X2Go: The Spread 2023 - You (K)Drive Me Krazy! 2023-12-11 to 2023-12-10
by Stefan Baur 11 Nov '23

11 Nov '23

Dear $ALL, In exactly one month, from December 11th to December 15th, we'll have our annual X2Go meeting for users, admins and code contributors to X2Go - once again, 100% virtual/online, so it's a "The Spread" and not a "The Gathering" once more. We're hoping to see you there. We'll post a link to a virtual meeting room in due time, and expect to be streaming/recording the event to YouTube or a similar platform as well. Starting time will likely be 20:00 CET, as last year, unless a significant number of participants requests an earlier start time (say, 18:00 CET or 19:00 CET) - please let me know (off-list, see below for contact details) if you'd like to request an earlier start time. Sadly, in summer, where Covid numbers and weather conditions would have allowed for a real-life meeting, we had a scheduling conflict. And as the numbers are rising again, we cannot in good conscience host a real-life international conference - especially as some of our members have vulnerable household members or are vulnerable persons themselves. The event page (still work in progress) can be found here: <https://wiki.x2go.org/doku.php/events:x2go-spread-2023> Each evening has one, max. two time slots for a talk/presentation. At the moment, three topics are confirmed: - The usual "X2Go: State of the Union" opening speech - A report looking back at our latest stable X2Go release, which brought KDrive into the stable repository, and showing what still needs to be done Re: KDrive. - A report on how we used betterplace.org for collecting X2Go-related donations in the last 18 months, and an open discussion on how we could improve our usage of this platform. I am also hoping for a certain volunteer to commit to a fourth presentation regarding the latest changes and improvements in NX-Libs - since Arctica/NX-Libs pushed out a new release as well (on which our X2Go release is also based, obviously). This means we will have at least one more open talk slot - possibly more, if the two release reports for NX-Libs and X2Go only take 10-15 minutes each. If nobody volunteers, I might fill that remaining slot with a quick demo of how to netboot X2Go-TCE-Live via iPXE in EFI and legacy mode. But I'm really hoping for more volunteers for talks/demos/presentations - so if you would like to present something X2Go/NX-Libs/Arctica-related, please let me know (again, off-list, see below for contact details). We also have the option to prerecord your talk, in case your schedule doesn't allow for a live presentation and/or your internet connection is too flaky. It would be nice if you're available for a live Q&A round after your talk, though (via text-only chat or audio-only stream is fine). Please note that this time, the orca e.V. annual meeting will take place on the Sunday morning *before* the start of X2Go: The Spread 2023. All orca e.V. members have already received their invitation. To contact me, please do not hit "reply"/"reply to all"/"reply to list", but rather, send a *new* E-Mail to <mailto:X2Go-ML-1@baur-itcs.de>. Kind Regards, Stefan Baur -- 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

x2gokdrive freezing
by Neal Becker 31 Oct '23

31 Oct '23

I've been testing x2gokdrive on fedora 38 (client and server). It's generally working, but I just got a freeze that is not recoverable. That is, the session has gotten into a state so that when I try to reconnect, it only starts to open the display and hangs. The display is set for full screen. When reconnecting, I first will see a black window, then the window will become full size and display normally. In this stuck state, I only see a small all black window. Here is the log of attempt to reconnect: MAIN:x2gokdriveremote.c:142,remote_handle_signal() GOT SIGNAL 1 MAIN:x2gokdriveremote.c:3340,processConfigFileSetting() Using JPEG Compression MAIN:x2gokdriveremote.c:3346,processConfigFileSetting() JPEG quality 99 is requested, x2gokdrive will override it to 70 MAIN:x2gokdriveremote.c:3350,processConfigFileSetting() Image quality: 70 MAIN:x2gokdriveremote.c:3357,processConfigFileSetting() accept localhost MAIN:x2gokdriveremote.c:3367,processConfigFileSetting() listen 52837 MAIN:x2gokdriveremote.c:3389,processConfigFileSetting() CLIPBOARD MODE: both MAIN:x2gokdriveremote.c:3325,processConfigFileSetting() state file /tmp/.x2go-nbecker/C-nbecker-50-1698764366_stKstartplasma-x11_dp24/state MAIN:x2gokdriveremote.c:2142,setAgentState() Agent state RESUMING MAIN:x2gokdriveremote.c:3227,open_socket() Openning TCP socket...

Bug#1614: Initial resize to 800x600 on resume is problematic
by Orion Poplawski 16 Oct '23

16 Oct '23

Package: x2gokdriveclient Version: 0.0.0.1 When resuming a session, the KDrive client resizes the desktop to 800x600 before resizing it to the size set in the session preferences. This is problematic especially with KDE desktop sessions because the windows get moved/resized to fix the smaller desktop. Preferably the session should not get resized at all but start at the same size it was when suspended. This may be tricky though without extending the x2go session schema to record the desktop size. Next best would be to just immediately start with the session preferences size. This is seen with EL8 servers and clients. -- 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/

