X2Go: The Gathering 2021 AKA "Over 9000!" (2021-12-03 - 2021-12-04) will be an entirely virtual event

Dear $ALL, As stated in the subject line, X2Go: The Gathering 2021 - AKA "Over 9000!" - will be an entirely virtual event and will take place from Friday afternoon, 2021-12-03, to Sunday afternoon/evening, 2021-12-05. If you're wondering what the “Over 9000!” is about, take a look at <https://en.wikipedia.org/wiki/It%27s_Over_9000!> and at <https://experience.arcgis.com/experience/478220a4c454480e823b17327b2bf1d4>, especially the box titled “COVID-19-Fälle” (active Covid-19 cases), which is way over 9000. Under normal conditions, X2Go: The Gathering would be the annual event where users, admins, and developers (including the i18n volunteers) of X2Go, as well as members from the Arctica project and the orca e.V. nonprofit meet face to face, to discuss current X2Go-related issues, fix open bugs, and have a good time getting to know each other. Sadly, due to the ongoing Covid-19 pandemic, this year's X2Go: The Gathering will have to remain entirely virtual. Due to various reasons, we were unable to schedule the event earlier in the year, where Covid-19 infection numbers were lower and where meeting outside or keeping the windows open all day might have worked, so we're stuck with this late event date, which sadly coincides with the fourth Covid-19 wave here in Germany. This means we will be meeting via Jitsi and we will be live-streaming the event via YouTube. Links to the streams will be posted on <http://wiki.x2go.org/doku.php/events:x2go-gathering-2021> each day before the stream begins. You can join in any time, even on short notice, no sign-up required. We will be updating the Wiki page <http://wiki.x2go.org/doku.php/events:x2go-gathering-2021> as more information becomes available - especially the schedule, which is currently still in the works. We plan to release (at least) three new features for X2Go at or at least shortly after this year's X2Go: The Gathering, namely: - the HTML5 client - server-side X2Go-KDrive support, and - X2Go support in Remmina. The former two are currently already available via nightly builds, but we intend to declare them stable and turn them into a proper release. The latter should become available with the next Remmina release. Also, we intend to present the current state of X2Go-TCE on the Raspberry Pi. If time permits (and the individuals required for this are available for it), we will also attempt to move our bugtracker and git to our own gitlab instance (at least for new bugs). As this year's event is an entirely virtual event, there is not really a need for event sponsorships. However, if you're a company that had planned to sponsor the event, we'd appreciate it if you'd redirect the money to some paid work on X2Go instead. A list of companies/individuals available for this can be found here: <https://wiki.x2go.org/doku.php/doc:professional-support> If you're not sure what to sponsor - while the features already mentioned above are ready to be included in a stable release, they could still use some more love and affection. For example: - The HTML5 and Remmina clients don't support file and printer sharing yet - The HTML5 client also lacks sound support - The HTML5 client only works with KDrive, not "classic" X2Go-NX (to be honest, NX inside HTML5 doesn't really make sense since we are about to release KDrive as stable, but if you feel you have a good reason for it, let us know ...) - Remmina only works with "classic" X2Go-NX, not KDrive, and only on a client that still supports X11 (even though Remmina in general also works on a Wayland-only client) -> KDrive support would require a shared library for KDrive, either written in GTK or with more low level rendering toolskits (e.g. Glib-2.0 and Cairo, etc.). - KDrive probably needs some more work on the Windows (and possibly macOS) Client side. - X2Go-TCE on the Pi, while functional in general, still has some untested areas and is a little rough around the edges. - Also, we have been contacted once again regarding USB forwarding support in X2Go, so anyone interested in co-sponsoring this feature should speak up or at least contact me off-list - maybe we can get a co-sponsoring going, lowering the cost for all parties involved. And of course, you can also make donations, either in general or specifically earmarked for X2Go, via orca e.V. The entire schedule, save for the time and date of the orca e.V. meeting on Sunday, is still in a state of flux. We may move some presentations to a Saturday slot, depending on the availability of the speakers involved. If you would like to present something, please contact me via E-Mail (<mailto:X2Go-ML-1@baur-itcs.de>) and let me know the title of your presentation/talk, the expected duration and the times you would be available. Of course, you can also pre-record your presentation/talk if you want, but you will have to upload it to YouTube yourself and let us know the link (it may be unlisted, but must not be marked "private"). Sincerely, Stefan Baur, "X2Go: The Gathering" event organizer PS: Please heed the "reply-to" when replying, and make sure your reply gets sent only to <mailto:x2go-ml-1@baur-itcs.de>, as this message is sent to multiple X2Go mailing lists at once (and it is likely you are not subscribed to all of them, so your replies would clog up the moderation queue for the others). -- 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

Urgent: Increase disk on VM/Container
by Melroy van den Berg 01 Dec '21

01 Dec '21

Hi, Could somebody increase the disk on the VM/Container of GitLab (188.40.111.169). It causes a lot of IO performance issues. The '/' disk mount is now 100% full. Regards, Melroy van den Berg melroy89(a)pm.me

Bug#1571: Terminate session button selected by default on timeout
by Joe Dight 24 Nov '21

24 Nov '21

Package: x2goclient Version: 4.1.2.2 Tag: patch If the connection drops a dialog box asks to terminate the session or continue, with terminate selected by default. Continue should be selected by default. This doesn't seem to be intended (the constructor is called incorrectly), and the attached patch fixes it for me.

