Subject: X2goclient on Windows: sshd.exe does not start.

Date: Wed, 29 Jan 2014 18:08:57 +0100

Package: X2goclient
Version: 4.0.1.3

Client host: windows xp
Server host: debian wheezy

- When enabling support for printer sharing, or sharing a folder, sshd.exe
does
  not start, and so these features are not available.

- If I launch manually sshd (from what I understand x2goclient launches from
  reading source code) sshd.exe launches and stays until I kill it:
    "C:\Program Files\x2goclient\sshd.exe" -D -p 7022 -f
"/cygdrive/c/Documents
	and Settings/User/.x2go/etc/sshd_config" -h "/cygdrive/c/Documents and
	Settings/User/.x2go/etc/ssh_host_dsa_key"

- Every time I try to share a folder with the session running, I can see
on the
  process manager ssh-keygen is launched.

- Server host shows the remote folders as mounted on /proc/mounts, so
accessing
  them makes a process hang.

- Firewall is disabled on client host.

Forgot to mention (thanks to mikedep), this is a windows sp3 32 bit.

Subject: I reproduced this bug

Date: Wed, 19 Mar 2014 22:53:06 -0400

I did a bunch of testing. Note that most of the earlier test results
were not valid because i was probably not in the "fuse" group:
https://docs.google.com/spreadsheet/ccc?key=0AmL_OrCln9ShdHcxbTQ3amJZdlp1b3pkcWpveWtwSlE&usp=sharing

Conclusions:

1. This bug is present in X2Go Client 4.0.1.2 and later, including the
nightly 4.0.2.0 builds.

2. This bug affects Windows XP 32-bit SP3, but it does not affect
Windows 7 32-bit SP1 nor does it affect Windows 8.1 64-bit ("Update 1"
was not installed.) It is safe to assume that only XP, server 2003,
and server 2003 R2 are affected

3. This bug is not present in 4.0.0.3. (there was a gap in X2Go Client
Windows builds between 4.0.0.3 and 4.0.1.2.)

4. Across all 3 aforementioned Windows Client OSs with X2Go Client
4.0.0.3, sshd.exe does start. However, folder sharing does not work;
the share never shows up when you run "df" and it is not present in
the usual path under /tmp/ . (I did not test printer sharing, but I
did test all 3 OSs.) That is probably another bug, but it was
obviously fixed. I will not be writing it up.

X2Go Component: src:x2goclient
Version: 4.0.2.1-0x2go1
Status: RELEASE
Date: Fri, 11 Jul 2014 12:23:59 +0200
Fixes: 235 364 365 421 478 498 502 514 528
Changes: 
 x2goclient (4.0.2.1-0x2go1) RELEASED; urgency=low
 .
   [ Mike Gabriel ]
   * New upstream release (4.0.2.1):
     - Fix FTBFS on arm64 (and others) architecture. (Fixes: #498).
     - Only show session name in notification bubbles with debugging
       enabled. (Fixes: #364).
     - New command line option (--keep-trayicon). With that options set,
       we force X2Go client to only use the default "accelerated X" as
       system tray icon (and prohibit usage of the session's icon as
       tray icon). (Fixes: #365).
     - Provide more meaningful messages on SSH errors (host pub key not
       found, export pub key not found, authorized_keys file not found).
       For SSHd startup failures provide different messages on Windows
       and non-Windows machines. (Fixes: #235).
       FIXME: add detection code to report SSH daemon startup failures.
     - Add new cmdline option --hide-foldersharing. If used, all GUI
       elements related to exporting client-side folders to X2Go sessions
       get hidden. (Fixes: #514).
     - Update COPYING file (to update FSF address).
   * debian/control:
     + Add dbg:package x2goplugin-dbg.
 .
   [ Clemens Lang ]
   * New upstream version (4.0.2.1):
     - Re-add Info.plist file (which got removed by accident in commit 91cf6c6).
       (Fixes: #502).
 .
   [ Oleksandr Shneyder ]
   * New upstream release (4.0.2.1):
     - Hide GSSAPI options on direct RDP connections. (Fixes: #478).
     - Search X-Server in /Applications/Utilities/XQuartz.app on Mac.
     - Wrong cmd line option throw error dialog if running not from terminal.
     - Add command line option "close-disconnect", which make client close after
       session is disconnected.
     - Don't start pulse on Windows, until we really have to start a session
       that requires pulse support.
     - Check if sound is activated before starting pulse.
     - Fix starting sshd on Win XP. (Fixes: #421).
     - Fix "fullscreen" mode on Windows 7 with multiple monitors.
 .
   [ Mike DePaulo ]
   * New upstream release (4.0.2.1):
     - Windows: Prevent high PulseAudio CPU usage on Windows XP by lowering
       PulseAudio's CPU priority from "high" to "normal" on XP specifically.
       Also do so on Windows Server 2003 (R2) (Fixes #526)
     - Windows: Enable PulseAudio log when --debug is passed.
     - Windows: Fix compatibility with current PulseAudio master branch
     - Windows: Reduce size of NSIS installer by switching to lzma solid compression
     - Windows: cygwin packages (inluding patched OpenSSH 6.6.1p1-3) updated from
       latest versions as of 2014-04-08 to latest versions as of 2014-06-09. This
       includes openssl 1.0.1h-1, which fixes the 6 CVEs announced on 2014-06-05.
       (Cygwin openssl was also individually updated to 1.0.1h-1 in
       4.0.2.0+build4.) This also includes migrating from libjpeg to
       libjpeg-turbo, which reduces CPU usage of nxproxy.)
     - Windows: Download and compile nx-libs-lite from the release tarball,
       rather than from git, so that the patches are actually applied
     - Windows: nx-libs-lite updated from 3.5.0.22 to 3.5.0.27
       (linked against aforementioned cygwin package versions)
     - Windows: Win32 OpenSSL updated from 1.0.1g to 1.0.1h, which fixes the 6
       CVEs announced on 2014-06-05.
       (Win32 OpenSSL was also updated to 1.0.1h in 4.0.2.0+build3.)
     - Windows: VcXsrv (XP Compatible) updated from 1.14.3.1 to 1.14.3.2.
       Fixes CVE-2014-0209, CVE-2014-0210, and CVE-2014-0211
       (VcXsrv was also updated to 1.14.3.2 in 4.0.2.0+build2.)
     - Windows: Switch from regular NSIS 2.46 to Unicode NSIS 2.46.5
       (Fixes: #528)
