subject:"\[CentOS\] freenx"

hi,

this is not the same as http://bugs.centos.org/view.php?id=6298

I can login with ssh but not with freenx

With 6.3 this worked, I just spinned some new servers and now I can no
longer use freenx.

in /var/log/messages:

My node.conf file is a copy of the node.conf.sample file, nothing changed.
I do not want to use the nx database authentication but our ldap (ipa)
authentication., this has always worked until now.

I have temporarily set selinux in permissive mode but no difference.

Can anyone else reproduce this? At work we have a mirror, so I tried at
home with a manually installed centos and internet upgrades. No difference.

seems pretty obvious that the issue is here…

 NX 404 ERROR: wrong password or login

So the first question is can you SSH into the NX server system as user 'admin' 
with the same password? If you can then the problem is in /etc/pam.d/ but my 
money is that you can't and the issue isn't nx at all.

Re: [CentOS] freenx not working with newly installed centos 6.4

hi,

Thanks for taking the time to reply.

As stated in my message I can log in from ssh. And yes, the password is the
same, I have verified it numerous times.

So no, that is not the problem. And as I wrote in my first message, this
has always worked until 6.4. That is why I was asking if anyone else is
having this same problem with a new installed 6.4.

nx is unfortunately very difficult to debug.

Could there have been some crypto as the problem? Where did you install

Freenx defaults to generating a unique client.id_dsa.key - did you
install that in the client for each target?

hi,

thanks for taking the time to reply.

Yes, I copied the client key. I have followed the wiki instructions except

ENABLE_PASSDB_AUTHENTICATION=1

and adding the users to it with nxserver --adduser

because we are not interested in that, we use ldap users and that has
worked since like for ever, I no longer remember.

hi,

thanks for replying.

I live in The Netherlands, so I suppose the mirror was automatically chosen
in Europe at least. Sorry, I did not pay attention to that. Is there a
logfile where I can look that up? in yum.log I can only see that packages
get installed/removed.

[CentOS] FreeNX on Centos 5.7

2011-12-09 Thread Georgi Meyer

HI All,

I am new to Linux so please bare with me.

I am running Centos 5.7 with FreeNX-0.7.3-8.el5 and I have successfully
installed everything and configured my first user. However when I log in
using the NX Client I see the desktop however I don¹t have mouse or keyboard
access. Is there a setting I have to apply in order to get mouse and
keyboard access?

Thanks,

You'd need to provide more detailed information. How did you install
nx/freenx on the CentOS machine?  You are connecting from what OS?
Client software/version?

2010-10-13 Thread Tom Bishop

I use freenx and install it very frequently, I don't modify the sshd config
but go here to get a copy of the .ssh key...
/var/lib/nxserver/home/.ssh/client.id_dsa.key
and copy that to your client machine



in  fact if you want to generate a new key the comman is nxkeygen


see if that makes any difference

  You appear to have missed a step or configured the auth bits
 incorrectly. The NX user is the user who authenticates via ssh, and
 you authenticate via nx to the proper session. Go through the steps in
 the wiki again carefully and double check the logs to see who you're
 attempting to authenticate as. I'd bet you're trying to auth as your
 user instead of as the nx user and since the wiki states that only the
 nx user is authorized (via the AllowUsers nx statement) auth is
 failing for that reason.

 in  fact if you want to generate a new key the comman is nxkeygen


 see if that makes any difference

You shouldn't have to do anything but install the rpm and copy that key.  But, 
you should have an nx user that the rpm creates, and you may have to allow 
password authentication.  The client first connects with ssh as the nx user, 
using the key and no password, then passes your login and password over that 
encrypted connection - but I'm not sure if it uses ssh to authenticate with the 
password at that point.

 To ease remove the centos packages and install the RPMs from nomachine.com

The nx/freenx packages from CentOS should work if you follow the
instructions at http://wiki.centos.org/HowTos/FreeNX to the letter.
The only deviation you can have is that you can skip Section 2
(Key-based authentication) entirely *IF* your sshd is set up to allow
password authentication (PasswordAuthentication yes).

The most common error associated with authentication error is failure
of copying the content of client.id_dsa.key when setting up the
client.

[CentOS] FreeNX : forward audio from server to client ?

2010-03-10 Thread Niki Kovacs

Hi,

I setup a FreeNX server with a GNOME desktop, and I can access it from a 
client with the NoMachine client. Everything is running fine, and now I 
only have two problems left : audio and printing forwarding. I'll follow 
the only-slay-one-dragon-at-a-time rule and take care of audio first.