Hi tl;dr: x2gohtmlclient sends websocket input that nxagent rejects, then aborts on Debian 11 and Ubuntu 20.04.03; e.g. websockify records " var VNC_frame_data = [ '}3}6ba1f53e7eb3536232eeff332bd49336', '}3}\x07\x00\x00\x00\x00\x05\x98\x03\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 " nxagent reports Loop: WARNING!

I saw https://lists.x2go.org/pipermail/x2go-dev/2021-June/013764.html so I tried both Debian 11 and Ubuntu 20.04.03 but same failure on both. I'm new to x2go and the x2goclient works great so maybe this is an x2gohtmlclient et. al. issue? Perhaps this is a known issue or a misconfiguration on my part with a quick and easy answer.

vmlinuz, initrd and squashfs for netboot.xyz
by x2go-dev＠jugra.de 28 Sep '21

28 Sep '21

Hello together, after last messages on x2go-user mailing list I plan to try to integrate live-build-x2go into https://netboot.xyz/ I need place where we can place kernel, initrd and squashfs ~200M , so that it should not run to timeouts on another side of the earth. Maybe it's rational to make extra subdomain for it like boot.x2go.org and maybe mirror it to CDN. What do you think about it? Where would be the best hosting place for it? As a benefit x2go-users can use linux x2goclient if a main system is not running (or just for tests), but they have internet access and can boot floppy, cd, usb or just bootloader entry with netboot.xyz.lkrn (ipxe) or maybe netboot setup with tftp onside. On very modern systems it can be UEFI entry for httpboot. Best Regards, Juri Grabowski

Bug#1427: Update Tumbleweed packages for Perl 5.30
by Tristan Miller 28 Sep '21

28 Sep '21

Package: x2goserver Version: 4.1.0.4 Tags: rpm-packages Various openSUSE Tumbleweed packages for the X2Go server are built in such a way that they require Perl 5.28.1. However, Tumbleweed no longer distributes that version of Perl; it now distributes only Perl 5.30.1. This means that it is impossible to install these X2Go server packages on the most recent release of Tumbleweed, and for Tumbleweed systems where those X2Go server packages were already installed, it is impossible to upgrade Tumbleweed without removing the X2Go server: $ sudo zypper dup [sudo] password for root: Loading repository data... Reading installed packages... Warning: You are about to do a distribution upgrade with all enabled repositories. Make sure these repositories are compatible before you continue. See 'man zypper' for more information about this command. Computing distribution upgrade... 9 Problems: Problem: x2goserver-common-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Problem: perl-5.28.1-3.4.x86_64 requires perl-base = 5.28.1, but this requirement cannot be provided Problem: perl-X2Go-Server-DB-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Problem: perl-X2Go-Server-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Problem: perl-X2Go-Log-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Problem: x2goserver-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Simply telling zypper to keep the obsolete packages doesn't work as this ends up in a rabbit-hole of seemingly irresolvable dependency issues.

Please consider adding packages for the current version of the OS, openSUSE Leap 15.3, which was released on 2021-06-02. I've filed this bug against x2goclient but the same request applies to x2goserver and ancillary x2go packages.

Updated XFCE wiki section: "No workarounds required"
by Melroy van den Berg 23 Sep '21

23 Sep '21

Hi, I just want to let you all know I updated the wiki section of "Always compatible - No workarounds required" for XFCE (spoiler, a workaround is required): https://wiki.x2go.org/doku.php/doc:de-compat#always_compatible_and_no_worka… So, XFCE actually needs a workaround now due to a compositor issue with either XFCE or X2Go, see ticket in xfwm4 project: https://gitlab.xfce.org/xfce/xfwm4/-/issues/551 Wiki Diff: https://wiki.x2go.org/doku.php/doc:de-compat?do=diff&rev2%5B0%5D=1595856306… So you know :)...

