I've been trying to go through all the known_hosts files manually and
update them to give my users a break, but it's a tedious nightmare.
Adding to the complexity is that many of the known_hosts files are
armored (the hostname/ip address is not in plain text).
Has anyone come up with a way to read all the cached hosts - all the

Essentially I need some semi-automated way to fix this since I have many
users's connections to fix still (hundreds if not thousands by the time I
do machines X users X outgoing connections).
