restricted access to directory

[Daniel Ubeda]

Hi,

How can I do to restrict the access to a directory from a user ?
I need to assign to user X this home: /home/u1/X, and I need that this user can move up one level (/home/u1) and navigate, copy files, move files, etc.
I can use rsh, but I need to move up one level, and rsh not permit that.
any idea ??
thanks

Give him rsh as his shell and then create symbolic links from in his home directory to the directories that you wish him to access.

Unless I'm missing something, I think you would need to use group permissions. If user x belongs to group y and /home/u1 is owned by group y, that should accomplish what you seek.

I have test the symbolic links solution, and rsh (and rksh) shells, but it not work because the rsh and rksh limit the use of cd command.

any idea ??

The symbolic links will work; you, of cource can't cd to them under rsh.

e.g.

In your users home dir:
ln -s /home/user1 myuser1

Now you can copy any files from myuser1. ls myuser1 will list the files and ls -Ll myuser1 will do a long listing. You can do all the operations you require; you just have to do them a bit differently.

Also experiment with the SETGID bit which makes a file executable to the group. Use:

chmod 2### /dir
-or-
chmod g+s /dir

Examples: With execute permission.

-rwsr-sr-- 1 bill user 242 Jun 13 2002 abc1

Without execute permission.

-rwSr-Sr-- 1 bill user 242 Jun 13 2002 abc2
