I was able to connect to my xubuntu system installed in a virtual box via ssh from my PC (running Ubuntu 16.04):
Later, in the same machine (xubuntu) I executed the following commands to enable FTP access:
sudo ufw disable sudo iptables -F
Now I cannot connect to it via ssh, I get the following error:
ssh: connect to host 192.168.8.103 port 22: Connection timed out
How can I solve this issue?
