Bug#850: Better Mouse Pointer Handling for Shadow Sessions
by Stefan Baur 30 Jan '24

30 Jan '24

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 package: nxagent severity: wishlist - From a usability/user experience standpoint, it would be nice if: a) one could see the remote mouse pointr on one's own screen when running a shadowed session b) the person sitting at the remote screen could see one's own mouse pointer when running a shadowed session c) there was a way to "latch" the pointers together, so that only one pointer is visible on the screen, and each pointing device input, no matter if made locally or remote, moves this single pointer - -- 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 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJVMlAhAAoJEG7d9BjNvlEZdREH/2AfJ4ciAu8rSmDZjrRetbNw 3KjOxBFzW+fAvc9LAN+8dwWQbSFts4NkF7ycYTZR+RyUHwwoUvL5Th/MDAE/Xau/ Li+556zgypyYkB1N253Lv4yEfxybvSmolsM5FPsI0mi5WDVVjtbMjwYCNxQrdrc2 yoAoSahsuc8FCUiwTHpbMMbgXor3hQt77pxHswQ2+rV/v0i+/345uKxRoOQ2XnQl ZVOT5hSRlBs7U+G6zwfGdFDSiPhN0uOqMLUgAiPPOLzMlYAWDyPBfTYhhSf2yGCD WcbyMp1pPFoiTgn9yelKulR25I/gxDT0NduC6ImJNC26jOZ5lMhTnLqrvbkTyM8= =CNAu -----END PGP SIGNATURE-----

Bug#117: Make Cinnamon selectable
by Mirco Schmidt 30 Jan '24

30 Jan '24

Package: x2goserver Severity: wishlist Hi hi, I tried to start cinnamon with this command: /usr/bin/gnome-session --session cinnamon2d but it fail's! If I set it to: /etc/X11/Xsession it should start the last session which is cinnamon but come's up with a XFCE session... [12:18pm] [12:33pm]sunweaver:mirco, the command launched by X2Go does not accept cmdline parms. Write a shell wrapper on the server and execute that. Note: your wrapper must be in $PATH [12:33pm]mirco:THX made a wrapper like this and placed it in /usr/local/bin: #!/bin/bash /usr/bin/gnome-session --session cinnamon2d [12:37pm]mirco:sadly I end up with a blank screen, beatified by the default debian Desktop background… Which is also my personal one! Thank's in advance Mirco

Bug#849: No Mouse Pointer in a Fullscreen Shadow Session on MS Windows

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 package: nxagent While it is to be expected that you can't see the mouse pointer of the user you're trying to assist, not seeing your own mouse pointer is really quite annoying.

Bug#846: Terminating a Fullscreen Shadow Session on Linux is Clumsy
by Stefan Baur 30 Jan '24

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'.

Info: Screen [0] resized to geometry [1680x1050] fullscreen [1]. Session: Suspending session at 'Wed Mar 25 21:30:39 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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 package: x2goclient severity: wishlist Hi, this is actually a sub-bug of http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=738. I am fling it as a separate bug because I believe this particular part of Bug 738 can be resolved rather quickly. Currently, X2GoClient offers the free choice of X-Servers to be used with it, but ships with VcXsrv as default and has some "sane" default settings configured for it, too, so X2GoClient works out of the box. Whoever wishes to deviate from that path, is, however, free to do so - X2GoClient has an option to specify a custom X-Server of the user's choice. I would like to take a similar approach for printing. At present, no default PDF viewer is shipped with X2GoClient, and the user has to fiddle with whichever PDF viewer they choose to get the parameters right. SumatraPDF is a free (F/LOSS) PDF viewer that offers a portable version, i.e. it is a single, self-contained executable that doesn't require any installation. It also supports a wide range of command line parameters so it is ideal for scripted background use (like "open PDF, print to default printer, close application"). Quoting from http://www.sumatrapdfreader.org/manual.html: > Printing related cmd-line arguments: -print-to-default $file.pdf > prints a PDF file on a default printer -print-to $printer_name > $file.pdf prints a PDF on a given printer -print-dialog $file.pdf > opens a PDF file and shows a print dialog to select printer and > printing options -exit-on-print when -print-to-default or -print-to > is used, will exit after printing So, basically, "-exit-on-print -print-to-default" is all we'd need for basic functionality. If we want to do "enumPrinters" within X2GoClient, "-exit-on-print -print-to $printer" will also already work. If we want to leave printer selection to SumatraPDF, "-print-dialog" has to be used, and we'd probably have to submit a patch to the SumatraPDF project that "-exit-on-print" be made to work with "-print-dialog" as well, as the current description seems to indicate that this is not the case. Thus, I would ask that some helpful soul steps up and please a) includes SumatraPDF's standalone executable in the Windows X2GoClient package b) adds the proper code to X2GoClient so client-side printing defaults to using SumatraPDF in the X2Go program directory unless the user has created a custom configuration. The rationale for this bug is that adding this feature would increase usability of X2GoClient just as shipping a default X-Server does.

Bug#778: affected by CVE 2015-0235: Stop using gethosbyname()
by Mike Gabriel 25 Jan '24

25 Jan '24

Package: src:nx-libs Severity: important The NX source code uses gethostbyname() at several locations and is potentially affected by CVE 2015-0235 (GHOST security issue in glibc). We should move towards using getaddrinfo() asap.

