Bug#625: Enabling Kerberos5 (GSSAPI) Auth deletes saved Putty Sessions
by Sterzinger, Benedikt 05 Mar '15

05 Mar '15

Package: x2goclient Version: 4.0.2.1 After establishing to a x2go server with GSSAPI auth enabled, all the sessions saved in putty are gone. We found this snippet in the source code (sshprocess.cpp): void SshProcess::rmPuttyReg(QString uuidStr) { QSettings st("HKEY_CURRENT_USER\\Software\\SimonTatham\\PuTTY\\Sessions", QSettings::NativeFormat); st.remove(uuidStr); st.sync(); } ... void SshProcess::slotSshProcFinished(int exitCode, QProcess::ExitStatus exitStatus) { normalExited=false; if (exitCode==0 && exitStatus==QProcess::NormalExit) normalExited=true; #ifdef DEBUG x2goDebug<<"ssh process exit code :"<<exitStatus; #endif #ifdef Q_OS_WIN if(masterCon->useKerberos()) { rmPuttyReg(procUuid); } #endif slotChannelClosed(this,procUuid); } Is this necessary? *********** Hinweis zur Datensicherheit Die Datenübertragung über das Internet erfolgt derzeit im Wesentlichen ungesichert.

Bug#510: ctrl-alt-f crashes x2go windows 7 client
by Rob MacLachlan 03 Mar '15

03 Mar '15

Package: x2go I'm running x2go win32 client, version 4.0.2.0. Similar behavior happened in 4.0.1.2. This with remote host running x2goversion x2goagent: 3.5.0.21 x2goserver: 4.0.1.13 x2goserver-extensions: 4.0.1.13 x2goserver-fmbindings: 4.0.1.13 x2goserver-xsession: 4.0.1.13 # Springdale linux 6.5 uname -a inux lov3.int.autonlab.org 2.6.32-431.17.1.el6.x86_64 #1 SMP Wed May 7 21:28:34 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux Whenever I type ctrl-alt-f, bad things happen. I understand this is supposed to switch full screen mode in the default shortcuts, but it doesn't actually successfully create a working full-screen setup (no keystrokes are recognized), and anyway the reason I'm typing ctrl-alt-f is to do "forward form" in EMACS. I would be fine with just changing the default shortcuts, but I haven't been able to figure out how to do that either. The wiki instructions on changing the shortcuts don't seem to work (maybe obsolete file location?). Rob

Bug#658: session connect with Python X2Go freezes if gevent 0.13.6 is used
by Mike Gabriel 31 Jan '15

31 Jan '15

Package: python-x2go Sevrity: important Hi Pavel, Jan, TL;DR; for the bug tracker... Python X2Go 0.5.0.x freezes during X2GoControlSession.connect() when used with gevent 0.13.6. With Python 0.4.0.x no such freeze could be observed.

A Ubuntu precise system with python-gevent (I obviously did not provide a newer gevent version for precise in our X2Go PPA on Launchpad). I will join in to get this narrowed down.

Bug#108: Missing fonts in X application
by Stephane Mutz 25 Jan '15

25 Jan '15

Package: x2goclient Setup: X2go server on Ubuntu 12.10, client on Win7 Issue: One of our CAD application displays unreadable text. When trying to select another font, only one is available. xlsfonts also reports only a few fonts. The application works fine locallyor when using a Linux X2go client and xlsfonts shows a long list of fonts. How to solve: Install the 'font' directory from the VcXsrv mainline package. After that, the application shows readable text and provides a large selection of alternative fonts. I think it would be good to bring the Windows and Linux client closer by shipping a more complete VcXsrv with it or at least offering the option.

