Unable to open display nx/nx,product=Neatx-GPL... about neatx

[GoogleCodeExporter]

Maybe this will help:

In the dir
/usr/local/var/lib/neatx/sessions/00EAD27D7090C8E308A5160C1620CA12/C-
descent.temple.stunet.ru-294-00EAD27D7090C8E308A5160C1620CA12
i have found a file which says:
Couldn't open RGB_DB '/usr/X11R6/lib/X11/rgb'

P.S. Forgot to tell, that I should have made the dir /usr/local/var/lib/neatx/
sessions/ writable by everyone (made it rwxrwxrwt) to bypass the corresponding 
error.

Can you enable debug logging for neatx please? If you look in the neatx config 
file
(only recently documented in INSTALL), you'll find a '# logging = debug' line 
that
needs to be uncommented. Thanks.

kormat, do you have any comments? It still does not work

I'm afraid i'm rather lost as to why nxagent is dying. Can you confirm that
/usr/local/var/lib/neatx/sessions/A4175EA36091E63680A96786E0ED87A2/neatx.data 
exists etc?

One thing i just noticed is the DeprecationWarning from your first log. I've 
sent a
patch out for review to fix that, not sure whether it'll make things work for 
you though.

Also, I can confirm that

exists
and looks reasonable.

I'm pretty sure the md5 Deprecationwarning has nothing to do with the problem. 
The neatx.data files exist. 
Don't know where too look at next.

@baranovich

That does look like the same problem alright, though you have an additional one:

Jul 15 17:04:15 sorberd-dev-box nxnode[32763]: DEBUG daemon:456 /usr/bin/xrdb 
stderr:
/usr/bin/xrdb: No such file or directory

xrdb is not installed, or the path is wrong.

Are all you folks running into this issue on ubuntu 9.04?

Original comment by kormat on 16 Jul 2009 at 7:34

[GoogleCodeExporter]

Hmmm... I do (at least now) have xrdb installed and I'm getting the same error. 
I
think I might have installed it since yesterday, as I have been fooling with 
neatx a bit.

I am running Ubuntu 9.04 amd64.

I also noticed that my client (which is running on win xp in a VM on the same
physical box) is giving me this:
"Could not find ':' in DISPLAY:"

even though the DISPLAY environment variable looks like it contains a ':' to 
me...
$ echo $DISPLAY
:0.0

Not sure if the above is related, but I figure it might help someone discover 
what's
going on.

I've tried to reproduce this on ubuntu 9.04 32bit and 64bit, no luck so far. 
Can you 
guys confirm that you're running the latest revision from svn (currently r19), 
just in 
case any fixes have gone in since that make it work now? 

Original comment by kormat on 20 Jul 2009 at 5:14

[GoogleCodeExporter]

With the latest svn, which probably added some more debugging output to syslog, 
I 
think I figured out what the problem was. Though I don't know how to solve that 
normally.

nxagent was saying: refusing connection from 192.168.69.130, which is one of my 
local IP's, and in it's cmd arguments was only accept=127.0.0.1.

If I launch 2 python programs like these:
>>> s = socket.socket()
>>> s.bind(('localhost', 10000))
>>> s.listen(1)
>>> s.accept()

>>> import socket
>>> s = socket.socket()
>>> s.connect(('localhost', 10000))

The first one outputs
(<socket._socketobject object at 0x7f51d1c23c90>, ('192.168.69.130', 59935))

So the "client" address is always this one 192.168.69.130, and not 127.0.0.1

I don't know how to fix it, and why this happens. Adding a route to 127.0.0.0/8 
through loopback interface did not help.

I hacked the agent.py file, and changed the "accept" line there to this address 
and 
finally I had the client run and connect successfully, though freezing after 
several 
seconds, but that is definitely another story.

Original comment by [email protected] on 20 Jul 2009 at 6:15

[GoogleCodeExporter]

still the "old" version, hacking the agent.py did not change anything, nither 
did some 
hacking via /etc/hosts, moving the localhost or hostname around (letting 
"localhost" 
resolve to the external or lo-IP).

might be able to update the next days.

It's the kernel that's filling in the network interface's IP address when 
accept(2)
returns the peer's address instead of the 127.0.0.1 that you'd expect from your
sample Python scripts.  Does the output of `ifconfig -a' and `netstat -rn' give 
any
clues?

