NAME
sux - wrapper around su which will transfer your X credentials
SYNOPSIS
sux [OPTS] [-] [[username] [ARGS]]
suxterm [OPTS] [-] [username]
DESCRIPTION
sux is a wrapper around the standard su command which will transfer
your X credentials to the target user.
Note, suxterm forces ARGS to be ’xterm’, and will try to launch an
xterminal window.
QUICK CALLING
’sux user’ and ’sux - user’ behave just like su but transfer $DISPLAY
and the X cookies.
OPTIONS
--untrusted
To generate an untrusted cookie, see ’xauth’.
--timout <period>
To generate a temporary cookie for <period> seconds, see
’xauth’.
-m,-p --preserve-environment
In this case sux will override XAUTHORITY to the so that xauth
does not try to use the original user’s .Xauthority file (which
it obviously could not do anyway due to access rights).
--no-cookies
Just transfer DISPLAY, not the cookies. You could do this if you
have already transfered the cookies in a previous invocation of
sux.
--copy-cookies
Copy the cookies using xauth. This is the default method (and
only method most of the time).
--use-xauthority
Instead of transfering the cookies, set the XAUTHORITY
environment variable to access the original .Xauthority file.
There’s a couple caveats with this method. First, due to the
access right issues it’s only usable by root. But even then it
may not work if the .Xauthority file is accessed via NFS, e.g.
if the home directories are on NFS (note that this is quite
dangerous already since your cookies will travel unencrypted
over the network). Then, if root runs commands like xauth
add/remove, the .Xauthority’s ownership will belong to him. This
will leave the original user in trouble as he will no longer be
able to access X! So only use this option with great care.
Finally, this method does not work if you also want to use
’--untrusted’ or ’--timeout’.
--display
specify which display to use (in case of having more than one
available).