Could not open default font 'fixed'
by Bertram Franz 16 Oct '23

Hi, I still see https://github.com/ArcticaProject/nx-libs/issues/84 on my OpenSuse, with x2goserver-x2goagent: 3.5.99.24 (from x2goserver-x2goagent-4.1.0.7-0.0x2go1.0.git20230823.1996.heuler.x86_64 = latest nightly build). Is there anything I can do to analyze that further? Is there a workaround to get the server to run? Thanks, Bertram

x2gokdrive memory corruption
by Orion Poplawski 09 Oct '23

09 Oct '23

I'm seeing x2gokdrive abort with "malloc(): unsorted double linked list corrupted", which indicates some memory corruption. Is anyone else seeing this? Has anyone tried running x2gokdrive under valgrind? Any tips for doing that? -- 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/

Questions about x2gokdrive licensing
by Orion Poplawski 29 Sep '23

29 Sep '23

I'm trying to package x2gokdrive for Fedora, but running into some questions/issues with the licensing: 1 - There is no license file in the released tarball 2 - The debian/copyright file in the git repo states that the license is GPL-2+ except for testscripts/* at GPL-2. However, licensecheck reports: ./x2gokdrive.c: Historical Permission Notice and Disclaimer - sell variant ./x2gokdrive.h: GNU General Public License v3.0 or later ./x2gokdrivecursor.c: GNU General Public License v3.0 or later ./x2gokdriveinit.c: GNU General Public License v3.0 or later ./x2gokdrivelog.h: Historical Permission Notice and Disclaimer - sell variant ./x2gokdriveremote.c: GNU General Public License v3.0 or later ./x2gokdriveremote.h: GNU General Public License v3.0 or later ./x2gokdriveselection.c: GNU General Public License v3.0 or later ./x2gokdriveselection.h: GNU General Public License v3.0 or later 3 - This code is combined with the Xorg server code which is under the MIT license. This is quite a mess. Any chance this could be cleaned up?

loginctl 'enable-linger' causes systemd --user to respawn on boot
by Montjoy, Robert (montjoy) 28 Sep '23

28 Sep '23

Hi. At one time "loginctl enable-linger" was added to the x2gostartagent to make sure the systemd did not kill the x2go process on disconnect. This has had the probably undesired affect of having systemd --user username being executed on boot for every x2go user. At the last boot about 70 processes (one for systemd and one for pam) were spawned. This is probably not what we want. Is there a better way to handle the systemd termination issue? Should something like systemd-run --scope --user x2goagent ..... be used instead? Or can x2go cleanup this entry on termination? Maybe have x2gocleansessions do it? Note: I will probably cleanup /var/lib/systemd/linger on boot by executing rm -f /var/lib/systemd/linger/* but that it is more of a "hammer" approach than anything else. Thanks in advance. Rob

Next Events/Upcoming X2Go and orca e.V. Sponsorship Drive - Tomorrow, 2023-09-05
by Stefan Baur 04 Sep '23

04 Sep '23

Dear $ALL, X2Go will be present at LinuxDay.AT <https://www.linuxday.at/> in Dornbirn, Austria on Saturday, September 30th, and also at the IT-Kongress <https://it-kongress.com/> in Neu-Ulm, Germany, on Thursday, November 9th, 2023. At both events, we will have a booth where we will demo X2Go-KDrive, as well as the HTML5Client beta and X2Go's integration into the latest Remmina client. At LinuxDay.AT, there will also be a talk with a live demo of how you can run a small X2GoServer instance in the Google Cloud, for free, using Tor (The Onion Router) to log in. The talk at IT-Kongress will be a behind-the-scenes look regarding the customer-driven development that led to the creation of X2Go-KDrive. (Note that both talks will be in German, but our booth staff at both events is fluent in German as well as in English.) If you're planning to attend and/or are in the area, feel free to stop by and say hi! Both events are free, though IT-Kongress requires registration. We are trying to cover the costs for our two volunteers/orca e.V. members (Mihai and 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. (English): <https://www.betterplace.org/en/projects/111057?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. Note that there is a special sponsorship drive sponsored by our funding platform, betterplace.org: Non-recurring donations up to 100 Euro made on Tuesday, 2023-09-05 (starting 00:00 CEST) will receive 20% on top directly from betterplace.org. Larger donations will receive 20 Euro on top instead. This offer is only valid until a funding pool of 12.000 Euro is depleted. So the earlier you donate on this particular day, the higher the chance that your donation will receive the bonus from betterplace. Kind Regards, Stefan Baur (with his X2Go Event Planner hat on) *If times are rough for you and you can't afford to donate, don't feel bad! You can also help us by forwarding this announcement to whomever you seem fit - e.g. your local Linux user group, your social media followers, etc. If you're on Twitter, you can retweet and like the following to help: <https://twitter.com/farbenstau/status/1698651187577282841> (English) <https://twitter.com/farbenstau/status/1698651871773086181> (German) Feel free to copy the text and links of these Tweets to any social media platform that you are using. -- 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

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. Kind Regards, Stefan Baur (with his X2Go Event Planner hat on) *If times are still rough for you and you can't afford to donate, don't feel bad - but please forward this announcement to whomever you see fit - e.g. your local Linux user group, your social media followers, etc. If you're on Twitter, you can retweet and like the following to help: <https://twitter.com/farbenstau/status/1674074134333083650> (English) <https://twitter.com/farbenstau/status/1674068604076142599> (German) Feel free to copy the text and links of these Tweets to any social media platform that you are using. -- 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

