HP-UX Secure Shell and chroot Environments
HP-UX Secure Shell versions A.04.50.009, A.04.50.010, and A.04.50.011 support chroot
functionality for the ssh, sftp, and scp commands. The chroot functionality is
mainly used as an added security measure.
When you enable chroot, you can start an application in a specified directory and
enable all its users access to that directory and the directories below it. It prevents users
from using the cd command to access directories at a higher level. Use this functionality
to enable restricted file and directory access to users of a particular application. This
is not an end-user feature. The system administrator must enable the chroot
functionality for an application. All users of that application will automatically be
subject to the restrictions imposed by chroot.
See the README file at /opt/ssh/README.hp for more information on setting up the
chrootfunctionality. Thechrootsetup script is available at
/opt/ssh/ssh_chroot_setup.sh.
