Working to set up the GnuPG keymanager for SSH and now FreeNX server on CentOS 6 and NoMachine NXclient on my new install of ArchLinux I've been reading more about keys than I've ever read before. I'm at the level of "A Postal Analogy" from Wikipedia. So, it makes perfect sense a private key is kept on the originating system and the public key is the one shared. And this message is repeated again and again:
However, instructions to set up NX From CentOS's FreeNX setup page (scroll down): "You will need to ssh into the server [...] Copy all the text (including the BEGIN DSA PRIVATE KEY and END DSA PRIVATE KEY lines."
From NoMachine's setup page: "Distribute the private key from the newly generated couple of keys located in the file [...] to all clients that have to be granted acccess to the specific NX server host."
The client can certainly generate its own private key.
EDIT: And... After trying to take the below comments into consideration, I reconfigured the user for nx. What's going on with the failed authentication asking for (what I expect) the public key?