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>

Bug#1604: Mint 20.3 Update fails for latest release 4.1.0.4-0~1975~ubuntu20.04.1 - kdrive requirement xserver-x2go is missing
by Brian G 31 May '23

31 May '23

Package: x2goserver Version: 4.1.0.4 The update failed for mint 20.3 as x2goserver-x2gokdrive requires xserver-x2gokdrive which is not available in mint 20.3 and not available from the x2go repository. It screwed up my system pretty good! had to do a clean install of 4.1.0.3 to get up and running again. I have been using x2go for years, love it! And also some documentation file was moved in 4.1.0.3 to a different file in 4.1.0.4 and the upgrade complains about that before even reporting the kdrive issue on an attempt to do a fresh install of 4.1.0.4.

Bug#1434: Use login shell for session
by Orion Poplawski 30 May '23

30 May '23

Package: x2goserver Version: 4.1.0.3 Tags: patch X2Go's Xsession file always starts the user's session with /bin/bash (at least on RedHat systems where SHELL is set to /bin/bash via ~/.bashrc calling /etc/bashrc). This patch attempts to determine the user's login shell and use that for launching the session. See also: https://bugzilla.redhat.com/show_bug.cgi?id=1794660 Another option might be the judicious use of the --norc option when launching x2goruncommand on followers but I'm not sure what other effects this will have or where to do that. Effects might not be to bad because I can simulate this by moving away the user's .bash_profile and .bashrc files and then the tcsh is used as expected in this case. However, while $SHELL does not get set in this case, the xfce4-session script still gets launched with bash which triggers some other errors, so this patch may be the best option. --- x2goserver-xsession/etc/Xsession | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/x2goserver-xsession/etc/Xsession b/x2goserver-xsession/etc/Xsession index 270a0b3..522f37e 100755 --- a/x2goserver-xsession/etc/Xsession +++ b/x2goserver-xsession/etc/Xsession @@ -117,6 +117,10 @@ if ! echo "*" >>"$WRITE_TEST"; then fi rm -f "$WRITE_TEST" +# Determine the users login shell and use that to launch the session +SHELL=$(getent passwd $LOGNAME | cut -d: -f7) +# Fallback +[ -z "$SHELL" ] && SHELL=/bin/bash if [ -f /etc/debian_version ] || [ -f /etc/devuan_version ]; then -- 1.8.3.1 -- Orion Poplawski Manager of NWRA Technical Systems 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/

