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].

Note: Although the AFS-16 does not support SSH1, the /K 1 command will still return a key for SSH1.
