I am running CentOS 5.5 in command line only. Reason being I am standing up an IDS system on it.

I have installed the NX client/node and server pkgs. I have installed the NX client for windows on a Vista box. When I attemtp to connect from the Vista to CentOS, I get this:

NX> 203 NXSSH running with pid: 22080 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: 192.168.1.70 on port: 22 NX> 202 Authenticating user: nx NX> 208 Using auth method: publickey NX> 204 Authentication failed.

Now I have been googling and re-googling. Plenty of people have had the same issue, but I have yet to find a solution that works for me. Funny that most of the stuff I'm finding on google is 4-5 years old! I'm sure I am probably missing something so simple I will puke!

I think I read that someone did an install and it worked right out of the box!! Incredible!

I'd really like to see a CentOS - NX configuration guide but couldn't find one.

Can someone just tell me how this should be configured....what changes do I need to make and to what config files?

ssh (putty and WinSCP) works just fine for me in case you need to know.

If you need any particular information, please let me know.

Thanks.

---- usually when that happens, that means you didn't copy the client.id_dsa.key from /etc/nxserver to the client and set that key in the client setup.

NX authenticates as the nx user via ssh keys to get an encrypted connection to pass the real user credentials over. The commercial NX server always uses the same key as the client, but freenx (at least as packaged in epel or centos-testing) generates a unique key per install. So you have to get the contents from /etc/nxserver/client.id_dsa.key into the client config for each target host. You can do this by copying the file with winscp and importing it with the NX client gui Click the 'configure', then the 'key' buttons to get to the right place. Or you can use putty, cat the file to get the text on the screen and copy/paste it into the dialog box, replacing what is there - keeping the ---begin and ---end lines.

It should come up working - but you can copy the node.conf.sample to node.conf and edit it and/or run /usr/bin/nxsetup again if you want to change any options.

These connect directly as the user - for NX, you need an nx user that should have been installed by the package.
