digitally signed x2go client installer package?
by Clark, Morgan 23 Jul '25

23 Jul '25

Hi, This is a note I sent to the x2go-dev list before I managed to find and follow the steps to get myself added to the list. From some back-and-forth with the moderator, it appears that x2go already has a detached signature, but our IT department told me that doesn't work, they need the signature to be embedded in the installer. I gather that the expense of a trusted CA-issued certificate is out of your budget, but it sounded like our IT department would be ok with a self-signed certificate (not ideal but it sounded like that would satisfy the signing requirement). Would it be possible to issue the current Windows release in an internally signed format? ==================================================================== Sometimes, like here, in the corporate world there are restrictions on what software is allowed to be used, and in Dell's case one restriction is that an installer package needs to be digitally signed to verify that the installer we use is in fact the genuine article. Unfortunately the MS Windows installer at http://code.x2go.org/releases/X2GoClient_latest_mswin32-setup.exe does not appear to be digitally signed, so they won't let us use it. Would it be possible to create and publish a Windows installer that is digitally signed by the x2go organization? It's a very useful tool for our environment where most of our work is done on systems remote from our desktops, and is better performing and more capable than any alternative we've found, especially over WAN links. Thanks for considering our request, -Morgan Internal Use - Confidential

Mailman 3.x upgrade
by Mihai Moldovan 14 May '25

14 May '25

Hi This is a mass mail to all X2Go lists. During the past few weeks, I have upgraded the mailing list infrastructure from Mailman 2.1 to Mailman 3.0. All subscriptions and archived messages have been imported. Users will NOT need to resubscribe and will continue to get mails. Apologies for the long downtime, but especially the archive imports took weeks to complete and had to be done twice, since the backend used in the first run wasn't suited to the load and amount of data. Unfortunately, the machine is struggling with the load, and web UI operations sometimes take quite long to complete or even time out completely. Just try to refresh and retry the last operation if you see this happening. We will probably want to upgrade this machine in the future. I'll split this mail up into a user, an administrator and a technical part. Feel free to skip the parts that do not interest you. ************************ * USER-VISIBLE CHANGES * ************************ The old Mailman 2.1 infrastructure was quite basic - consisting of a mostly static HTML-based web interface and statically generated HTML pages for each message in the archives. By contrast, Mailman 3.x is much more complex. The web interface is more fancy and also uses Javascript, the archiver is a separate component known as Hyperkitty and everything is plugged together via a Python-based Django uwsgi web service communicating with an internal REST service. Most importantly, you will have to register to the Django-powered Postorius service to manage your subscriptions. Management is now centralized and you won't get password reminders every month for each individual list. To see a list of all public lists, head to https://lists.x2go.org/postorius/lists/ ( https://lists.x2go.org/ will redirect there). To create an account, use the "Sign Up" button/link in the upper right corner of the page. After you have created an account, you will be able to modify all your subscriptions in one place and all your subscriptions should show up automatically (provided the account you signed up for uses the same email address as your subscriptions). This includes setting digest options, pausing mail transfer, subscribing and unsubscribing. If you do not wish to create an account, you can still join or leave mailing lists by sending messages to nameoflist-join(a)lists.x2go.org or nameoflist-leave(a)lists.x2go.org. nameoflist-subscribe(a)lists.x2go.org and nameoflist-unsubscribe(a)lists.x2go.org are aliases that also work. In this case, you will, however, be unable to change other options. Archives can be found at https://lists.x2go.org/hyperkitty - note that if you're logged in to Postorius, you will also be automatically logged in to Hyperkitty. The archives for a list can also be reached by following the Archive link/button in Postorius's mailing list info page. In order not to break old links, the old archive is also still accessible at https://lists.x2go.org/pipermail/ - albeit in a read-only state that will not be updated any longer. I have added information to the index pages to reflect that. ************************** * ADMINISTRATION CHANGES * ************************** Mailman 3.x allows making users administrators or owners of lists, which can then change settings, tend to held messages and the like. Historically, in Mailman 2.1, administration was based upon a password. I have created a super user account named listadmins(a)lists.x2go.org with the known password. This user is owner of all lists and can be used to manage every aspect. As soon as you are logged in to an account that is either and administrator or owner of one or multiple lists, you can use Postorius ( https://lists.x2go.org/postorius/lists ) to manage settings, held messages and the like. Especially the "held message" interface