Did anyone manage to forward sound with FreeNX ? Here, server and client 
are using CentOS. And yes, I did check the little enable multimedia 
checkbox on the client, but to no avail. Whenever I play a sound in the 
client session, it comes out on the server speakers.

Any suggestions ?

I've had bad luck myself with sound - but using NoMachine...  And, for me 
it only seems to work where sound is played for a Windows client machine 
to a NoMachine CentOS server.  The only sound I can get is using XMMS... 
If I start a web browser (like Firefox), I do not hear anything if I go to

I'd love to know how to get sound working as well :)

I just managed to get it working. In GNOME, you have to select ESD

So, this machine does have a sound card (not sure that matters).  I used a 
different machine (no sound card) and was able to use XMMS and KDE - but 
not anything emitted from a Web browser.


Again, the CentOS machine does have a sound card - so sound works

I should say that the KDE machine - was running Fedora 12 with no sound 
card whatsoever.  Again, XMMS worked from the Fedora box back to a Windoze 
NoMachine client.  It didn't work to a Linux client (Fedora nor CentOS) 
that did have a sound card.


In both cases, the client machine didn't work when a web browser was 
involved - for example watching Youtube videos.

You don't need a soundcard on the server if setup with a dummy ALSA  
device.

You do need ESD or pulseaudio setup properly on the server/client as  
well I believe for NX to work.

Why Flash doesn't come over by default is because it uses OSS instead  
of ALSA, so in order to get that working you need the ALSA OSS  
emulator installed on the server.

Don't ask me how to do it, I am trying to forget even having tried it  
and when it was working quality was terrible and control was touchy.

Your definitely better using Fedora for the server here as sound  
support in CentOS stinks, but then again I don't use it for sound and  
video support.

Google Flash and ALSA and prepare to go down a rat hole on this.

[CentOS] FreeNX Shadowed Desktop issue

2008-11-14 Thread James Blackburn

Hi All,

I'm hoping someone will be able to offer some advice on desktop
shadowing with the latest CentOS 4's FreeNX.

I've installed the latest FreeNX RPMs as described on the wiki:
[EMAIL PROTECTED] ~]$ rpm -qa |grep nx
nxclient-3.2.0-9
freenx-0.7.3-1.el4.centos
nx-3.2.0-8.el4.centos

And I can NX in using two separate test user accounts.

However when I try to enable shadowing I encounter two problems:
1) The shadow selection dialog doesn't show usernames (the column is
simply blank).  The result is that you need to know the display number
in advance.
2) On choosing a display, I get an error connecting (and an
authentication request is never shown on the display being shadowed).

I can work around 2 by first doing 'xhost +' on the display which is
about to be shadowed.  But this isn't ideal...

Any ideas / tips / pointers to more documentation appreciated!

Cheers,

James

NXlog attached containing: 1 session created, followed by attempt to
shadow from another user account.

 Les,

 You can try the version of freenx here:

 If it all works well, we can release this version of freenx.
 
 Thanks! The i386 version installs OK, works at least as well as the

Glad that it works, it also seems to work for me on i386 and x86_64.

 However, I think I'm missing something about
 how to connect to a shadowed console session.  If I configure the client
 to use a vnc session, I can see it as vnc-local but haven't been able to
 connect even though I am connecting as the same user.  Do I need to set
 a password for this?  Is documentation for the new features available
 somewhere?
 

I do not know how to connect to a local vnc session using the NX client,
though I was going to look into that.  If I figure something out I will
post here, though I am not sure when I can look at it.

I think the 7.3 version was the first to include it.  It has been in the 
commercial NX versions for a while.  I think those are free to use with 
some connection limit but I haven't gotten around to testing it yet.


Another interesting capability is for the client to resize the whole 
remote desktop screen.  The Mac NX client seems to be able to do that 
arbitrarily where the windows version only does it sometimes to snap the 
desktop to the available window space - and sometimes not.  Does anyone 
know what controls this capability and how it will mesh with shadowing a 
desktop tied to another client or actual video hardware?

Done - but the bug tracker isn't very conducive to picking things in extras.

[CentOS] freenx vs vmware console

2008-07-17 Thread Les Mikesell

After upgrading to 5.2 and the current freenx, when I start the vmware 
server console (from VMware-server-1.0.6-91891) in the NX client I get

Xlib:  extension XFree86-VidModeExtension missing on display :1000.0.
in the terminal window where vmware was started and a black screen where 
the console of the virtual machine is supposed to be.  Is there a way to 
make this work?  I would normally ssh/freenx/vnc directly to the virtual 
machine but for the cases that need console access I would much rather 
use NX with the host machine with the vmware console conneced locally 
than use the vmware console remotely.

