HP-UX Secure Shell and chroot Environments
HP-UX Secure Shell versions A.04.70.021, A.04.70.022, and A.04.70.023 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.