You can view the complete changelog entry of src:x2goserver (4.1.0.4) below, and you can use the following link to view all the code changes between this and the last release of src:x2goserver. https://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff;h=1e0b9ce0155256… If you feel that the issue has not been resolved satisfyingly, feel free to reopen this bug report or submit a follow-up report with further observations described based on the new released version of src:x2goserver. Thanks a lot for contributing to X2Go!!! light+love X2Go Git Admin (on behalf of the sender of this mail) --- X2Go Component: src:x2goserver Version: 4.1.0.4-0x2go1.2 Status: RELEASE Timestamp: 1685472549 Date: Tue, 30 May 2023 20:49:09 +0200 Fixes: 1228 1357 1388 1395 1434 1537 1538 1583 Changes: x2goserver (4.1.0.4-0x2go1.2) RELEASED; urgency=medium . [ Mike Gabriel ] * New upstream version (4.1.0.4): - Fix version number in VERSION.x2goserver-desktopsharing. - x2goserver-x2goagent: Drop x2goagent.keyboard file. - x2goversion: Fix situations where ${compfile} contains a non-absolute path (e.g. it contains '../'). (Fixes: #1357). - Add X2Go KDrive support (wrapper package: x2goserver-x2gokdrive). - Add man page for x2gocleansessions. - x2goserver/man/man8/x2golistsessions_root.8: Mention --all-servers option. (Fixes: #1395). - x2goruncommand: Support GNOME-based Ubuntu sessions (via X2Go Kdrive) as provided by Ubuntu 18.04 or later. - GNOME sessions: Avoid firing up of a polkit-1 authentication dialog requesting admin credentials to register a new color map device. See GNOME bug: https://gitlab.gnome.org/GNOME/gnome-settings-daemon/issues/273 This change only gets activated for Debian for now and focuses on policykit-1 (<= 0.105). (Debian maintainers of policykit-1 are holding back newer versions for unknown reason). - Makefile: Create symlink from /etc/x2go/Xsession.options.d/ to /etc/X11/Xsession.options.d on Debian-like systems. - x2goserver/man/man8/x2gocleansessions.8: Update man page. * debian/x2goserver.postinst: + Drop duplicate sourcing of debconf includes. + Add Dutch debconf translation. Thanks to Frans Spiesschaert. + Add Russian debconf translation. Thanks to Lev Lamberov. + Add Portuguese debconf translation. Thanks to Américo Monteiro. + Update German translation. * debian/control: + Update (LONG_)DESCRIPTION of bin:pkg x2goserver-x2goagent. * Drop base64 from D (x2goserver): A bin:pkg does not exist, the bas64 executable is shipped as part of coreutils (which is an essential package and thus does not need a dependency). * debian/x2goserver.manpages: + Install x2goupdateoptionsstring.1* man pages into bin:pkg x2goserver. * x2goserver.spec: + Update (LONG_)DESCRIPTION of bin:pkg x2goserver-x2goagent. + Fix up files section for x2gokdrive (wrong pkg name). . [ Mihai Moldovan ] * New upstream version (4.1.0.4): - x2goserver/sbin/x2gocleansessions: add newline before POD block. - x2goserver-x2goagent/man/man1/x2goagent.1: add version and date. - x2goserver/Makefile: generate man pages from Perl POD. - X2Go/Utils.pm: fix missing semicolons. - X2Go/Utils.pm: add new is_int subroutine, checking if the provided value is an integer. - x2goserver/lib: new x2goisint wrapper. - x2goserver/lib/x2gois{int,true}: add newlines to (error) output. - x2goserver/lib/x2gois{int,true}: add optional warnings. - x2goserver/sbin/x2gocleansessions: rework manpage/POD. - x2goserver/lib: add new (stub) file x2goupdateoptionsstring to deal with options string manipulations. Currently only parsing into an intermediate state is supported, the script dumps that state for now. - x2goserver/lib/x2goupdateoptionsstring: add function to transform the intermediate options string representation back into a string and some code that uses this new function. - x2goserver/lib/x2go{is{int,true},updateoptionsstring}: use q{} instead of empty quotes as per some... coding standard. - x2goserver/lib/x2go{is{int,true},updateoptionsstring}: wrap print calls with filehandles in curly braces. - x2goserver/lib/x2goupdateoptionsstring: fix some "errors" reported by Perl::Critic in brutal mode. - x2goserver/lib/x2goupdateoptionsstring: add functionality for options removal. - x2goserver/lib/x2goupdateoptionsstring: update documentation to include the notion of the +key[=value] syntax, which makes sense to use if key starts with a dash and would be ambiguously interpreted as a removal. - x2goserver/lib/x2goupdateoptionsstring: refactor remove_option subprocedure into a more general transform_intermediate one and add code for the modification/addition case. - x2goserver/lib/x2goupdateoptionsstring: ignore some very noisy Perl::Critic warnings that we're going to ignore anyway. - x2goserver/lib/x2goupdateoptionsstring: fix interpolated string warning. - x2goserver/lib/x2goupdateoptionsstring: add helper function for transform string interpretation. - x2goserver/lib/x2goupdateoptionsstring: write wrapper that handles program options, creates intermediate, passes through transform chains, reconverts to a string and prints it. - x2goserver/lib/x2goupdateoptionsstring: add debug option and some debugging output. - x2goserver/lib/x2goupdateoptionsstring: remove dead code. - x2goserver/lib/x2goupdateoptionsstring: update documentation and clarify risks of option parsing. It's better to always use -- to terminate program options parsing when no longer needed. - x2goserver/lib/x2goupdateoptionsstring: don't debug-output the intermediate representation if we know that parsing failed. - x2goserver/lib/x2goupdateoptionsstring: fix debug string and add another one dumping the raw options string. - x2goserver/lib/x2goupdateoptionsstring: fix parsing of transformation strings by replacing the switch statement with if statements. "Fallthrough" doesn't mean the same thing as in C, apparently. Buyer beware. - x2goserver/lib/x2goupdateoptionsstring: handle options in a more robust way. First, we scan for unknown options and error out. If we find a separating "--" pseudo-option, we keep that in mind and will not process further options next time. Do this for every run of the transformation loop. - x2goserver/lib/x2goupdateoptionsstring: fix another Perl::Critic nit. - x2goserver/lib/x2goupdateoptionsstring: move into x2goserver/bin, since it's really a standalone program and also useful for non-X2Go-internal usage. - x2goserver/Makefile: add x2goupdateoptionsstring POD-to-man-page handling. - x2goserver/Makefile: don't quote POD_SCRIPTS, because of... make. - x2goserver/Makefile: install man1 files and dirs, too. - x2goserver/bin/x2goruncommand: fix typo in IceWM branch. - X2Go_in_progress_do_not_use/Server/DB/MySQL.pm: backport kdrive change. - x2goserver/bin/x2gostartagent: fix quoting. - x2goserver/bin/x2gostartagent: adapt debug message to ${AGENTBIN} usage. - x2goserver/bin/x2gostartagent: also use ${AGENTBIN} in shadow session code. - x2goserver/bin/x2goruncommand: fix syntax. - x2goserver/Makefile: allow auto-generation of files, including installation, uninstallation and cleanup. - x2goserver/bin: rename x2gopath to x2gopath.in. - x2goserver/bin/x2gopath.in: use ${BASH_SOURCE[0]} instead of ${0}... for reasons. - x2goserver/bin/x2gopath.in: rework quoting, variable usage, drop unnecessary semicolons etc. - x2goserver/bin/x2gopath.in: hardcode LIBDIR, PREFIX and SHAREDIR at build time, but also allow re-rooting afterwards - derived from the original values. - Makefile: specify SHAREDIR as a default-if-not-specified variable. - Makefile: same change, but for ETCDIR. - {libx2go-server-db-perl,x2goserver{,-{common,desktopsharing,extensions, fmbindings,printing,x2goagent, xsession}}}/Makefile: apply default-if-not-specified-logic to all the other Makefiles as well. - x2goserver/Makefile: add support for $(NXLIBDIR). - x2goserver/bin/x2gopath.in: switch to bash. - x2goserver/bin/x2gopath.in: fix warning message to also include SHAREDIR. - x2goserver/bin/x2gopath.in: add and use support for NXLIBDIR; drop the lib-subdir detection. - x2goserver/bin/x2gopath.in: use [] instead of test, for consistency. - x2goserver/Makefile: remove indirections, not needed any longer and leading to build failures now. - x2goserver/Makefile: fix "inline" commenting syntax. Wrapping everything as one string leads to the shell interpreting it as a