That should keep them from logging in at all. Which is very secure. :)
The problem is that in order to run the browser I think you have to have
a shell running. I suspect if you put the browser in place of the shell
in the passwd file it would not work. (might be worth a quick test
I really think the best option is to try and setup chrooted access. If
they manage to get a shell prompt they are restricted in what they can
If I chroot the restricted user, what are the minimum commands that
should be available in order for him to be able to run firefox ? is a
shell required ?
