77 machine, SSH didn't work well. Honestly, I don't know how to fix this problem. Could anyone be able to tell me how to enable this access with the ssh command?

P.S. 10.0.2.15 is a VM on a MBP and 192.168.102.77 is ip address of another MBP with Ubuntu OS.

For the sudo lsof -inP, I got the following picture :

Interesting question : Do I have modify the network from VirtualBox of my VM of a certain way?
