I am trying out a EC2 desktop instance with the aim of using it to provide virtualised training. Using the nxclient from NoMachine and the installed neatx on 10.10 I have been able to get good desktop performance, even on a heavily loaded office link.
However the ability to connect to the instance is quite problematic. Often the nxclient (running on Mac) times out. The debug logs show that authentication succeeds, the server responds with nx> 105. At this point nx client should request a list of open sessions, but instead just goes silent, eventually timing out.
Most frustrating is that it *sometimes* works, that's how I know what it should be doing (by looking at the successful connections in the debug log).
Can anyone here recommend a website, debugging tools or other forums? How about a known working combination (e.g. FreeNX). Using the Nomachine server isn't really an options, since I'll need 10+ people connecting during training, although if that's the only way, I'll have to go back and suggest we spend the money to buy it.
I'm not stuck using 10.10, so if Lucid is a better choice, happy to downgrade, although my experiments this morning show the same problem with Lucid.