Bug#1520: Proxy-Server - SSH - strong Cipher crash x2Go-Client
by Marian.Schwarcz＠dlr.de 20 Sep '21

20 Sep '21

Package: x2goClient Version: 4.1.2.2-2020.02.13 Host-System: Windows 10, und Windows Server 2012 R2 (German Language) Installations-Typ: Recommended (Default) *** Problem Description *** When using x2GoClient via jumpserver (as SSH-Proxy-Server), then is X2GoClient automatic closed (without any Information). Problem are the SSH-Strong-Ciphers, which are configured in SSHd on Jumpserver. Strong Ciphers => x2GoClient crashed. If default Ciphers => x2GoClient and connection works. *** X2GoClient - Configuration *** Sitzungsname: test Pfad: / Host: ziel-server Login: test_ye SSH-Port: 22 Proxy-Server für SSH-Verbindung verwenden SSH Host: jumpserver Port: 22 Gleiche Anmeldung wie für X2Go-Server Gleiches Kennwort wie für X2Go-Server XFCE *** Jumpserver Configuration) *** Jumpserver SSHd Config: /etc/ssh/sshd_config (CentOS 7) Ciphers aes128-ctr,aes192-ctr,aes256-ctr The ciphers are used for strong Encryption. Then access from x2GoClient via jumpserver cannot handle this. ------ When the Cipher-Restriction is not configured: Jumpserver SSHd Confg: (CentOS 7) #Ciphers aes128-ctr,aes192-ctr,aes256-ctr then the connection from x2GoClient via jumpserver to Destination X2Go-Server does work. I hope I provided all needed information for you. Let me know if this can be patched, or does our Company need to search for other solution. Thank you. Best regards, Marián Schwarcz

x2gokdrive: Move remote_init call into ddxProcessArgs function
by Mike Gabriel 01 Sep '21

01 Sep '21

Hi Alex, I looked into cmdline option parsing of x2gokdrive today. Reason was that I have a server where I set "-clipboard client" via a cmdline option. The x2gokdrive executable failed on that, because -clipboard is not a known option. What I found is that, other than in nxagent, in x2gokdrive the remote_init function is called via OsVendorInit, just when the session is about to start. In nxagent, the nxagentOption Rec (remoteVars in x2gokdrive is the equivalent) gets initialized earlier in ddxProcessArgs, this is a bit earlier. In X2Go, we have /etc/x2go/x2goagent.options. The file allows one to inject extra options into nxagent via server-side cmdline options. With Uli I recently discussed that the cmdline options should actually supercede the nx/nx options (so that X2Go-wise, site-admins can enforce certain agent features that cannot be overridden by X2Go Client client parameters). For nxagent, we are actually discussing a change in Args.c to make this possible. So, for x2gokdrive, I wonder if we could establish such a feature, as well: let cmdline options (set in /etc/x2go/x2goagent.options) override nx/nx options coming from X2Go Client and for this we would need to support setting remoteVars via cmdline options in ddxProcessArgs. For this, we would have to move the remoteVars init bit over into ddxProcessArgs (x2gokdriveinit.c, instead of x2gokdriveremote.c). I tried this locally, but failed, because whenever I referenced remoteVars from x2gokdriveinit.c the x2gokdrive ran into a segmentation fault. As you are much more familiar with the x2gokdrive code, is this something you could take a look at? For now, I have added a commit that adds more stub and compat cmdline options to x2gokdrive, also -clipboard.

Bug#1557: Windows client crashes when connecting to RHEL8
by Hans Peter Verne 27 Aug '21

27 Aug '21

Package: x2goclient Version: 4.1.2.2 Hello, devs! I'm afraid this is not a very precise bug report. Any assistance in how to investigate this is appreciated. We're running x2goclient 4.1.2.2 on Windows-10 machines, this has served us well up to now. With our new RedHat Enterprise Server 8.4 in production, we see the client crashing very often. When the client crashes, it does so shortly after trying to log in to a new or existing session. The clients "show details" window pane is activated, but the client dies before anything can be seen there. On the server, just these entries in the system logs appears: Aug 05 14:42:56 mimi.uio.no sshd[2421324]: Connection from 2001:700:100:4028:9462:e3c7:21c5:ec1c port 49763 on 2001:700:100:118::101 port 22 Aug 05 14:42:59 mimi.uio.no sshd[2421324]: Connection reset by 2001:700:100:4028:9462:e3c7:21c5:ec1c port 49763 [preauth] If I disable IPv6: Aug 05 14:45:30 mimi.uio.no sshd[2421601]: Connection from 193.157.161.44 port 57619 on 129.240.118.101 port 22 Aug 05 14:45:33 mimi.uio.no sshd[2421601]: Connection reset by 193.157.161.44 port 57619 [preauth] Note the absence of the "Fail password for ..." log entry. It looks like it never gets to even try authenticating. There is no problem logging in with putty from the same client machine, both with IPv6 and IPv4. Neither have I had this problem (at least not so frequent) with the Linux client. The server is running sshd and x2goserver from the RHEL8/EPEL repos, packages openssh-server-8.0p1-6 and x2goserver-4.1.0.3-9, respectively. I eventually tried to run sshd -ddd on the server and catch the output. The typescripts are attached (slightly edited): one where the client crashed; and one where it didn't (but couldn't authenticate, bad password). I'm no expert on ssh, but it seems like the difference appears after the key exchange ("KEX done"), when the instance that crashed never reaches the bit with userauth-request. I also tried "setenforce 0" on the server, i.e. disable SELinux, but the client still crashed. As it is, I can't clearly provide a procedure to reproduce the problem, as it doesn't always happen. If more information is required, or there are suggested steps to take, please let me know. Thanks in advance, and best regards, -- Hans Peter Verne -- IT-drift Geofag.