Bug#694: CUPS 1.7.x remounts /tmp and breaks cups-x2go
by Mike Gabriel 25 Jan '24

25 Jan '24

Package: cups-x2go Severity: important The workaround provided below can be applied to x2goprint from x2goserver-printing package. But my gut feelings tell me, we need to review cups-x2go. Maybe this bug gets reassigned to x2goserver-printing later, if my gut feelings get proven wrong. Mike ----- Weitergeleitete Nachricht von Роман <inpos(a)yandex.ru> ----- Datum: Mon, 01 Dec 2014 10:59:36 +0300 Von: Роман <inpos(a)yandex.ru> Betreff: [X2Go-User] X2Go Linux Server. Virtual print issue workaround An: x2go-user(a)lists.x2go.org For those who can't print to redirected printer here my workaround. On X2Go Server do following (by root): ---------------------------------------------- cd /usr/bin mv x2goprint x2goprint.orig cat << EOF > x2goprint #!/bin/bash umount /tmp x2goprint.orig $@ EOF chmod a+x x2goprint ----------------------------------------------- The problem is that CUPS remounts /tmp during print process. Therefore temporary x2go directories have become unavailable.

Bug#854: Ubuntu 14.04: xinerama broken
by Ulrich Sibiller 22 Jan '24

22 Jan '24

Package: x2goclient, nx-x11-common Version: 4.0.3.2-0~800~ubuntu14.04.1 As far as I know opening an x2go session from a display that uses xinerama should do the following on the server side: - create a xinerama.conf with the xinerama setting on the client side - set NX_XINERAMA_CONF in the envrionment - extend the LD_LIBRARY_PATH to point to the nx xinerama lib. When I open an x2go session to my local machine (the same where the x2goclient is running) this does not work for several reasons: 1. /usr/lib/nx/X11/Xinerama/libXinerama.so.1 points to the i386 version of the lib which is not existing on my 64 bit machine. dpkg -S shows that this is coming from the package nx-x11-common. So obviously this is broken. 2. After fixing issue 1 by linking to the 64bit version it still does not work. This is because for Ubuntu there is only x2goclient 4.0.3 but you need 4.0.4 for xinerama... So could someone please update the Ubuntu repo? The xinerama feature is enabled for the session as well as for x2goclient (--xinerama). I am using ubuntu 14.04 with these x2go packages. These are the most current packages the repos provide and all oft Thema have been freshly installed yesterday. libnx-x11 2:3.5.0.29-0~505~ubuntu14.04.1 (does not contain any files) libnx-x11-6:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xcomposite1:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xdamage1:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xdmcp6:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xext6:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xfixes3:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xinerama1:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xpm4:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xrandr2:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xrender1:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 libnx-xtst6:amd64 2:3.5.0.31-0~605~ubuntu14.04.1 nx-x11-common 2:3.5.0.31-0~605~ubuntu14.04.1 nxagent 2:3.5.0.31-0~605~ubuntu14.04.1 nxproxy 2:3.5.0.31-0~605~ubuntu14.04.1 x2goagent 2:3.5.0.31-0~605~ubuntu14.04.1 x2goclient 4.0.3.2-0~800~ubuntu14.04.1 x2godesktopsharing 3.1.1.2-0~170~ubuntu14.04.1 x2goserver 4.0.1.19-0~1064~ubuntu14.04.1 x2goserver-common 4.1.0.0-0~1257~ubuntu14.04.1 x2goserver-extensions 4.0.1.19-0~1064~ubuntu14.04.1 x2goserver-xsession 4.0.1.19-0~1064~ubuntu14.04.1 x2gothinclient 1.1.0.2-0~469~ubuntu14.04.1 x2gothinclientmanagement 1.1.0.2-0~469~ubuntu14.04.1

Bug#970: lists.x2go.org domain lacks SPF record.
by Nable 22 Jan '24

22 Jan '24

Package: lists.x2go.org Severity: wishlist Dear maintainers, All messages that were sent from IPv6 address of freya.das-netzwerkteam.de are classified by Gmail (and possibly by other mail providers) as unwanted and unconditionally fall into "Spam" folder. Judging from message headers Gmail is also unsure about messages from its IPv4 address but acts more permissive. I always use "Not Spam" button for such false-positives but gmail still insists that something is wrong with such messages. I've noticed this problem about a year ago and now it became annoying enough to finally file a bug. I don't know the exact reason but it looks like the problem may hide in the absence of SPF record [1] for lists.x2go.org as this is the only suspicious thing in mail headers. Either way, usage of SPF is considered to be a good practice nowadays and a lot of companies deploy it. 1. https://en.wikipedia.org/wiki/Sender_Policy_Framework Cheers, Nable

Bug#878: gnome-terminal 3.16 fails to start
by Michael DePaulo 19 Jan '24

19 Jan '24

Package: nx-libs Version: 3.5.0.31 Severity: normal Server OS: Fedora 22 64-bit with latest updates (F22 is still in beta, but will be released any day now) x2goserver 4.0.1.19-3.fc22 (Fedora's package) x2goserver-xsession 4.0.1.19-3.fc22 (Fedora's package) nxagent 3.5.0.31-1.fc22 (Fedora's package) x2goagent 3.5.0.31-1.fc22 (Fedora's package) I've tried multiple different clients (on both Linux and Windows), so the client details presumably do not matter. The problem is that gnome-terminal is failing to launch. I have only tried a single application session. The output from `journalctl --user` (the equivalent of ~/.xsession-x2go-errors) is attached. This line stands out: org.a11y.atspi.Registry[24951]: Xlib: extension "XEVIE" missing on display ":50". However, XEvIE was removed from X.org in 2008: http://cgit.freedesktop.org/xorg/xserver/commit/?id=f4036f6ace5f770f0fe6a6e… http://freedesktop.org/wiki/Software/XEvIE/
