Hi Mike, You can disable ZLIB in libssh (we didn't really need it) in DefineOptions.cmake You can find the libssh package with all patches applied hier: http://code.x2go.org/releases/libssh-with-pagent.patch/libssh-0.5.5.zip regards, Alex Am 17.03.2014 05:23, schrieb Michael DePaulo: On Fri, Jan 24, 2014 at 9:20 AM, Michael DePaulo mikedep...@gmail.com wrote: On Fri, Jan 24, 2014 at 9:14 AM, Oleksandr Shneyder o.shney...@phoca-gmbh.de wrote: To be able build current X2Go Client code on Mac or Windows you also need a libssh with this two patches. @Michael DePaulo.

Bug 448 was introduced as a Windows-specific regression when the Windows builds switched from KDE's 0.5.3 libssh build to your libssh 0.5.5 build. Could you please rebuild libssh with the patch listed in 448? I can confirm that it applies cleanly to libssh 0.5.5 with your 2 patches applied. (Note: I did try to build libssh 0.5.5 myself, but ran into an issue specifying the ZLIB_INCLUDE_DIR with CMAKE. If you already have the libssh build environment setup, it would be much easier if you could just rebuild with this 1 addtl patch.) -Mike#2 -- --- Oleksandr Shneyder| Email: o.shney...@phoca-gmbh.de phoca GmbH| Tel. : 0911 - 14870374 0 Ludwig-Feuerbach-str. 18 | Fax. : 0911 - 14870374 9 D-90489 Nürnberg | Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Hi Michael, hi Mike, I'll modify source code so, that build process will check if this files are present. However, this feature should be necessary implemented in all nightly and testing builds for *all* platforms. regards, Alex Am 02.03.2014 22:51, schrieb Michael DePaulo: Great, I'll do add it to either the windows bash script or the windows .bat script (My current design is that a bash script calls a .bat script to do the actual building, similar to how a bash script calls pbuilder to do the actual building for debian ubuntu.)

I am using the standard setup which has worked for 4.0.1.3: mingw32 4.4 QT 4.8.5 X2Go-WinBuilder VM (WIn7 64-bit SP1) See attached logs. They are what happens when I run the last 2 commands mentioned in this list: $ cd x2goclient $ PATH=%PATH%;D:\MinGW\libexec\gcc\mingw32\4.4.0\ $ config_win.bat $ mingw32-make From this page: http://wiki.x2go.org/doku.php/wiki:development:build-howto-mswin:x2goclient Note that there are errors in both config_win.bat's output, and in mingw32-make's output. And they seem to be related to resources.rcc not finding files. The reason for the FTBFS is a series of commits from Alex adding some methods for retrieving more detailled information on the current X2Go Client build during runtime. Basically, that is a nice-to-have feature esp. during development cycles. The not so good aspect is, that currently all automatic (and the win32) builds fail (for Linux builds see http://jenkins.x2go.org). @Alex: The problem is the git executable. Basically, we have to assume that (a) the .git folder is not present (e.g. in the tarball releases) and (b) the git command is not available in the build environment. So my suggestion would be: o create the txt/git script before the build (I can add that to our buildscripts on code.x2go.org) o copy the changelog file via debian/rules (for the .deb package) and via x2goclient.spec (for the .rpm packages) o only make the --git cmdline switch available if ./txt/git exists o (and maybe rather rename --git to --git-info) o only make the --changelog cmdline switch available if ./txt/changelog exists So basically, please split the work up into X2Go Client code: (todo Alex) o offer --git(-info) and/or --changelog if the corresponding ./txt/* files exists during runtime debian/rules | x2goclient.spec (todo Mike#1): o create ./txt/changelog x2go-build-deb-package | x2go-build-rpm-package (todo Mike#1): o create the git information in ./txt/git-info winbuider.bat (todo Mike#2) o create the git information in ./txt/git-info Package maintainers of distros should (be able to) omit the creation of ./txt/changelog | ./txt/git-info. The upstream version and the package release should bear all info that is needed.