deserves a bit of explanation. By default, 10 messages are shown per page. Each message can be selected/ticked individually or you can all select all messages in a page at once by using the checkbox left of "Subject" in the table header. Clicking the buttons "Accept", "Reject" or "Discard" will carry out the appropriate action on all selected messages. Note, however, that this will not add the sender to any of the auto-accept, auto-reject or auto-discard lists. In order to also add the sender of a message to a specific auto-action list, click on a message. A javascript-based popup will appear with the whole message text. The popup might not show up instantly, especially if the machine is slow, so please wait after clicking on message! If you get an error about the message not existing, refresh the page and retry. The popup includes two buttons at the bottom to show either the full source of the message or just the headers, which can be very handy. Above the "Rejection reason" text box, a "--- Set member moderation ---" drop down menu can be used to select the desired auto action (hold, reject, discard, accept or default processing). After setting this correctly, use any of the "Accept", "Reject" or "Discard" buttons below the text box to submit the result and carry out the desired action. Django has a special admin interface at https://lists.x2go.org/admin that can be used to manage data in Hyperkitty (the archiver), for instance to delete messages from the archive. Usually, you will not need to use this admin interface. ************************* * TECHNICAL INFORMATION * ************************* Unfortunately, Mailman 3.x is horribly broken by default in Ubuntu 24.04 (c.f., https://bugs.launchpad.net/ubuntu/+source/mailman-suite/+bug/2062960 and other bug reports). The mailman version is too old to be compatible with dependencies it needs, leading to a non-working setup out of the box. Upstream recommends installing mailman via a Python venv, but that would essentially decouple it from the system (and system updates), which I don't like. For this reason, I backported a lot of code to fix the Mailman 3 as installed via the distro packages. However, I've only done so purely on the file system and haven't created modified .deb packages. Please be extra careful when upgrading ymir and please don't update any packages related to Django, Mailman, Hyperkitty or Xapian! This will undo all of my changes and break the whole mailing list infrastructure. I plan on backporting newer versions from Debian Testing or Unstable to Ubuntu 24.04/noble in a proper .deb-based way, but that's not something I can easily do right away. Initially, I set up Mailman and Hyperkitty to use SQLite3 as its database backened, but that turned out to be excruciatingly slow. It's now using the PostgreSQL 16 backend, which works better, but also uses quite a bit of system memory, so the machine's swap space is always in use. When upgrading PostgreSQL in the future, the databases will also need to be migrated correctly. Hyperkitty can optionally use a full-text search engine to provide better search capabilities. Initially, I used Whoosh, but it turned out to be rather resource hungry and, unfortunately, also slow. We're now using Xapian with a fix for long terms, which unfortunately has not been applied upstream yet. ( https://github.com/notanumber/xapian-haystack/pull/238 ) I've enabled Markdown rendering mode in Hyperkitty for x2go-announcements, x2go-dev, x2go-user, x2go-user and x2go-i18n. This crashed badly on some mails yesterday, but should now fall back correctly to the basic text renderer in case of failures. Mihai

Bug#1633: New clipboard issue in Libreoffice with X2Go
by Jens Reyer 07 Apr '25

07 Apr '25

Package: x2goserver Version: 4.1.0.6-1.1+b1 Severity: normal Hi, since an update/reinstallation copy&pasting in Libreoffice in X2Go always needs to be repeated, only the very first run works instantly. We found this issue only when using X2Go, but not when working directly on the same machine. It happens only in Libreoffice (Calc and Writer), but not in e.g. Firefox or an editor. Starting Libreoffice in safe mode (soffice --safe-mode) does not help. Steps to reproduce: Start Libreoffice ctrl+c, ctrl+v OK ctrl+c, ctrl+v FAIL (nothing is inserted) ctrl+c, ctrl+v FAIL (nothing is inserted) Start Libreoffice right-click > copy, right-click > paste OK right-click > copy, right-click > paste FAIL (Libreoffice Calc asks where to shift the cells, but then nothing is inserted) right-click > copy, right-click > paste FAIL (Libreoffice Calc asks where to shift the cells, but then nothing is inserted) Workaround: ctrl+c, ctrl+v OK ctrl+c, ctrl+c, ctrl+v OK ctrl+c, ctrl+c, ctrl+v OK Tested affected servers: Debian Trixie/Sid Mate (libreoffice 4:24.8.5-2 amd64, x2goserver 4.1.0.6-1.1+b1) LinuxMint 22.1 Mate (libreoffice 4:24.2.7-0ubuntu0.24.04.2, x2goserver 4.1.0.6-1.1build1) Previously not affected server: LinuxMint 21.3 Mate (libreoffice 1:7.3.7-0ubuntu0.22.04.8, x2goserver 4.1.0.3-5) Tested Clients: Debian Trixie (x2goclient 4.1.2.3-3) Linuxmint 22.1 (x2goclient 4.1.2.3-1build3) Win10 (X2GoClient 4.1.2.2), with the X.org server option "do not use primary clipboard" both checked and unchecked I reported this issue only here, not with the distros or Libreoffice. Please tell me if I should otherwise or if I should provide additional info or tests. My boss is willing to pay for a solution. Just contact me. Thanks in advance and thanks for all your work!

