load balancing freenx

I'm trying to get load balancing working. with three machines
HostA (10.0.0.2) is the load balancer, HostB and HostC are the
other machines (10.0.0.3 and 10.0.0.4 respectively) These addresses
are in /etc/hosts of all three machines

On HostA, I enabled
LOAD_BALANCE_SERVERS=" HOSTA HOSTB HOSTC"
LOAD_BALANCE_ALGORYTHM="load"

On the other two machines, I have

LOAD_BALANCE_SERVERS=" HOSTA HOSTB HOSTC"
LOAD_BALANCE_ALGORYTHM="load"
ENABLE_SERVER_FORWARD="1"
SERVER_FORWARD_ADDRESS="10.0.0.2" # (HOSTA)

Do I also need SERVER_FORWARD_KEY on the other two hosts?
Should this key be copied from hosta:/etc/nxserver/client.id_dsa.key?

Thanks

It's probably associated with your distro,
though
it may well be community maintained now
( mainly compiling the libraries when nomachine
 update their open source code )

Suse seemed to have lost interest,
ubuntu did something last year for "precise" ( whatever that was )
and
I think they got updates from ALT-linux in Russia, who did quite a bit of work
but
as Akemi seems to be still keeping Fedora (RHEL Centos) etc going
I would choose that one I guess . . .

It isn't . . .

Technically I think its 3.3 (from 2008) but i'm not sure how they labled
 each script and mine says the same.

The Ubuntu people upped theirs a version, but there isn't much different
just patches for things which moved . .

I've got most of the various bits going and put patches in freenx-knx
so if it was all gathered together then it would all work now
but
not many people are interested in the more obscure facilites
and
nomachine are ending support for the libaries

Which distro are you using ???

gateway not working with loadbalancing and multiple servers

Hi!

I have set up a gateway, master and two nx-servers.
I can connect to both servers.
I can connect to the master an being forwarded to one of the servers.
I can connect to the gateway, but this times out.

The gateway has (10.167.63.124):
ENABLE_SERVER_FORWARD="1"
SERVER_FORWARD_HOST="10.167.63.127"
SERVER_FORWARD_PORT=22
SERVER_FORWARD_KEY="/var/lib/nxserver/home/.ssh/client.id_dsa.key"

The master has (10.167.63.127):
LOAD_BALANCE_SERVERS="10.167.63.125 10.167.63.126"
LOAD_BALANCE_ALGORITHM="round-robin"
ENABLE_LOAD_BALANCE_PREFERENCE="0"

The nodes have (10.167.63.125; 10.167.63.126):
ENABLE_USERMODE_AUTHENTICATION="0"
ENABLE_PASSDB_AUTHENTICATION="0"
ENABLE_SSH_AUTHENTICATION="1"
ENABLE_SU_AUTHENTICATION="0"
ENABLE_PERSISTENT_SESSION="all"
ENABLE_MIRROR_VIA_VNC=1
ENABLE_DESKTOP_SHARING=1
ENABLE_SESSION_SHADOWING_AUTHORIZATION=1
ENABLE_INTERACTIVE_SESSION_SHADOWING=1
ENABLE_CLIPBOARD="both"
ENABLE_PULLDOWN_MENU="1"
NX_LOG_LEVEL=2
NX_LOG_SECURE=1
NX_LOGFILE=/var/log/nx/nxserver.log

On all servers I've set in /etc/ssh/sshd_config:
AuthorizedKeysFile      .ssh/authorized_keys
AuthorizedKeysFile2     .ssh/authorized_keys2

On all servers I can login using the key defined in .ssh/authorized_keys2 with ssh and user nx (I am thrown out again immediately, because of protocol violations if connecting with telnet, but ssh is working and does what is expected).

I can connect with nx-clients to both nodes. A session is established.

I can connect with nx-clients to the master. A session is established to on of the nodes.

I can connect with nx-clients to the gateway, but no session will be established. Instead the client times out:
NX> 203 NXSSH running with pid: 5460
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: 10.167.63.124 on port: 22
NX> 202 Authenticating user: nx
NX> 208 Using auth method: publickey
NX> 280 Exiting on signal: 15

If starting a sshd in debug mode it shows the client connecting, then sits there and waits for the master. After a while it kills the connection.

seLinux was turned of. The firewall is turned off too.
I am a bit clueless now. Any idea how to make this run? Or some idea to get rid of the gateway and leave this part up to the firewall?
But I'd like to know why this breaks at the gateway. As all docs state it should work out of the box ...!

