Description Kjetil T. Homme 2000-02-08 02:25:24 UTC

If DISPLAY is set to point at server which root lacks access to,
you can get two equally absurd results:

# /sbin/reboot
Xlib: connection to "haey.ifi.uio.no:0.0" refused by server
Xlib: Client is not authorized to connect to Server

Broadcast message from root (pts/0) Tue Feb  8 03:27:36 2000...

The system is going down for reboot NOW !!

(this "works")

# /sbin/reboot
X11 connection requests different authentication protocol:
'MIT-MAGIC-COOKIE-1' vs. ''.
Gdk-ERROR **: X connection to ifi.uio.no:11.1 broken (explicit kill or
server shutdown).
#
(this fails completely)

Lowlevel tools like reboot has no business talking X11.

(I couldn't reproduce this behaviour when I rebuilt sysvinit from the
SRPM.)

Comment 1 Bill Nottingham 2000-02-08 18:17:59 UTC

Is /usr/bin before /usr/sbin in your path
(and before /sbin); if so, you're running
into the pam_console stuff. Having /sbin
and /usr/sbin before /usr/bin in root's path
will fix this.

Comment 2 Riley H Williams 2000-02-09 18:45:59 UTC

My understanding is that to avoid problems like this, the correct path prefix
for root is...

    PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin

...but raw installs of RedHat 6.1 appear to vary here depending on precicely
which packages are installed. I haven't managed to isolate this to any
particular package though.