[X2Go-Dev] libssh changes. Information for package maintainers
Hello, as you know, I made some changes in X2Go Client code. Especially important is that X2Go Client do not open for every reverse tunnel a new ssh connection any more. To make it possible, I made some improvements in libssh. The patch is already accepted by libssh team and Mike will take care about linux packages. The libssh patch for reverse connections is here: http://code.x2go.org/releases/libssh/libssh-0.5.x-accept-forward.patch I have also found another one issue with libssh, however I have not yet an answer from libssh team if they will accept this patch. It is very important for Mac Client to use libssh with this patch. In other case you can expect the poor performance of X2Go Client. You can find a patch here: http://code.x2go.org/releases/libssh/libssh-0.5.x-unblock.patch To be able build current X2Go Client code on Mac or Windows you also need a libssh with this two patches. @Michael DePaulo. Please apply this two patches on your libssh source tree.

Re: [X2Go-Dev] Issue with 100% cpu usage in x2goclient + libssh 0.6.0
Hello Orion, We can't wait forever in ssh_select, we must perform other tasks in loop, for example accepting forwarded connections. However, I have already increased a select timeout and made a lot of other changes in ssh code of X2Go Client. The changes are not yet in master GIT because they depend on reverse forwarding fixes, that I made to libssh. As soon as we have libssh packages ready, I'll push my local commits to GIT. regards, Alex Am 22.01.2014 22:36, schrieb Orion Poplawski: With libssh 0.6.0, x2goclient consumes 100% cpu on connection. The trigger for this is that ssh_select() was rewritten to use poll() instead of select(). poll() has a timeout in milliseconds, select() in microseconds. x2goclient requests a timeout of 500 microseconds which is getting rounded down to a timeout of 0 milliseconds for poll(). However, this still seems to point to some poor coding on the part of x2goclient that we're using such short timeouts. Why can't we just wait forever in ssh_select() in SshMasterConnection::channelLoop() ? -- Oleksandr Shneyder | Email: o.shney...@phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Bräuhausgasse 9 | Fax. : 0911 - 14870374 9 D-82205 Gilching| Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

This bug only seems to happen if GSSAPI auth succeeds. If I purposely misconfigure the x2goserver's kerberos (e.g., I run samba's net -P ads keytab flush command to clear the contents of /etc/krb5.keytab), I instead get the erorr message Check your GSSapi configuration or choose another authentication method.

Other than that and unless I am reconnecting (see the next line), the x2go client window is frozen. If I close x2go client and reconnect, I am prompted to resume (or suspend/terminate) the session.

Re: [X2Go-Dev] Do we really need an x2gouser
Hello Reinhard, in central DB different sessions information is stored. For example, used display numbers and ports. x2gostartagent look in the DB when assigning display and ports for new sessions. Historical x2ho has only postgresql support. In postgres version users have access only to his own entries in sessions table. sqlite support was developed for small one-server installation wheres installing of postgresql is oversized. To avoid users modify session data only user x2gouser has direct access to DB. For complex setups with central user administrations you should use postgresql instead of sqlite. regards Alex Am 14.12.2013 23:26, schrieb Reinhard Tartler: Hi, can someone please remind me again why we need a sqlite database that is shared for all users? It allows users to see what other users are currently having running sessions, which I frankly don't consider very important. It could even be considered a privacy issue. If there isn't a good reason for a shared database, why don't we have x2go users have their own sqlite database in their home directory? This would allow to get rid of the x2go user and all suid/sgid complexity that comes with it. Background, I'm trying to have my new employer deploy x2go, and I'm currently having trouble to explain this point.

