Trying to raise a bug issue and workaround - where?
by Joshua Kite 18 Feb '26

18 Feb '26

I have found a bug and workaround in x2goclient on MacOS Sequoia. I am trying to raise report/this but where? The official wiki advice <https://wiki.x2go.org/doku.php/wiki:bugs> suggests applying to join the GitLab org - I've applied but I have to wait for admin approval. There's an IRC/Matrix channel <https://wiki.x2go.org/doku.php/contact:start>where it was suggested I also join the mailing list. The bugs mailing list <https://lists.x2go.org/listinfo/x2go-bugs> does not appear to have been active for a decade <https://lists.x2go.org/listinfo/x2go-bugs> although I have subscribed. A kind soul on IRC suggested also joining this mailing list but I am not sure that this is the right place to raise a bug report. Without meaning to be rude about a great software project, the situation does seem a bit ridiculous. I run my own (much, much smaller) open source project onGitHub and if people want to raise an issue then they can just do that, ditto me for many of the other open source software projects I use. It's unfortunate that there isn't a clear and straightforward way here. If anyone is able to comment on the correct route to raise an issue/bug then I should be grateful, thanks Joshua

x2go does not show the remote desktop I invoke
by Athanasios Silis 20 Jan '26

20 Jan '26

Hi all, I recently installed x2goserver (and x2goclient but this is probably not relevant in this case) on a fresh slackware-current system. Then, using x2goclients from other computers (other slackware64-15.0, ubuntu20.04 and 24.04 and debian systems) I want to "fetch" a desktop from this fresh system to one of the other client systems. The connection seems to go through normally but I never see a desktop window poping up. I have tried "xfce" and "fluxbox" (as a custom command) both of which have been faithfully working in the past and in other installations. I used `x2goclient --debug` to invoke the session and see if there are any meaningful messages error messages from the client side, but I have not been able to figure out if there is anything relevant: $ x2goclient --debug qt5ct: using qt5ct plugin x2go-INFO-1> "Starting X2Go Client 4.1.2.2..."

I am also very confused about the "ssh_channel_open_session failed": "Socket error: Success" I have not found any information about how to enable debug output in the server side (only on the client side) and the current messages do not give me a clear view as to what is wrong. Do you have any idea which way I should look next? Thank you in advance for your help.

Lubuntu session with X2Go
by Kalle Tuulos 03 Nov '25

03 Nov '25

Hello all My computer runs Lubuntu 24.04. When I use it locally, these sessions are available: "Lubuntu", "LXQt Desktop" and "Openbox". The "Lubuntu" session is the nicest of these. The "LXQt Desktop" is very basic and clean, it does not have the same themes etc as the "Lubuntu" session has. Has someone managed to initiate a "Lubuntu" session over X2Go, as there is no ready-made "Lubuntu" option in the Session type list? I have tried to create my own wrapper script, which would export the "DESKTOP_SESSION" variable as "Lubuntu" before calling startlxqt, but this did not do the trick, the session is still the plain LXQt. Thanks Kalle

OpenGL support?
by Brian 24 Aug '25

24 Aug '25

Hello, Long-time x2go user, just now decided to chase this problem I've been having for a couple years. Server is x2goserver 4.1.0.6-0x2go1+git20230818.1994+12.main.1 on Debian 12.8. Client is X2Go Client v. 4.1.2.2 (Qt -4.8.6) on Windows 10. I am using "single application" mode along with uLauncher to create a mostly-seamless remote X experience. Unfortunately, if I launch any application that attempts to create an OpenGL context, x2goserver crashes instantly. I cannot even run "glxinfo" within the x2go session, although I can use a direct SSH terminal to run it in indirect render mode against the x2go display. Doing so gives the output in the included text file. This stops me from doing anything with any applications that require accelerated 3D graphics, such as FreeCAD, KiCAD, and a variety of games. It's not so bad that I can't run a game; that would be a terrible experience. But it is bad that x2goserver completely crashes. Should this work at all? I guess x2goserver shouldn't crash, in any case. I see what look like relevant core dumps in journalctl, but I don't know how to gather that up to provide here. What debugging information do I need to provide? Thanks, -Brian

