how to not update ssh keys and instead update a config
Long story short, keylometer provides an AuthorizedKeysCommand for sshd,
allowing us to not have to update our ssh keys ever. Just add a user to
the config ,and they can use our server.
The keylometer.yml file is an example of the config file. It is tried first
from /etc/keylometer.yml, and then in the current folder.
To make it work, build the program using go build, then copy it to a folder
that everyone can access. Then add the following to /etc/ssh/sshd_config:
AuthorizedKeysCommand /path/to/keylometer %u
AuthorizedKeysCommandUser nobody
The %u is important so Keylometer can figure out what keys to use for the
current user.
