Remote Desktop

[dale456654]

Hi,
I love Ubuntu but there is just one thing that I cannot get working. I have vista on this computer (Which I am going to delete after I get this working) when this computer is booted into vista then I type "192.168.1.65" (which is this computers internal ip address) and it connects to it without a problem. When I try this on ubuntu with KRFB running I type "192.168.1.65:5900" as it tells me to do with the added port number. This computer (This is the one I am Connecting to says "The remote user has been authenticated and is now connected." and when I hover over the icon it says "Desktop sharing - Connected with 192.168.1.70" which is my laptops IP address. On my laptop however it says "Remote Desktop Disconnected Because of a protocol error detected at the client (code 0x1104), this session will be disconnected. Please try connecting to the remote computer again." No matter how many times I try it doesn't work. Does anyone have any suggestions? I'm sorry for the lengthy post but I just really want to get this working!

Thanks for any help!

I managed to get it semi working...

I tried connecting from the computer in the living room which is running linux and it gave me 2 options, rdp and vnc. First i tried rdp as this is what remote desktop connection uses but it didnt work. I tried vnc and it worked... meaning that it uses vnc. I downlkoaded realvnc for my laptop and it works as it does in the living room, i just see a static picture of my desktop. when i move the mouse it moves on the computer but not on the computer im controlling it from.

Does anyone know how to fix this?

Thanks

I disabled compiz and replaced it with metacity and now things are happening on the screen but all the size and colours are messed up!?

Port 5900 gives away that it's using VNC. VNC is a remote desktop protocol with a few incarnations that are in theory compatible with eachother but in practice, well, you see the results. RDP is the Windows built-in remote desktop protocol. The Linux client for that is "rdesktop".

On the computer you're controlling from, the mouse usually shows as just a small dot, while the actual pointer is supposed to catch up and display with a small net lag delay. If you're not seeing the pointer at all on the local computer, your protocol may not be updating the screen, or there could be a video acceleration layer issue with the host that the realVNCserver isn't picking up on (do video's play or do they just show up as blank boxes?).

You can try to use a different VNC server on the host, or a different VNC client on your local computer (I think there's three unique available to Ubuntu: directvnc and xtightvncviewer for RFB version up to 3.8. Other packages are frontends to one of these or use the libgtk-vnc library (gtkvncviewer, gvncviewer, vinagre). There is also the tightvnc-java package with is platform independent.

Check what version RFB protocol the server is using... you might need to be using the xvnc4viewer client, which AFAIK is the only Linux client that supports the VNC RFB protocol exceeding 3.8.

AFA odd colors, check your bandwidth and compression options. You may be dropping to 8-bit color or using a compression method that's scrambling the color pallet. Hard telling not being there. All I can suggest here is to just play with your options and see if you can get an improvement.

I got it working!

I installed Vino with "sudo apt-get install vino" then went to system > preferences > remote desktop and checked what i needed.

Now I only wish I could get it multiuser...

NX Server (FreeNX) uses a remote login protocol, so while it's not really desktop sharing, it is good for a remote login desktop, thus multiple users. Also shares the sound server (useful on a local or broadband connection).

FreeNX Server is often what's used in Linux based thin client computing.
