10. Telnet & SSH Functions
10.1. SSH Encryption
In addition to standard Telnet protocol, the AFS-16 also supports SSH connections,
which provide secure, encrypted access via network. In order to communicate with the
AFS-16 using SSH protocol, your network node must include an appropriate SSH client.
Note that when the /K (Send SSH Key) command is invoked, the AFS-16 can also
provide you with a public SSH key, which can be used to streamline connection to the
AFS-16 when using SSH protocol.
Although you can establish an SSH connection to the unit without the public key, the
public key provides validation for the AFS-16, and once this key is supplied to the SSH
client, the client will no longer display a warning indicating that the AFS-16 is not a
recognized user when the client attempts to establish a connection.
The /K command uses the following format:
/K <k> [Enter]
Where k is an argument that determines which type of public key will be displayed, and
the k argument offers the following options:
1. SSH1
2. SSH2 RSA
3. SSH2 DSA
For example, to obtain the public SSH key for an SSH2 RSA client, type
/K 2 and then press [Enter].
