How to Install SSH Server

20.57.00 Dilan Deswara 2 Comments

sudo apt install openssh-client

sudo apt install openssh-server

man sshd_config

To set your OpenSSH to listen on TCP port 2222 instead of the default TCP port 22, change the Port directive as such:

Port 2222
To have sshd allow public key-based login credentials, simply add or modify the line:

PubkeyAuthentication yes

If the line is already present, then ensure it is not commented out.
To make your OpenSSH server display the contents of the /etc/issue.net file as a pre-login banner, simply add or modify the line:

Banner /etc/issue.net

In the /etc/ssh/sshd_config file.

sudo systemctl restart sshd.service