x2go connection failure: Protocol mismatch or no X authentication data

x2go Windows client crashes with Putty Pageant with long RSA 4096 keys
by Gerhard Wiesinger 05 Feb '25

05 Feb '25

Hello, I'm having a crash problem with latest version (also previous ones) with ssh private key authentication and Putty Pageant. Looks like there is a buffer overflow involved. With several smaller keys (e.g. ssh-ed25519) it works well. I found a scenario to reproduce it: 1. Generate a RSA 4096 Bit length private/public key pair 2. Load it on the Windows client into Putty Pageant 3. Put public key at the server at ~/.ssh/authorized_keys 4. open connection to the server => crash, see logs Looks like it is a bug in the old libssh library version with large private/public keys. Can you please fix the topic. Some questions: - Is the used libssh version really version 0.9.2? - The logs have some entries with: agent_talk - len of request - That has been changed in git to another logging in 2011: https://git.libssh.org/projects/libssh.git/commit/?id=ba4f10dc4657952ec47f7… - Version 0.9.2 has been released in 2019: https://www.libssh.org/2019/11/07/libssh-0-9-2/ - So it looks, not the version 0.9.2 is used - Any plans to upgrade to latest version of libssh 0.11.0 while keeping Putty Pageant Agent support? - Upgrade plans to newer Putty version? - Is there a newer nightly Windows build from newer git sources available?

patch: fix for session breakage on resume
by Christian Inci 05 Feb '25

05 Feb '25

Hi, Something that got an update in Gentoo's portage in the last month or so causes interference/crashes on session resumption, next to/besides the usual and various overall crashes. Those new crashes appear with a roughly 80% chance and result in the "new_agent_options_base64" variable being empty, thus emptying the "options" file, leading to the session being utterly destroyed. Just backing the file up and restoring it when that happens won't help, because x2goagent will go into a loop, flooding the logfile with the same line exactly 20 times per second until the session is terminated. With this patch everything works fine again after another resume attempt. diff --git a/x2goserver/bin/x2goresume-session b/x2goserver/bin/x2goresume-session index dd59019e..694735eb 100755 --- a/x2goserver/bin/x2goresume-session +++ b/x2goserver/bin/x2goresume-session @@ -321,7 +321,9 @@ if [[ -z "${x2go_client}" ]]; then x2go_client="${current_host_name}" fi +if [[ -n "${new_agent_options_base64}" ]]; then printf '%s' "${new_agent_options_base64}" | base64 -d >"${session_dir}/options" +fi # run x2goserver-extensions for pre-resume x2gofeature 'X2GO_RUN_EXTENSIONS' &>'/dev/null' && x2goserver-run-extensions "${session_name}" 'pre-resume' || true

Sunday, Dec 29th - Last X2Go and orca e.V. Sponsorship Drive for 2024
by Vorstand ORCA e.V. 28 Dec '24

