Porting Windows X2goclient to Qt5?
by Orion Poplawski 06 May '23

06 May '23

Is any work being do to port the Windows x2goclient code to Qt5? The issue I'm running into is that the HWND type returned by wapiFindWindow() is not compatible with the long type - at least when compiling for 64-bit. I'm also curious that you need to shift to a Windows API call - should we be able to do everything in Qt? If I shift to 32-bit compiles I get: ../src/wapi.cpp: In function 'void wapiSetWindowIcon(HWND, const QPixmap&)': ../src/wapi.cpp:224:88: error: 'class QPixmap' has no member named 'toWinHICON' 224 | largeIcon=icon.scaled(iconx,icony, Qt::IgnoreAspectRatio,Qt::SmoothTransformation).toWinHICON (); | ^~~~~~~~~~ ../src/wapi.cpp:225:90: error: 'class QPixmap' has no member named 'toWinHICON' 225 | smallIcon=icon.scaled(smallx,smally, Qt::IgnoreAspectRatio,Qt::SmoothTransformation).toWinHICON (); | ^~~~~~~~~~ Now, the only call to wapiSetWindowIcon() is commented out, so I just commented out that code for now. Looks like the current function to use is QImage::toHICON(). -- Orion Poplawski IT Systems Manager 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

Upcoming X2Go and orca e.V. sponsorship drive - starting tomorrow, 2023-04-04
by Stefan Baur 03 Apr '23

03 Apr '23

Dear $ALL, As you might know, a few years ago, at "X2Go: The Gathering 2017", several key members of X2Go as well as members from other Remote Desktop-/Remote Application projects joined together to form the Open Remote Computing Association - orca e.V. - a registered association under Germanys Civil Code and also registered as a charitable organization, similar to a 501(c)(3) organization in the US. In June 2022, we joined betterplace.org for easier handling of donations. They offer PayPal, SEPA Direct Debit, Credit Card, giropay/paydirekt and Wire transfer. And they also handle issuing donation receipts for us. (Note that while donations towards orca/X2Go are tax-deductible for German tax subjects, this may vary in other jurisdictions.) This is to let you know that the next sponsorship drive starts Tuesday, 2023-04-04, 09:00 CEST (that's tomorrow!) and ends Thursday, 2023-04-06, 23:59 CEST. It is sponsored by the Commercial and Savings Bank Ulm, where orca's bank account resides, and they are going to distribute 10 000 EUR among all charitable organizations registered with them via betterplace.org that receive donations in the timeframe above. So it's not a 1:1 matching of each donation, but the org with the biggest amount of donations gets the biggest piece of the cake, so to speak. If you can, please visit the donation sites below on one or more of the dates mentioned and send a few €€€ our way. (But don't feel bad if you can't. Times are rough. We get that.) We'd prefer if you use the German-language donation forms because with these, we know for sure that the donation counts towards the bank's pledge. However, if you're afraid of hitting the wrong button in a German-language form, feel free to use the link that points to the English version. To donate towards X2Go: German: <https://www.wirwunder.de/projects/111056?wirwunder=235> English: <https://www.betterplace.org/en/projects/111056?wirwunder=235> Note that X2Go currently has a specific need (with a second one probably popping up soon). To donate specifically towards that need, please see the links below: English-language donation form for travel/lodging/supplies costs @ LinuxDays Chemnitz 2023: <https://www.betterplace.org/en/donate/platform/projects/111056?need_id=4715…> German-language donation form for travel/lodging/supplies costs @ LinuxDays Chemnitz 2023: <https://www.betterplace.org/de/donate/platform/projects/111056?need_id=4715…> To donate towards orca e.V., our umbrella org: German: <https://www.wirwunder.de/projects/111057?wirwunder=235> English: <https://www.betterplace.org/en/projects/111057?wirwunder=235> Kind Regards, and Thanks in Advance, Stefan Baur X2Go's Community Manager -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243

Bug#1599: Cleanup sessions on reboot
by Ulrich Sibiller 20 Mar '23

20 Mar '23

Package: x2goserver Version: 4.1.0.3 My server was rebooted during the weekend and x2golistsessions still showed a session, which of course not valid anymore. But x2goclient failed to open a connection to that server, all it reported was "session <old_sessionid> terminated". After running x2goterminatesession everything worked normally again. So I propose to cleanup the list of running sessions during bootup to prevent such weird problems from happening.

On Monday, 2023-03-20 (tomorrow!), all single (non-recurring) donations up to an amount of 200 Euro will receive 20% on top directly from betterplace.org. Donations above 200 Euro will receive 40 Euro on top from betterplace.org. The donation pool is limited to 15 000 EUR and will be used up on a first-come, first-served basis. So please try to donate early in the day. The second sponsorship drive starts Tuesday, 2023-04-04, 09:00 CEST and ends Thursday, 2023-04-06, 23:59 CEST.

X2Go Booth at Chemnitzer LinuxTage 2023 - This Weekend!
by Stefan Baur 10 Mar '23

10 Mar '23

Hi everyone! LinuxDays Chemnitz are taking place as a real-life event this Sat/Sun, and we'd love to see you there! We have secured both a booth for X2Go, as well as a handful of volunteers to staff it. If you want to support X2Go and our volunteers, you can chip in and help cover their costs for travel/lodging/supplies: <https://www.betterplace.org/en/donate/platform/projects/111056?need_id=4715…> - roughly 700 Euros should cover everything that's needed. Kind Regards, Stefan Baur X2Go's Event Planner -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243

Bug#1597: Possible security vulnerability: x2goclient crashes calling ssh-keygen due to unsanitized arguments
by Peter O'Regan 31 Jan '23

31 Jan '23

Package: x2goclient Version: 4.1.2.2-2020.02.13 x2goclient assumes the path to its application data directory does not have any spaces or single-quotes, but these are legal path directories for users on Windows systems. As a result, if the path to the x2go directory contains spaces or apostrophes (C:/Users/O'Regan, for instance), the call will fail. I have experienced this error and can reproduce the failure behavior by calling ssh-keygen from the terminal. The fix, I think, is to add double quotes to open and close the "private_key_file" string sent to ssh-keygen on onmainwindow.cpp, line 11353, or to apply a dedicated sanitization function. Testing in the terminal: ssh-keygen -f C:\Users\O'Regan\.x2go\etc\mykeyfile will fail. ssh-keygen -f "C:\Users\O'Regan\.x2go\etc\mykeyfile" will succeed. There may be other places/program calls that also need sanitizing. This is also potentially security issue since it lets the program caller influence what arguments are sent to generate an SSH key by altering the "HOME" environment variable queried by qt in line 185 from QDir::homePath(). (I'm not sure how easy it is to change this or related environment variables mid-session, but I imagine it might be possible). The path appears as the final argument to ssh-keygen, so it will also overrule the preceding arguments. For instance, I could reduce the bit count for the key or key type to make the credential easier to brute-force. I am using Windows 11. Thank you, Peter

Bug#1596: Windows 11 file sharing not working
by Krzysztof Kazanowicz 26 Jan '23

26 Jan '23

Package: x2goclient Version: 4.1.2.2 (Qt - 4.8.6) On Windows 11, when trying to mount a shared folder to remote Linux desktop, a cmd.exe window appears with error: /cygdrive/C/Users/dkopa/.x2go/etc/sshd_config line 3: Deprecated option UsePrivilegeSeparation and sharing doesn't work at all. On Windows 10 the problem was not present. This is a severe bug IMO as Windows 11 users can't share files.