Bug#1561: bug of ssh daemon\s public host key
by guo jiawei 24 Aug '21

24 Aug '21

Package: X2GO Client Version: 4.1.2.2 My x2go client can’t work. It report an error that “SSH daemon failed to opean it’s public host key. You have enabled remote printing or file sharing. The features require a running and functioning SSH server on your computer.Pringting and file sharing will be disable for this session. Normally this should not happen as X2GOclient for windows ships its own internal SSH server and automatically generates the required keys.”. And it asks me to report a bug on //wiki.x2go.org/doku.php/wiki:bugs It says disabling remote Pringting or file sharing support in the session setting will get rid of this message.

Clean processes after x2goterminate-session
by Oleksandr Shneyder 19 Aug '21

19 Aug '21

Hello all, I realized, that sometimes (depends on distro and DE) after terminating session with x2goterminate-session some processes related to the X2Go session are not exiting. At the moment x2goterminate-session only terminates the agent process and we can have leftovers like x2goruncommand, dbus-run-session, etc. I think we should do some improvements in x2goterminate-session to clean this processes. Any ideas? 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.

Bug#1559: Evolution fails under X2Go but OK locally
by Roy Beaulieu 17 Aug '21

17 Aug '21

Package: Evolution Version: 3.36.5-0ubuntu1 Evolution fails to launch or even error under X2Go version 4.1.0.3-5 server. Works file locally. Server is simple Ubuntu 20.04 LTS with TASKSEL installed Xfce Desktop. When Evolution is executed in TERMINAL, error says: "Failed to initialize gtk+: Unable to initialize the Clutter backend: no available drivers found." I found this bug report from 2015 that says: “From version 3.30.5-1 Evolution in remote session x2go can be run without workaround mentioned below. It seems for me that the bug is closed.” https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=710828 Bug reporter in 2015 refers to your 2020 article of: https://wiki.x2go.org/doku.php/wiki:development:glx-xlib-workaround This workaround for getting GLX 1.4 working has lots of things I don’t understand as a new user. I don’t wish to damage a working system by trying things that may no longer be the solution just to get Evolution to work. If it's still required, I'll try my best but some steps look dated. Has this "Unable to initialize the Clutter backend" issue returned? Is "Workaround for getting GLX 1.4 working" still needed for programs such as Evolution? Thank you in advance, Roy

Failing resuming session with latest X2Go Server from nightly builds
by Oleksandr Shneyder 04 Aug '21

Hello guys, one of my customers reported that after update x2go server from 4.1.0.4-0x2go1.2~git20210627.1936+10.heuler.1 amd64 to 4.1.0.4-0x2go1.2~git20201228.1914+10.heuler.1 amd64 he not able to resume sessions anymore. I checked it on my system and I can confirm it. I figured out, that somehow x2goresume-session makes session option file empty (size = 0). @Mihai: I saw that you commited some changes in x2goresume-sessions between this two versions. Do you have idea what could go wrong here, before I'll start to debug it by myself? 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.

Pull request: add --nofork option to x2gocleansessions
by Andrew J. Hesford 02 Aug '21

02 Aug '21

Greetings, Following is a pull request against the 4.1.0.x branch that separates the no-fork behavior of x2gocleansessions from the debug output behavior. A new flag, `--nofork` (`-n-` for short) determined whether the program forks; `--debug` only controls the logging verbosity and also forces `$nofork=1` to preserve old behavior. Please let me know if anything should be changed. Thanks, Andrew Hesford The following changes since commit cabad60865be64de219b3b477ddaefa6aef1cf43: Continue development (2018-11-29 08:09:45 +0100) are available in the Git repository at: https://github.com/ahesford/x2goserver.git nofork for you to fetch changes up to 4587d918c138205c252316c007fab31b75b87061: Separate non-forking behavior from --debug into --nofork (2021-05-11 19:27:02 -0400) ---------------------------------------------------------------- Andrew J.

