What is authprogs
authprogs is:
authrpogs is invoked on an ssh server and decides if the command
requested by the ssh client should be run or rejected based on
logic in theauthprogsconfiguration file.
Passwordless SSH using ssh identies or pubkeys can enable all
sorts of wonderful automation, for example running unattended
batch jobs, slurping down backups, or pushing out code.
Unfortunately a key, once trusted, is allowed by default to run
anything on that system, not just the small set of commands you
actually need. If the key is compromised, you are at risk of a
security breach.
Authprogs is enabled by using the command= option in the
authorized_keys file.
