Re: [X2Go-Dev] [X2Go-User] win32 x2go client not resuming
by Will Wagner 06 Mar '15

06 Mar '15

I get an ssl error when I try to use 3.99.2.2. I redirected stderr and ran the app. This is the output: x2go-INFO-1> "Starting x2goclient..." x2go-WARNING-1> "Can't load translator: :/x2goclient_en_gb" x2go-WARNING-2> "Can't load translator: :/qt_en_GB" x2go-INFO-3> "Started x2goclient." x2go-INFO-8> "Starting connection to server: 172.20.0.2:22" Object::connect: No such slot ONMainWindow::slotTunnelOk() Looking at the source code it appears that the sshconnection comes up and calls the slot slotTunnelOk(int). That function checks if winServersReady and if not tries to call itself again in 100mS by calling QTimer::singleShot ( 100, this, SLOT ( slotTunnelOk() ) ); The int argument is missing in slotTunnelOk and so it fails and the app then hangs. Does that sound like a reasonable analysis? Rather than trying to build the code myself could someone doa build with that change and I'm happy to test it.

"features/cleanup" (and "bugfix/osx") branch in x2goclient.git
by Mihai Moldovan 06 Mar '15

06 Mar '15

Hi all For the last couple of weeks, I've been working on the OS X side of X2Go Client, as some of you may or may not have noticed. Part of that work was a restructuring of the x2goclient.git repository. I started forking master to features/cleanup, gradually moved files around into new sub-directories and adapted all files affected by these moves. Additionally, macbuild.sh has been severely improved. It now supports multiple environment variables. A help message can be queried by (./)macbuild.sh -h or --help from any OS and will not be included here. x2goclient is now built in the client_build sub-directory to not pollute the main directory or overwrite the Makefile. List of changes: - moved .cpp/.h/.ui sources to src/ - moved png, svg and icons to res/ - moved all translation files to res/i18n/ - moved OS X build related files to res/macbuild/ - removed config_mac.sh (macbuild.sh supersedes it) - aforementioned macbuild.sh changes - change "legacy" resource URL's (":/icons/...", ":/png/...", ":/svg/...") to their ":/img/..." counterparts - added transparent wrapper to x2goutils.cpp for wrapping "legacy" resource URL's to their new locations for backwards-compatibility with old session config files - fixed some compiler warnings (mostly unused variables/parameters) - fixed *some* QMessageBox::<function> calls. There still are a lot of plain incorrect calls left. - typo, grammar and outdated information fixes A visual representation of these changes can be seen when comparing http://code.x2go.org/gitweb?p=x2goclient.git;a=tree and http://code.x2go.org/gitweb?p=x2goclient.git;a=tree;h=refs/heads/feature/cl… The bugfix/osx branch is currently equivalent to features/cleanup. Subsequent OS X fixes will be published on bugfix/osx. features/cleanup is scheduled to be merged into master (and thus become the X2Go Client 4.0.4.0 base) either shortly after this report, or after the upcoming X2Go Developer Meeting at the beginning of March. What is YOUR opinion? Best, Mihai

Bug#803: Further debugging
by Florian Wicke - Hetzner Online AG 05 Mar '15

05 Mar '15

My production environment is debian/jessie but the same problematic behaviour is present in fedora 21 (x2goserver from default repo) and ubuntu 14.10 (ppa:x2go/stable) I don't think it's something directly related to x2go but you might have way more insight in the process of the session management and can provide me with more hints to where the problem could actually be. -- Best Regards, Florian Wicke Hetzner Online AG Industriestr. 25 91710 Gunzenhausen Tel: +49 9831 505-0 Fax: +49 9831 505-3 florian.wicke(a)hetzner.de http://www.hetzner.de Registergericht Ansbach, HRB 3204 Vorstandsvorsitzender: Dipl.

Bug#789: Kerberos 5 auth. reset putty sessions list
by Jozsef Kozo 05 Mar '15

05 Mar '15

Package: X2Go Client Version: 4.0.3.1( Qt-4.8.6 ) OS: Windows 8.1 Enterprise x64 Dear Dev. Team, I switched on "Kerberos 5 (GSSAPI) authentication" on X2Go client and all my saved Putty sessions are gone. So Saved session list is empty. I tried to recover from registry but can't. You can reproduce like this: 1. Save a session to Putty 2. Set Kerberos 5 (GSSAPI) authentication 3. Connect to X2Go server Any idea how can i recover my list? Best, Jozsef Kozo

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#789: I reproduced it
by Michael DePaulo 05 Mar '15

05 Mar '15

I reproduced this bug on my system: X2Go Client for Windows 4.0.3.2-20150301-debug Windows 10 64-bit (build 9926 with latest patches) I've CC'd the developer who added Windows Kerberos support, Alex. I've attached the "Sessions" registry key before and after. The test session I created, uss-phoenix, was clearly deleted. HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions\uss-phoenix\ However, there is no indication in the debug log (attached) that the Sessions key or its subkey was touched. I'll take a look at the x2goclient source code to figure out what is going on. -Mike#2

Bug#803: Numlock-state resets on first keypress after resume/start
by Florian Wicke - Hetzner Online AG 04 Mar '15

04 Mar '15

Package: x2goserver Version: 4.0.1.18-0x2go1+git20141006.949+jessie.main.1 Unfortunately i am NOT able to "synchronize" the local numlock status to the client session in any way or even CHANGE the numlock status of the usersession. Clients running as thinclients with "x2gothinclient-displaymanager" from heuler and everything is up2date with the "heuler" branch. Desktop is XFCE but the same issue appears with KDE or LXDE. Numlock-state saving is disabled - but should not be executed on resume as far as i understand - just on starting a new session. Even replacing "x2gosetkeyboard" with an empty "exit 0"-script does not change this behavier (my first guess was the setxkbd resetting the numlock state on keypress). Any ideas how i can debug this further? Steps to reproduce: 1. turn numlock off and verify with 'numlockx status' in the user session 2. start terminal with 'numlockx status'-loop like: while :; do sleep 1; numockx status; done 3. have a post-resume.d-script present with 'numlockx on'-command (with correct DISPLAY set) 4. suspend session (5. turn local numlock on) 6. resume session 7. see 'numlockx status' transists from "off" to "on" as executed from the post-resume.d-script but now the unexpected problem: 8. press ANY key on the keyboard 9. see 'numlockx status' transists to "off" again no matter what your local keyboard is set. Time between #7 and #8 does not matter - first keypress after resume resets numlock.

Bug#789: Kerberos 5 auth. reset putty sessions list
by Earl Tom 04 Mar '15

04 Mar '15

I think this is a duplicate of bug #625. There's a snippet of code attached to that bug that looks suspicious. I think it's trying to delete one session but ends up deleting them all. This hits me, too, so it would be nice to have it fixed. My workaround is that I've exported a .reg file of the sessions and import that after starting x2goclient. Thanks, -- Earl