Configure alternate ssh client config file???
by mike＠musicplace.com 24 Jul '25

24 Jul '25

I've added some configuration options to my personal ".ssh/config" client configuration on my linux client which are newer than the libssh file used by x2go. Specifically, the "Tag" feature, which turns out to be really useful to me. However, x2go gives "Failed to process system configuration files" error. Testing confirms the problem is with the new options in the ssh config file. My Question: Is there a way to provide options to the ssh command issued by x2go? Specifically of course I'm thinking of the "-F <configfile>" option that specifies an alternative per-user configuration file. Thanks in advance, Mike

http proxy server for X2Go client
by nf.xgo2025＠emimx.com 29 May '25

29 May '25

Hi everybody, I am trying to set-up an nginx server as http proxy for the x2go client. My x2go server is a VM on a private network 10.10.10.201. So far I have been using an ssh tunnel to reach the server from outside via ssh on the host. The host runs an nginx server that is connected to the internet. I would like to use nginx as the http proxy to the ssh instance running on the VM. However, when I set "Use proxy server for http connection" and put the host sshproxy.mydomain.com and port 80 in the client, I alwas get the error message: "Cannot connect to proxy server". Nginx does not show any access in the log. Here is my Nginx configuration: server { listen 80; server_name sshproxy.mydomain.com; access_log /var/log/nginx/sshproxy-access.log; error_log /var/log/nginx/sshproxy-error.log warn; auth_basic "Restricted"; auth_basic_user_file htpasswd; location / { proxy_pass http://10.10.10.201:22; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $host; proxy_read_timeout 3600s; proxy_send_timeout 3600s; proxy_connect_timeout 3600s; } } Can anyone help me to get this working?

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

Hey, I've been using x2go under opensuse 15.5 and have been happy. Unfortunately it stopped working with 15.6. When I run x2gclient --debug &. I get the following messages: x2go-DEBUG-../src/sshmasterconnection.cpp:1810> Locking SSH channel connection MUTEX. x2go-DEBUG-../src/sshmasterconnection.cpp:1812> Passing new channel connection object to channelConnections. x2go-DEBUG-../src/sshmasterconnection.cpp:1814> Unlocking SSH channel connection MUTEX. x2go-DEBUG-../src/sshmasterconnection.cpp:1977> Creating new channel. x2go-DEBUG-../src/sshmasterconnection.cpp:1990> New channel:0x7f1484017370 x2go-DEBUG-../src/sshmasterconnection.cpp:2065> Executing remote: "bash -l -c 'echo \"X2GODATABEGIN:bedcda46-d323-4aca-a487-221e35ec8f97\"; export PATH=\"/usr/local/bin:/usr/bin:/bin\";expo rt TERM=\"dumb\"; echo \"default-server=localhost:41357\" > \"${HOME}/.x2go/C-sevi-67-1742738181_stRkate_dp32/.pulse-client.conf\";echo \"cookie-file=${HOME}/.x2go/C-sevi-67-1742738181_stRk ate_dp32/.pulse-cookie\" >> \"${HOME}/.x2go/C-sevi-67-1742738181_stRkate_dp32/.pulse-client.conf\";echo \"autospawn=no\" >>\"${HOME}/.x2go/C-sevi-67-1742738181_stRkate_dp32/.pulse-client.co nf\"; echo \"X2GODATAEND:bedcda46-d323-4aca-a487-221e35ec8f97\";'" x2go-DEBUG-../src/sshprocess.cpp:310> Copying file via SshProcess object 5: "/home/sevi/.config/pulse/cookie" -> "$HOME/.x2go/C-sevi-67-1742738181_stRkate_dp32/.pulse-cookie" x2go-DEBUG-../src/sshprocess.cpp:387> Starting tunnel via SshProcess object 6: "localhost":41357 -> "127.0.0.1":4713 x2go-DEBUG-../src/sshmasterconnection.cpp:426> Requesting reverse tunnel from port 41357 to 4713 x2go-DEBUG-../src/onmainwindow.cpp:6618> Proxy wrote on stderr: "\nNXPROXY - Version 3.5.99.26\n\nCopyright (c) 2001, 2011 NoMachine (http://www.nomachine.com <http://www.nomachine.com>)\nCopyright (c) 2008-2014 Olek sandr Shneyder <o.shneyder(a)phoca-gmbh.de>\nCopyright (c) 2014-2016 Ulrich Sibiller <uli42(a)gmx.de>\nCopyright (c) 2014-2016 Mihai Moldovan <ionic(a)ionic.de>\nCopyright (c) 2011-2016 Mike Gabr iel <mike.gabriel(a)das-netzwerkteam.de>\nCopyright (c) 2015-2016 Qindel Group (http://www.qindel.com <http://www.qindel.com>)\n\nNXCOMP, NX protocol compression and NX extensions to this software\nare copyright of the aforementioned persons and companies.\n\nRedistribution and use of the present software is allowed according\nto terms specified in the file LICENSE.nxcomp which comes in the\nsource di stribution.\n\nAll rights reserved.\n\nNOTE: This software has received contributions from various other\ncontributors, only the core maintainers and supporters are listed as\ncopyright hol ders.

