SSH

• Installing SSH if it is not setup
  • sudo apt-get update
  • sudo apt install openssh-server
    • check for firewall
      • sudo ufw allow ssh
      • sudo ufw enable
  • sudo systemctl enable --now ssh
  • ssh username@ipaddress

sudo apt install openssh-server

sudo systemctl enable --now ssh

ssh username@ipaddress

sshremote_host

Copy

The remote_host in this example is the IP address or domain name that you are trying to connect to.

This command assumes that your username on the remote system is the same as your username on your local system.

If your username is different on the remote system, you can specify it by using this syntax:

sshremote_username@remote_host

Copy

Once you have connected to the server, you may be asked to verify your identity by providing a password. Later, we will cover how to generate keys to use instead of passwords.

To exit the ssh session and return back into your local shell session, type:

exit
