[gentoo-user] NX* recommendation / help

[Helmut Jarausch]

Hi,

I have been using net-misc/nxserver-freeedition / nxclient for quite
some time and it was working great (over an DSL line)

But, some time ago, all of a sudden, it stopped working (some task died)

Can anybody give me some recommendations on

- HowTos
- use nxserver-freeedition or nxserver-freenx
- how to "clean" my system from any hangover of the
  old, non-working version

Many thanks for sharing your experience,
Helmut.

Here is what I did;
http://forums.gentoo.org/viewtopic-t-728963-highlight-.html

That was a while ago so check the elog for any new details. The only 
problem I ran across was that after an update I had to rerun;
nxsetup --install --setup-nomachine-key --clean --purge
I do not remember doing that lately so it may have changed.

Thanks, still I have a problem.

nxclient comes up and runs up to displaying
"Established the display connection"

But then, nothing happens (I don't a remote desktop),
nxclient terminates without any error message or entries
in some log files.

Any idea?

Helmut.

See if there is a clue in /home/user/.nx/S-*

Check in your user ~/.nx/ directory and delete old sessions... I had
the problem where NX would connect and then timeout before ever
loading a desktop environment. Deleting all of the old sessions fixed
it for me.

Thanks, but on one machine, at least, I get those errors messages which
are driving me nuts

NX> 203 NXSSH running with pid: 14256
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files

(I did nxsetup --clean --install --setup-nomachine-key --purge
and with nxclient I've set the key to 'Default'
I'm stuck.

Hi Helmut,

Be sure the "nx" user has a password set. Any password. It doesn't
matter what, as long as it has one. (it actually uses publickey so the
password is irrelevant, but sometimes it won't connect without one)

Otherwise I would double-check that your keys match. Check
/usr/NX/share/keys/default.id_dsa.key on the server and compare it to
the key you have in your nxclient.

Furthermore, if you have PAM authentication disabled in your sshd, you
need to use the internal user and password database and explicitly add
users and passwords to it. At least on my system that's what I had to
do.
