Problem Connecting to Linux Server

[James Weatherall]

Doug,

I suspect that the problem that you're having is that Xvnc Enterprise
Edition will default to using a secure connection, which requires that it
have access to a private key.  You therefore need to use vnckeygen to ensure
that the "nobody" user has a private key in their ~/.vnc directory.

You will also need to tell Xvnc not to authenticate the incoming connection,
by adding "UserPasswdVerifier=None", or to authenticate it against the user
accounts database on the system, with "UserPasswdVerifier=UnixAuth".

As a simple test to get started, you can use "SecurityTypes=None" on the
Xvnc command-line to tell Xvnc not to perform encryption or require
authentication.  This should allow you to connect & verify that the rest of
the setup is working.

Regards,