02 Aug '21

Package: x2goserver Version: 4.1.0.3 When I run x2goclient 4.1.2.2, on my Windows 10 64-bit machine, the following error appears: * Error: The remote NX proxy closed the connection.* * Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie* The x2goserver 4.1.0.3 and nxagent 3.5.99.26 is installed on a RHEL 8.2 64-bits workstation. On the RHEL 8.2 workstation, I tried to delete the x2go database and recreate it without effect: I also tried to run the x2goagent (see x2goagent.txt) thinking I got a clearer error, but the x2go windows opened correctly.

Bug#1554: matlab colors inverted in X2go client
by Anna Spiers 02 Aug '21

02 Aug '21

Package: x2goclient Version: 4.1.2.2 (Qt-4.8.7) When using Matlab on an Ubuntu linux server accessed through x2goclient, the Matlab window has inverted colors (e.g., background is black, text is various colors with different highlighted colors). I'm using x2go from a 2017 Macbook Pro with MacOS Catalina. I've recently found the matlab window inverts its colors when the x2goclient window is off-screen to the left, but when it's completely contained by my monitor window or slightly off-screen to the right, then the colors are normal. A similar problem happens on my colleague's 2020 Macbook Pro with MacOS Big Sur, but no matter how he configures the x2goclient window, his matlab screen still has inverted colors.

Bug#1553: x2goserver error: unknown operating system
by Henrik Schmidt 02 Aug '21

02 Aug '21

Package: x2goserver Version: 4.1.0.4 When starting a x2go session with the server running Opensuse Tumbleweed OS I expect to get a session. What I get is the error message:|"Unknown operating system, XSession startup not implemented!" I looked at the x2goserver source code and it checked for ||[ -f /etc/SUSE-brand ] || [ -f /etc/SuSE-release ] which both are absent. I did a 'touch ||/etc/SuSE-release|' on the server and x2go started working again. So there should be a better detection for Opensuse Tumbleweed.

Bug#1552: Bug: server clipboard settings overridden by client when session is closed and reconnected
by DANIEL PAVANAN 02 Aug '21

02 Aug '21

Package: x2goserver Version: 4.1.0.3 I ve encountered a bug in the server's clipboard setting. Please review the below detail and advise necessary solutions or kindly fix issues. *Problem -* server clipboard settings overridden by client when session is closed and reconnected with any change in session setting. *Steps to reproduce-* 1 edit /etc/x2go/x2goagent.options, added ... X2GO_NXAGENT_DEFAULT_OPTIONS+=" -clipboard client" 2 reloaded server, setup up client session setting and connected first time around it works as intended (from the client we could copy to server, but not from server to client) 3 now close the x2go client session window and change some setting in session preferences -> Input/ Output -> clipboard more (it could be server to client copy or bidirectional copy ) and connect the session again Now the server's clipboard setting is overridden by the clients clipboard setting and we can copy from server to client. Change in the session preferences can also be something different like change in compression method in connection tab *Expected behaviour* whatever the action from client side, when server setting for clipboard options is set, client's option should NOT override *Info * Client OS - linux mint mate 20 ulyana x2goclient version - 4.1.2.2-1 x2goclient session settings - [20210612224421681] applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL autologin=false clipboard=both command=MATE defsndport=true directrdp=false directrdpsettings= directxdmcp=false directxdmcpsettings= display=1 dpi=142 export= fstunnel=true fullscreen=false height=1080 host=<host name here> icon=:/img/icons/128x128/x2gosession.png iconvfrom=ISO8859-1 iconvto=UTF-8 kdrive=false key=/path/to/user/sshkey krbdelegation=false krblogin=false maxdim=false multidisp=false name=<session name here> pack=2m-jpeg print=false published=false quality=9 rdpclient=rdesktop rdpoptions= rdpport=3389 rdpserver= rootless=false setdpi=true sndport=4713 sound=true soundsystem=pulse soundtunnel=true speed=2 sshport=<ssh custom port no> sshproxyautologin=false sshproxyhost= sshproxykeyfile= sshproxykrblogin=false sshproxyport=22 sshproxysamepass=false sshproxysameuser=false sshproxytype=SSH sshproxyuser= startsoundsystem=true type=auto useiconv=false usekbd=true user=<remote user name here> usesshproxy=false width=1920 xdmcpclient=Xnest xdmcpserver=localhost xinerama=false server OS - ubuntu server 20.04 LTS x2goserver: 4.1.0.3 x2goserver-common: 4.1.0.3 x2goserver-extensions: 4.1.0.3 x2goserver-fmbindings: 4.1.0.3 x2goserver-printing: 4.1.0.3 x2goserver-x2goagent: 3.5.99.23 (not sure why this x2goagent version is out of sink with the others, how can I update this) x2goserver-xsession: 4.1.0.3 x2goagent options - (removed the comments ) X2GO_NXAGENT_DEFAULT_OPTIONS="" X2GO_NXAGENT_DEFAULT_OPTIONS+=" -extension GLX" X2GO_NXAGENT_DEFAULT_OPTIONS+=" -nolisten tcp" X2GO_NXAGENT_DEFAULT_OPTIONS+=" -clipboard client" X2GO_NXOPTIONS="" desktop environment installed mate installed with apt-get install ubuntu-mate-desktop other settings not changed Moreover the server version installed is from 2018 and its not in the same timeline as the client version which is from 2020.

