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!

Error: Aborting session with 'Unable to open display 'nx/nx,options=/tmp/.x2go-user/C-user-50-1634698056_stDGNOME_dp24/options:50''. Session: Aborting session at 'Tue Oct 19 22:48:16 2021'. 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. Many thanks in advance, Shea I was trying to follow: https://wiki.x2go.org/doku.php/wiki:advanced:x2gohtmlclient on a Ubuntu 20.04.03 LTS (then later a Debian 11) minimal desktop and I have distilled the wiki instructions to: # =============== # Ubuntu: Install Software # =============== sudo apt install -y \ fcgiwrap \ g++ \ git \ libcgi-pm-perl \ libencode-perl \ libexpect-perl \ libfile-touch-perl \ libjson-perl \ make \ minify \ nginx-full \ qt5-default \ qt5-qmake \ websockify \ x2goserver \ ;

nx-libs updated in X2Go nightly repository (aka X2Go heuler)
by Mike Gabriel 18 Oct '21

18 Oct '21

Hi all, I have just updated X2Go's nx-libs (nxagent/nxproxy) version in X2Go's nightly builds repositories (aka X2Go heuler).

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.

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.

In 1967, a court in West Berlin overturned the 1933 verdict, and posthumously changed Van der Lubbe's sentence to eight years in prison. -- "Reichstag fire" on Wikipedia.
