Bug#554: Disable local screensaver when x2go session is in fullscreen mode
by Reinhard Tartler 30 Jan '24

30 Jan '24

Package: nxproxy Severity: serious I noticed that the when nxproxy is in fullscreen mode, it (by design) captures all keyboard strokes. This is in general great because this way all keyboard shortcuts on the remote work. However, the local screen saver might still kick in and require a password. Because the nxproxy captures all input, a less carefull user might enter his local password into the current application that is running in the x2go session. When the remote application happens to be a chat application, entering your password might have serious security implications. I think a fullscreen nxproxy is a good reason to inhibit the local screensaver. -- regards, Reinhard

Bug#740: Ship a default, small-footprint, F/LOSS PDF viewer with x2goclient
by Stefan Baur 30 Jan '24

30 Jan '24

-----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.

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#795: pyhoca-gui leaves debug log outside rootdir in portable mode
by Milan Knížek 15 Jan '24

15 Jan '24

Package: pyhoca-gui Version: 0.5.0.4 It would be nice if the debug log file is stored inside the --sessions-rootdir so that files are kept within the "portable" definitions. ATM, the log files is stored within User's home dir in temporary folder (e.g. AppData\Roaming\pyhoca-gui\PyHoca-GUI.1516.log). Affected OS: Windows 7

Bug#748: configure broker settings via settings dialog box
by Mike Gabriel 15 Jan '24

It does not look very hard though, the PortableApps framework basically wraps around your app. http://portableapps.com/development http://portableapps.com/development/portableapps.com_format