Bug#913: Inaccurate scaling of dialog boxes and fonts for large DPI screen in Windows 10
by Alves-Foss, James (jimaf＠uidaho.edu) 02 Aug '21

02 Aug '21

Package: x2goclient for windows Version: 4.0.5.0 Downloaded new version of x2goclient for a new Dell Laptop. Screen resolution 3200x1800. OS Windows 10 (just checked, same problem on similar machine in Windows 8.1) When I open the main program, the fonts and windows do not scale well in the session selection boxes When I create a new session and try to open it, I can not see the list of open sessions to connect to. This appears to be a scaling issue for high DPI systems. I tried Windows 7, Windows 8 compatibility modes. I tries to disable display scaling on high DPI systems (see attached images)

Pull request: add --nofork option to x2gocleansessions
by Andrew J. Hesford 27 Jun '21

27 Jun '21

Greetings, Following is a pull request against the 4.1.0.x branch that separates the no-fork behavior of x2gocleansessions from the debug output behavior. A new flag, `--nofork` (`-n-` for short) determined whether the program forks; `--debug` only controls the logging verbosity and also forces `$nofork=1` to preserve old behavior. Please let me know if anything should be changed. Thanks, Andrew Hesford The following changes since commit cabad60865be64de219b3b477ddaefa6aef1cf43: Continue development (2018-11-29 08:09:45 +0100) are available in the Git repository at: https://github.com/ahesford/x2goserver.git nofork for you to fetch changes up to 4587d918c138205c252316c007fab31b75b87061: Separate non-forking behavior from --debug into --nofork (2021-05-11 19:27:02 -0400) ---------------------------------------------------------------- Andrew J.

Bug#1487: sftp-server is missing message (I do not need filetransfer)
by Zounp 24 Jun '21

24 Jun '21

Hello, This issue is still applicable. This is not a bug but a safety request. For my application I do not need folder sharing nor printing support. So I did not install: rdesktop, openssh-server nor openssh-sftp-server on the client computer Installing a server is a security risk. I do not want to install servers on my client computer (on which I am running x2goclient) So it is not a big issue but it is still annoying. So it would be so nice if the need for the sftp-server (folder sharing nor printing support) can be made optional via a setting for instance. Thanks for X2Go. Thanks. -- Met vriendelijke groet, Zounp

Hi Alex, On Mi 21 Apr 2021 22:43:53 CEST, Oleksandr Shneyder wrote: > https://wiki.x2go.org/doku.php/wiki:advanced:x2gohtmlclient I am currently trying to provide an out-of-the-box DEB installation of x2gohtmlclient. For this, I need to make some adjustments, mainly these are about wss: traffic becoming optional and defaulting everything to localhost with ws: protocol. Of course, in real world deployments, this needs to SSL'ified again. But I'd really love to provide DEBs that demo x2gohtmlclient out-of-the-box (and SSL certificates are not so much things that come out of the box). This all seems to work fine, only that I get a failure when x2goclient.min.js starts communicating with the x2gokdrive Xserver (via x2gowswrapper, via websockify). I think that my seen bug is caused by my websockify 0.9 which has the text data mode removed (compared to earlier versions). See: https://github.com/novnc/websockify/issues/365#issuecomment-432270758 As I am testing everything on Debian 11, I indeed have websockify 0.9 installed. Where did you test the whole stack of x2gohtmlclient, x2goclient.min.js, x2gowebrpc and x2gowswrapper on? Debian 10, maybe? My symptom in the browser is: - Logon works - X2Go KDrive sessions starts in the background (processes come up, desktop is resumable via native X2Go Client later on) - X2Go Logo appears in the placeholder area in the webbrowser - X2Go session strings is shown at the top of the session window in the browser - and then, the session is immediately closed again. The (error) message(s) I get in the browser console while this happens are/is these/this: ``` WS Open Event {isTrusted: true, type: "open", target: WebSocket, currentTarget: WebSocket, eventPhase: 2, …} x2goclient.min.js:208 Sending geometry event: ArrayBuffer(41) Uint32Array(5) [7, 60294400, 0, 0, 0] Uint16Array(5) [7, 0, 1280, 920, 0] x2goclient.min.js:204 Sending client Version and OS: ArrayBuffer(41)byteLength: (...)__proto__: ArrayBuffer[[Int8Array]]: Int8Array(41)[[Uint8Array]]: Uint8Array(41)[[ArrayBufferByteLength]]: 41[[ArrayBufferData]]: "0x0fc800a0c030" Uint32Array(5) [10, 196612, 0, 0, 0]0: 101: 1966122: 03: 04: 0buffer: (...)byteLength: (...)byteOffset: (...)length: (...)Symbol(Symbol.toStringTag): (...)__proto__: TypedArray Uint16Array(5) [10, 0, 4, 3, 0]0: 101: 02: 43: 34: 0buffer: (...)byteLength: (...)byteOffset: (...)length: (...)Symbol(Symbol.toStringTag): (...)__proto__: TypedArray x2goclient.min.js:265 WS Close CloseEvent {isTrusted: true, wasClean: true, code: 1003, reason: "Unsupported: Text frames are not supported", type: "close", …} ``` Before I dig any deeper, could you try your test setups with websockify 0.9 and report back if you see a similar error popping up or not?