verbatim command, which will fail execution. Dropping quotes SHOULD™ work, but doesn't, because the outer shell is treating as a comment for itself - leading to it ignoring everything else on that line, including the closing parenthesis. Escaping the hash char only leads to the initial situation with it being parsed as a comment. Backticks would work, but are ugly. Hence, just use the colon pseudo-command. - x2goserver/Makefile: fix syntax error due to non-duplicated dollar signs in comment lines. - x2goserver/Makefile: export common variables for direct use in shell script sections. - x2goserver/Makefile: build up sed argument line as an array and use one substitution run. Multiple runs with the template file as input will lead to only the last replacement to stick in the resulting generated script, which is not what we want to have. Correctly doing that with multiple runs would require the usage of temporary files, which is needlessly complicated in this context. - x2goserver/Makefile: fix shell quoting issue with newly exported ${DESTDIR} variable. - x2goserver/bin/x2gopath.in: more test -> [] conversion. - x2goserver/bin/x2gopath.in: output warning messages if directories do not exist. - x2goserver-xsession/Makefile: correctly generate Xsession symlinks when building on Devuan. No special conffile handling here since we don't actually build Devuan packages. - x2goserver-xsession/Makefile: same for rt-os. - x2goserver-xsession/etc/Xsession: add support for Slackware in the RPM-based section. - x2goserver-xsession/Makefile: generate RPM-based symlinks for Slackware. - x2goserver/bin/x2gopath.in: more quoting. - x2goserver/bin/x2gopath.in: avoid spurious warning messages by canonicalizing installed path values. - x2goserver/bin/x2gopath.in: avoid double slashes since we now know that paths will be canonical. - x2goserver/bin/x2gopath.in: make xinerama path optional, newer releases don't use it any longer, so failures to find it should not result in a warning message. - x2goserver-common/etc/x2goserver.conf: add x2gocleansessions section and agent-startup-time configurable option, to be set to the allowed time period in seconds between session creation and agent PID insertion into the database. - x2goserver/sbin/x2gocleansessions: fetch and sanity-check x2gocleansessions.agent-startup-time from config file. - x2goserver/sbin/x2gocleansessions: rework comment explaining what a session without an agent PID entry actually means and use the value from x2gocleansessions.agent-startup-time (if valid) instead of a hardcoded value. - x2goserver/sbin/x2gocleansessions: replace time check with PID validity check in check_pid and calls. The time check was really just a workaround to allow the agent to start up after a session was formally created, but we already have such a check in another place. Instead, treat a missing PID, which can only happen during session startup, as a success. - x2goserver/bin/x2goupdateoptionsstring: simplify a for loop a bit. - x2goserver/bin/x2goupdateoptionsstring: fix typo in comment. - x2goserver/bin/x2goupdateoptionsstring: fix typo in print statement syntax. Non-functional. - x2goserver/bin/x2goupdateoptionsstring: update copyright notice. - X2Go/Server/Agent/: add new (stub) file NX/Options.pm as a library version of the options string manipulation code. - x2goserver/bin/x2goupdateoptionsstring: fix man page specification, options string was missing. - x2goserver/bin/x2goupdateoptionsstring: move most code to X2Go/Server/Agent/NX/Options.pm. - x2goserver/bin/x2goupdateoptionsstring: revert for loop simplification. We actually depend on the subtle modification of the args reference variable. - X2Go/Server/Agent/NX/Options.pm: add a lot of documentation. - x2goserver/bin/x2goupdateoptionsstring: update synopsis to include the optional character of a plus sign, but a non-optional character for a minus sign. - x2goserver/bin/x2goupdateoptionsstring: make clear that "additional parameters" are transformations. - x2goserver/bin/x2goupdateoptionsstring: replace occurrences of "option string" with "options string". - X2Go/Server/Agent/NX/Options.pm: replace occurrences of "option string" with "options string". - X2Go/Server/Agent/NX/Options.pm: document that duplicate keys in the input options string are possible and accepted, but actually discouraged and semantically redundant. - X2Go/Server/Agent/NX/Options.pm: whitespace-only in comment. - X2Go/Server/Agent/NX/Options.pm: add and use an enum-like construct as the internal mode selector for transforms. - X2Go/Server/Agent/NX/Options.pm: rename options parameter in transform_intermediate to intermediate. - X2Go/Server/Agent/NX/Options.pm: document key-value pairs with either empty keys or empty (!= non-existent) values. - X2Go/Server/Agent/NX/Options.pm: make sure that intermediates never include undef entries. - x2goserver/bin/x2goupdateoptionsstring: switch to "X2Go/NX Agent" term and make it bold to denote something special. - X2Go/Server/Agent/NX/Options.pm: add new function compact_intermediate, used to remove duplicated and empty elements. - x2goserver/bin/x2goupdateoptionsstring: add new --compact/-c switch to enable the use of compactation. - x2goserver/bin/x2goupdateoptionsstring: document new --compact/-c switch. - x2goserver/bin/x2goupdateoptionsstring: split up GetOptionsFromArray () line. Non-functional. - X2Go/Server/Agent/NX/Options.pm: document the new compact_intermediate () function and its implications. - X2Go/Server/Agent/NX/Options.pm: fix some Perl Critic warnings and silence others. - x2goserver/bin/x2goupdateoptionsstring: fix some Perl Critic warnings and silence others. - X2Go/Server/Agent/NX/Options.pm: grammar/typo fix in comment and improve a different comment. - X2Go/Server/Agent/NX/Options.pm: avoid copying arrays if not necessary when passing to grep and map operations. - X2Go/Server/Agent/NX/Options.pm: rework the lastly modified comment again, the changed explanation didn't match the reality. - X2Go/Server/Agent/NX/Options.pm: fix typos in internal section links. - X2Go/Server/Agent/NX/Options.pm: add newline before __END__, non-functional. - {X2Go/Server/Agent/NX/Options.pm, x2goserver/bin/x2goupdateoptionsstring}: add =pod markers. - {X2Go/Server/Agent/NX/Options.pm, x2goserver/bin/x2goupdateoptionsstring}: update AUTHOR sections with proper links. - X2Go/Server/Agent/NX/Options.pm: fix nxagent man page link. - x2goserver/bin/x2goupdateoptionsstring: considerably simplify while loop logic that iterates over transformations. I have no idea why I thought it had to be so complicated in the first place... - {X2Go/Server/Agent/NX/Options.pm, x2goserver/bin/x2goupdateoptionsstring}: reformat/reflow so that each sentence starts on a proper line. This is particularly interesting for the troff output, since GNU troff's heuristic for generating double spaces (by default) after a punctuation character wouldn't trigger otherwise. Since it has no adverse effects on other generators, let's just do it like that. - X2Go/Server/Agent/NX/Options.pm: replace "treat as" with "treat like". - X2Go/Server/Agent/NX/Options.pm: clear up "logically equivalent but logically very different" situation. - x2goserver/bin/x2goupdateoptionsstring: rename EXAMPLE section to EXAMPLES. - x2goserver/bin/x2goupdateoptionsstring: add links to X2Go::Server::Agent::NX::Options documentation on option strings and transformations. - x2goserver/bin/x2goupdateoptionsstring: document how to cheat and just compact options strings. - x2goserver/bin/x2goupdateoptionsstring: add options terminators to example calls. - X2Go/Server/Agent/NX/Options.pm: document that NUL bytes can only be URL-encoded, but that this not recommended. - X2Go/Server/Agent/NX/Options.pm: typo compactation => compaction. - X2Go/Server/Agent/NX/Options.pm: whitespace-only on fake enum-subs. - X2Go/Server/Agent/NX/Options.pm: add empty BEGIN block in case it's ever needed (and if not, it shouldn't have any side effects anyway). - x2goserver/bin/x2goupdateoptionsstring: add space between link and punctuation character for easier copying. - x2goserver/bin/x2goupdateoptionsstring: better document end-of-options terminator and highlight its importance. - X2Go/Server/Agent/NX/Options.pm: reflow some text. - X2Go/Server/Agent/NX/Options.pm: