I have installed freenx with this article
http://wiki.centos.org/HowTos/FreeNX
but when I use freenx-client on windows to connect to server, I always get an "freenx Authentication failed."
client err log output as this: NX> 203 NXSSH running with pid: 1584 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files NX> 285 Setting the preferred NX options NX> 200 Connected to address: 192.168.253.5 on port: 22 NX> 202 Authenticating user: nx NX> 208 Using auth method: publickey NX> 204 Authentication failed.
My sshd configed as use rsa key, and ssh soft like xshell can work well.
nxsetup output as this: Pleas care the following red commented two line. I just think this is the point. But why , and what shoud I do to solver ?

Fatal error: Could not connect to NX Server. Please check your ssh setup: The following are _examples_ of what you might need to check. - Make sure "nx" is one of the AllowUsers in sshd_config. (or that the line is outcommented/not there) - Make sure "nx" is one of the AllowGroups in sshd_config. (or that the line is outcommented/not there) - 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. (this should be a filename not a pathname+filename) - Make sure you allow ssh on localhost, this could come from some restriction of: -the tcp wrapper. Then add in /etc/hosts.allow: ALL:localhost -the iptables. add to it: $ iptables -A INPUT -i lo -j ACCEPT $ iptables -A OUTPUT -o lo -j ACCEPT [root@tigertall ~]#
Thanks you!
