Embedded Devices and Internet of Things Available entropy can be a real problem on small that don't have much other activity on the system. The program generates the keys for you. However, in large organization and when the keys change, maintaining known hosts files can become very time-consuming. See the documentation for on how to set it up. Authorized keys and identity keys are jointly called user keys.

If you supplied a passphrase for the private key when you created it, you will be prompted to enter the passphrase now. This document contains more information on specific versions and software images. There have been incidents when thousands of devices on the Internet have shared the same host key when they were improperly configured to generate the key without proper randomness. We recommend using for all identity keys used for interactive access. Each line contains one key, which consists of the following fields: options, bits, exponent, modulus and comment. Thus, they must be managed somewhat analogously to user names and passwords.

If the first command doesn't show anything useful then I'd say you can go ahead and generate a new key. They also allow using strict host key checking, which means that the clients will outright refuse a connection if the host key has changed. Furthermore, embedded devices often run on low-end processors that may not have a hardware random number generator. You can send me a message on LinkedIn or email to arranda. Our recommendation is that such devices should have a hardware random number generator.
