Re: Testers Wanted: PyHoca-GUI for Windows 0.5.0.3-20150124

I observed the following:

If I configure PyHoca-GUI to use my password-protected key file
(header below), I get the error:
not a valid EC private key file!

If I configure PyHoca-GUI to "Discover SSH keys or use SSH agent for
X2GO authentication", and then launch Pageant and load my
PuTTY-formatted private key into Pageant, I get the error you got:
An unknown error occurred during authentication

Did you do the latter?

Note that I can connect to this server using password authentication.

Testers Wanted: PyHoca-GUI for Windows 0.5.0.3-20150124

Hello X2Go users,

It's been a long time since a stable version of PyHoca-GUI for Windows
was released.
(.0.4.0.8 was released on 2013-08-27)

I have started maintaining PyHoca-GUI for Windows. I managed to build
0.5.0.3 successfully.
I am making a build available today, so its version string is 0.5.0.3-20150124
http://code.x2go.org/releases/binary-win32/pyhoca-gui/releases/0.5.0.3-20150124/

Please test and provide feedback (via either replies or by reporting
bugs). Since it is has been so long, I am concerned that there might
be  Windows-specific regressions.

If no new "grave" or "critical" bugs are reported within a few days, I
will announce this as a release on x2go-announcements & I will update
the link on the X2Go home page.

If anyone would like to contribute or inspect the source, this build
was built from the 0.5.0.3-mswin branch.
http://code.x2go.org/gitweb?p=pyhoca-gui.git;a=shortlog;h=refs/heads/0.5.0.3-mswin

Segfault of QDialog in a PyQt application

Package: x2go

Version: 4.0.3.0 

Qt 4.8.6

 

When we run our PyQt application on our Debian Wheezy computer with an ssh –X connection it work fine

But when we use X2Go to access the computer and we run our application we’ve got a segmentation fault at the first QDialog opening. (when we run QDialog.exec_).

We recently update the X2Go version and before that update it was working fine.

We found at least one post that describe the same problem in January 2014 on your bug report site :

X2Go Bug report logs - #410

Segfault of _X11TransWritev in libNX_X11.so.6 with libQtGui

 

Like suggested in this report  if we run a simple application to test an opening of a dialog box it work fine with X2Go

 

From your experience of this bugs is there any way to solve this problem ?

 

Sincerely,

Desktop sharing like "screen -x" with X2GO?

Hello,

I tried asking this question on IRC but I must have chosen a time when everyone was busy or away. I'm not subscribed to the list so I appreciate a CC to my address for replies.

Is it possible with X2GO to connect to the same session from two different machines at the same time? Like you would do using "screen -x" for a terminal.

- The two machines log in via SSH to the X2GO server using the same user
- If a session is started from the first machine, it seems to me (hopefully I'm wrong!) that from the second machine I can only suspend that session (kicking out the first machine) and then resume it. I would like both machines to be connected at the same time

This is actually for two different users collaborating on the same screen, but they access the same user on the server so I don't think it matters; in any case I don't want user B to disconnect user A when they connect, and they need to be on the same session because they are working together on the same application.

Any help is greatly appreciated, thanks in advance.

x2go login error

My x2go server is my desktop at work and there is a .bashrc that launches keychain and loads my ~/.ssh/id_dsa into the session environment.

the terminal gets the following output before the prompt:

 * keychain 2.7.1 ~ http://www.funtoo.org
 * Found existing ssh-agent: 1829
 * Known ssh key: /home/rhall/.ssh/id_dsa

Then you get a bash prompt.

This output becomes the text of the error message when I try to connect to this same box via x2go-client.

The relevant lines in .bashrc are:

/usr/bin/keychain ~/.ssh/id_dsa
source ~/.keychain/rhall-sh

Failed to restore all required visuals, can't resume NX session on this display

Hi,

I heard that this bug should be fixed, but I still have it:

When resuming a session on a Linux machine that was created on Windows.

X2go server version:
4.0.1.18-0x2go1+git20141006.949+wheezy.main.1

X2go windows client version:
4.0.3.1-20141214

X2go Linux client version:

V. 4.0.3.1



Is there an error log that could give some information what is going wrong here?

Thanks,

Markus

Stuck in Fullscreen

Hi,

I use X2go from a Windows 7 machine and have noticed that now one session with one user always goes into full screen mode, although I don't want this. Is there a way to set this anywhere in the client config?

CTRL ALT F does not work and has no discernable function in this session.

Thanks,

Markus

connection failed DBI

I have a new x2go server setup on a Red Hat 6.3 system.  When I try to
connect to it I get the following:
Connection failed DBI
connect('dbname=/home/x2gouser/x2go_sessions','',...) failed: unable to
open database file at /usr/lib64/x2go/x2gosqlitewrapper.pl line 89
[limit users] at /usr/lib64/x2go/x2gosqlitewrapper.pl line 89. 

On the server, I tried to do a x2godbadmin --createdb and I got:
Can not find user (x2gouser)

So, I added user x2gouser and redid the x2godbadmin.
Now I get the error above.

I normally run Debian machines and have never had to do the adduser or
x2godbadmin that I can remember.

What do I need to do to get the x2go server working?

Display stopped working??

I’m running X2go on a Mac, and connecting to a VM running Fedora 20. It’s been running for a couple of weeks now without any problems.

This morning, I typed in the command “gvim”  and got a message that the display wasn’t working – it opened vi in the terminal window instead of popping up a new window.
The display is working fine…

I tried the command ‘xterm’ and got this:

[ncohen <at> ncohen-dev-fedora bin]$ xterm
No protocol specified
xterm: Xt error: Can't open display: :51

It was working fine 2 minutes ago – system has not been updated or rebooted. SELinux is installed and in permissive mode.

I’m not sure if this is something to do with X2go or with Fedora – I’ve never seen it before. Anyone have any idea what might be going on here? Existing windows on my screen seem to be working fine, but I can’t open any new windows… I’m confused – any help would be most appreciated…

Thanks in advance,

x2gomountdirs only after 2 minutes

Hi all,

On some computers I login with a user and in the syslog I get:

Jan 15 16:06:57 lin-cad-dev-ubuntu /usr/bin/x2gomountdirs[11380]: WARNING: mounting of /cygdrive/C/Users/xxxx/X2GO~1/S-1A99~1/spool failed

As a result, not only is the session slower with logging in but also the logout can take 20-30 seconds.

In the file: /tmp/.x2go-xxxx/C-xxxx-51-1421334287_stDMATE_dp32/sshfs-mounts.log (END)
I see:
read: Connection reset by peer

At first I was thinking the mount is not working but it does mount, after 2 minutes:
Jan 15 16:14:25 lin-cad-dev-ubuntu /usr/bin/x2gomountdirs[14553]: WARNING: mounting of /cygdrive/C/Users/Geert/X2GO~1/S-102D~1/spool failed

Logging in on a different computer with the same user = no problem. (both x2go clients are v4.0.3.1 on windows 8.1)

Is this anything I can (easily) resolve?


Regards,
Kristof.
