[Mauiusers] maui.cfg on a shared directory??

Dear all,

I'm trying to setup Maui with the following configuration:
Maui server running on the same machine hosting the torque server
(configured --with-spooldir=/var/spool/maui - this is where the maui.cfg
file ends up being) and client commands (configured as default) on a nfs
share exported to the local network of machines. I have setup Maui to
talk to PBS over port 15005 which works fine, I think (at least it works
well on another 2-node setup I have)

Commands such as showq (from a client machine) want the maui.cfg to be
in /var/spool/maui (not sure why), so I got round this by creating on
the client machine a symbolic link /var/spool/maui/maui.cfg to the real
configuration file sitting on the shared directory. All of this seems in
principle right, but I must be doing it the wrong way as the clients do
not seem to be able to get proper communication with the server:

Any idea to help me out of this?? By the way, the error persists even if
I copy over to the client machine the maui.cfg file rather than symlink
it.

cheers,
gianfranco
