Lock Linux Server
Secure your servers against unauthorized physical access.
Lock your Linux Servers using “vlock” tool.
RHEL admins can install it using –
yum install vlock
(yes it comes with standard RHEL iso)
Ubuntu admins can install it using –
sudo apt-get install vlock
Once installed you can activate it by just entering “vlock” on your Virtual consoles (expecting that you are running your Linux Servers in runlevel 3)
Here is a small illustration from my machine.