Bug#697: Nightly x2goserver crashes the x2go windows client on connect
by Jasmin Lévesque 12 Jan '15

12 Jan '15

Package: x2goserver Version: git master @HEAD When using the latest x2goserver and connecting with x2go client on Windows, the client crashes on connect. I tried the latest nightly build and my own compiled from HEAD (to solve issue #676), with 2 different clients (v4.0.3.0 & v4.0.2.0) the behavior is the same. I also tried not to use a full fledged KDE session, even with a single application "xterm" the app crashes. I tried a combination of client-side configs (no sound, no clipboard, no printing etc..) with the same results. I created a server with a fresh CentOS install to isolate any possible server-side configuration issue, the behavior is the same again. I see that the server creates the ssh connection, the client get to acknowledge the new server ssh key, the client crashes a few seconds later. There is no log entries generated in the %userprofile%/.x2go or in the /home/$USER/.x2go/ folder. If you can think about any other test case, i'm willing to try them and provide feedback. Thanks, Jasmin Levesque Senior System Analyst Vlan! Technologie

Package: x2goserver Version: 4.0.1.9 I am running Lubuntu trusty on an armhf server. I tried to install x2goserver as described on http://wiki.x2go.org/doku.php/wiki:repositories:ubuntu I found at least the following packages are missing: x2goserver nxagent Could you, please, upload the missing packages.

Bug#712: x2goserver: armhf unfulfilled dependency
by Heinrich Schuchardt 09 Jan '15

09 Jan '15

Package: x2goserver Version: 4.0.1.18 x2goserver depends on libdbd-pg-perl. This package is only available for architectures amd64 and i386. Please, change debian/control such that the dependency is recommended only on architectures amd64 and i386 Background: x2goserver can run on SQLite. No need to force a dependency on PostgreSQL. Better check while running if the Perl module can be loaded: # imports into current package BEGIN { unless (eval "use $mod") { warn "couldn't load $mod: $@"; } } Best regards Heinrich Schuchardt

Bug#616: Finally managed to record the issue "on tape"
by Stefan Baur 09 Jan '15

09 Jan '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, please have a look at http://youtu.be/5RJ2kwrgeXI This is X2Go Client 4.0.3.0 showing the 5-second startup delay (hourglass cursor). Note that the on-access virus scanner was disabled for this recording, as can be seen on the lower right (red icon), so we can that one rule out as the cause of the problem. Things I learned, trying to capture this: - - The effect does not occur inside a VMware Workstation VM. So you neither see it nor will you be able to record it there. - - The effect does occur on real hardware as well as on a Linux-LVM accessed via RDP. - - It is impossible to record the effect using CamStudio. While you can witness the effect occurring live, the recorded video will only show the regular mouse arrow. - - Recording the effect was possible using Microsoft Expression Encoder. $DEITY knows why. @Alex: This effect occurs since you tried to introduce the "reaper" process (even before you split x2goclient.exe into half with the helper, I think). It was not present before that.

Bug#666: point out that x2gobroker is not a security feature
by Stefan Baur 09 Jan '15

09 Jan '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Package: x2gobroker Severity: wishlist Please add a prominent note to x2gobroker's man page that it is *not* intended as a security feature - a user can still launch x2goclient without the broker parameter and set it to run any executable the user has exec permission for on the server. As always, group membership and file permissions *MUST* (MUST as defined in RFC2119 https://www.ietf.org/rfc/rfc2119.txt) be used to limit a user's access to executables on the server. - -Stefan - -- 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 v2.0.22 (MingW32) iQEcBAEBAgAGBQJUXAlfAAoJEG7d9BjNvlEZ+eAH/06sGKiAbYx5Lzf5ehEZcM/R 5lumXu0SOVHsCIen/KRAHP+MQ+wvGngNawo0PZsJBZyhvHQ/SeUMrotR3MSPFB3S ZDYvznt4LEfBbKbm4uabBmFOiSndFaFlyZzwt95z/SrAdaLidphUXlkTI0Mu5UOI qVQbZWtBUNmEF+I1MalAvpGCZ+JK3BpSg88Y7XDqZvQfTcUUBxr9MGWBxKL5CHlK Lt6jIZzXdxX+RWK7SmA5zYpUCG7yZcR6EzSnq7U1cDqW3XNG/QvddvS4IL04/u/U 068Tl/gHhKr3vquDjyMjXnuP8TbBFuTmDb6qbJeyY+UrC/n5kmXIlFRrBkZPnKM= =ej1y -----END PGP SIGNATURE-----
