Описание (Description)
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.
By default, only the current VC (virtual console) is locked.
With the -a,-all option all VCs are locked. The locked VCs
cannot be unlocked without the invoker's password. And, for the
paranoid, vlock makes it a trying experience for those attempting
to guess the password, so unauthorized access to session(s) is
highly unlikely.
Please note that it is entirely possible to completely lock
yourself out of the console with the -a,--all option if you
cannot remember your password! Unless you are able to kill vlock
by logging in remotely via a serial terminal or network, a hard
reset is the only method of ``unlocking'' the display.
vlock works for console sessions primarily. However, there is
support for trying to lock non-console sessions as well, but that
support has not been well tested.
