I set up a kiosk session that presents a chooser (based on a setup from
Craig Benders Think Thin Blog) with a list of back-end servers that are
connected via RDP (uttsc) or XDMCP (Xephyr). Other protocols like VNC, NX
or whatever should work as long as the client is available for Solaris.
This setup would allow us to run desktop sessions despite the fact that the
backend server OS (the linux flavour of the day?) might not be supported by
SRSS. Even some sort of load balancing should be possible to implement
without to much effort (check load of backend server pool members before
actually connecting to one of them).
My current problem seems to be audio with a linux back-end server, as I
don't have an idea how to forward the audio from the back-end server to the
nested X session.
If you're using SRS 5.4 then it should have the new PulseAudio-based
audio subsystem. (On Solaris the old SADA subsystem is still
available for backwards compatibility. Each session should have a
'utaudio -p' daemon for Pulse and a plain 'utaudio' for SADA.)
Pulse is supposed to be able to deliver audio across the network, so
if the audio apps on your back-end Linux systems are built on the
PulseAudio libraries then you might be able to have them deliver
their audio streams to the SRS machine.
This should work even if the audio apps does not have have built in
PulseAudio support. For example, with OSS applications, you can use the
"padsp" wrapper. With ALSA applications, it is possible to use the
ALSA-PulseAudio-plugin, which we contributed to the ALSA project back in
2006. It's available on most modern Linux distributions. (See also