28 Dec '24

Dear $ALL, We hope you had some happy, relaxing and peaceful holidays over the last few days. As a quick reminder, tomorrow would be a good time to help out X2Go (and orca e.V.) financially. While we have received some donations to the general X2Go donation pool, which we can reassign as needed, donations towards our event budget have stalled for the last 5 months or so - only one recent donation has since shown up. This budget is used to cover costs for having handouts/posters printed for our booths, as well as travel/accommodation costs for our volunteers. It would be really cool if you could send some $$$/€€€/£££/¥¥¥ our way, so we can reimburse our volunteers, who have been covering all the costs up-front our of their own pockets. 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. Until December 29th, non-recurring donations up to 100 Euro made on any Sunday during December 2024 will be matched by Betterplace with an additional 15%. This offer is only valid until a funding pool of 4 000 Euro is depleted (per Sunday). So the earlier you donate on these Sundays, the higher the chance that your donation will receive the bonus. As tomorrow is the last of those Sundays, we hope you are willing and able to chip in, so we can keep hosting and attending events like these. To donate towards X2Go's events (posters, handouts, travel, lodging, …), please use one of these links: * English-language donation form: <https://www.betterplace.org/en/projects/131360?wirwunder=235> * German-language donation form: <https://www.betterplace.org/de/projects/131360?wirwunder=235> Further donation links (infrastructure, X2Go in general, orca e.V.) can be found right at the very top of the X2Go Wiki: <https://wiki.x2go.org/> 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. Another way to help us is to be vocal about what you need X2Go for and how it would hurt you if it would no longer be available - we're trying to apply for public funding, so if you're using X2Go in the public sector (i.e. education, research, health care, energy, industry), please do let us know how X2Go ceasing to exist would affect you. Kind Regards, Stefan Baur, first chairman of the board, Open Remote Computing Association - orca e.V.

X2Go: The Spread 2024 recordings online/X2Go and orca e.V. Sponsorship Drive
by Vorstand ORCA e.V. 14 Dec '24

14 Dec '24

Dear $ALL, Some of you might have missed it, as it wasn't announced on the mailing lists, only on the Wiki, due to massive time constraints/understaffing, but - we did indeed have an X2Go: The Spread 2024 virtual event. Which makes 2024 the first, and probably the only year where we had both an in-person/hybrid "X2Go: The Gathering" and a virtual "X2Go: The Spread" event. You can read up about what you've missed on <https://wiki.x2go.org/doku.php/events:x2go-spread-2024>, where you will find links to recordings of each day (save for Thursday - that was a live debugging session, so we didn't bother recording it). Here's a quick overview of the presentations/discussions: Monday * X2Go's State of the Union, Part 2 (Part 1 was presented at X2Go: The Gathering 2024) * X2Go's Funding Situation, Part 1: Sovereign Tech Fund Tuesday * Demo: Portable DHCP proxy with X2Go-TCE-live Netboot (a follow-up to X2Go: The Spread 2023's Thursday presentation) * Progress Report re: KDrive on arm64 * OSUOSL Behind-The-Scenes Update Wednesday * X2Go's Funding Situation, Part 2: orca/Betterplace * Gitlab Status Report Thursday * KDrive debugging Friday * Secure Remote Access Even to Old Windows XP Systems - Thanks to X2Go and a Raspberry Pi * NX-libs update * “Mr. Eyebot V2.0” - Quick Explanation and Demo Or, if you want to watch all recordings back to back, head straight over to YouTube, where we have prepared a playlist for you: <https://youtube.com/playlist?list=PLWDo4PkY3E0My_exV1bT7z5vOA63P5mqN&featur…> If you like what we're doing, now would be a good time to help us out financially. While we have received some donations to the general X2Go donation pool, which we can reassign as needed, donations towards our event budget have stalled for the last 5 months or so. This budget is used to cover costs for having handouts/posters printed for our booths, as well as travel/accommodation costs for our volunteers.

Upcoming X2Go and orca e.V. Sponsorship Drives - Starting Tomorrow, 2024-12-01
by Vorstand ORCA e.V. 30 Nov '24

30 Nov '24

Dear $ALL, As we're approaching the end of the year, we can't help but notice that X2Go is running low on funds. We are still in need of almost 300 EUR to cover this year's hosting costs, and we're a good 2 100 EUR short in the "events" category, covering costs relating having handouts/posters printed for our booths, and travel/accommodation costs for our volunteers. 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, but also to keep our servers running. 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. There are two sponsorship drives coming up, the first of them starting tomorrow: 1) Non-recurring donations up to 100 Euro made on any Sunday during December 2024 will be matched by Betterplace with an additional 15%. This offer is only valid until a funding pool of 4 000 Euro is depleted (per Sunday). So the earlier you donate on these Sundays, the higher the chance that your donation will receive the bonus. 2) Non-recurring donations up to 100 Euro made on Friday, 2024-12-06 (starting 09:00 CET and ending 23:59 CET) will be matched 100% by the Commercial and Savings Bank Ulm.