I have just installed freenx on two seperate centos 5.0 boxes. I had freenx

[CentOS] freenx

2007-11-13 Thread Michael Oevermann


Hello,

I am having problems getting freenx running in CentOS 4.5  i386_64. I  
know this is not a new problem, however, I havn't

found a solution in all the postings I found on the web.

I did exactly what is supposed to work and described in detail at

http://wiki.centos.org/HowTos/FreeNX

After doing that I can connect to the server with nxcleint without  
problem but I get only a black screen. In the files


.nx/S.../session  and errors

I see the warning

Warning: Unrecognized session type 'unix-gnome'. Assuming agent session.

The same happens with KDE.

With the command

nxloadconfig --check

I get the output

version of FreeNX.


  Errors occured during config check.
  Please correct the configuration file.


The libraries are definitely not where nx looks for them - they are  
located at /usr/lib64/NX/lib (and symlinks under (usr/lib/NX/lib).
What is going wrong here? I also tried to use nxconfig with --setup- 
nomachine-key with the same results, except that

I did not need to import the key in the nxclient anymore.

Does anyone has an idea to solve the problem?

Many thanks for help

Michael

Indeed, its a x86_64 cluster (more precisely 4 (master) + 16 (nodes)  
processor AMD Opteron machine with

freenx only running on the master). The installed versions are

nx-3.0.0-4.el4.centos.x86_64
freenx-0.7.1.svn416-2.el4.centos.x86_64.

CentOS-4 has been install from scratch

Mogens,

thank you for your reply, but I did this already before sending an email to the centos mailing 
list. Now when starting the nxclient on my workstation, I get a message presenting some dead 
available sessions which cannot be resumed. Only clicking New in this prompt will continue with 
opening a session.


This happens on each nxclient start.

 which cannot be resumed.

 This happens on each nxclient start.

The dead sessions, except the one that says X0 (local),  are probably
just leftovers in this directory:

/var/lib/nxserver/db/running/

You can make sure all your current NX sessions are exited on the server,
then go to that directory (/var/lib/nxserver/db/running/) and if there
are files in there, remove them (or back them up to another directory if
you want to be extremely cautious :D ).  Also look in
/var/lib/nxserver/db/failed.  The older versions of freenx tended to
leave connections there after they were dead, but not show them to the
client.

The X0 (local) session shows up all the time, but can only be connected
to IF you are sharing your desktop via VNC.  Most of the time, this will
not be the case, so just ignore it.

 Only clicking New in this prompt will
 continue with opening a session.

Do these new sessions behave properly for you (can you disconnect and
reconnect to them properly from the same client)?

Thanks,
Johnny Hughes

then go to that directory (/var/lib/nxserver/db/running/) and if there
are files in there, remove them (or back them up to another directory if
you want to be extremely cautious :D ).  Also look in
/var/lib/nxserver/db/failed.


Is empty too.

The older versions of freenx tended to

leave connections there after they were dead, but not show them to the
client.

The X0 (local) session shows up all the time, but can only be connected
to IF you are sharing your desktop via VNC.  Most of the time, this will
not be the case, so just ignore it.


Only clicking New in this prompt will
continue with opening a session.


Do these new sessions behave properly for you (can you disconnect and
reconnect to them properly from the same client)?


These new sessions behave properly.

Additionally, I had no problems with the previous NX version.

 thank you for your reply, but I did this already before sending an email
 to the centos mailing list. Now when starting the nxclient on my
 workstation, I get a message presenting some dead available sessions
 which cannot be resumed.

 This happens on each nxclient start.

 The dead sessions, except the one that says X0 (local),  are probably
 just leftovers in this directory:

 /var/lib/nxserver/db/running/
 
 This dir is empty! And no session is/was running.

Maybe you have these in the NoMachine client's location instead:

/usr/NX/var/db/

failed and running directories ... the entries you want to delete will
look something like this:

I found such entries, but deleting them was not helpful.

Still getting the prompt I have attached.

Right ... that one connection is the X0 (local) connection, that is
your normal local desktop shared.

You will normally not be able to connect to that, and it can be ignored.
 (Unless you are logged in and have set vino to share your :0 desktop)

Hi Johnny,

thank you for the explanation. Clicking in this additional prompt (which now appears each time) on
the New button seems be the only solution.

I thought the current version from NX was able to share the console 
session too.  Does anyone know if that is planned for freenx?

 Right ... that one connection is the X0 (local) connection, that is

is there any way to get rid of this session? it keeps confusing my
colleagues, so it would be very nice if it could be convinced to
disappear.
