The ssh client in LCOS automatically stores the known SSH keys of remote systems to its own key file. This key file is stored in the internal file system and named ssh_known_hosts. The contents of this file change each time you connect to an SSH server that is unknown to your device and you accept the remote-system key displayed to you as a security prompt.
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.
Important: Once an administrator has accepted the public key of an SSH server, this key applies to all of the administrators; there is no differentiation at user level.
Important: The file(s) named here on the device are exclusively available to the root administrator via SCP (see Loading a file via an SCP client). Uploading and downloading via LANconfig or WEBconfig is not an option.
