I try to create some safe shell for some users and I use chroot.I havd
created the directory /bin,/lib/,/tmp and copied the files
"bash","chroot" to the /bin.
I add the following line to the file ".bash_profile":

chroot /home/safeshell /home/safeshell/bin/bash

It can't work. The error message is "chroot:can't change the root
directory to
/home/safeshell:Permission Denied

Why???My os is Turbo Linux 6.1
Thanks!!!

It looks as though you are trying to execute chroot as a non-root
user. Only root can chroot.

Furthermore, the path to the shell should be /bin/bash, not
/home/safeshell/bin/bash, since the chroot command will attempt to
execute the shell after /home/safeshell has become /, not before.
