Subject: X2Go Client for Windows with libssh-0.5.x: cannot connect to hpn-enabled SSH servers

Date: Tue, 2 Sep 2014 18:31:49 +0200

[Message part 1 (text/plain, inline)]

Package: x2goclient
Version: some future release

Hi,

I'd like to request an update of libssh to version 0.6.x for the
Windows build of the X2Go Client software.
The current Windows builds which are shipped with libssh-0.5.5 have a
connection problem with hpn-enabled openssh servers [1].
We at Gentoo already faced the same problem a while ago [2].

The problem looks like this:
After a successful login with libssh-0.5.x to the hpn-enabled
openssh server the connection just hangs. There's no further data being
transferred from or to the server. This results in the X2Go Client to
hang as well.
After upgrading libssh to version 0.6.x the problem disappears.

Alex,

Do you have time to try to build libssh 0.6.3 like you did for 0.5.5?
If not, I'll try to do so over the next week or 2.

Like before, you need to incorporate the pageant patch:
http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=448
However, it does not apply cleanly. Many of the hunks fail. You are
much better at C programming than I am.

The 2 other patches (libssh-0.5.x-accept-forward.patch &
libssh-0.5.x-unblock.patch) have been upstreamed.

Subject: The patch, and upstreaming it

Date: Sat, 6 Sep 2014 21:57:32 -0400

The changelog mentions the work that I and my friend (Mike Frederick)
did on the Pageant patch to port it from libssh-0.5.x to libssh-0.6.3.

The libssh-0.6.3 version of the patch is here:
http://code.x2go.org/releases/source/libssh-modified-by-x2go-project/implement-support-for-putty-s-pageant-0.6.3-de62963.patch

I will try to upstream it. It was rough around the edges previously,
and it still is. We will probably have to revise it in order to get it
upstreamed. Hence why I put the git commit hash in the patch name;
it's the way of denoting the exact patch version.

The source code is here:
http://code.x2go.org/releases/source/libssh-modified-by-x2go-project/libssh-0.6.3-de62963-pageant-support.src.zip

And the binary + headers are in a .zip here:
http://code.x2go.org/releases/binary-win32/3rd-party/libssh-modified-by-x2go-project/libssh-0.6.3-de62963-pageant-support-mingw4.4.0.zip

I'd say yes. I presume without linking against zlib, SSH compression  
support won't be available via libssh. But I am just guessing.

With Python X2Go, I have disabled all compression features in  
Paramiko/SSH, because the compression should rather take place (and  
does) in NX. So dropping compression in SSH brings some server-side  
relaxation on the CPU, I hope. I did not do any benchmarking on this,  
though. With Telekinesis/mTelePlayer the subjective impression is that  
it speeds up things on large videos.

Greets,
Mike

X2Go Component: src:x2goclient
Version: 4.0.3.0-0x2go1
Status: RELEASE
Date: Tue, 21 Oct 2014 12:38:56 +0200
Fixes: 108 159 253 258 336 474 522 525 566 568 571 580 587 590 597 603 607 608 609 612 636
Changes: 
 x2goclient (4.0.3.0-0x2go1) RELEASED; urgency=low
 .
   [ Mike Gabriel ]
   * New upstream release (4.0.3.0):
     - Disallow server-side users to override X2Go Server commands via
       ~/bin (or similar). (Fixes: #336).
     - Avoid unitialised variables on early calls of ONMainWindow::closeEvent()
       or ONMainWindow::closeClient(). (Fixes: #253).
     - Update translation files. Add empty Portuguese translation. Update
       qt_<lang>.qm files from Debian unstable as of today.
     - Update German translation file (after session folder feature got added).
     - Makefile.man2html: Test if man2html exists. If not, don't fail.
     - Honor exports (client-side shared folders) from broker session profiles.
       Thanks to Ming Song for providing a patch for this (Fixes: 612).
   * debian/control:
     + Add B-D: apache2-dev. On squeeze / lucid builds, this is a superfluous
       B-D, but for later Debian/Ubuntu versions, this smoothes the installation
       of the x2goplugin-provide bin:package.
     + Update B-D: apache2-dev | libc6-dev. The apache2-dev package does not
       exist on all Debian/Ubuntu versions.
   * x2goclient.spec:
     + Adapt to building for openSUSE/SLES.
     + openSUSE: Make Qt4 Linguist tools available for Makefile.
     + Upgrade versioned BR for libssh-devel (0.6.3 or patched 0.5.5).
     + The libqt4-linguist split off happened in openSUSE 13.1.
     + Add x2goclient-rpmlintrc file.
     + In openSUSE, it is openldap2-devel, in Fedora/RHEL it is openldap-devel.
     + In openSUSE, openssh is openssh (not openssh-clients / openssh-server).
 .
   [ Oleksandr Shneyder ]
   * New upstream release (4.0.3.0):
     - Fix running x2goclient without arguments on Windows. (Fixes: #522).
     - Save proxy output in $HOME/S-$SESSION-ID/session.log if debugging is
       enabled.
     - Fork x2goclient on windows and terminate child processes if X2Go Client
       crashed. (Fixes: #159).
     - Add "clipboard" parameter to session profile and to command line options.
       (Fixes: #258).
     - Replace qCritical() with printError() by argument parsing.
     - Update translation files.
     - Update russian translation.
     - Update string "&Clipboard Mode" and translate in russian translation file.
     - Grammar fix in russian translation.
     - Add x2gohelper to start X2Go Client on Windows and clean child processes
       if X2Go Client crashes. (Fixes: #525).
     - On Windows rename x2goclient.exe to x2goclient-mainprocess.exe and
       x2gohelper.exe to x2goclient.exe.
     - Start x2gohelper from X2Go Client. Revert name changing of X2Go Client and
       x2gohelper.
     - Add Makefile for x2gohelper.
     - Add support for sessions folders.
     - Add folder explorer: a GUI to manage of session subfolders.
     - Support for sessions subfolders in sessionmanagedialog.

