10. SSH Encryption
In addition to standard Telnet protocol, the MPC also supports SSH connections, which
provide secure, encrypted access via network. In order to communicate with the MPC
using SSH protocol, your network node must include an appropriate SSH client.
Note that when the /K (Send SSH Key) command is invoked, the MPC can also provide
you with a public SSH key, which can be used to streamline connection to the MPC
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 MPC, and once this key is supplied to the
SSH client, the client will no longer display a warning indicating that the MPC 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 MPC does not support SSH1, the /K 1 command will still
return a key for SSH1.