Bug#581: VirtualBox Clipboard Sharing does not work when accessing the host over X2Go
by Michael DePaulo 18 Jun '21

18 Jun '21

Package: nx-libs Version: 3.5.0.27 Severity: normal If you run a VirtualBox VM with its display running under X2Go, the VM's clipboard sharing fails to work in either direction. You cannot copy and paste text between the VM and an app running under X2Go server, nor can you copy and paste text between the VM and an app running on the X2Go Client system. (I believe VirtualBox VMs use SDL to interact with the X server, which in this case is nxagent. This differs from the VirtualBox GUI, which is written in QT.) Specifically, when the X sesssion starts on the guest, a VirtualBox-provided script for X calls "VBoxClient --clipboard" to start the clipboard service. The service runs as the user logged into the guest. However, this service fails to stay running, and thus the clipboard sharing does not work. If you launch the VirtualBox VM on the local X.org X server, the guest's clipboard service stays running and clipboard sharing works. You can also launch the VM in RDP headless mode from x2go (so the VM does not render its display to any nxagent). In this use case, the clipboard service stays running and clipboard sharing works. The strange part is that the configuration of the host affects the behavior of the guest. It makes sense though because it's a bug in the guest's code to integrate with the host. Also, when you do call "VBoxClient --clipboard", it returns 0. And if you call it after the X11 session has already started, the problem still occurs. In x2goclient, I tried turning on and off the following setting, but it had no effect: Options -> Settings -> X-Server settings -> do not use primary clipboard My theory is that this is a bug in nx-libs, and that the bug is probably related to nx-libs being forked from such an old X.org codebase. It is worth looking into whether other SDL apps have clipboard trouble with X2Go on Ubuntu 14.04. (It's also worth testing an older release of Ubuntu as the host OS, since it would have an older release of SDL.)

X2Go Client Nightly builds for debian bullseye
by Oleksandr Shneyder 16 Jun '21

16 Jun '21

Hi guys, I just checked the Jenkins and I could see that there are some issues building the X2Go Client heuler packages for bullseye. Looks like the problem is in qt4 build dependencies, which is not available in bullseye anymore. I don't want to get involved in the packaging process, but I think it's very important to have the nightly builds working for debian testing. What do you think about it? 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.

Bug#1548: Acknowledgement (Copy & Paste images with x2goserver and x2goserver-x2gokdrive)
by Miguel Quero 26 May '21

26 May '21

Of course, I think my company was starting a project to help the development of some opensource projects. I am from the technical side and I don't have visibility but I have just escalated it in case they tell me something. I don't think it's a big deal, we are a small company, but something will surely help. Best regards.

Bug#1548: Copy & Paste images with x2goserver and x2goserver-x2gokdrive
by Miguel Quero 24 May '21

24 May '21

Package: x2goclient Version: 4.1.2.3 Hi, First of all congratulate you for your great work with x2go. We have been using x2go for years in research and reporting environments. The problem we have is that usually in these environments the copy and paste of images is very common. Currently we overcome this problem with the option to share folders but we would like to make the environment more agile by allowing to copy and paste images from the client to the server. After investigating the options we have found the following: 1) If the connection is made through the new kdrive, the clipboard shares images correctly. For example: * Client side: xclip -selection clip -t image/jpg -i hades.jpeg * X2go Kdrive Server side: a simple ctrl-v on a document opened on the server and the image is copied perfectly. * Problems: The problem is kdrive itself that for example for Spanish language neither accents nor many symbols work: (á ^ ä ç à ...). 2) With normal x2go: * Client side: xclip -selection clip -t image/jpg -i hades.jpeg * SSH normal contextion: The clipboard is shared ok xclip -selection clipboard -t TARGETS -o TARGETS image/jpg * X2go Server side: Nothing appear in clipboard :( Any ideas?

