Bug#323: x2go server refuses client with 'Error: Wrong version or invalid session authentication cookie.'
by harry mangalam 15 Jan '24

15 Jan '24

Package: x2goserver Version: 4.0.1 x86_64, CentOS 6.4, kernel 2.6.32-358.18.1.el6.centos.plus.x86_64 (also x2go version 4.0.1.6 (self-compiled) on the same platform) Problem: After a server OS lockup and reboot, the previously working x2goserver would not allow client connections from Mac, Linux, Windows. After re-installing x2gserver (x2goserver-4.0.1.6-1.1.x86_64) and x2goagent (x2goagent-3.5.0.20-4.1.x86_64), it refused to connect with the client-side message: === Session: Starting session at 'Fri Oct 11 18:11:36 2013'. Info: Connecting to remote host 'localhost:31030'. Info: Connection to remote proxy 'localhost:31030' established. Error: The remote NX proxy closed the connection. Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Fri Oct 11 18:11:37 2013'. Session: Session terminated at 'Fri Oct 11 18:11:37 2013'. === (dont know if this is complete since the popup only lasts 2s.) This error has been cited multiple times in various fora and lists, but no one seems to have been able to solve it. I can passwordlessly ssh to both servers just fine from other Linux clients. If I don't use the ssh keys, I can enter my password and the result is the same. The server seems to be initializing the session since if I try to log in multiple times, there are new sessions listed, but I'm not allowed to connect to them. I can only terminate or suspend them. Terminating them does appear to work since they are not listed on following sessions if I do. The problem does seem to be related to authentication or authorization; we use ldap-based auth on the server and it's working fine otherwise, except for x2go.

Bug#1010: Slow repaint on window move (single application)
by Sebastian Loncar 15 Jan '24

15 Jan '24

Package: x2goclient Version: 4.0.5.1 When connecting in single application mode, and you move the window by dragging the title bar, the app freezes. If you have two windows open, you see on the windows behind the top window a very slow repaint (up to a minute, depends on how long you moved the window before). After repaint, the app works again. This issue does not happen, if you maximize/restore the window or move them to another monitor via keyboard shortcut. Please see the attachment. I moved the xterm from the middle to the right, i took the screenshot while the very long repaint process. With this bug, the single app mode is nearly useless. I'm using XFCE4 on Arch Linux.

Bug#684: select_session offers offline servers to X2Go Client
by Mike Gabriel 15 Jan '24

15 Jan '24

Package: python-x2gobroker Severity: important Version: 0.0.3.0-preview The X2Go Session Broker should be able to detect offline X2Go Servers. It should not offer session via the select_session() method to X2Go Client, if a server is offline.

Bug#954: SFTP server fails to read dirs containing files with umlauts
by Mike Gabriel 15 Jan '24

15 Jan '24

Package: python-x2go Version: 0.5.0.4 Severity: important I just discovered that the folder sharing code (integrated SFTP server) of Python X2Go chokes on directories contaning file names with umlauts. I will take a look into this soon...

Bug#324: Enable TCP socket in Pulseaudio daemon before starting up session sound
by Mike Gabriel 15 Jan '24

15 Jan '24

Package: python-x2go Severity: wishlist Enable TCP socket in PulseAudio before starting a session (that requests pulse support). See below.

I think of some kind > of script, which will be executed before pyhoca ... I got it: pacmd load-module module-native-protocol-tcp listen=0.0.0.0 before the start of pyhoca-cli let the running pulseaudio deamon open it's port. Or let pulseaudio open the port by default by adding the above line to /etc/pulse/default.pa ... Perhaps it's possible to let pyhoca, or python-x2go respectively, open the port like x2goclient does ... but for me the above solution is enough ...

Bug#809: custom items applications= field in sessions file crashes PyHoca-CLI/GUI
by Mike Gabriel 08 Jan '24

08 Jan '24

Package: python-x2go Version: 0.5.0.4 Severity: minor X2Go Client obviously is able to add extra/custom items to the applications= field in a session profile item. We observed one case where pyhoca-gui crashed when encountering this line in the sessions file: applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL, /usr/bin/Virtualbox %U, /usr/bin, /usr/bin/Virtualbox, Virtualbox, Virtualbox %U (which looks broken anyway, but PyHoca-GUI should not crash on it).