This is really weird. Can you guys paste the entire logs for one attempt, 
please?
(The first entry is something like this: nxserver-login-wrapper[3501]: Started).
There might be some context in the logs that i'm missing. Thanks.

Ok, i think we have a number of different issues here.

@baranvich:
Your session failed because of this:

Jul 23 10:34:58 sorberd-dev-box nxnode[3555]: DEBUG daemon:456 /usr/bin/nxagent
stderr: /usr/bin/nxagent: error while loading shared libraries: 
libXcompext.so.3:
cannot open shared object file: No such file or directory

That means nxagent is missing one of it's main libraries, and isn't able to 
start. 
This is a different error to what you had before, have you maybe changed 
something?


@descentspb
Nxagent refusing a connection from a wrong IP is a different issue to the 
original 
one you were having. I'm rather baffled by it. The connection nxagent sees 
comes from 
netcat, run by nxserver. You could try telling nxserver to always run netcat 
against 
localhost, to see if that changes anything. In lib/app/nxserver.py, change line 
719 
from:

  args = [constants.NETCAT, "--", host, str(port)]

to:

  args = [constants.NETCAT, "--", "localhost", str(port)]

and see if that makes any difference.


@desoxyrebonukleinsaure

Thanks for the log, i don't immediately see what could be causing the problem 
i'm 
afraid. I'll go back over it most closely when i get a chance. Can you try 
running 
this please, and tell me what happens:

  nxagent -R -display nx/nx,link=modem:8 :2

Thanks.

Steve

Ah hah. Ok. I'm afraid the problem so is with your version of nxagent, as far 
as i
can tell. For comparison, here's what should happen when you run that:

diamond@asher:~(0:0)$ nxagent -R -display nx/nx,link=modem:8 :2

NXAGENT - Version 3.3.0

In your case, nxagent is exiting before it even gets to the waiting stage.

Does /tmp/.X11-unix exist, does it have these perms?

about libXcompext.so.3:

i also had these problems with the libraries, but through 

ldd /usr/NX/bin/nxagent

I figured out, which ones exactly it could not find, and made links to 
corresponding 
libraries from /usr/NX/lib in /usr/local.
I tried also to put /usr/NX/lib into /etc/ld.so.conf, but some system binaries 
failed to start after that

@kormat:

sorry, mate, I am willing to help solve that issue, but I should leave for a 
couple 
of weeks, and I will be left without any internet connection for that time.

As about library linking, I suggest that you should start nxagent with 
LD_LIBRARY_PATH environment variable set to e.g. /usr/NX/lib

It looks like this or an closely related issue was present in Fedora with 
freenx:
https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=503822

I don't quite understand yet how they solved it and a quick try of the suggested
workaround didn't show any result.

Original comment by [email protected] on 27 Jul 2009 at 9:11

[GoogleCodeExporter]

If 'nxagent -R -display nx/nx,link=modem:8 :2' doesn't work for you (i.e. exits
immediately with an error), then there is a problem with your nxagent, and neatx
cannot work. I'm afraid i've no idea what that problem is, or how to fix it, 
and as
it isn't related to neatx, i don't have enough time to try and dig into it (nor 
can i
reproduce it myself).

@descentspb

If you use NoMachine's nxagent binaries, then yes, you'll need to do some 
fiddling
with LD_LIBRARY_PATH. That's not explicitly supported by neatx, but should be 
trivial
to do. The simplest thing would be to use a small shell script wrapper around
nxagent, that sets the LD_LIBRARY_PATH, and then exec's the real nxagent with 
the
arguments it was passed.

