Bug#1010: Issue on OS X
by Thomas Watson 16 May '16

16 May '16

I have the exact problem with an Ubuntu 14.04 server and OSX 10.11 client. I set single application mode to launch /usr/bin/xterm. Moving the window incurs a 3 or 4 second delay before the application is responsive again. For the app I want to use (MATLAB), this makes single app mode completely useless for me as well. It pops up lots of small windows as GUI elements and these also have a slightly faster 1 or 2 second delay.

Bug#1036: add support for Mobile-OTP (MOTP) tokens
by Tor Perkins 16 May '16

16 May '16

Package: x2goclient Version: 4.0.5.2 Tags: patch Hello, There is very nice OTP (One Time Password) algorithm called "Mobile-OTP" (MOTP). Here is a link for more information: http://motp.sourceforge.net/ This small patch extends x2goclient's OTP support to accommodate MOTP. The patch adds a new string ("passcode:") to challenge_auth_code_prompts_[]. It also adds some comments that indicates the source of the various prompt strings in that array. MOTP is a very nice algorithm that is worthy of support for several reasons. It is "free" and "open" and does not rely on a third party infrastructure to operate. It is a Time-based One Time Password (TOTP) algorithm (like OATH can be), with a distinguishing advantage; it does 2FA ("2 Factor Authentication") innately. That is because it requires a 4 digit PIN to be entered every time it is used. The PIN is not stored in the "token" (i.e. smartphone), so a stolen phone does an attacker no good... It is well established and popular. There are many versions of the "token" available (much more than just IOS and Android apps). It is supported by several "backend" systems (like LinOTP). Please refer to the "Links" section on the project page for many more examples... Thanks for your consideration! X2Go rocks! - Tor

Bug#1034: Fix a segfault in x2goclient with OpenBSD
by Denis Fondras 14 May '16

14 May '16

Package: x2goclient Version: 4.0.5.1 Tag: patch When compiling X2Go client on OpenBSD5.9/amd64, x2goclient will segfault in SshMasterConnection::channelLoop(). The culprit is the declaration of buffer[] inside the code of this function, moving it outside of channelLoop() fixes the segfault.

Bug#994: x2goclient x server crashes when launching gitk or git-gui
by Benjamin Shadwick 07 May '16

07 May '16

I can confirm this issue occurs on Windows 10 x64 client with x2goclient v4.0.5.0 and Ubuntu MATE 14.04 LTS x64 x2goserver host. I'm currently testing it in "published applications" mode, in which I started a MATE terminal and then ran 'git gui' from the terminal window. VcXsrv crashes with a "VcXsrv windows xserver (X2Go/Arctica Builds) has stopped working" dialog in Windows. All published application windows then close, while x2goclient continues to run. Resuming the session appears to restore all windows, including the git gui window.

Bug#1025: Still various unstranslated GUI elements
by Mike Gabriel 05 May '16

05 May '16

Package: x2goclient Severity: minor Version: 4.0.5.1 Hi all, I still see various untranslated string in X2Go Client 4.0.5.1: (1) The little down-arrow on session cards: "Session preferences..." "Create session icon on desktop" (2) Main menu: Session -> "Session Management", "Create session icon on desktop" (3) Session Prefernces dialog window: Session Tab [x] Try autologin ... Input/Output Tab (.) Auto-detect keyboard settings Sharing [x] Use port forwarding... About X2Go Client -> Description text is in English (4) possibly more... I checked this with LANG=de_DE.UTF-8 and LANG=es_ES.UTF-8. The issues occur in both languages, so I presume the causes are in the original code somewhere.

Fwd: x2goserver on arm64 platform
by Mihai Moldovan 04 May '16

04 May '16

I have enabled arm64, armhf and ppc64el builds in both repositories, added the Yakkety series to all packages and (hopefully) built everything for arm64, armhf and ppc64el within both PPAs. There were some failures, most notably x2goclient in the nightly repo for Trusty for arm64. x2gomatebindings is in dependency wait mode for arm64 and armhf for Trusty and arm64 for Precise. Everything else seems to have worked fine so far, at least compilation-wise. Mihai

Re: [X2Go-Dev] Firefox 45.0-2 and 46.0-2 on Archlinux crash when used with x2go
by U. M. Goon 04 May '16

Hi, I had the same problem, and I believe it is caused by the recent move to GTK3. You can confirm that by playing around with the gtk3-demo app. Just run it for a minute and randomly click/run stuff in there. As a workaround, there is a firefox-gtk2 package in the AUR (takes some hours to compile, but the -bin version is buggy). Here is a stack trace of the gtk3-demo crashing with the same error, unfortunately I don't have debug builds, but XIGetClientPointer doesn't work the way gtk3 calls it somehow. (gtk3-demo:6305): Gdk-ERROR **: The program 'gtk3-demo' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRequest (invalid request code or no such operation)'. (Details: serial 21589 error_code 1 request_code 131 (XInputExtension) minor_code 45) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Thread 1 "gtk3-demo" received signal SIGTRAP, Trace/breakpoint trap. 0x00007ffff55517eb in g_logv () from /usr/lib/libglib-2.0.so.0 (gdb) bt #0 0x00007ffff55517eb in g_logv () from /usr/lib/libglib-2.0.so.0 #1 0x00007ffff555195f in g_log () from /usr/lib/libglib-2.0.so.0 #2 0x00007ffff7276ad8 in ??
