Title: Generating new SSH host keys for Yún security
Post by: ethanhall9 on Apr 21, 2019, 07:14 pm
Does this (see below) mean that the Yún does not generate ssh keys during setup?

The host keys have a date stamp of April 27, 2018 in the file system, even though I recently bought it and set it up. Which means all Yún owners probably have the same keys?.....

If so, isn't that insecure, and how do I generate new and secure host keys with dropbear suited for the Yún?