Bug#1547: x2go client does not work on Ubuntu 20.04 LTS
by Dirk Kleinhesselink 18 May '21

18 May '21

Package: x2goclient Version: 4.1.2.2-1 The x2goclient does not start the remote desktop for a client on ubuntu 20.04 LTS. This worked fine on Ubuntu 18.04LTS. The client launch says connecting and after a short pause changes to finished but the remote desktop never appears. I am running Ubuntu 20.04 LTS, the current kernel is: 5.4.0-73-generic I've tried different local desktops - MATE, gnome, tried disabling wayland, always the same result.

x2go client help
by Silvia Luescher Folk 13 May '21

13 May '21

Hi, I am having an issue on a Mac Os 11.3 with the x2go client: The issue is that right after restarting my Computer I have no problem connecting to my remote server. But after I stop that session and restarting it later I get the eternal “connecting" status. The only way to fix this is by restarting my computer. My guess is I have to kill some process, but it is not obvious to me which one. Could you help me troubleshoot this? Thank you, Silvia

Bug#1546: Feature-request: Customizable kerberos ticket cache location
by Florian Oppermann 12 May '21

12 May '21

Package: x2goclient Version: 4.1.2.2 Current situation: Authentication via kerberos puts the credential cache into $HOME/.x2go/C-$sessionId/krb5cc. In our system this is problematic as access to $HOME requires a valid kerberos ticket, i.e. once the ticket expires it can’t be renewed from within the X2Go session because access to the ticket cache is denied. For normal logins, the krb5cc is located at /tmp which prevents this problem. I’d appreciate an option to set the location where to put the ticket cache. I believe the current behaviour comes from src/onmainwindow.cpp:7332 where the location is more or less hard-coded. My suggestion would be to add either a configuration option in the GUI or at least a command line switch to change this location. I’m not familiar enough with the code to provide a patch but I think it should be not too difficult. Thanks for all your great work! :-)

Bug#1545: x2goserver: separate
by Jonathan Kirszling 10 May '21

10 May '21

Package: x2goserver Version: 4.1.0.3 I'm packaging x2goclient and x2goserver for voidlinux distro. Voidlinux doesn't use systemd as init, but runit. We need to be able to write a runit service script for x2gocleansessions. x2gocleansessions forks when it is run. Using --debug doesn't fork but print a lot of informations, catched by the service. Could you separate --no-fork from --debug please ? More details here : https://github.com/void-linux/void-packages/issues/30781 Thanks by advance, Have a nice day.

Bug#1544: x2goclient not connecting [with a provisional fix]
by Andrey Malyshev 07 May '21

07 May '21

Package: x2goclient Version: 4.1.2.2 x2goclient stoppped connecting to a working x2go server after some update of the client on both Linux and Mac boxes. Provisional fix - The offending line is "Port 22" in the localhost section of the ~/.ssh/config file on the client side. Commenting out the line solves the problem on both Linux and Mac boxes. It seems that some parser (no idea if it is the x2goclient's or the nxproxy's one) is doing some strange thing and gets confused, as the error message has nothing to do to the port line. A permanent fix would be appreciated. Below are the relevant part of the output from x2goclient --debug and the content of the ~/.ssh/config file with an offending Port line in the localhost section: x2goclient --debug: x2go-INFO-1> "Starting X2Go Client 4.1.2.2..." ... x2go-DEBUG-../src/onmainwindow.cpp:6142> "Starting NX proxy, command: nxproxy -S nx/nx,options=/home/andrei/.x2go/S-andrei-50-1620380095_stRTERMINAL_dp24/options:50" ... x2go-DEBUG-../src/onmainwindow.cpp:6618> Proxy wrote on stderr: "\nNXPROXY - Version 3.5.99.26\n\n...." ... x2go-DEBUG-../src/sshmasterconnection.cpp:1994> Forwarding parameters: from remote ("localhost":33106) to local ("localhost":60552) x2go-DEBUG-../src/sshmasterconnection.cpp:2028> Temporary session port after config file parse: 22 x2go-DEBUG-../src/sshmasterconnection.cpp:2032> Temporary session host after config file parse: 127.0.0.1 x2go-DEBUG-../src/sshmasterconnection.cpp:2059> New channel forwarded. ... x2go-DEBUG-../src/onmainwindow.cpp:6618> Proxy wrote on stderr: "Loop: PANIC!