     - Remove deprecated workaround in wapi.cpp.
     - Save folder icons Base64 coded. Save icons under General\icon_<PATH>.
       (Fixes: #580).
     - Fix placing sessions folders in broker mode.
     - Fix onmainwindow.cpp after 76ae96781f1d2d5754ee4751539d5de47f1d0297.

 .
   [ Mike DePaulo ]
   * New upstream release (4.0.3.0):
     - Make X2Go Client aware of the Cinnamon (CINNAMON) desktop environment.
       (Fixes: #571)
     - Make X2Go Client aware of the Trinity (TRINITY) desktop environment.
       (Fixes: #609)
     - Make X2Go Client aware of the Openbox (OPENBOX) window manager.
       (Fixes: #607)
     - Make X2Go Client aware of the IceWM (ICEWM) window manager.
       (Fixes: #608)
     - Windows: Fix not being able to add the server to the known_hosts file when
       the username has non-English characters. (Fixes: #566)
       (NOTE: This fix only works when the non-English characters are in the same
       language as the Windows "system locale" AKA "Language for non-Unicode
       programs." Bug #611 was written for fixing the issue for languages other
       than the system locale.)
       Thanks George Trakatelis (uom.edu.gr) for submitting part of this fix.
     - Windows: Install VcXsrv "misc" fonts by default, and make all 4 font
       groups optional: misc, 75dpi, 100dpi and others (Fixes: #108)
       Note: The fact that all the fonts are included makes the installer about
       30MB larger.
     - Windows: Bundle new version of VcXsrv: 1.15.2.1-xp+vc2013+x2go1
       This new version is based on upstream VcXsrv 1.15.2.0, but still
       compatible with Windows XP. It also has its bundled OpenSSL updated to
       1.0.1j. It is compiled with Microsoft Visual C++ 2013 and contains 1
       X2Go-specific change, winmultiwindow.patch. This patch fixes an issue
       when resizing the NX-proxy window on specific multiple monitor setups.
       (Thanks Oleksandr Shneyder for the patch) (Fixes: #568) (Fixes: #594)
     - Windows: Port from MinGW 4.4 + Qt 4.8.5 to MinGW 4.8.2 + Qt 4.8.6,
       including fix for QTBUG-38706 (Fixes: #474, #603)
     - Windows: Fix missing VcXsrv/zlib1.dll . The impact of this bug was that
       VcXsrv would not start if the cwd was changed from the x2goclient
       directory. (The start menu and desktop shortcuts do have the x2goclient
       directory as the cwd. So they were not affected.) (Fixes: #587)
     - Windows: Make the desktop shortcut optional during install,
       but still the default.
     - Windows: Upgrade libssh from 0.5.5 to 0.6.3. This fixes connecting to
       hpn-enabled SSH servers. The Pageant support patch from the KDE Windows
       project was ported to 0.6.3 by myself and Mike Frederick.
       (Gmail: psududemike) (Fixes: #590)
     - Windows: Win32 OpenSSL updated from 1.0.1h to 1.0.1j, which fixes the
       CVEs announced on 2014-08-06 & 2014-10-15.
     - Windows: Replace Cygwin Bash (sh.exe) with Cygwin Dash (ash.exe renamed
       to sh.exe). This also means fewer Cygwin .DLLs are bundled.
       (Fixes: #636)
     - Windows: cygwin packages (excluding OpenSSH, which is at the patched
       version of 6.6.1p1-3-x2go1) updated from latest versions as of 2014-06-09
       to latest versions as of 2014-10-18. This includes openssl 1.0.1j-1, which
       fixes the CVEs announced on 2014-08-06 & 2014-10.15.
       (Cygwin openssl was also individually updated in 4.0.2.1+hotfix1+build2,
       but only to 1.0.1i-1.)
     - Windows: Build nxproxy.exe with Cygwin's libpng 1.5.x rather than 1.2.x.
       (This may improve performance when PNG compression is selected.)
     - Windows: Build cygwin openssh without krb5 or tcp_wrappers support because
       X2Go Client for Windows does not use either feature.
       (On Windows, Kerberos 5 (GSSAPI) support is provided by PuTTY.)
     - Windows: Fix text not being rendered properly at end of NSIS installer
       (Fixes: #597)