Oleksandr, 1st of all, thank you very much for implementing this! As someone with a windows AD domain at home and at work, this feature is extremely useful when it does work. 2nd, as the new windows package maintainer, I uploaded x2goclient-4.0.1.2-pre03 (and x2goclient-4.0.1.2.interims-pre03) with the current plink.exe and pscp.exe (versions 0.63) to the x2go server. Mike Gabriel will most likely make this pre03 version available to publicly download tomorrow (he just went to bed.) 3rd, it appears as if whenever plink has any sort of error, having GSSAPI auth enabled for the session crashes the Windows x2goclient. It took me a bunch of effort to make plink's GSSAPI authentication work, I intend to document this work on the wiki. Note that my setup is a Windows Server 2012 AD domain controller, x2goserver 4.0.1.9 from EPEL running on centos 6.4 64-bit with Samba 3.6's winbind for domain membership, and a Windows 8.1 64-bit domain member client (I also tested the x2goclient on my Windows Server 2012 DC also). But the bottom line is that I expect LOTS of Windows users to run into x2goclient crashes whenever they enable GSSAPI. They can avoid these crashes by disabling GSSAPI for the session (so it's not as severe a problem as bug #109), but I would strongly prefer if you could fix the crashes before we launch 4.0.1.2. If you can't make Windows x2goclient easily fall back to password auth when GSSAPI auth fails, at least give the user a message to disable GSSAPI auth. -Mike ___ X2Go-Dev mailing list X2Go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev -- Oleksandr Shneyder | Email: o.shney...@phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Bräuhausgasse 9 | Fax. : 0911 - 14870374 9 D-82205 Gilching| Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Re: [X2Go-Dev] building X2Go Client for MS Windows
Hi, you don't need to have cygwin to build x2goclient for windows. All you need for building x2goclient is Qt+MinGW and libssh. Building of Qt-Applications on Windows is just the same as for every OS - qmakemake. For x2go client - config_win.bat make. It is as easy as piece of cake. It is enough if someone want to modify X2Go Client and build it for Windows. All other components - X, pulse, nxproxy, sshd can be easily copied from X2Go Client installer. I see no reason why some one should want to make any changes in this components and why it should be a part of X2Go documentation. Cygwin is used for compiling nxproxy and for sshd. Yes, I know, there is a newer version of Cygwin as legacy version used with x2goclient at that time. I have tried it, and there are many changes regarding registry and directory structure in it. It is not possible without spending a lot of work to use it with x2goclient. And I'm not ready to do this work for free. Every one who want to do that is welcome. regards Alex Am 13.03.2013 09:41, schrieb Mike Gabriel: Hi Michael, hi Alex, On Mi 13 Mär 2013 07:59:42 CET Michael Kromer wrote: recently some of you have (successfully) attempted to build X2Go Client from source on MS Windows systems.

Since cygwin provides newer packages http://cygwin.com/cgi-bin2/package-grep.cgi?grep=openssh I think there are options. We would even sponsor the open step-by-step documentation to some extent. Just contact me for details. That is good news and would be a great contribution to the transparency of the project. I will allow people to easily build customized versions of X2Go Client suitable for company deployment. @Alex: will you get in contact with Michael?

Re: [X2Go-Dev] fuse and X2Go printing
Hi Stefan, I would prefer the solution suggested by Morty. Actually, I already thought about it and i want include it in new implementation of x2goclient. X2goclient will simply check a spool directory on server and download a print jobs in PDF format via existing libssh connection. This solution is much simpler, no need a cups, lpr, or ssh daemon running on a client and implementation is just the same for all operating systems. I can also implement this solution in current version of x2goclient if somebody will sponsor the development. regards Alex Am 20.02.2013 09:51, schrieb Stefan Baur: Am 20.02.2013 09:22, schrieb Moritz Struebe: On 2013-02-19 20:20, Stefan Baur wrote: I can see that sshfs makes sense when you want to exchange files between host and client, but for printing it sounds like overkill. Well, actually the best thing to do is probably letting the client ls every sec (it's prabably not worth the trouble to inotify) and then scp to temp. But it needs someone to code that. After all, a x2go started as a proof of concept rather then a product. Uh, no. You see, currently, I'm not using X2Go to connect via the internet, it's all happening in my local network(s), so I don't have to worry about encryption and compression for print data. In this scenario, I'm simply letting the CUPS servers talk to each other directly, which works fine when the client is using Linux (or Mac OS, I guess - after all, the Apple guys kinda bought CUPS). For Windows, I'm using the LPR Daemon that is an optional windows component, so to the server-side CUPS the Windows computer looks like a network printer. For printers that aren't supported by CUPS (the el-cheapo GDI-only ones) I'm using a combination of redmon (a printer port redirection tool usually used with ghostscript for Windows to create PDFs) and a free PDF viewer: CUPS sends the print job in PDF format via port 515/lpr, redmon accepts it, passes it to the PDF viewer, which in turn uses the windows printer driver to create the print output. If properly set up, all this happens in the background, with no user interaction required and no windows popping up. A bit of a hack for Windows, I admit, but it works just fine. Now, it would be nice if that would work over the internet, too, by simply forwarding the proper ports through the already existing ssh tunnel created by X2Go. That way the print data would be encrypted and compressed as well. That's why I don't see an advantage in mounting a remote filesystem via SSH (which is a Pandora's Box of its own) simply to be able to print. And even if you don't want to use LPR and redmon on Windows, there'd still be the option of setting up a netcat listener on the client that only accepts connections from localhost (the tunneled port connecting to it), have that one write its data to a file, and print upon completion. Something as simple as (pseudocode, not actual bash/batch) printfile=$(makesafetempfilename) # note that we're using port 9100 - raw network printer mode # rather than 515 with its LPR protocol overhead, so we don't # need to have the windows LPD and redmon installed while nc -l -s 127.0.0.1 -p 9100 -w 1 printfile; do process_and_print printfile # this is where you call the PDF tool delete printfile printfile=$(makesafetempfilename) done would probably do the trick. Note that Windows netcat (at least the copy I found) doesn't support -q, so you have to improvise with -w. The way netcat is called it terminates upon completely receiving the file, and the following tasks are not started before netcat terminates, so there is no need to check for completeness of the file. Also, should a user fire off another print job before the while loop returns to its head and restarts netcat, CUPS will simply assume the printer is busy/offline and retry after a few seconds, so no print job is lost. I'm sure that even integrating such code (with a listener and the option to pass a temporary file to a PDF tool) *directly* into the X2Go client, rather than having it as an add-on component, would be a simple task for a skilled programmer. -Stefan ___ X2Go-Dev mailing list X2Go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev -- Oleksandr Shneyder Dipl.

