Lightweight linux console locking tool.
Control physical access to a linux computer by locking all of its virtual terminals / consoles. physlock is an alternative to vlock, it is equivalent to `vlock -an'. It is written because vlock blocks some linux kernel mechanisms like hibernate and suspend and can therefore only be used with some limitations. physlock is designed to be more lightweight, it does not have a plugin interface and it is not started using a shell script wrapper.
