vlock is a program to lock one or more sessions on the Linux console. This is especially useful for Linux machines which have multiple users with access to the console. One user may lock his or her session(s) while still allowing other users to use the system on other virtual consoles. If desired, the entire console may be locked and virtual console switching disabled. License: GNU General Public License v2 Changes:
Vlock's architecture was again changed from using multiple executables to a single one with plugin support. The main helpers "vlock-all", "vlock-new", and "vlock-nosysrq" were all converted to plugins to keep filesystem based permission checking. Plugins may be scripts or shared objects and can add functions like muting the sound, pausing music or movie playback, and even eye candy screen savers.
