Is there a way to do this without installing a package like rssh or scponly, as they seem woefully out of date and full of security problems? Is there any newer tool I could use? ssh is an optional requirement, just being able to scp would be good also.

Can't use sftp, or else openssh configuration would do.

    You can start a sshd daemon in a "chroot jail", as long as you don't use an already used port (TCP/22 as default). You need the binary, all related libraries and some additional parametters to start the daemon on a different port. Dec 6, 2019 at 12:32

  • @poige That sounds interesting, so I could use the pam module instead of using jailkit at all? And if not, at least jailkit is being updated still!
