This already works if you don't use the -s switch to vglconnect. Why
it's failing with -s is that -s causes vglconnect to run vgllogin on the
server, so any additional arguments are interpreted as SSH options
instead of as a remote command. I added a new vglconnect option, per
your suggestion, that allows you to specify a program to run on the server:
e.g.
vglconnect -s -C -e 'vglrun /opt/VirtualGL/bin/glxspheres64' myserver
New script is attached. Let me know if it works, and if so, I'll check
it in.

I don't think it would be very difficult to add that functionality, given that
vglconnect is basically just a wrapper for SSH. Let me look at it further and
get back to you.

Hi,
we're currently successfully using vgl to start our applications like:
myclient$ vglconnect -s -C myserver
myserver$ vglrun glprog
We cannot sell our users a program which requires using the
command-line, so we need to create a startup button. Thus we need a
non-interactive startup of 'vglrun glprog', e.g. (not working!)
myclient$ vglconnect -s -C myserver vglrun glprog
Does there exist a vgl-program/option which allows starting
vglconnect/vglrun from the client-machine?
If not, is there some interest to add that functionality, e.g.
myclient$ vglconnect -s -C -E 'glprog' myserver
(I checked the vglconnect/vgllogins skript and it doesn't seem to hard
to add these parameters, so I could volunteer.)
Best regards,
Heiko
