Don't do it.

*never* permit root-level access directly to *any* of your equipment.

You want to provide as many levels of escalation to root level as you
can, no matter what protocol you are using.

Auth in as a normal user (as you stated is already working), and then
use sudo(8) to escalate yourself.

If you can already "ssh [host]" as a normal user, then you already have
the concept of keys.

You can automate the escalation after you've authenticated, and then do
what you want to do.


...don't do it.



# pkg_add -r sudo
# rehash
# man sudo

Then, when/if you have problems with specific functions that need root
privileges, ask those questions here instead.