document other non-printable characters. - x2goserver/bin/x2goupdateoptionsstring: add comment regarding the shift () operations after sanitizing program options. - X2Go/Server/Agent/NX/Options.pm: if ("string") in Perl does something weird in a dualvar sense - it converts a string to a number, which typically evaluates into a plain "0" if it doesn't start with any digits. We actually meant to check against an empty string. Also, change the whole expression to not enclose everything in a negation but rather negate sub-terms as required. - X2Go/Server/Agent/NX/Options.pm: make sure to add/modify elements with an empty string or undef key and an undef value as an empty hash. - x2goserver/bin/x2goupdateoptionsstring: fix parsing of multiple subsequent separating "--" pseudo-options. We just have to make sure to treat subsequent pseudo-options literally and to not just consume them. - x2goserver/bin/x2goupdateoptionsstring: add debug print statements for in-depth examination of program options parsing. - x2goserver/bin/x2goupdateoptionsstring: add mode selection functionality. - X2Go/Server/Agent/NX/Options.pm: port modes "enum" subs to the constant pragma to make the code more consistent with the program wrapper. - {X2Go/Server/Agent/NX/Options.pm, x2goserver/bin/x2goupdateoptionsstring}: update Perl critic overrides to allow the constant pragma and document it and other overrides (unless they are self-explanatory). - x2goserver/bin/x2goupdateoptionsstring: rework mode selection, split out abbreviation parsing into a separate function to take out nesting complexity. This trades off nesting complexity (to some degree) with code complexity. - {X2Go/Server/Agent/NX/Options.pm, x2goserver/bin/x2goupdateoptionsstring}: fix/silence a few Perl::Critic warnings. - x2goserver/bin/x2goupdateoptionsstring: typo fix in output message only. - x2goserver/bin/x2goupdateoptionsstring: remove obsolete comment, we're not using a do block/do-while loop any longer. While the information provided there might be an interesting tidbit, it's not relevant to the code any longer and might actually confuse readers. - X2Go/Server/Agent/NX/Options.pm: undef can't be referenced, so adjust/fix the comments. - x2goserver/bin/x2goupdateoptionsstring: more typo fixes in output messages only. - x2goserver/bin/x2goupdateoptionsstring: generalize code looping through program arguments and split out transformation operation into own subroutine. - {X2Go/Server/Agent/NX/Options.pm, x2goserver/bin/x2goupdateoptionsstring}: enable Unicode handling, as far as possible. - {X2Go/Server/Agent/NX/Options.pm, x2goserver/bin/x2goupdateoptionsstring}: fatalize text coding errors. - x2goserver/bin/x2goupdateoptionsstring: sanitize/convert data in @ARGV. - x2goserver/bin/x2goupdateoptionsstring: add non-functional extraction mode. Needs proper implementation. - x2goserver/bin/x2goupdateoptionsstring: fix syntax and strict mode errors. - X2Go/Server/Agent/NX/Options.pm: simplify error handling by splitting intermediate checking out into a separate subroutine. - X2Go/Server/Agent/NX/Options.pm: rename $options variable to $intermediate in intermediate_to_string () for internal consistency. - X2Go/Server/Agent/NX/Options.pm: document that subroutines and constants that are not marked for export are internal and should not be used. Usually, that should implicitly be clear, but it doesn't hurt to be verbose with a disclaimer. - X2Go/Server/Agent/NX/Options.pm: add extract_element subroutine, used to extract key-value pairs. This one will be exportable, too. Documentation to be done. - x2goserver/bin/x2goupdateoptionsstring: correctly use MIME::Base64. - x2goserver/bin/x2goupdateoptionsstring: actually implement extraction mode. - x2goserver/bin/x2goupdateoptionsstring: don't encode/decode in-place. - {X2Go/Server/Agent/NX/Options.pm, x2goserver/bin/x2goupdateoptionsstring}: explicitly use package foreign package names all across the code for consistency. - x2goserver/bin/x2goupdateoptionsstring: fix typos in documentation and reword misinterpreted-as-options section. - x2goserver/bin/x2goupdateoptionsstring: document mode selection and extraction mode. - x2goserver/bin/x2goupdateoptionsstring: fix error handling for kv-pair extraction. - x2goserver/bin/x2goupdateoptionsstring: add base64 encode and decode helpers, add new --base64 parameter that enabled global use of base64. - X2Go/Server/Agent/NX/Options.pm: actually check for a specific value in the kv-pair filter function if so specified. Big oops. - x2goserver/bin/x2goupdateoptionsstring: extend extraction example for how to check for full key-value pair combinations. - x2goserver/bin/x2goupdateoptionsstring: document the new base64 pseudo-mode. - x2goserver/bin/x2goupdateoptionsstring: an equal sign or space character is mandatory after the -m or --mode switch. - X2Go/Server/Agent/NX/Options.pm: document key-value pair extraction. - x2goserver/bin/x2goupdateoptionsstring: fix some Perl::Critic warnings. - x2goserver/bin/x2goupdateoptionsstring: encode/decode to/from shell locale. - x2goserver/bin: rename x2goupdateoptionsstring to x2gooptionsstring. It's not just modifying it any longer. - x2goserver/Makefile: rename x2goupdateoptionsstring to x2gooptionsstring. - x2goserver/bin/x2gooptionsstring: rename x2goupdateoptionsstring to x2gooptionsstring. - x2goserver/bin/x2gostartagent: fetch the agent PID as early as possible. - x2goserver/bin/x2gooptionsstring: actually default to transformation mode if none was explicitly selected. - x2goserver/bin/x2goresume-session: make (most) non-exported variables lowercase, rename variables to more descriptive names, use typeset all over the place and change the variable type for some variables. Mostly non-functional changes. - x2goserver/bin/x2goresume-session: use global-scope msg variable. - x2goserver/bin/x2goresume-session: update copyright notice. - x2goserver/bin/x2goresume-session: use printf more often instead of the not-so-portable echo builtin. - x2goserver/bin/x2goresume-session: fix err_msg => msg usage. - x2goserver/bin/x2gooptionsstring: replace uses of C<> with B<> in cases where the generated output of the C<> sequence might enclose it in double quotes and creates confusing documentation strings. - X2Go/Server/Agent/NX/Options.pm: same C<>-to-B<> conversion as in the previous commit. - x2goserver/bin/x2goresume-session: simplify where possible, use x2gooptionsstring instead of awk field splitting hackery. - x2goserver/bin/x2goresume-session: fix redirections and make script workable again. Shells do not like redirections like 'filedes'>'file' and interpret 'filedes' as an argument to the program instead of as a file descriptor to be used for the redirection, even though 'filedes' might be something like '2'. - x2goserver/bin/x2goresume-session: fix clipboard handling. The "${clipboard}" variable already includes the "clipboard" key. - x2goserver.spec: escape percent signs in comments, getting rid of warnings in obs-build's spec file parser. - x2goserver-xsession/Makefile: drop useless use of cat, add debugging to see whether symlinks or a directory has been added. - x2goserver-xsession/Makefile: support Tumbleweed with Xresources in /usr/etc. - x2goserver.spec: support UsrEtc(Move) for OpenSuSE Tumbleweed for Xresources symlink. - x2goserver-xsession/etc/Xsession: check for *SuSE via /usr/lib/os-release and /etc/os-release and generally refine checking layout a bit. - x2goserver-xsession/Makefile: Xresources is a file, not a directory. - x2goserver.spec: Xresources symlink stays in /etc/x2go for now, no need to use %{_distconfdir} or the like. - x2goserver-xsession/Makefile: on systems that do not provide a global /etc/X11/Xresources file, create a dangling symlink instead. Unbreaks Debian builds. - x2goserver.spec: add BR: and R: on distribution-release (pseudo-package/provides) for /usr/lib/os-release and /etc/os-release. - X2Go/Server/Agent/NX/Options.pm: fix typo in test comment. - x2goserver/bin/x2goruncommand: add support for KDE Plasma 5 (startplasma-x11). - misc: copyright updates, but for contributors who haven't been active. - misc manpages: pre-release date update. * debian/control: + Build-depend upon lsb-release for distro version detection. + Pull in base64 as a run-time dependency.

