The version of TurboVNC in the yum repository from Open Ondemand (https://yum.osc.edu/ondemand/1.6/compute/el7Server/x86_64/) is a bit outdated.
It now hosts version 2.1.1 which contains a nasty bug where it fails to start VNC. We hit it at our site.
Ric I’d guess ondemand-compute-1.6-1.el7.noarch.rpm pulls that in.
Looks like we pushed 2.1.9 to that repo but looking at the ticket, but the reporter says that version’s affected too? If you want updates like this, github is a better reminder for us so I’ve created this issue for that.
Thanks for the heads up, I think we should upgrade. I assume you upgraded manually to resolve your issue?