Patch for x2gohtmlclient
by Dj ZU 20 Aug '24

20 Aug '24

Hi team, Thank you for the development of X2go, I'm using Kdrive on the Windows client on a daily basis and very happy with it!

X2Go: The Gathering 2024 (2024-06-28 to 2024-06-30) will take place at Linuxhotel, Essen, Germany
by Vorstand ORCA e.V. 23 May '24

23 May '24

Dear $ALL, As stated in the subject line, X2Go: The Gathering 2024 will take place at Linuxhotel, Essen, Germany, from Friday afternoon, 2024-06-28, to Sunday afternoon/evening, 2024-06-30 and will, again, be a three-day "work and play" (coding, chatting, sightseeing, socializing) event. X2Go: The Gathering is the annual event where users, admins, and developers (including the i18n volunteers) of X2Go meet face to face, to discuss current X2Go-related issues, fix open bugs, and have a good time getting to know each other. As there is some overlap between X2Go, Arctica, and orca e.V., you can expect to see members of those groups as well. After 4 years spent "in exile" (with a skeleton crew of volunteers meeting at shackspace in 2020, and going completely virtual in the years 2021-2023) due to the pandemic situation, we are finally returning to a full real-life event at Linuxhotel (though we will be streaming/recording our sessions, so you can join in remotely as well). Note that while we do not require masks to be worn, it is still recommended and endorsed, especially in indoor areas. At the time of writing this invitation, and using some educated guesses regarding under-reporting and wastewater analysis, Covid infection rate in Germany is roughly somewhere between 1 out of 1000 and 1 out of 500 people per week. *ATTENTION!* If you want to join us *and* want to sleep in one of the hotel rooms at the Linuxhotel, we need the number of beds and nights you want to reserve, as well as *your full name* (as printed on your passport) and *your nationality* by *2024-06-07* *23:59:59* *CEST*!!! Very important!!! After that date, we cannot guarantee that we will still be able to reserve a room for you! First come, first serve! As single rooms are in short supply, please book your bed in a 2- or 3-bed room, unless you absolutely have to use a single room. Please send your reservation request to <mailto:vorstand@orca-ev.de> with the text "The Gathering" somewhere in the subject and bug me publicly on the X2Go-Project list if you don't receive a confirmation by e-mail after a day or two. If for some reason or other you do *not* need a place to sleep at Linuxhotel, but *do* want to join us, please *still* let us know in advance that you're planning to visit. There's no such hard deadline as for the room reservations, but you will need to "check in" (and there will be an "Admission fee") for our gathering with the Linuxhotel staff, so please *do* let us know in advance. We will be updating the Wiki page <http://wiki.x2go.org/doku.php/events:x2go-gathering-2024> as more information becomes available. We already have one sponsor for the event - CFD.direct have kindly offered to sponsor the Pizzas on Friday evening - but the more, the merrier, so if you know someone willing and able to co-sponsor the event, please let us know at <mailto:vorstand@orca-ev.de> as well. Whether they wish to send us some "swag" with their company branding, or pledge money that we can use to lower dining and lodging costs for our participants (or to lower their health risks by providing masks, sanitizers and free testing), their sponsorship is greatly appreciated. Sincerely, Stefan Baur, "X2Go: The Gathering" event organizer

Next Event/Upcoming X2Go and orca e.V. Sponsorship Drive - Starting Tomorrow, 2024-03-26, to 2024-03-28
by Stefan Baur 25 Mar '24

