Virtual console is a very important function on Linux. They provide system users with a shell prompt to ensure that they can still use it when logging in and remotely logging in to a system without a graphical interface.

A user can operate multiple virtual console sessions at the same time by switching back and forth between virtual consoles. The purpose of this guide is to teach you how to use vlock to lock users' virtual consoles and terminals.

What is vlock?

Vlock is a tool for locking one or more virtual console user sessions. Vlock plays an important role in multi-user systems. It allows users to lock their own sessions without affecting other users to operate the same system through other virtual consoles. If necessary, you can also lock all consoles and disable switching between virtual consoles.

The main function of vlock is for console session, and it also supports locking of non-console session, but the testing of this function is not complete.

Install vlock on Linux

Choose vlock installation instructions according to your Linux system:

# yum install vlock [On RHEL / CentOS / Fedora] $sudo apt-get install vlock [On Ubuntu / Debian / Mint] uses vlock on Linux

General syntax for vlock operation options:

# vlock option# vlock option plugin# vlock option-t pluginvlock common options and usage:

1. Lock the current virtual console or terminal session of the user, as follows:

# vlock-current

Good command to lock Linux user virtual console-volck good command to lock Linux user virtual console-volck

Lock the Linux user terminal session

The option-c or-current, which locks the current session, is the default behavior when running vlock.

2. Lock all your virtual console sessions and disable switching between virtual consoles, with the following command:

# vlock-all

Lock all Linux terminal sessions

Option-an or-all to lock console sessions for all users and disable switching between virtual consoles.

The other options work only if the relevant plug-in support and references are included when compiling vlock:

3. Option-n or-new, when called, switches to a new virtual console before locking the user's console session.

# vlock-new

4. The option-s or-disable-sysrq, which disables the SysRq feature while disabling the virtual console, works only when used with-an or-all.

# vlock-sa

5. Option-t or-timeout to set the timeout value of the screen saver plug-in.

# vlock-timeout 5

You can use-h or-help and-v or-version to view help messages and version information, respectively.

This is the end of our introduction, a hint, you can include the vlock ~ /. Vlockrc file in the system startup, and refer to the getting started manual to add environment variables, especially for Debian users.
