restrict access of a user to two directories only - Page 2 - Linux

vikas027 · #8 (**permalink**) 04-15-2008

Hi all,
Now i got some success in achieving jail.

I have used the above mentioned script fuschlberger.net - Howto Setup a chroot-jail for ssh/scp with Linux and ran it as

Code:

Quote:

./make_chroot_jail.sh jdoe /bin/bash /home/jail/./home/jdoe

Now, I need to give full access to other two directories to jdoe, say /tmp1 and /tmp2 which at present I cannot access when I login as ssh jdoe@localhost.

Here, I am pasting my variables.

Code:

bash-3.1$ set
BASH=/bin/sh
BASH_ARGC=()
BASH_ARGV=()
BASH_LINENO=()
BASH_SOURCE=()
BASH_VERSINFO=([0]="3" [1]="1" [2]="17" [3]="1" [4]="release" [5]="i686-redhat-linux-gnu")
BASH_VERSION='3.1.17(1)-release'
COLUMNS=157
DIRSTACK=()
EUID=501
GROUPS=()
HISTFILE=/home/jdoe/home/jdoe/.bash_history
HISTFILESIZE=500
HISTSIZE=500

IFS=$' \t\n'
LD_LIBRARY_PATH=/usr/kerberos/lib

PWD=/home/jdoe/home/jdoe
SHELL=/bin/bash
SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitor
SHLVL=1
SSH_CLIENT='127.0.0.1 43358 22'
SSH_CONNECTION='127.0.0.1 43358 127.0.0.1 22'
SSH_TTY=/dev/pts/0
TERM=xterm
UID=501
USER=jdoe
_=set
-bash-3.1$

How, can I modify the script (or some other way) to achieve this ????

Pls help.

Thanks.

Like Jim suggested, add hard links to those directories to the root of the user's chroot jail.

Or do it the other way round, move them into the chroot jail and give other users access to those directories as necessary.
