Restrict usage of ssh-keypair

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 -- GiS - Gesellschaft fuer integrierte Systemplanung mbH +==================================================================+ Michael Scherer mscherer@gis-systemhaus.de Tel: 06201-503-74 Junkersstr.2 69469 Weinheim Fax: 06201-503-66 +==================================================================+ It's a book about a Spanish guy called Manual, you should read it. -- Dilbert
