Hi Terminalguys :) I already posted this mail to the vnc mailinglist - but I think a posting here will give me more feedback about this. As far as I can see, the "roaming Desktop" feature in Thin Computing with Linux is still to be done. With X itself, we have no option - it would be VERY difficult to implement, because how should one tell the X-App that the User "moved" from Terminal A to Terminal B ? Perhaps some sort of "X-Proxy" would be an option - but I think, the most compromising approach for this, is to enhance VNC for that purpose. Please give me feedback, what you think. Since i`m sysadmin/sysengineer i`m not very good in programming, but if there is interest, I would at least try to start and maintain a project, which aims at giving "session management" (and loadbalancing???...) feature to VNC.
regards Roland ---------------- hello! i`m using a setup of xvnc under inetd and kdm control, so each user can connect and get`s his own desktop. noone has to "fiddle around" with dedicated port-numbers, which he has to connect to. this makes the "linux terminal server alterative" become somewhat realitiy, but unfortunaly, we loose the "preserve session state"-feature of vnc here, because each time the user closes vncviewer, the serving xvnc process dies. see very good docs at: http://www.sourcecodecorner.com/articles/vnc/linux.asp I wonder, if there is anybody around, thinking of implementing a layer of "session management" into vnc, that users can reconnect to (one of) his previously established and disconnected session(s). This would make the "roaming desktop" possible - without the need, to assign dedicated port numbers to users and pre-spawning xnvc processes for ALL of them. It could be done by adding a "dispatcher" in front (or inside?) xvnc which is able to manage sessions previously established. sure, some sort of authentication needs to be done at this level, because the only reasonable way to re-establish sessions and to route it to the appropriate client, is to get known, WHO is reconnecting. I administer citrix servers, which have this feature - when the user reconnects he is routed to his old session. if he has more than one disconnected session, he can choose, which he wants to re-establish. I also have some experience with sunray terminals - which have this feature in "2 flavours". The user is able to re-establish a disconnected session by entering login/password OR by using a smartcard (whereas the sunray x-server process[==xvnc] is "bound" to a smartcard - so the user inserts his smartcard at any terminal and gets back his personal desktop) are there any solutions around or is there any work in progress, implementing this with vnc ? i`m really shure this IS possible with reasonable effort. (unfortunately i`m awful bad programmer, otherwise i would do that myself :) regards roland ------------------------------------------------------- This SF.net email is sponsored by:Crypto Challenge is now open!
