I have found an old (1.5) version of the nxclient that will run on FC2 machine and am now trying to get the connection working. I can authenticate into the NX account on the server machine and the NX server starts but it doesn't seem able to get an SSH link to localhost. It says: NXSERVER-3.2.0-7[5875]: ERROR: Failed authentication. NXSsh exit status is:255 'NXNssUserManager::auth' NXSERVER-3.2.0-7[5875]: Failed SSHd authentication for user 'jonathan', to '127.0.0.1', port '22': 'NX> 204 Authentication failed.\n ' 'NXNssUserManager::auth' NXSERVER-3.2.0-7[5875]: ERROR: Error while trying to authenticate user:jonathan. NXNssUserManager::auth returned 255 'NXShell::handler_login' NXSERVER-3.2.0-7[5875]: ERROR: failed 'sshd authentication' for user 'jonathan' from '83.104.103.142'. NXShell::handler_login NXShell 373 Is this because the server machine's ssh configuration is only to accept rsa/dsa authentication and not password ? How can I make the key available to NX ? Jonathan
