vtdaemon(8)

Name

vtdaemon - switch function between text virtual consoles

Synopsis

/usr/lib/vtdaemon

Description

vtdaemon provides a secure switch function, by means of hotkeys, between different text virtual consoles. It runs with full privileges. See vt(4I) for specifications of hotkey sequences.

The service is managed using the action authorization solaris.smf.manage.vt which is included in the Device Security Rights Profile. The service is local only and has no inbound network ports. It is disabled in non-global zones or when the virtual console functionality is not available.

vtdaemon uses PAM for authentication.

Note that vtdaemon only locks and unlocks the text console. For graphical X sessions, it invokes the corresponding lock program (for example, xscreensaver), which deals with authentication and audit.

Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(8). The service's status can be queried using the svcs(1) command.
