Hi List.
I have a issue concerning the usage of an ssh keypair. With that keypair it should only be possible to:
1.) scp, if possible restrict it to a specifiy directory 2.) ssh -R ...
Any ideas how to do that?
thanks / greets
Michael
Hi Michael,
What about making a separate user for that purpose and put him in a "rootjail" or restricted shell?
Cheers Eduard

See man 8 sshd. I thing that the best choice would be the parameter no-pty in authorized_keys file. It will disallow to set up the terminal session.

Too easy but that did the job.
Thanks.

I think it really is _too_ easy. if you don't have a tty, you won't get the bash prompt. but that is about all there is to it.
you still can do what ever bash can do. sorry.
you have to be much more restrictive in the authorized_keys file, possibly forcing certain commands. which could parse $SSH_ORIGINAL_COMMAND for additional info ...