25 Mar '24

Dear $ALL, X2Go will be present at Linux-Info-Day <https://www.luga.de/static/LIT-2024/> in Augsburg, Germany on Saturday, April 20th. At this event, 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. We're still waiting to hear back from the Linux-Info-Day crew regarding a talk slot - we have submitted a CfP for a talk regarding how to incorporate SSH, 2FA and X2Go into a simple, but effective Ransomware protection for vintage as well as current Microsoft Windows versions. If you're planning to attend and/or are in the area, feel free to stop by and say hi! Attendance is free, and you do not need to register beforehand. 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*. Sadly, funding for X2Go events has tanked since we separated it from the main X2Go donation pool - we haven't received a single donation for our event budget yet. Which means that not only the trip to Linux Info Day is still in need of funding, but also the previous one to Linux Days Chemnitz. :'( The situation for our infrastructure budget is a little better, but we could use some help there as well. You can find our donation pages here: X2Go Events (English): <https://www.betterplace.org/en/projects/131360?wirwunder=235> X2Go Events (German): <https://www.betterplace.org/de/projects/131360?wirwunder=235> X2Go Infrastructure (English): <https://www.betterplace.org/en/projects/131358?wirwunder=235> X2Go Infrastructure (German): <https://www.betterplace.org/de/projects/131358?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 e.V., our umbrella org) are usually tax deductible for German tax subjects. Note that there is a special sponsorship drive sponsored by the Commercial and Savings Bank Ulm, where the orca (and thus X2Go) bank account resides: Projects receiving donations made between Tuesday, 2024-03-26 (starting 09:00 CET) and Thursday, 2024-03-28 (ending 23:59 CET) will receive additional funding from a pool of 10 000 Euro. So the more you donate during this timeframe, the higher the share we'll receive from those 10 000 Euro. 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/1772238185239634302> (English) <https://twitter.com/farbenstau/status/1772239658727968852> (German) If you're on BlueSky, you can reskeet and like the following to help: <https://bsky.app/profile/farbenstau.bsky.social/post/3kojhnqvcn423> (English) <https://bsky.app/profile/farbenstau.bsky.social/post/3kojhzohqz423> (German) And on Mastodon, you can like and boost the following to help: <https://infosec.exchange/@farbenstau/112156390300051818> (English) <https://infosec.exchange/@farbenstau/112156394812114108> (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

x2goruncommand is not exiting after logout in some distros
by Oleksandr Shneyder 20 Mar '24

20 Mar '24

Hi all, who wrote this in /usr/bin/x2goruncommand?: --------------------------------------------- # This is gonna be a nasty trick now... # Most applications run in foreground (fine!), but some fork to background (urgghh... e.g. konsole, iceweasel, etc.). # By capturing their STDOUT, we force the process to remain in (sort of) foreground until the process has finished. # This works fabulously with all applications that don't cleanly close their file descriptors (which is probably # 99% of all applications out there...). STDOUT=`$EXEC_WRAPPER $cmd$args` ------------------------------------------------ looks like some DEs for example XFCE and Plasma on Ubuntu22 and Alma9 starting some processes which are occupying stdout and not terminating them after logout. As result after logout user have a blank screen which stays forever, that can be very confusing. We should remove it at least for desktop sessions. Replacing the line STDOUT=`$EXEC_WRAPPER $cmd$args` with $EXEC_WRAPPER $cmd$args fixing the problem. regards, Alex -- ----------------------------------------------------------- Oleksandr Shneyder | Email: o.shneyder(a)phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Schleiermacherstr. 2 | Fax. : 0911 - 14870374 9 D-90491 Nürnberg | Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Client build question
by Hauke Fath (SPG) 20 Mar '24

20 Mar '24

Hi, by way of an introduction: I maintain the x11/x2go-client package on pkgsrc (<https://pkgsrc.se/x11/x2go-client>). The package has a few patches, which you may be interested in. While updating to 4.1.2.3, I stumbled over a build problem: In <https://gitlab.x2go.org/x2go/client/x2goclient/-/commit/fc2db75ab86889cdde6…>, the MAKEOVERRIDES variable is supposedly set to a list of make variables that are safe to propagate to sub-make processes.* I find that this breaks the build, since gmake (v4.4.1 here) interprets the first word ("SHELL") as target, which it cannot find. Coincidentally, the Arch package <https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=x2goclient> also has a sed(1) command that cleans out the lists. What was the motivation of the change? And where does it actually work? Cheerio, Hauke * The *BSD variants are rather pointless, btw, since the rest of the Makefile has non-portable constructs and won't work at least with NetBSD's make(1) -- The ASCII Ribbon Campaign Hauke Fath () No HTML/RTF in email Institut für Nachrichtentechnik /\ No Word docs in email TU Darmstadt Respect for open standards Ruf +49-6151-16-21344 -- The ASCII Ribbon Campaign Hauke Fath () No HTML/RTF in email Institut für Nachrichtentechnik /\ No Word docs in email TU Darmstadt Respect for open standards Ruf +49-6151-16-21344

Bug#850: Better Mouse Pointer Handling for Shadow Sessions

Bug#1269: X2go server crashes on Ubuntu 16.04 starting at 2018-03-08
by krehberg＠aol.com 30 Jan '24

