A solution I found to the “The NX service is not available or the NX access was disabled on host xxx.xxx.xxx.xxx.” error is to use the key below in my clients

/var/lib/nxserver/home/.ssh/client.id_dsa.key

But at first I was using the key fabio is using above then after a reboot I had to use this key to connect.

I am running freenx on ubuntu 9.04 amd64 server. I have 8 or so clients that connect using nx client from nomachines. There is a mixture of client oses – windows xp (mostly), mac, ubuntu.

This has happened to two different users: everything was working great, and then one day the nx connection timed out.

When it does not work it does not work from any client computer, so I don’t think the client nx program is the problem.

The latest versions of freenx server and nomachine client are installed on the server and on the client machines.

Has anyone else had a problem like this? Any suggestions?

the problem with nx server not being available most of the time is related to wrong permissions on the key files and authorized_keys (or authorized_keys2) files.

here is what you have to do:
chmod 755 /var/lib/nxserver
chmod 755 /var/lib/nxserver/home
chmod 755 /var/lib/nxserver/home/.ssh
chmod 600 /var/lib/nxserver/home/.ssh/authorized_keys

chmod 600 /var/lib/nxserver/home/.ssh/authorized_keys2

chown nx /var/lib/nxserver/home/.ssh/authorized_keys2

or
chown nx /var/lib/nxserver/home/.ssh/authorized_keys

depending on your server’s sshd configuration!

after that, if you add your own id_dsa.pub to authorized keys:

1) generate your key :
cd ~/.ssh
ssh-keygen -t dsa
(press enter few times as answers to questions)
you will have two files there:
id_dsa and id_dsa.pub

copy the content of id_dsa.pub

ssh as root to your server machine (the one running nxserver) and copy and paste that into

/var/lib/nxserver/home/.ssh/authorized_keys
or
/var/lib/nxserver/home/.ssh/authorized_keys2

(depending which file is being used by sshd )

I solved this problem!

I installed Ubuntu 9.04, and Remote Desktop stuff worked without a hitch right off the bat.

Probably not the fix you were looking for, but there it is. Works for me.

@Knu-o2,

Have you tried rebooting the fedora 11 machine ?

Tell nx to install new key:

/usr/libexec/nx/nxsetup –install –setup-nomachine-key

I’m running Fedora 11, and am having same problem as DaveyBob. I am as sure as I can be that I have copied the correct key over to the Windows Nomachine client. But still I get “The NX service is not available or the NX access was disabled on host xxx.xxx.xxx.xxx.”

Anybody got a clue?

I’m running Fedora 10, and this was working until recently. Apparently, some update hosed it. I completely uninstalled freenx and nx, and reinstalled it following your directions, but I get the same result: NX server is not available blah blah blah.

This is driving me nuts…
