vlock for Debian
----------------

vlock is a denial of service tool.  Linux allows any user logged into the
virtual console to lock the system completely.  vlock takes this one step
further and potentially grants this ability (and potentially other, even more
hazardous ones) to any user through the use of plugins.

The debian packages sets permissions that allow only users in the vlock group to
run dangerous modules.  Others will still be able to lock their own console or
terminal and run plugins that are considered secure. But they are for example
not allowed to lock all consoles.

Scripts
-------

You can extend the functionality of vlock with scripts. Some example scripts
have been placed in /usr/share/doc/vlock/examples/scripts/. To use on of them
install it to /usr/lib/vlock/scripts and make it executable. Scripts will be
executed as the user executing vlock. For more information see
/usr/share/doc/vlock/PLUGINS.
