close ssh users to the home directory

Hello,

I must close ssh users to the home directory.
It means the users musn't see anything inside their home directory.

For example after login to the os and type this command "cd .."
or "cd /" it musn't work.

How can I implement it?
(Probably chroot or rootsh but how?)

Have a look here
I never tested procedures in full but I believe it may give you some hints
