Hi all.
We're in the process of establishing an open remote desktop service for the
users of our HPC-cluster. The plan is to provide an unrestricted vnc access
to the login screen (using xdm) and require TLSnone as encryption for all
connections. So, my question to the forum is: Do anyone have experience in
running such a service in a production environment? Are there any pitfalls we
should be aware of?
Yes, I'm aware that we will be exposing the xdm login screen to the whole
world, but we're currently allowing this for ssh login so in principle we're
already having our jewels hanging out there...
If we can pull this off we will be able to improve our service level by
offering
a simple linux desktop (XFCE) to our users without requiring anything from
their side than a java-enabled web browser.
In the test setup we have 16 login servers behind a NAT firewall and a simple
web frontend that hands out the vncviewer jar and picks a random server among
the 16. I can even run sophisticated 3D molecular modelling software from my
dirt cheap android tablet (using the bVNC app).
I must say that I'm really impressed with the quality of the TigerVNC
software.
So, any hints or comments is greatly appreciated.
Regards,
Roy.