Re: [X2Go-Dev] fuse and X2Go printing
I don't agree with you, Stefan. Simply redirect the ports is no solution for X2Go connections over Internet. The job should be converted in PDF on server or it will be just too big. So as result we will have a PDF File on server and it not a problem it all to download it to client system.

X2goclient will simply check a spool directory on server and download a print jobs in PDF format via existing libssh connection. Again, this sounds like unneccessary overhead. You're turning a stream of data into a file, you need to have some sort of monitoring system (either polling regularly or triggered by the change to the filesystem) and what for - to turn the file into the stream of data that it originally was. With all this happening on the server. This solution is much simpler, no need a cups, lpr, or ssh daemon running on a client and implementation is just the same for all operating systems. Well, you need the server-side cups or you wouldn't be able to print, with either solution. And my previous post contained a solution where you would only turn the data stream into a file after it arrives on the client, not on the server as well. This would work without *additional* cups, lpr or ssh on the client - it uses whatever the client (Linux, Mac OS and Windows) normally uses for printing and only needs an open tunneled port in the existing SSH connection. Though, to be honest, I would simply connect to the existing CUPS via tunnel if the client uses Linux or Mac OS. No need to add complexity there. -Stefan ___ X2Go-Dev mailing list X2Go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev -- Oleksandr Shneyder Dipl.

This feature was sponsored from Mirco Rohloff from Rohloff AG - http://www.rohloff.de With this feature you can open direct RDP connection using installed on the client system RDP client program without X2Go proxy. It could be useful in mixed environments with both Linux and Windows TS. This feature is only available for Linux client. To use it, choose Session type Connect to Windows terminal server in Session preferences. You should also check Direct RDP Connection. After that you can configure additional setting in tab Settings. In this tab you can choose display resolution, RDP client to use and also specify additional command line parameters. I suggest to use direct RDP connections only over LAN or VPN connections. Over Internet using X2Go proxy is faster and securer. You can install X2Go Client-3.99.3.0 which contain this feature from our repository heuler 2. X2Go client with old (0.9.6) Pulseaudio. This feature was sponsored from Stefan Baur from BAUR-ITCS UG - http://office.stefanbaur.de/ This is an alternative interims X2Go Client for Windows which includes an obsolete version of Pulseaudio. You can try this version if you have problems with sound in Flash. You can download a Windows binary from here: http://code.x2go.org/releases/binary-win32/x2goclient/with-old-pulseaudio-0.9.6/x2goclient-3.99.3.0.interims-pre2-setup.exe Regards, Alex -- Oleksandr Shneyder Dipl.

