27.2.1 OpenSSH User Configuration Files

To use the OpenSSH tools, a user must have an account on both the client and server systems. The accounts do not need to be configured identically on each system.

User configuration files are located in the .ssh directory in a user's home directory (~/.ssh) on both the client and server. OpenSSH creates this directory and the known_hosts file when the user first uses an OpenSSH utility to connect to a remote system.