FreeNX Error: Call to bind failed for font TCP port 12001

Hi All,

As of recently, I cannot use FreeNX to connect into one of my servers.  When I try to connect using FreeNX, I get the following error:

Error: Call to bind failed for font TCP port 12001. Error is 112 'Address already in use'.

I don't believe I've changed anything to cause this problem.  I rebooted the server to see if that would clear the NX error since it normally does when something strange happens.  Unfortunately, rebooting did not fix the issue.  I still get the same error.  Does port 12001 need to be open for TCP and UDP incoming and outgoing connections?  I would assume the traffic is local since it already passed SSH authentication and tried to create the session.   

I used netstat, and I didn't see anything using port 12000 or 12001.  Any ideas on what I should try / do?

Thanks!

Hanging at resume

Hi all,

I spent a couple of hours yesterday and finally .... I got FreeNX
working :) together with the official NX client 3.5 on Windows.

Server is an Ubuntu rary without root privileges and I set up for usermode.

It works more or less ... but about every 2nd reconnection fails.

The errors I get after resuming are:

NX> 1000 NXNODE - Version 3.2.0-73 OS (GPL, NX4U Edition, using backend:
3.2.0)
NX> 700 Session id: server-1006-21984185F28736130A049345234FC3A5
NX> 705 Session display: 1006
NX> 703 Session type: unix-application
NX> 701 Proxy cookie: 98968970197b585bd49a15cf65e19570
NX> 702 Proxy IP: *
NX> 706 Agent cookie: 98968970197b585bd49a15cf65e19570
NX> 704 Session cache: unix-application
NX> 707 SSL tunneling: 1
NX> 596 Error: Session restore failed. Reason was: Session: Display
failure detected at 'Mon Nov 11 23:10:44 2013'.
NX> 1001 Bye.

or, after the second time:

[...]
nx 1004 error session did not start.
nx 596 session resume failed

or

1009 Session status: suspending
NX> 1009 Session status: suspending
NX> 1009 Session status: suspending
[...]

Or just:

NX> 1000 NXNODE - Version 3.2.0-73 OS (GPL, NX4U Edition, using backend:
3.2.0)
/home/luke/NX4U/bin/nxserver: line 1547: 32452 Terminated
sleep $AGENT_STARTUP_TIMEOUT
NX> 105 NX> 596 Session startup failed.

I tried to debug for hours but now I am on my end. The essential problem
is that nxnode times out without any more error messages other than the
one above. The log does not contain error messages either.

Based on that I just tried to execute manually to debug it. But there is
no output other than that and afterwards it hangs:

echo
'&rootless=1&virtualdesktop=0&application=xterm&link=lan&backingstore=1&encryption=1&cache=16M&images=64M&shmem=1&shpix=1&strict=0&composite=1&media=0&session=corn&type=unix-application&client=winnt&kbload=pc102/en_US&keymap=en_US&keyboard=pc102/en_US&aux=1&id=21984185F28736130A049345234FC3A5&virtualdesktop=1&clientproto=&user=luke&userip=xxx.xxx.xxx.xxx&uniqueid=21984185F28736130A049345234FC3A5&display=1006&status=Suspended'

NX> 704 Session cache: unix-application
NX> 707 SSL tunneling: 1

Any ideas? Any ideas where I could continue debugging?

Any help/hints greatly appreciated!

Thanks
luke

Release: FreeNX 0.7.3 "Priscilla One Year Edition"

Dear Fabian,

I wonder if I could ask you a quick question relating to FreeNX?

Back in 2012 there was a mail on kde.org relating to FreeNX:
http://mail.kde.org/pipermail/freenx-knx/2012-July/009691.html

It concerned resuming suspended sessions when connecting to FreeNX (nxserver) from a machine running NX
Player - basically you couldn't connect to resume the session……

Later in the thread there is a post by Nich Couchman who supplied a patch:
http://mail.kde.org/pipermail/freenx-knx/2012-July/009695.html

Unfortunately the patch seems to relate to a different nxserver script, so we aren't able to apply it.

Please can you let me know if this solution really worked, and is worth pursuing, or if there is some other
version of FreeNX out there which we don't know about :-)

FYI we have nxserver version 3.2.0-74-SVN installed on Ubuntu 12.04 LTS

Any help you can provide would be much appreciated.