[ Oleksandr Shneyder ] * New upstream version (4.1.0.4): - Add support for X2Go KDrive. - x2goruncommand: start Xsession on X2Go KDrive desktops. - x2goterminate-session: terminate x2goruncommand and all processes from the group. - Support for rootless X2GoKdrive sessions. - Setting keyboard layout in rootless X2GoKdrive sessions. - x2gostartagent: save the XDMCP server in the session id. - x2goterminatesession: don't terminate x2goruncommand on XDMCP sessions. - setting keyboard layout by agent start and resuming for kdrive sessions. - remove layout debug output from x2go-resumesession. . [ Orion Paplowski ] * New upstream version (4.1.0.4): - x2goserver-xsession/etc/Xsession: Detect $SHELL from getent passwd and use it to launch the session (on RHEL, SUSE, Gentoo and alike).

[ Ulrich Sibiller ] * New upstream version (4.1.0.4): - x2goserver-x2goagent/etc/keystrokes.cfg: sync with nx-libs 3.5.99.20. Previous version was broken and incomplete. Fixes: #1388. - x2goserver/bin/x2gostartagent: prevent logfile corruption. Both stderr redirection and errors= in the options file wrote to the same file which lead to corruption with lots of debug output. Fixes: #1537. - x2goserver-x2goagent/etc/keystrokes.cfg: sync with nx-libs 3.5.99.26. Previous version was incomplete. Note that this will only work correctly once we actually update to 3.5.99.26 within X2Go, but it doesn't hurt to have the new definitions until then. Fixes: #1538. - x2gostartsession: let x2godialog handle events via NX_CLIENT.

