PKTTYAGENT(1) pkttyagent PKTTYAGENT(1)
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.
