OpenSSH scp restrictions a-la gitolite

Question

Does anyone know of some software that would allow to restrict/tune the scp experience on a single unix user, based on SSH keys?

Similar to what gitolite does, or more flexible what rssh can do, but without chroot level tricks, so that any restrictions/limitations would be implemented solely by the alternative SCP subsystem implementation?

Answer 1

meaning you only want the user with a certain pubkey to only be able to perform certain commands or only SCP?

there is, if i recall, a command string for remote scp calls. this can also be done via rsync.

but regardless, you can specify only certain commands for certain pubkey pairs via the link above.