Bug#1228: Ctrl-Alt-T doesn't terminate connection in "local desktop" sessions
by Alexey Nemov 30 May '23

30 May '23

Package: x2goserver Version: 4.0.1.20 Summary: As stated in the wiki https://wiki.x2go.org/doku.php/wiki:advanced:nx-keyboard-shortcuts The action "close_session" should terminate the session. But, pressing Ctrl-Alt-t in a "local desktop" session does not "terminate" the session. Steps to reproduce: 0. Create a new session profile in x2goclient with session type "Connect to local desktop"; 1. Connect to remote computer using this session profile; 2. Press Ctrl-Alt-t at the client. Expected behaviour: The remote desktop window on the client should close, the connection should be terminated. Actual behaviour: The remote desktop window on the client does not close, the connection is not terminated. The following log entries appears in the server's system journal: ``` Oct 26 13:50:39 localhost /usr/bin/x2gosuspend-session[31790]: session with ID alex-50-1508997021_stS1XSHADalexXSHADPP0_dp24 has been suspended successfully Oct 26 13:50:45 localhost su[31900]: Successful su for alex by root Oct 26 13:50:45 localhost su[31900]: + ??? root:alex Oct 26 13:50:45 localhost su[31900]: pam_unix(su:session): session opened for user alex by (uid=0) Oct 26 13:50:45 localhost systemd-logind[508]: New session c99 of user alex.

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.

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).

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.

Bug#1513: X2Go client v4.1.2.x (mswin32) crashes when starting "gitk"
by Stefan Baur 16 Dec '22

16 Dec '22

Hi, I was able to reproduce this bug with the X2Go/NX-Libs packages in EPEL on CentOS7. Using our current nightly builds, the problem is gone. So I would consider it a server-side issue, probably with NX-Libs. There seems to be a bit of a version mismatch between what is in EPEL and what is in heuler (our nightly builds), though. I would hope that the problem fixes itself once we push a new release and EPEL copies it. However, making sure that a release actually fixes the issue requires a closer look at the actual package contents in both EPEL and heuler. It seems EPEL has built its version of NX-Libs not based on our sources but based on source hosted by Arctica, and decided to give the package a higher version number than what we are currently using for the packages in Heuler. So this may cause some further trouble down the road.
