Mass control... More Control... Better Control
Mass control... More Control... Better Control
For Example if I want all the servers to all do one thing at one time by following one viewer or transfer files to several servers at once. Also remote shutdown without viewing, and making an UI to group the servers so you can do batch jobs by clicking on one group... like remote shutdown all the computers in group one, or remote file transfer to all the computers in group 2. Have you guys seen the new Remote Administrator (http://www.famatech.com)... sorta like that[/url]
Re: Mass control... More Control... Better Control
Nope, I haven't seen the "new" one, I waited a year or two for that and finally gave up. That's why I'm here instead loldngunraj wrote:Have you guys seen the new Remote Administrator (http://www.famatech.com)... sorta like that[/url]
Eventually they will probably get to Radmin-like features. I'd say that's the ultimate goal. We're just pushing for v1.0 right now tho. I suggested a tabbed interface for the Viewer recently. I admit I'd like a phonebook-type interface like Radmin's too. But for now you can always use a third party util or just save the .vnc files in a folder for the phonebook thing. Mass control would be awesome but I suppose it's a bit far off - except maybe for the tabbed idea. I hope one of the devs out there liked that idea
3rd party utils:

I think one of those allow for multiple viewers. Not sure, though...

Multicast for classroom teaching is a great idea; only problem is that multicast is a type of UDP => not guaranteed delivery.
So some kind of retransmission scheme must be implemented, similar to NAT traversal with UDP packets, but with new interesting challenges:
- how to handle latecomers (new clients during an ongoing session)
- how to pace updates without requiring acks from each and every client
- how to detect/signal retransmit requests
- which client (if any) owns the keyboard/mouse
There is already an old multicast VNC available (google for vnc teleteaching) but I haven't looked at how they decided to do it.
