consolehelper - A wrapper that helps console users run system programs
progname [ options ]
consolehelper is a tool that makes it easy for console users to run
system programs, doing authentication via PAM (which can be set up to
trust all console users or to ask for a password at the system adminis-
trator’s discretion). When possible, the authentication is done graph-
ically; otherwise, it is done within the text console from which con-
solehelper was started.
It is intended to be completely transparent. This means that the user
will never run the consolehelper program directly. Instead, programs
like /sbin/shutdown are paired with a link from /usr/bin/shutdown to
/usr/bin/consolehelper. Then when non-root users (specifically, users
without /sbin in their path, or /sbin after /usr/bin) call the "shut-
down" program, consolehelper will be invoked to authenticate the action
and then invoke /sbin/shutdown. (consolehelper itself has no priv-
iledges; it calls the userhelper(8) program do the real work.)
consolehelper requires that a PAM configuration for every managed pro-
gram exist. So to make /sbin/foo or /usr/sbin/foo managed, you need to
create a link from /usr/bin/foo to /usr/bin/consolehelper and create
the file /etc/pam.d/foo, normally using the pam_console(8) PAM module.
This program has no command line options of its own; it passes all com-
mand line options on to the program it is calling.
