comment dhcp ipv6 dynamic prefix delegation
Having said that, and notwithstanding the fact that it is technically possible to subnet in v6 to longer prefix lengths than /64, DHCPv6 PD is not actually going to work properly in this case because the ISP is handing out a /64. There is only one subnet, thus nothing to split up and delegate. The ISP should not be handing out a /64, they should be handing out a /48 per customer or at the very least a /56 per customer.

comment dhcp ipv6 dynamic prefix delegation
I don't agree that this is too broad. It's about configuring DHCPv6 PD, which is theoretically simple to do but it's still kind of a new thing so best current practices have not really emerged so I think there's a lack of usable recipes, which makes this actually quite a good question.

comment How to grant user teminal access in VNC
If you're concerned about system resources consumed by many concurrent VNC sessions, start a really lightweight environment such as the bare-bones twm window manager and xterm as you demonstrate in your screenshot. Or better yet, let people log in with SSH instead of VNC. That will be much, much, ligher, and more convenient for the users to boot.

comment How to grant user teminal access in VNC
If yes, this is really a security question and has nothing to do with VNC. In that case the answer might be something like mumble mumble restricted shell, but honestly it's not going to work that well in the sense that they're not really going to end up with a "real" shell. If no, then I must confess that I don't understand what your utimate goal is.

comment How to grant user teminal access in VNC
Let me try to clear up misconceptions (or something). You can choose what starts up when the VNC session is initiated. It could be anything from a full GNOME session with desktop and file browser, to a very simple window manager with 1 or 2 applications only, or even a big xterm filling the screen and nothing else. But basically, once you give them a shell, they can run whatever additional software they want which is installed on the system (or even install their own), that's part of what having shell access means. Are you trying to prevent / lock down what software they can run?
