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.
$(el) yum install kbd $(deb) apt-get install $(arch) pacman -Sy kdb '-c,--current' lock only this virtual console, allowing user to switch to other virtual consoles '-a,--all' lock all virtual consoles by preventing other users from switching virtual consoles '-n,--new' switch to a new virtual console before locking all console sessions, needs to be compiled with plugin # lock current console $ vlock # lock all consoles (including virtual console); must run from virtual console $ vlock -a # lock whole system, switches to a virtual console and then locks as 'vlock -a' $ sudo vlock -n
physlock@github lightweight alternative to vlock, 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.
$ git clone https://github.com/muennich/physlock $ cd physlock ; make ; sudo make install '-d' fork and detach, useful for suspend/hibernate scripts '-l' only lock console switching '-L' only enable console switching '-u USER' allow the given user to unlock the computer $ /usr/local/bin/physlock
