The SSH Client Known Hosts are used by all applications that play the role of an SSH Client. Specifically Tunneling in Connect Mode.

At the very least, a Password or Key Pair must be configured for a user. The keys for public key authentication can be created elsewhere and uploaded to the device or automatically generated on the device.

If uploading existing Keys, take care to ensure the Private Key will not be compromised in transit. This implies the data is uploaded over some kind of secure private network.

WARNING: When generating new Keys, using a large Bit Size will result in a VERY LONG key generation time. Tests on this hardware have shown it can take upwards of:

2 minutes for a 512 bit RSA Key
5 minutes for a 768 bit RSA Key
15 minutes for a 1024 bit RSA key
10 minutes for a 512 bit DSA Key
30 minutes for a 768 bit DSA Key
70 minutes for a 1024 bit DSA key

The default Remote Command is 'shell' which tells the SSH Server to execute a remote shell upon connection. This command can be changed to anything the SSH Server on the remote host can execute.
