PROGRAM:

NAME


pkttyagent - Textual authentication helper

SYNOPSIS


pkttyagent [--version] [--help]

pkttyagent [--process { pid | pid,pid-start-time } | --system-bus-name busname]
[--notify-fd fd] [--fallback]

DESCRIPTION


pkttyagent is used to start a textual authentication agent for the subject specified by
either --process or --system-bus-name. If neither of these options are given, the parent
process is used.

To get notified when the authentication agent has been registered either listen to the
Changed D-Bus signal or use --notify-fd to pass the number of a file descriptor that has
been passed to the program. This file descriptor will then be closed when the
authentication agent has been successfully registered.

If --fallback is used, the textual authentication agent will not replace an existing
authentication agent.

RETURN VALUE


If the authentication agent could not be registered, pkttyagent exits with an exit code of
127. Diagnostic messages are printed on standard error.

If one or more of the options passed are malformed, pkttyagent exits with an exit code of
126. If stdin is a tty, then this manual page is also shown.

If the authentication agent was successfully registered, pkttyagent will keep running,
interacting with the user as needed. When its services are no longer needed, the process
can be killed.

NOTES


Since process identifiers can be recycled, the caller should always use pid,pid-start-time
when using the --process option. The value of pid-start-time can be determined by
consulting e.g. the proc(5) file system depending on the operating system. If only pid is
passed to the --process option, then pkttyagent will look up the start time itself but
note that this may be racy.