snaps don't work on x2go
by olafs6＠gmx.de 03 Feb '25

03 Feb '25

Hello! I'm currently testing x2go with a fresh install of Ubuntu on Proxmox. When accessing via x2go, many applications do not work, such as firefox and chromium. When you start the terminal you get the message /user.slice/user-1000.slice/session-401.scope is not a snap cgroup Same under Lubuntu. I found reports of similar problems via Google, all of which point to Snap, but I don't see or understand a proper solution. How do you use x2go with this problem? Greeting, Olaf

Problems with X2Go locking windows clipboard
by David C. Partridge 31 Jan '25

31 Jan '25

I recently upgraded an LUbuntu 20.04 system with X2Go installed to LUbuntu 22.04. As part of that process, the X2Go server components got updated to 4.1.0.6-0~2023081 I don't know what version it was previously but it was at least 3 years ago that it was installed. Since then whenever I copy text in (e.g.) a bash terminal session on Linux system I am connected to, the Windows clipboard appears to get locked and I can't copy stuff from a Windows application to the clipboard. It either doesn't get copied or worse, the last text from the Linux system that was copied appears in the Windows clipboard. The X2Go Client on Windows is unchanged (4.1.2.2) Is there any fix for this? Thanks David

Cant resume sessions X2Go + PostgreSQL
by Jooris Mettler 06 Jan '25

06 Jan '25

Hi there, I have a severe issue with x2go. There are 4 Servers (ubuntu 20.04) and a single PostgresQL Database running in Docker on a 5th device. It all started after noticing that some users couldn´t resume sessions, this seemed to spread to all users over several months. Restarting the Server fixed the issue short term, but is not an option to do frequently. Some things I noticed: 1. the users ~/.x2go gets filled up with references to /tmp/.x2go-<user>/<session-id> and ofc /tmp gets populated accordingly. Once a Session is closed, everything persists there. Since /tmp will be cleaned on a restart, I would assume some job would also delete these old references going to nowhere, but it does not happen. 2. While I can click the "suspend" button on the client, the session will not change on the server. Even manually running x2gosuspend-session <session-id> on the server via e.g. ssh and checking the status via x2golistsessions returns |R| for the session in question. 3. when suspending a session, I would expect it to create a folder in ~/.cache/sessions/xfce4-session-<servername:number>. It does not. If I try to connect to a still running (server side, but from client side "suspended") session, it will either prompt a wrong credentials error or continue normally, except no window will ever show up. In x2goclient debug mode It will not whow the reappaering "searching proxy for window: <session-id>" but will simply stop after: "x2go-DEBUG-../src/sshmasterconnection.cpp:2065> Executing remote: "bash -l -c 'echo "X2GODATABEGIN:cb3d39c0-4759-419a-a1da-7c6681410a50"; export PATH="/usr/local/bin:/usr/bin:/bin";export TERM="dumb"; x2goresume-session <session-id> 800x600 lan nopack us auto 1 both no; echo "X2GODATAEND:cb3d39c0-4759-419a-a1da-7c6681410a50";'" x2go-DEBUG-../src/sshmasterconnection.cpp:2082> New exec channel created. x2go-DEBUG-../src/onmainwindow.cpp:10344> Resolved localhost. x2go-DEBUG-../src/onmainwindow.cpp:10372> Port already in use: 6002 x2go-DEBUG-../src/onmainwindow.cpp:10602> X.Org Server started on DISPLAY 2. x2go-DEBUG-../src/onmainwindow.cpp:10824> All helper servers for Windows are started." No window shows, I can not resume a session. I can run terminate and it will not show up anymore on the list on the client side or using x2golistsessions, but it will still be there in the database. 4. Having a look at the database, I can see thousands of entries. Most of those sessions dont exist anymore, no user can connect to them, they are not shown using x2golistsessions. I thought I could simply delete them like shown in the wiki (https://wiki.x2go.org/doku.php/wiki:advanced:multi-node:x2goserver-pgsql?s[…) but it does not work. Trying to delete any entry will always result in DELETE 0. I hope someone has an Idea or that this is helpful in any way to debug and improve x2go. Best, Jooris

