Bug#996: x2go client issues using HTTP proxy
by Nimesh Jethwa 08 Feb '16

08 Feb '16

Package: x2goclient Version: 4.0.5.0-0 When trying to connect to a session using HTTP proxy, it fails the first time with the below message in an error dialog. "Socket error: disconnected" When connecting to the same session the second time within 30 secs, the connection goes through and I am logged into my virtual desktop. I am able to replicate this issue several times. Below is the output of the client running in debug mode (with the above scenario captured) - ========== x2go-INFO-8> "Starting connection to server: desktop.a1200.virtualorgs.net:80" x2go-DEBUG-../src/onmainwindow.cpp:2758> Starting new ssh connection to server:"desktop.a1200.virtualorgs.net":"80" krbLogin: false x2go-DEBUG-../src/sshmasterconnection.cpp:168> SshMasterConnection, host "desktop.a1200.virtualorgs.net"port 80user "superuser"useproxy trueproxyserver "desktop.a1200.virtualorgs.net"proxyport 80 x2go-DEBUG-../src/sshmasterconnection.cpp:205> Starting SSH connection without Kerberos authentication. x2go-DEBUG-../src/sshmasterconnection.cpp:209> SshMasterConnection, instance SshMasterConnection(0x10d8030) created. x2go-DEBUG-../src/sshmasterconnection.cpp:445> SshMasterConnection, instance SshMasterConnection(0x10d8030) entering thread. x2go-DEBUG-../src/sshmasterconnection.cpp:481> libssh not initialized yet.

Also, I can replicate this issue on Debian 8 - v4.0.3.1-4 and Windows 7 - v4.0.5.0. Any help here would be greatly appreciated. Thanks, Nimesh

Bug#989: pyhoca-gui fails to fall back to Gtk-2.0 notifications (pynotify)
by Ondřej Grover 04 Feb '16

04 Feb '16

Package: pyhoca-gui Version: 0.5.0.5-0x2go1+git20160128.1329+jessie.main.1 Dear maintainers, I believe commit e44e848415eff3e4dab69e990adfc447e79143f8 which introduced GTK3 notification support broke GTK2 notification support fallback. The problem was not present in 0.5.0.4 I believe the problem lies in this import construct in pyhoca/wxgui/notify.py which will fail the same way even when put alone in a file try: from gi.repository import Notify as _Notify except ImportError: import pynotify as _Notify I think the problem is that even if the GTK3 Notify module is not available, many GTK3 libraries get loaded and then the pynotify import fails with ImportError: could not import gobject (could not find _PyGObject_API object) This is the same exception I see when running pyhoca-gui. I think some more sophisticated GTK version selection mechanism is needed, one that would not start loading conflicting libraries. As a workaround for now I just removed that GTK3 import on my system. My system is Debian 8.3 Jessie with the following (possibly relevant) gtk packages installed dpkg -l | grep '^.i.*gtk[23].*' ii libavahi-ui-gtk3-0:amd64 0.6.31-5 amd64 Avahi GTK+ User interface library for GTK3 ii libcanberra-gtk3-0:amd64 0.30-2.1 amd64 GTK+ 3.0 helper for playing widget event sounds with libcanberra ii libcanberra-gtk3-module:amd64 0.30-2.1 amd64 translates GTK3 widgets signals to event sounds ii libdbusmenu-gtk3-4:amd64 12.10.2-1 amd64 library for passing menus over DBus - GTK+ version ii libgirara-gtk3-1:amd64 0.2.3-1 amd64 library for minimalistic user interfaces (shared libraries, GTK+ 3) ii libgtk2-ex-podviewer-perl 0.18-1 all Perl Gtk2 widget for displaying Plain Old Documentation (POD) ii libgtk2-ex-simple-list-perl 0.50-2 all simple interface to Gtk2's complex MVC list widget ii libgtk2-imageview-perl 0.05-2+b1 amd64 Perl bindings for the GtkImageView image viewer widget ii libgtk2-perl 2:1.2492-4 amd64 Perl interface to the 2.x series of the Gimp Toolkit library ii libgtk2.0-0:amd64 2.24.25-3 amd64 GTK+ graphical user interface library ii libgtk2.0-bin 2.24.25-3 amd64 programs for the GTK+ graphical user interface library ii libgtk2.0-common 2.24.25-3 all common files for the GTK+ graphical user interface library ii libwxgtk3.0-0:amd64 3.0.2-1+b1 amd64 wxWidgets Cross-platform C++ GUI toolkit (GTK+ runtime ii pinentry-gtk2 0.8.3-2 amd64 GTK+-2-based PIN or pass-phrase entry dialog for GnuPG ii python-gtk2 2.24.0-4 amd64 Python bindings for the GTK+ widget set ii python-wxgtk3.0 3.0.1.1+dfsg-2 amd64 Python interface to the wxWidgets Cross-platform C++ GUI toolkit Kind regards, Ondřej Grover

The following commits on x2goserver branch release/4.0.1.x are problematic because they make use of system_capture_stdout_output which is not in that branch: commit 27b0fd76c4428ca45f30eeb577b1aafb205083c9 Author: Mihai Moldovan <ionic(a)ionic.de> Date: Mon Jun 22 23:48:45 2015 +0200 x2goserver/sbin/x2gocleansessions: move up session status sync a bit, don't update session state when session has been removed from the database. commit 08ab5c8b404690062a34f353a3294677e931ff75 Author: Mihai Moldovan <ionic(a)ionic.de> Date: Sun Jun 21 22:39:05 2015 +0200 x2goserver/sbin/x2gocleansessions: re-fetch the current sessions' status before handling it. Using the "cached" value from the initial x2golistsessions run may be desynchronized with the actual current value. Avoids a race condition logging users out after they attached to a session. After fixing this, is there any ETA on a x2goserver 4.0.1.20 release? I'm seeing an issue where x2gocleansessions is continually suspending a session it appears to think is running, and am wondering if it has already been fixed. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com

X2go on EPEL6 outdated
by Reinhard Tartler 02 Feb '16

02 Feb '16

Hi, At my new employer, I've convinced our system administrators to give x2go a shot. They noticed that it is included in EPEL6 and installed it on CentOS6 workstations. This test went pretty well so far. Unfortunately, that installed version 3.5 of x2go, which as I understand it is not the best impression that we can make. We deployed it with the sqlite back end and I noticed that the cleansessions daemon appears to crash from time to time. This is very annoying in particular given that we reboot our login nodes about once to twice a year and the effects are rather unintuitive to debug. My hope is that x2go 4 is more resilient here (but I admit that I didn't check myself). In any case, I suppose it is in everyone's best interest to prefer a newer version of x2go than currently in EPEL6 (cf. https://dl.fedoraproject.org/pub/epel/6/x86_64/repoview/x2goagent.html) - because otherwise, EPEL user are not going to receive any work towards getting bugfixes. What are your thoughts on this and how would you guys advise here? Many greetings from NYC, Reinhard
