Re: X2Go client won't open desktop window on Mac OS X 10.10 Yosemite

Hi Ricardo,

I'm sorry: I did read the posts but I wasn't  sure Mike's comment actually applied to my case.
Do you or anybody else have any idea of when 4.0.3.0 is coming out?
Until it comes out, x2go is simply out of reach... :(

Client Wish List


      I use X2Go for remote administration and I originate on several different
platforms, most often Ubuntu 14.04 LTS, but also from MacOS 10.7.5 and from
Windows XP.  I also use X2Go to allow my customers remote desktop access to our 
shell servers.

      The X2Go client differs in behavior from other NX type clients in that
on systems with virtual desktops or workspaces, they keyboard sequence used
to switch workspaces, control+arrow key in the case of MacOS or 
control+alt+arrow key in the case of Ubuntu, do not work within the client,
so when I have the client full-screened, I can't switch workspaces except by 
first minimizing the client.  With OpenNX, NoMachine Player, or Remmina, I can
use the keyboard short-cuts to switch work spaces without minimizing the client
and that is much more convenient.

      Then on Mac there are further problems.  On MacOS 10.7.5, without XQuarts,
X2Go Client is completely unusable.  Keyboard translations are severely messed
up and it is unstable and usually dies or locks up within fifteen seconds.

      With XQuartz installed, behavior is much better, keyboard translation is
correct with one exception, the state of CAPS LOCK is inverted, that is, when
CAPS LOCK is on, I get upper and lower case characters, when it is off, I get
UPPER CASE only.  It's a minor nusiance and most notable when switching between 
X2Go client and other windows where I have to keep toggling the CAPS LOCK.

      Another behaviorial issue with MacOS is that it will only do full screen 
if I enable the X-server root window, however this breaks many things MacOS,
and so it is essentially not usable in full screen.  I do not have to do this
with other NX clients, they all go full screen without using the root window
and would very much desire this behavior also with X2Go client.

      On MacOS, sound does not work.  It works on Windows and Linux fine, but
not MacOS 10.7.5.  It doesn't produce any errors, but doesn't produce any sound
either.  There are no choices for audio subsystems so nothing to attempt to 
tweak.

      This isn't a bitch list, just a wish list.  I really appreciate the work
you folks have put into X2Go, aesthetically, I find it far superior to
NoMachine, it also connects far more reliably, and working sound is nice.

      I've got the server end working on Centos 6, Centos 7, Fedora 20, 
Scientific Linux 6, Scientific Linux 7, OpenSuse, Mint, Ubuntu, and until very 
recently Debian Wheezy.  I've also got freenx-server working on all of these
except Debian.  For those of you who have experienced problems with the newer
distributions move to compositing window managers that don't work with X2Go,
check out mate-desktop.org.  Mate is a fork of gnome2 that works perfectly with
X2Go and all of the above mentioned Linux distros.

X2Go Server Weirdness

     I have X2Go installed on Debian Wheezy, this is on an Intel I7-2600
based system.  Until recently it was working but now when I try to
connect with X2Go Client I get:

Connection failed "has_agent_state_file" is not exported by the
X2Go::Server::Agent module Can't continue after import errors at
/usr/bin/x2golistsessions line 28 BEGIN failed--compilation aborted at
/usr/bin/x2golistsessions line 28.

     I have removed and re-installed all X2Go software and still get this
same error.  I've rebooted the machine, no change.

     I've Googled for this error and find absolutely no matches.  The
machine seems to be otherwise running okay so I'm at a complete loss.

error in the install wiki

I’ve noticed that the x2go installation wiki has a small error… on the page here that discusses the installation for Ubuntu 14.04:

 

http://wiki.x2go.org/doku.php/doc:installation:x2goserver

 

It says to install “python-software-common”  but the correct package name is “software-properties-common” …

 

Can someone with edit access to the wiki make this trivial change?

problem with logging in and ssh banners

Hi there,
I have just installed the x2go EPEL packages on a SL 6.5 machine. It 
mostly works except that when I have a ssh banner the x2go client 
complains that a connection error occurred and displays the ssh banner. 
If I disable the banner it works just fine. I would very much like to 
keep the banner. Is this a known issue, are there any work-arounds?

I have installed the following EPEL packages
x2goagent-3.5.0.27-1.el6.x86_64
x2goserver-4.0.1.15-2.el6.x86_64
x2goserver-xsession-4.0.1.15-2.el6.x86_64

and client packages (also on SL 6.5):
x2goclient-4.0.1.4-1.el6.x86_64

I use GSSAPI for logging in without a password.

Cheers
magnus

PS: so far I am well impressed with x2go. I hope to use it to replace 
our ageing freenx service.

X2Go Server / X2Go Client with openSSH 6.7 (Debian jessie et al.)

Hi all,

openSSH 6.7 has just entered Debian unstable and will be in Debian  
jessie soon. It will probably land in other distributions rather  
sooner than later.

As the openSSH developers have--by default--disabled several kex  
algorithm in the latest openSSH 6.7 release, X2Go Client on older  
systems (Debian wheezy, Ubuntu 14.04, etc.) will fail connecting to  
those machines.

""" (This probably is the error message X2Go Client shows on your screen...)

X2Go Client reports: kex error : did not find one of algos  
diffie-hellman-group1-sha1 in list 

curve25519-sha256@...,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1
for kex  
algos

"""

The issue can be addressed in two ways...

OPTION 1:
---------
If you only have control of the client, you may get the issue resolved  
by backporting a libssh 0.6.3 version. Consult your distribution's  
build tools to make this happen.

I will checkout what we as X2Go upstream can provide for you in our  
package repositories without breaking other parts of your system  
(older applications using libssh << 0.6.0 are very likely to break  
with that newer libssh).

OPTION 2:
---------
If you have control of the server, then you may want to re-enable the  
mode-insecure, older, by-default-disabled algos. From the sshd_config  
man page in openSSH 6.7:

"""
      KexAlgorithms
              Specifies the available KEX (Key Exchange) algorithms.  Multiple
              algorithms must be comma-separated.  The supported  
algorithms are:

                    curve25519-sha256@...
                    diffie-hellman-group1-sha1
                    diffie-hellman-group14-sha1
                    diffie-hellman-group-exchange-sha1
                    diffie-hellman-group-exchange-sha256
                    ecdh-sha2-nistp256
                    ecdh-sha2-nistp384
                    ecdh-sha2-nistp521

              The default is:

                    curve25519-sha256@...,
                    ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,
                    diffie-hellman-group-exchange-sha256,
                    diffie-hellman-group14-sha1
"""

What you probably have to add to the KexAlgorithms parameter in  
/etc/ssh/sshd_config are these additional algos:  
diffie-hellman-group1-sha1 and diffie-hellman-group-exchange-sha1.

"""
KexAlgorithms  
curve25519-sha256@...,diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521
"""

If you use the KexAlgorithms option in sshd_config, make sure that you:

   o also add all the default algos
   o restart openSSH server on your server and try a second login
     while you are still logged in with another session (in case you
     broker something by editing sshd_config)

Mike

x2go broker server integration with ballast

Greetings,
   I'm looking for a load balancing solution for X2Go, and I've seen ballast turned up in several searches.  It looks promising, but I was wondering if anyone has worked with it specifically in regards to X2Go, and even better, the Broker Server?

   I've tried using the Cluster Services developed by the X2Go team, but it seems to have major issues with root-squashed NFS mounted home directories, so it's somewhat of a no go for me.  Hence, my quest for open source alternatives.

Thanks in advance for your consideration and suggestions!