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 Windows client crashes with Putty Pageant with long RSA 4096 keys
by Gerhard Wiesinger 20 Dec '24

20 Dec '24

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? Version: - X2Go Client 4.1.2.3-ba65703-kdrclient-a3134d6 - according to the logs: ssh_connect: libssh 0.9.2 (c) 2003-2019 Aris Adamantiadis, Andreas Schneider and libssh contributors. Distributed under the LGPL, please refer to COPYING file for information about your rights, using threading threads_pthread - Server: (not relevant but version is: x2goserver-4.1.0.6-4.fc41.x86_64) Thnx.

x2gomountdirs fails on Debian Stable (x2goclient 4.1.2.2)
by edv＠dgb-bwt.de 17 Dec '24

17 Dec '24

Dear All, first of all: great software, we (a small educational organisation for trade union members) have been working with it for years. TL;DR: shared folders do not work, when I use the GUI to mount a share directory ~/media/disk/SHARE-NAME remains empty. Our Setup: * x2goserver on a computer behind a rounter with portforwarding and dyndns * x2goclient on a computer behind another router * both debian stable The connection from x2goclient to x2goserver works (I mean: I get my remote desktop and work there), but when I want to use/mount a shared folder, nothing happens. I mean: If I want to access a folder on the x2goclient via the x2go function “shared folders” from the x2goserver, the directory ~/media/disk/SHARE-NAME remains empty. When I trigger the release in the GUI of x2goclient, the logs say: on x2goclient ----------- Nov 06 00:00:02 x2go /usr/bin/x2gomountdirs[295124]: insertion of shared folder into session DB has been successful Nov 06 00:00:02 x2go /usr/bin/x2gomountdirs[295124]: SSH key file has arrived: /home/serveruser/.x2go/ssh/key.cicFLi Nov 06 00:00:02 x2go /usr/bin/x2gomountdirs[295124]: SSH host key has arrived: /home/serveruser/.x2go/ssh/key.cicFLi.ident Nov 06 00:00:02 x2go /usr/bin/x2gomountdirs[295124]: executing: timeout 30 sshfs -o modules=iconv,from_code=UTF-8,to_code=UTF-8 -o idmap=user,uid=`id -u`,gid=`id -g`,default_permissions,ServerAliveInterval=300,IdentityFile=/home/serveruser/.x2go/ssh/key.cicFLi,UserKnownHostsFile=/home/serveruser/.x2go/ssh/key.cicFLi.ident "clientuser"@127.0.0.1:"/home/clientuser/Desktop" "/tmp/.x2go-serveruser/media/disk/_home_clientuser_Desktop" -p 53200 Nov 06 00:00:03 x2go /usr/bin/x2gomountdirs[295124]: WARNING: mounting of /home/clientuser/Desktop failed ----------- on x2goserver ----------- Nov 06 00:00:02 kweezy sshd[244865]: error: kex_exchange_identification: Connection closed by remote host Nov 06 00:00:02 kweezy sshd[244865]: Connection closed by 127.0.0.1 port 52856 Nov 06 00:00:03 kweezy sshd[244871]: Failed password for clientuser from 127.0.0.1 port 52872 ssh2 Nov 06 00:00:03 kweezy sshd[244871]: Failed password for clientuser from 127.0.0.1 port 52872 ssh2 Nov 06 00:00:03 kweezy sshd[244871]: Connection closed by authenticating user clientuser 127.0.0.1 port 52872 [preauth] ----------- Terminal-Output of 'x2goclient --debug --libssh-debug' on x2goclient ----------- x2go-DEBUG-../src/sshmasterconnection.cpp:2121> EOF on channel 0x7f7ed4064930; SshProcess object: 4 x2go-DEBUG-../src/sshmasterconnection.cpp:2222> EOF sent. x2go-DEBUG-../src/sshmasterconnection.cpp:2224> Channel closed. x2go-DEBUG-../src/sshmasterconnection.cpp:2165> EOF on channel 0x7f7ed40586c0; SshProcess object: 17 x2go-DEBUG-../src/sshmasterconnection.cpp:2222> EOF