Yours,

Jon

Nomachine 4 out....

Hi,

Apparently the commercial version of Nomachine 4 is out. I installed the 
new client for RHEL6 and the first impression was not good at all.

I would like to start saying that I have 2 NX servers which are used as 
"bridges" to connect to other servers, so the users can't SSH into these 
NX boxes, they cannot open local terminals and access local files, they 
can just open terminals to other machines. This is done with a custom 
Fluxbox/NX configuration. One of the servers has the FreeNX version, one 
of the has the 3.5 commercial version.

So, everything worked fine with the old client but the new client does 
not work well at all, I suggest other people to test it against your 
installations.

* The GUI is a mess. Totally bad design.
* At the first login to the server with the 3.5 commercial server 
version, I got a rootless terminal to the NX server itself, and I 
couldn't see  the Fluxbox desktop at all. This is a security problem for 
my setup.
* Then I opened Matlab, closed the session and when I logged it again 
the image and resolution was totally messed up.
* I closed the session, opened it again, and this time I could see the 
Fluxbox desktop as it was supposed to be!
* After this it always showed the Fluxbox desktop.
* Resizing the window does not work well, the image becomes "dirty" with 
some strange lines and pixels which should not be there.
* Now when I log in it says that there's a guest connected to my 
session, with my own username.
* I tried to connect with the new client to my old FreeNX servers, and 
it didn't work at all, I'm not sure if it's because of my configuration 
or because of some block they implemented to cut out the opensource version.
* I couldn't find

I will contact the Nomachine support about these issues, but I doubt 
they will be able to fix these issues any soon.

Please share your experiences with the new client!

Marco

FreeNX is alternatives

Hi,

I found this software: http://xpra.org/
How well does it compare to FreeNX? Does anybody have some practical 
experience with it?
So far I couldn't find any good alternative to FreeNX, but this Xpra 
might be worth checking out.

More Trouble with NX 4 Client -> FreeNX

Several months ago I posted on connection issues I'm having with NoMachine 4 clients connecting to FreeNX
(NX 3.5) servers.  I continue to have these issues, and, for various reasons, am still trying to get it to
work (rather than pursuing options like X2Go).  It's a long story, but I really would like to get this working.

The issue I'm having is that the connections from NX 4 clients to FreeNX work about 1 out of every 10 tries.  The
rest of the time, the connections fail.  There's something in the start-up/negotiation of the session
that is causing problems.  The last time I asked about this all I had was the error "Failure to negotiate at
stage '10'" or something along those lines.  I've managed to make a little more progress in tracking down
the problem.  The problem appears to be with nxagent and/or nxproxy shutting down prematurely.  Since this
only happens with NX 4.0 clients, I can only assume that something timing-wise or one of the options that
the NX 4 clients are causing the nxagent binary to crash.  I've further traced it down the nxcomp (libXcomp)
library and something that's happening in there.  I was able to recompile the library with lots of
tracing/debug turned on and get some more useful output.  At least, it'd be useful if I knew how to interpret
it.  I've attached the session "errors" file (gzipped to minimize size) from one of the sessions - perhaps
someone can take a look at it and help me make sense of it, especially to see where it's failing?

Thanks,
Nick

CentOS 6.4 FreeNX Session - Cannot open display

Hey All,

When I am logged into a FreeNX Session on my CentOS 6.4 server, I keep getting an error message when trying to run commands that load applications.  For example, if I run

sudo nautilus

I get this output:

No protocol specified
Could not parse arguments: Cannot open display:

The display variable shows:

echo $DISPLAY
:1000.0

It's not just nautilus.  If I try to launch virt-manager, I get this output:

sudo virt-manager
No protocol specified
Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-manager.py", line 383, in <module>
    main()
  File "/usr/share/virt-manager/virt-manager.py", line 286, in main
    raise gtk_error
RuntimeError: could not open display

Pretty much any GUI application I try to call from the terminal fails because it could not open the display. 

Any idea what I should do?  I tried this from the CentOS FreeNX article (http://wiki.centos.org/HowTos/FreeNX):

Solution: Edit /etc/nxserver/node.conf and change the line:

#AGENT_EXTRA_OPTIONS_X="-nolisten tcp"

to:

AGENT_EXTRA_OPTIONS_X="" I really need to be able to launch these GUI applications from a FreeNX session.  My separate Ubuntu server has no problems accessing the display in FreeNX sessions.  All help is appreciated.