Original comment by kormat on 29 Jul 2009 at 6:11

i am experiencing the same problem - nxagent -R -display nx/nx,link=modem:8 :2 
- 
fails with "Error: Aborting session with 'Unable to open display 'nx/
nx,link=lan:8''.".

this is 3.3.0 nxagent, compiled from the sources. error message is extremely 
uninformative, and i've been unable to find any more debugging - any hints on 
that, 
maybe ?

at http://www.nabble.com/nxagent---unable-to-open-display-:-(-td11321268.html 
i've 
found a hint to "Replace all occurrences of "DISPLAY=unix:$display" in nxnode 
with 
"DISPLAY=:$display"."
that didn't help, because i couldn't find anything like that in neatx code :)

on the redhat report at https://bugzilla.redhat.com/show_bug.cgi?
format=multiple&id=503822 the workaround suggested was "run 
/usr/libexec/nx/nxnode --
agent as root", which, i guess, also isn't applicable.

i'd appreciate some bright ideas on this issue :)

Original comment by [email protected] on 5 Aug 2009 at 2:10

[GoogleCodeExporter]

The biggest problem is that i can't reproduce this issue myself, making it very
difficult to figure out what's going wrong. Can you maybe try this:

  strace -o nxagent.strace -F nxagent -R -display nx/nx,link=modem:8 :2

The nxagent.strace file generated might point out something going wrong (it'd 
be best
to attach it to the bug, rather than pasting, it's likely to be very long)

arrgh. i have solved this particular problem.

i did not have nx-X11/lib/X11/libX11.so in LD_LIBRARY_PATH for nxagent, so it 
was 
using system libs and crashing in such a mysterious way.

I think I'm seeing the same error as descentspb and baranovich - which I think 
is due
to a broken pipe involving xrdb.  I have attached the server log file -
NXLoginAttempt3.log - and the message from the Nomachine NXClient on the client
machine.  
I am running Debian Squeeze on both machines, and the 3.4.0 series of Nomachine
files.  I followed the descriptions in
http://people.binf.ku.dk/~hanne/b2evolution/blogs/index.php/2009/09/01/neatx-is-
the-new-black
to install.  
When I try "nxagent -R -display nx/nx,link=modem:8 :2" on the server, the 
session
aborts with 
Xlib: connection to "localhost:10.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
According to your comment #30, this is an nxagent problem, and I understand 
that you
don't support nxagent.  Any suggestions where to turn?  I've searched the 
Nomachine
knowledge database without success.

@Jown_WPA: i think you have a different issue. The error you get from running 
nxagent
manually sounds like an xauth issue, not an nxagent issue. Looking at your 
logs, i'm
wondering if we're trying to run xrdb too soon after nxagent startup. I'm 
attaching a
patch which will fix that, if it's the problem.

I tried your patch, and things progressed a bit further, but I was still unable 
to
get Neatx running.  The problem seems to have more to do with nxagent than 
anything
about Neatx, insofar as I can judge.  I dropped back to Debian Lenny and 
version 3.3
of the Nomachine codes, and now have Neatx running on my server.  This more than
satisfies me, at least until the end of this semester.  Thank you for your help,
sincerely.

For the record. The solution for this is to have the libraries in the
LD_LIBRARY_PATH, yes, but how to do that is explained nicely here:
http://people.binf.ku.dk/~hanne/b2evolution/blogs/index.php/2009/09/01/neatx-is-
the-new-black

essentially this line:
export LD_LIBRARY_PATH="/path/where/you/put/the/libs/"
goes into /usr/local/lib/neatx/nxnode-wrapper and
/usr/local/lib/neatx/nxserver-login-wrapper

btw: the libs I put into that directory were:
libX11.so
libX11.so.6
libX11.so.6.2
libXcompext.a
libXcompext.so
libXcompext.so.3
libXcompext.so.3.4.0
libXcompshad.a
libXcompshad.so
libXcompshad.so.3
libXcompshad.so.3.4.0
libXcomp.so
libXcomp.so.3
libXcomp.so.3.4.0
libXext.so
libXext.so.6
libXext.so.6.4
libXrender.so
libXrender.so.1
libXrender.so.1.2.2

Especially the lack of documentation within neatx as to which sources you need 
to get
from nomachine and then build and which libraries/binaries to extract made this 
a
non-trivial task for me.

#45 solved it for me on archlinux

Original comment by [email protected] on 5 Jul 2010 at 5:58

[GoogleCodeExporter]

An alternative solution is to write a simply script and point nxagent-path 
(variable inside of neatx.conf) to your script instead of the executable. I did 
this because there were some issues setting LD_LIBRARY_PATH in the wrapper

#!/bin/bash
export LD_LIBRARY_PATH="/usr/NX/lib"

exec /usr/NX/bin/nxagent "$@"
