Pete-
Using xhost is the X preferred way of loosening X security restrictions.
As xhost is an X client app, you could run it either client-side or
server-side - in other words, you could make it a server-side script
that runs upon login, as well (unless you need access to the Xserver
prior to login).
You should also note that ldm has a directory structure for adding
custom scripts, so you needn't hack up the scripts provided by the
package. There is:
/opt/ltsp/i386/usr/share/ldm/rc.d/
If you drop a script in this directory, with the appropriate prefix, it
will run at the appropriate point within the ldm sequence. Prefixes
are:
I - "init", which is executed after Xserver starts bu before greeter
appears.
S - "Start", which is executed after successful login.
K - "Kill", which is executed after successful logout.
X - "X", which modifies the connection made to launch the desktop via
ssh.
The structure is similar to the rc.d structure of SysV, and all scripts
are sourced. You can order the scripts with the appropriate ordering
numbers.
Check out that directory for details.
This way, you can add your own hacks as separate files that will not be
impacted upon upgrade.
Also, note we have similar structures for general X screen scripts:
/usr/share/ltsp/xinitrc.d/
and general session scripts (pre-launching Xserver):
/usr/share/ltsp/screen-session.d/
All have similar structures, though screen-session.d scripts have an
additional prefix "XS" which is used to setup xorg.conf.
Happy hacking!
