FreeNX running failed

[Soo-Hyun Choi]

Hi,

I have built FreeNX from the source as directed by
http://stateless.geek.nz/2005/06/27/building-freenx-04-on-ubuntu-hoary/.

After installation, I ran 'sudo nxsetup' and got the following error message.

soohyunc at quokka:~ $ sudo nxsetup
------> You did select no action.
        FreeNX guesses that you want to _install_ the server.
        Type "y" to abort the installation at this point in time.
        "N" is the default and continues installation.
        Use "/usr/sbin/nxsetup --help" to get more detailed help hints.

 Do you want to abort now? [y/N] n
------> It is recommended that you use the NoMachine key for
        easier setup. If you answer "y", FreeNX creates a custom
        KeyPair and expects you to setup your clients manually.
        "N" is default and uses the NoMachine key for installation.

 Do you want to use your own custom KeyPair? [y/N] ySetting up

Are you sure you want to continue connecting (yes/no)? Fatal error:
Could not connect to NX Server.

Please check your ssh setup:

        - Make sure "nx" is one of the AllowUsers in sshd_config.
        - Make sure your sshd allows public key authentication.
        - Make sure your sshd is really running on port 22.
        - Make sure your sshd_config AuthorizedKeysFile in sshd_config
is set to authorized_keys2.

What would be the problem in this case? I have checked that my sshd
allows Public Key authentication running on Port 22, and
AuthorizedKeysFile is set to authorized_keys2.

Thanks,
