Hi,
Basically nx works by logging in via ssh as the "nx" user which has
nxserver for it's shell.
You can either use the nomachine key (preinstalled in the client)
or change this key.
As with all ssh based things - you can have multiple
keys for the same nx user. - in fact you can use the existing keys. Just
grab each users ~/.ssh/authorized_keys file and put it into the
~nx/.ssh/authorized_keys - then tell the user to paste their private key
into the nx client )
Once the nx client logs in via nx at hostname the nxserver script can either
use ssh (using passwords) or su (using passwords) to actually login as
the user.
If you want nx without this then you can not use the no machine client you
will have to use nxnode directly. (more complex)
nx is not really equal to ssh BUT it does use ssh.