30 Jan '24

Package: nxagent Version: 3.5.99.15 (From the Official Ubuntu PPA) Hello, X2go server crashes on Ubuntu 16.04 starting at 2018-03-08. I am using Windows 10 as the client. It happens most often when moving the window from one display screen to a second one. It also happens after a short time online, usually fewer than 5 minutes. Perhaps a recent Windows 10 update may have caused this since that's the only thing I have changed on these systems. I am also mounting my Windows 10 drive through the X2go client. Sound is disabled. I'm pretty sure nxagent was updated on March 8 to this version: NXAGENT - Version 3.5.99.15 Here is what I see in the kernel log (dmesg): [ 194.802419] nxagent[3035]: segfault at 0 ip 0000559edeb9c5fb sp 00007ffcbebf71c0 error 4 in nxagent[559edead1000+432000] [ 9277.059883] nxagent[23367]: segfault at 0 ip 0000562497ecb5fb sp 00007ffcd24230b0 error 4 in nxagent[562497e00000+432000] [ 9319.625785] nxagent[24275]: segfault at 0 ip 0000557f7e17f5fb sp 00007ffd7cbda740 error 4 in nxagent[557f7e0b4000+432000] [ 9696.220810] nxagent[25857]: segfault at 0 ip 00005607d52375fb sp 00007ffc87afbb40 error 4 in nxagent[5607d516c000+432000] [ 9750.298187] nxagent[26894]: segfault at 0 ip 000055c8f5dbd5fb sp 00007ffef53ee0e0 error 4 in nxagent[55c8f5cf2000+432000] I don't see anything remarkable on the Windows 10 side. Thank you for your efforts. Kris Rehberg

Bug#879: CVE backports incomplete or wrong
by Ulrich Sibiller 30 Jan '24

30 Jan '24

Package: nx-libs Recently a lot of CVE fixes have been added to nx-libs. E.g. debian/patches/1027-render-check-request-size-before-reading-it-CVE.full.patch and debian/patches/1028-render-unvalidated-lengths-in-Render-extn.-swap.full.patch add missing checks to nx-X11/programs/Xserver/render/render.c. However, there's a file called nx-X11/programs/Xserver/hw/nxagent/NXrender.c which is derived from render.c and in that file those checks are missing, too. (I suspect the original render/render.c is not used at all in favour of hw/nxagent/NXrender.c but I am not 100% sure here.) If render.c is used a all (I am not sure) the patches should be extended to also fix NXrender.c. If render.c is not used it should be removed and the patches should be applied to NXrender.c instead. There might be more cases like this, I only picked this one as an example.

Bug#866: Fix compilation errors in nxcomp (nx-libs) when macros TEST/DEBUG/... are defined (developer support)
by Nito Martinez 30 Jan '24

30 Jan '24

Package: nx-libs Version: 3.5.0.28 Description: The attached patch fixes some compilation errors when the following macros are enabled: (TEST/DEBUG/DUMP). See the lines: #undef TEST #undef DEBUG ... and the conditinal ifdefs #ifdef TEST #ifdef DEBUG ... which are normally not compiled. During debugging and testing when these macros gets activated, there are some compilation errors, which need to be manually fixed each time the Macros are enabled. This patch tries to leverage that error. The patch does not affect code outside of those ifdef, and only provides developer support. Regards, Nito

Bug#865: New API call for nxcom (nx-libs) NXTransCleanupForReconnect
by Nito Martinez 30 Jan '24

30 Jan '24

Package: nx-libs Version: 3.5.0.28 Description: The following patch includes support for a new API call NXTransCleanupForReconnect, which basically clears the state of nxcomp proxy side (modified nxproxy), so that a reconnection is possible. Rationale: Usually nxproxy clears the status of the connection by doing an exit and launching a new nxproxy. This strategy does not work for applications in IOS which do not allow forking. Special care has been taking to not modify any of the other nxcomp code. Regards, Nito

Bug#829: Screen resize triggers session suspension

Only affects full sessions - users are not affected if running directly an APPLICATION. Pressing CTRL+ALT+R triggers error message in session.log of user, resizes the screen but also triggers suspension of the session (note the the Proxy-Warning does not occur every time): Session: Resuming session at 'Thu Mar 26 11:11:56 2015'.

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#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.
