Mohammad,

Do you have a copy of the shell (sh) in /var/www/html/bin ? If not, just make 
one. Since your script needs to be executed with /bin/sh and your new root is 
/var/www/html you need a bin directory and a shell in this directory. The 
directory structure of your libraries in your new chroot environment has to 
be the same as in your "normal" system, but just underneath /var/www/html.

As I have not used CGI scripts with TUX I don't know if there is a bug in 
current TUX versions, but I am using TUX modules which are chroot'ed as well 
and everything works fine with them if I make a copy of essential directories 
from / to /var/www/html.

You can check whether your script works in a chroot environment by doing the 
following:

1. open an xterm (or another console)
2. create the directory /var/www/html/bin
3. copy /bin/sh, /bin/ls and /bin/cp into this directory
4. copy your script to some location underneath /var/www/html
5. issue the command: chroot /var/www/html
6. execute your script

And read the man pages about chroot ;-)

Bye, Marcus
