Hi everybody, I'm having troubles with getting freenx setup on one of my RHEL6 servers and I'm at a loss on what to try next. I have FreeNX and NX both installed, but when I run 'nxsetup —install' to setup the standard keys it says that the connection to the nxserver is bad and it fails. The output is the same as what is below. I tried all of the suggestions that are given in the output as examples of what to try, but none of them made any differences. Strangely, I have freenx setup on other servers where it does work and 'nxsetup —test' outputs the same errors until where it gets to '<--- done'. This server is under the same puppet control as the other servers that work so all the configuration files are the same. One thing that I think could be a cause is that the other working servers were kickstarted when the OS was installed, but this server's OS was installed manually so maybe somewhere a config file is different that I missed. Any help is much appreciated, thanks! Nick Here's the output from nxsetup —test: [root@itf-matlab03 .ssh]# nxsetup --test ----> Testing your nxserver configuration ...