Re: [X2Go-Dev] x2goclient-3.99.2.1 plugin crash
Hello Jan,
I have made some fixes in X2GoPlugin code for several minutes:
http://code.x2go.org/gitweb?p=x2goclient.git;a=commit;h=d4d0fe38610d3e514dc2e4e259ce8f103e4ac535
Please test it.
The documentation in our wiki about X2Go Plugin configuration was too
old. Since we using qtbrowserplugin for building X2Go Plugin we don't
need a configuration file any more. All settings should be saved direct
in HTML-File. I have the wiki page also updated, please check it:

that initWidgetsEmbed was never called.

In this script we then can set any env variable needed (like LD_LIBRARY_PATH) before the published application starts. I disrecommend setting such variables within the application call on the client-side. Opinions?

It allowed me to setup access rights depending no the source ip and login of users and time of the day. For example I have one group of user that can login from the internal network only, while another group of road warriors that can log both from local or remote location. It is very cumbersome to do at the ssh level, and the nxacl file was very handy to do this. Perhaps there is a way to reproduce this behavior in x2go, and sorry if I missed it. On the file ACL point of view, I thing the apparmor/selinux/nameyourown framework way to be much more clean. I don't like much the idea to change ACL on programs because of maintainability, for example on software upgrade and all (and IMHO security needs maintainability), and I think a broader framework to be more suitable (no opinion on which one). Again, due to the way x2go works it is not possible to enforce this. x2go is just a very efficient way of ssh -X. If it wasn't for maintainability, we could even get rid of the sqlite database and start the x2go manually. Morty +1 The main idea of X2Go is to use existing UNIX tools for data transport, authentication, access control, etc. This is why we decided to develop X2Go and not to improve, for example, freenx. Any Idea to provide something like nxacl will be refused. Regards, Alex -- Oleksandr Shneyder Dipl.

The way I see it, pulseaudio on the client just flat out refuses to run while %USERPROFILE%\.x2go\pulse\.pulse\%COMPUTERNAME%-runtime\pid exists. Proof for my theory: When I close all x2goclient.exe-related tasks (ssh and whatnot) and run x2goclient.exe again I still have no sound when reconnecting. BUT: as soon as I close x2goclient.exe, manually delete the pid file and restart x2goclient.exe, I *do* have working sound when reconnecting. Of course, suspending *while the video is running* will have the effect described by you, but that's *not* the issue I'm reporting. I'm waiting for the video to finish (I was originally tryingo to find out if the pulseaudio stability issues when playing long videos are gone), so there is no active application like flashplayer trying to push data to pulseaudio. -Stefan okay, it's strange.

the icons are transferred from the server, certainly. You can find a

- x2goclient is configure _not_ to minimize into the systray. After
establishing a published application session I see for buttons in
the
center of the blue window area of x2goclient. The buttons do not
fit in
there (they overlap).
I see, you font size is just too large. I'll think, how I can solve this
problem. I should find another place for Applications... button.
That might well be, And: people tend to customize their desktops, so we
have to react to that with flexible widget geometry definitions.
It might also be a i18n issue (count('Ordner freigeben') count('Share
folder')).
Yepp, It will be completely changed in new version of client.
- Is there a concept for evaluating i18n parts of desktop files?
Application
links appear in English still.
Actually, all localized strings from desktop files are transferred to
client. For example, if you client localization is de_DE, the strings
Name[de] and Comment[de] will be used to describe your application in
x2goclient. If this fields are not present in desktop file, Name and
Comment will be used.
Ok, I have tested again. Translation of menu items works.
- Alex, whenever we are about to release the new code, we should make
a call
for translation, so that i18n files are updated with the new version
Good idea. But I don't think, that it is a target for developers. I
think we should found a localization group, which will take care about
localization. Volunteers?
A small team has already gathered:
x2go-i...@lists.berlios.de
However, they (a) need dev support for committing their changes to Git
and (b) the devs have to say: ,,Ok guys, all text elements are now in a
state that they will not get changed again tomorrow, please translate.''
The translators won't be able to know that by themselves. So: we
developers send out the ,,call for translation''.
Okay