sent. x2go-DEBUG-../src/sshmasterconnection.cpp:2224> Channel closed. x2go-DEBUG-../src/sshprocess.cpp:532> SSH finished: raw output (stdout): "X2GODATABEGIN:d396bc9c-fce4-420a-9c3a-b405fddfc022\ndirs:/home/clientuser/Desktop__REVERSESSH_PORT__53200\nssh port:53200\nHost:127.0.0.1\nUser:clientuser\ninserted, timeout 30 sshfs -o modules=iconv,from_code=UTF-8,to_code=UTF-8 -o idmap=user,uid=`id -u`,gid=`id -g`,default_permissions,ServerAliveInterval=300,IdentityFile=/home/serveruser/.x2go/ssh/key.cicFLi,UserKnownHostsFile=/home/serveruser/.x2go/ssh/key.cicFLi.ident \"clientuser\"@127.0.0.1:\"/home/clientuser/Desktop\" \"/tmp/.x2go-serveruser/media/disk/_home_clientuser_Desktop\" -p 53200\nX2GODATAEND:d396bc9c-fce4-420a-9c3a-b405fddfc022\n" x2go-DEBUG-../src/sshprocess.cpp:543> SSH finished: true - "dirs:/home/clientuser/Desktop__REVERSESSH_PORT__53200\nssh port:53200\nHost:127.0.0.1\nUser:clientuser\ninserted, timeout 30 sshfs -o modules=iconv,from_code=UTF-8,to_code=UTF-8 -o idmap=user,uid=`id -u`,gid=`id -g`,default_permissions,ServerAliveInterval=300,IdentityFile=/home/serveruser/.x2go/ssh/key.cicFLi,UserKnownHostsFile=/home/serveruser/.x2go/ssh/key.cicFLi.ident \"clientuser\"@127.0.0.1:\"/home/clientuser/Desktop\" \"/tmp/.x2go-serveruser/media/disk/_home_clientuser_Desktop\" -p 53200\n" (17). x2go-DEBUG-../src/onmainwindow.cpp:8895> Post-cleanup for startX2goMount triggered. x2go-DEBUG-../src/onmainwindow.cpp:8920> Deactivating public key from "/home/clientuser/.x2go/ssh/gen/key.cicFLi.pub" again. ----------- I then tried to reach the client from the x2goserver via SSH through the SSH tunnel that was set up: ----------- serveruser@x2goserver:~$ ssh clientuser(a)127.0.0.1 -p 53200 -i /home/serveruser/.x2go/ssh/key.cicFLi Warning: Identity file /home/serveruser/.x2go/ssh/key.WEIIYY not accessible: No such file or directory. clientuser(a)127.0.0.1's password: ----------- This generates a message in the x2goclient log -- so the tunnel back to the client has been set up, but the temporary SSH key is no longer available.

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. 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 one 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.

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).

x2go with Yubico Authenticator - FIDO2 / WebAuthn
by x2go_org.only676＠silomails.com 28 Nov '24

28 Nov '24

Hi All I have a question using Yubico Authenticator through an x2go session. I apologize for asking this question multiple times but I finally found the mailing list, so I'm posting the question here If the question had already been answered, in the libera chat, could the answer pls be reposted here? I'm interested in using FIDO2/ WebAuthn (with Yubico Authenticator in a remote machine (machine B), accessing the Yubikey plugged into the local machine (machine A) My Yubico Authenticator on machine B can access FIDO2 / WebAuthn of the Yubikey plugged into machine A, by using usbip, and if I am logged into the machine B's terminal directly But if I use x2go to remote from A to B, trying to use FIDO2 / WebAuthn on the remoted machine B to machine A's yubikey (connected using usbip) stops working So because it works successfully with usbip without the x2go session, but stops working with the x2go session connected, it seems like there's something about the x2go session to cause the FIDO2 / WebAuthn to stop working. Thoughts? best regards
