Bug#1265: Remote proxy closed session while negotiating the connection.
by nanook＠eskimo.com 30 Jan '24

30 Jan '24

Package: nxproxy (guessing) Version: xenial 2:3.5.0.33-0~710~ubuntu16.04.1 amd64 It appears to be connecting then aborts with a pop-up: The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server. The main window very briefly displays this message: Loop: PANIC! Failure negotiating the session in stage '7'. Error: Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie. Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Tue Feb 27 02:54;49 2018'. Session: Session terminated at 'Tue Feb 27 02:54;49 2018'. The server is Zircon 12.2 and the Client is Ubuntu 17.10. This was working yesterday, I installed nightly builds and it did not work at all, then purged everything and went back to daily and now I get this.

Package: x2goagent Version: 3.5.0.16-0 There seem to be gtk related issues with GTK in Wheezy. You'll get an error similar to Gdk-WARNING **: The program 'gnome-control-center' received an X Window System error. This probably reflects a bug in the program. The error was 'BadLength (poly request too large or internal Xlib length erro'.

Bug#554: Disable local screensaver when x2go session is in fullscreen mode
by Reinhard Tartler 30 Jan '24

30 Jan '24

Package: nxproxy Severity: serious I noticed that the when nxproxy is in fullscreen mode, it (by design) captures all keyboard strokes. This is in general great because this way all keyboard shortcuts on the remote work. However, the local screen saver might still kick in and require a password. Because the nxproxy captures all input, a less carefull user might enter his local password into the current application that is running in the x2go session. When the remote application happens to be a chat application, entering your password might have serious security implications. I think a fullscreen nxproxy is a good reason to inhibit the local screensaver. -- regards, Reinhard

Bug#1609: Location of Dollar Sign
by Stefan Baur 30 Jan '24

30 Jan '24

Hi Bart, is that dollar sign located at the beginning, in the middle, or at the end of the user name? man 8 useradd states (emphasis mine): "It is usually recommended to only use usernames that begin with a lower case letter or an underscore, followed by lower case letters, digits, underscores, or dashes. They can *end* with a dollar sign. In regular expression terms: [a-z_][a-z0-9_-]*[$]?"

Bug#1125: Remote printing not working in Debian Jessie
by JR 30 Jan '24

30 Jan '24

Package: cups-x2go Version: 3.0.1.3-0x2go1+git20161129.135+8.main.1 I tried printing on the local PC from the x2goclient without success. x2goclient gives no message. I installed x2goserver-printing, cups, cups-x2go and I have installed x2go virtual printer. This happens to me only in Q4OS 1.18-Orion (Debian Jessie based). In Q4OS 2.2-Scorpion (Debian Stretch based) it works perfectly. For more details, please give a look at: http://www.q4os.org/forum/viewtopic.php?id=1261 Thank you and congratulations for your work.

Bug#1490: x2goagent crashes when pasting clipboard contents
by Tristan Miller 30 Jan '24

30 Jan '24

Package: x2goserver-x2goagent Version: 4.1.0.4 Severity: grave I am running two openSUSE Tumbleweed machines, both with x2goserver 4.1.0.4 (from Git commit gaef470fe) and x2goclient 4.1.2.2, and often use X2Go in single application mode to connect between them. Following a Tumbleweed update on the client machine (from 20200708 to 20200724), the X2Go connection now disconnects whenever I copy text into the clipboard on the local machine and then paste it into the remote machine. The following error message appears in the system log of the remote machine: 2020-07-28T11:16:12.479151+02:00 butterfield systemd-coredump[18451]: Process 17960 (x2goagent) of user 1000 dumped core.#012#012Stack trace of thread 17960:#012#0 0x00007fdd0c65c4b1 raise (libc.so.6 + 0x3c4b1)#012#1 0x00007fdd0c645539 abort (libc.so.6 + 0x25539)#012#2 0x00007fdd0c69f827 __libc_message (libc.so.6 + 0x7f827)#012#3 0x00007fdd0c72f4f2 __fortify_fail (libc.so.6 + 0x10f4f2)#012#4 0x00007fdd0c72f4c2 __stack_chk_fail (libc.so.6 + 0x10f4c2)#012#5 0x000055ae7290e691 nxagentCollectPropertyEvent (nxagent + 0xb9691)#012#6 0x000055ae728f54b3 nxagentDispatchEvents (nxagent + 0xa04b3)#012#7 0x000055ae728f9b3a nxagentWakeupHandler (nxagent + 0xa4b3a)#012#8 0x000055ae728ddde3 WaitForSomething (nxagent + 0x88de3)#012#9 0x000055ae728b747a Dispatch (nxagent + 0x6247a)#012#10 0x000055ae728965f6 main (nxagent + 0x415f6)#012#11 0x00007fdd0c646cca __libc_start_main (libc.so.6 + 0x26cca)#012#12 0x000055ae728989ea _start (nxagent + 0x439ea) The Tumbleweed update included some changes to X11/KDE packages that broke at least one other application (most notably emacsclient) so perhaps this is also the case here. (Though according to the openSUSE bug triagers, the breakage is the other application's fault.) I am running KDE on the local machine; I haven't tested if the problem is reproducible with a different desktop environment. Detailed steps to reproduce: 1. On the local machine, configure an X2Go connection to a remote machine to launch a single application such as xfce4-terminal or konsole, and then launch that connection. 2. On the local machine, use the mouse to select some text in a locally running application, which will copy it to one of the clipboards. (Alternatively, copy it to the other clipboard with Ctrl+C or Ctrl+Ins.) 3. On the local machine, switch to the remote window and paste the contents of the clipboard by middle-clicking. (Alternatively, paste the other clipboard with Ctrl+V or Shift+Ins.) At this point the X2Go session will disconnect and the above-noted error message gets written to the remote machine's system log.
