x2gokdrive build question
by Orion Poplawski 17 Jul '23

17 Jul '23

I'm working on packaging x2gokdrive for Fedora and I'm seeing the following in the configure log for the xorg x11 server: configure: WARNING: *********************************************** Neither HAL nor udev backend will be enabled. Input device hotplugging will not be available! *********************************************** Is this of any concern for kdrive? I do see that there is an explicit: --disable-config-hal \ --disable-config-udev \ so probably not. But it *seems* like input device hotplugging might be useful just judging by the name. But perhaps not since this is on the server end of things?

Bug#1469: X2Go Client connection issue (Socket error)
by Melroy van den Berg 29 Jun '23

29 Jun '23

Package: x2goclient Version: 4.1.2.2 I often get an error message when I try to connect to my Debian buster docker image, running x2goserver and XFCE, via the X2Go Client on my host machine. It will give the following error message (when using the --debug flag on the x2goclient): x2go-DEBUG-../src/sshmasterconnection.cpp:2071> "ssh_channel_open_session failed": "Socket error: No such file or directory" x2go-DEBUG-../src/sshprocess.cpp:478> I/O error: "ssh_channel_open_session failed."" - Socket error: No such file or directory" (0). I created a detailed video, I posted it on YouTube, please take a look at the video: https://youtu.be/LAlLtBNTIUo Logging details, reproducibility and more is explained in the video itself. You'll notice that I can sometimes connect to the XFCE session and sometimes I can't. Although connecting via the ssh cli command is always working without any issues. Meaning there is really some kind of bug in the X2Go Client. I'm afraid. Again, I really hope somebody could help me in finding the root-cause and fixing the issue. Since I really love X2Go. And I would like to use this tool in production. I'm also a software developer so maybe I can help debugging the problem. Similar (same) bug is reported in the past (from 2019): https://lists.x2go.org/pipermail/x2go-user/2019-March/005512.html All the details regarding this Docker image and setup can be found in this git repo: https://gitlab.melroy.org/melroy/xfcevdi See attachments for additional debug logs of the client itself. One when successful and one during the error. Thanks in advance! Kind regards, Melroy van den Berg Ps. You can contact me by mail of course. But I can understand that debugging this issue would be preferable be done via VoIP for example.

Two upcoming real-life events (this and next weekend)/Call for Donations
by Stefan Baur 28 Jun '23

28 Jun '23

Dear $ALL, X2Go will be present at the TUEBIX Linuxday <https://www.tuebix.org/> in Tübingen, Germany, this Saturday, July 1st, and also at the Hack4Glarus Hackathon <https://hack4glarus.ch/> in Diesbach (Glarus), Switzerland, from Friday, July 7th to Sunday, July 9th. At TUEBIX, we will demo X2Go-KDrive, at Hack4Glarus, we will take a closer look at how well (or how bad) X2Go works in an IPv6 network. If you're planning to attend and/or are in the area, feel free to stop by and say hi! We are trying to cover the costs for our three volunteers/orca e.V. members (Mihai, Juri, and last but not least me) via orca e.V., the registered association that X2Go belongs to, but for that, we will need your help in the form of donations*. You can find our donation pages here: X2Go (English): <https://www.betterplace.org/en/projects/111056?wirwunder=235> X2Go (German): <https://www.betterplace.org/de/projects/111056?wirwunder=235> orca e.V.

(German): <https://www.betterplace.org/de/projects/111057?wirwunder=235> It would be really cool if you could send some $$$/€€€/£££/¥¥¥ our way, so we can keep advocating for X2Go and free remote desktop/remote application projects in general. We can accept donations via PayPal, Credit Card, Direct Debit, giropay/paydirect and wire transfer. Best of all, donations towards X2Go and orca are usually tax deductible for German tax subjects.

X2Go Client Vulnerabilities
by Mark Vandenberg 25 Jun '23

25 Jun '23

Hi X2Go Dev Team, Firstly, thanks for providing such an amazing product. I'm a long time user and very grateful fan. My organisation is currently doing a security assessment of the X2Go client. They have asked me to reach out to you to determine the following: "Assuming that you do not have any alternative software clients that can be used for connectivity to the x2go server, would you be able to help to address the compliance issues raised by asking the vendor to confirm whether v4.1.2.2 actually has any vulnerabilities they are aware of and if this is still supported by them?" I think these concerns arise from the age of v4.1.2.2. Can you please answer the above? This is regarding both the X2Go client version and if an alternative client can be used. Thanks and regards, [cid:image001.png@01D9A810.27CE12A0] Mark Vandenberg Senior Solutions Architect 757 Ann Street Fortitude Valley 4006, Queensland, Australia Phone: +61 (417) 443626 Mobile: +61 (417) 443626 E-mail: mark.vandenberg(a)hitachienergy.com<mailto:mark.vandenberg@hitachienergy.com> www.hitachienergy.com<https://www.hitachienergy.com/> [cid:image002.png@01D9A810.27CE12A0]<http://www.facebook.com/hitachienergy.global> [cid:image003.png@01D9A810.27CE12A0] <http://www.instagram.com/hitachienergy> [cid:image004.png@01D9A810.27CE12A0] <http://www.twitter.com/hitachienergy> [cid:image005.png@01D9A810.27CE12A0] <https://www.youtube.com/c/hitachienergy> [cid:image006.png@01D9A810.27CE12A0] <http://www.linkedin.com/company/hitachienergy> [cid:image007.png@01D9A810.27CE12A0]<www.hitachienergy.com>
