NX does not just compress graphics. NX uses the encryption of SSH. >From what I have read and tried I can comment the following. I have tried NX server with Knoppix at one location and the client at a friends house. With 1.5Mbs ADSL it was *MUCH* better than VNC. I even could play Kasteroids as if it was local. This is fantastic technology. It works by compressing the X protocol and using SSH to deliver it. So it's compressed and encrypted by SSH. I'm pretty sure VNC is only secure for the password after that nothing is encrypted (or compressed). The advantage of VNC is that it requires almost no cpu strength. Whereas NX requires both server AND client to compress/decompress. So the client needs some cpu/memory muscle. In terms of LTSP the client would need to run the NX client app locally. I have noticed a startup company that has just started to advertise on osnews and distrowatch that sells this setup. Using freeNX with LTSP has been discussed on the k12lstp list and the upshot is that it's not worth it for a 100Mbs LAN (especially switches with Gig-E uplinks) because there is a local app problem plus the clients need to be fatter. But I think it's great for low bandwidth/fat client situations. -- Robert Arkiletian C++ GUI tutorial http://fltk.org/links.php?V19 ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
