SSH Configuration

====================================================================================

What is SSH?

-----------------------------------------------------------------------------------------------------------------------------------------------

SSH Configuration

When it comes to SSH configuration, we're either talking about the SSH client, or the SSH server. (Ttypically both are installed on Linux Systems)

The configuration for the SSH server is located in /etc/ssh/sshd_config

The configuration for the SSH client is located in /etc/ssh/ssh_config

SSH Server Configuration Options

NOTE: Any changes made to the sshd_config won't be applied to your session until you reconnect (and restart SSHD).

These are all options that can be added to the SSH server (sshd_config) configuration file.

Port 22 Specify port for SSH server to listen on.
Listen Address IP_IP_IP_IP Change the IP that the SSH server listens on
PasswordAuthentication yes Enable password authentication

Known Hosts

known_hosts is a file kept in the home directory of a user. This file contains the fingerprint key of each SSH-server that a connection has been made to. This is a security feature within SSH as it allows for host fingerprint keys (unique) to be validated before the connection is established.

~/.ssh/known_hosts
