Open ssh client then insert command:
ssh username@hostname
Trouble shooting ssh connections
If you’re struggling to connect to ssh, ping the domain name or ip address:
ping [domain/ip]
IP Addresses preset in the hosts file
In some cases you may set the hosts file for a domain name and IP address. If your ssh connects to an incorrect domain/ip, look at your .hosts file and check if you are pointing your ip and domain names correctly.
