The SSH client uses the list of known SSH servers to store the corresponding key. This file is changed each time a connection is established to an SSH server for the first time and the administrator accepts the key displayed for the remote system.
Each key is stored to a line in this file and contains three fields:
- The name or IP address of the remote system as entered into the SSH command when establishing the connection.
- The key type, i.e. ssh-rsa or ssh-dss.
- The binary output of the key itself, coded as Base64.
Note: Once an administrator has accepted the public key of an SSH server, this
key applies to all LCOS administrators; there is no differentiation
at user level.