Hi,
It is really nice that somebody want to make x2goclient working on Mac.
Unfortunately, building x2goclient for Mac is not enough. There are some
features in x2goclient (especially managing of nx-proxy window) which
can not be written with Qt methods, but only with system API (libx11 and
winapi). In addition, there are many changes from version to version in
Mac OS itself. Especially it relevant to X11. The behaviour of X11 can
be changed even within the same version of Mac OS with every new version
of X11. So, you should be sure, that changes you made in x2goclient
working with actual versions of mac and X11. Please be sure also, that
changes you making in code of x2go client will not break its
functionality on other systems and you always using the
#if defined ( Q_OS_DARWIN )
#endif
clauses
I still plan to rewrite code of x2goclient to make it more
understandable for other people and make hacking of it easier.
Unfortunately, in moment I have no time for it.
regards,

Re: [X2Go-Dev] Traffic shaping nightmare - missing SSH TOS bits
Am 21.02.2012 07:05, schrieb John A. Sullivan III: Hello, all. I've been working on a project to implement traffic shaping to conform to 95th percentile billing including our X2Go virtual desktops. One of the challenges is prioritizing the interactive X2Go traffic (screen, keyboard, mouse) differently from bulk traffic like local share transfers, printing, and possibly sound. I thought this would be trivial because of the SSH transport since SSH sets the minimize-delay bit for interactive traffic and the maximize-throughput bit for bulk transfers. Thus we could distinguish the packets by looking at the TOS bits. This is how the default Linux pfifo_fast qdisc does it anyway. I took a packet trace just to confirm it and, to my horror, I see that we are not setting any of the TOS bits and thus not prioritizing interactive traffic even with the default traffic shaping. I'm guessing this is a casualty of moving to libssh. Is there any way to set the TOS bits for interactive to 0x10, bulk to 0x08 as it is in OpenSSH?. It would be really nice if sound could be configured either way according the the administrator's preference. Unfortunately, I did not see anything in the libssh documentation to show how to do this although I do not claim to understand it. This is a critical issue for any WAN based deployments like ours.

Simple making links /usr/lib/nx/X11/Xinerama/libNX_Xinerama* - /usr/lib/nx/X11/Xinerama/libXinerama* don't work, because due to new build procedure libXinerama is linked against libNX_Xext and libNX_X11, not libXext and libX11. I don't know about the Xinerama/ subdirectory, it does not get installed by nx-libs. It is a X2Go patch. It enable support for more as one display (for example thinclients with multihead) But symlinking of /usr/lib/nx/X11/libXext.so.6 to /usr/lib/nx/X11/libNX_Xext.so.6 should work (talking about LD_LIBRARY_PATH- using programs) as long as the SONAME stays NX_Xext for automatic dependency finding of rpm (and perhaps deb?).

There is no need to make such changes in X2goClient. It is common
practice to create translation files in lower case. See Qt
documentation:
http://developer.qt.nokia.com/doc/qt-4.8/qtranslator.html#load
All what you need to use zh_TW localisation is to create translation
file x2goclient_zh_tw.ts (in lower case) and add this translation to
project file x2goclient.pro:
TRANSLATIONS += x2goclient_zh_tw.ts
and to resources file resources.rcc:
filex2goclient_zh_tw.qm/file

Alex

[X2go-Dev] replace for kde/lxde/gnome-bindings and x2godesktopsharing
Hello dear X2Go users, I want to share with you my idea to create new application, which should replace such packages as kde/lxde/gnome-bindings and x2godesktopsharing. The reasons to create such application are: - reduce effort of developing and supporting bindings for every desktop environment - put all x2go related settings in one place. That should improve usability - add some new features The application should provide existing features: - display and manage(open, demount) exported shares - manage sharing of display (x2godesktopsharing) if display sharing is configured - suspend X2Go session The application should be able to communicate with x2goclient and provide some new features: - switch between full screen and window modes - enable/disable multi display (Xinerama) support - send x2goclient command to open export directory dialog. This should be very useful if X2Go session is running in full screen mode or x2goclient is minimized to system tray. I'll be appreciative for your comments and for suggestions about this application's name. best regards, Alex -- Oleksandr Shneyder Dipl.

Today I have improved client-side session title renaming in x2gostartagent (package: x2goserver). And: I have added a session profile parameter to .x2goclient/sessions when using pyhoca-gui (python-x2go). The new session profile parameter's name is: sessiontitle. If sessiontitle is set to a non-empty string, python-x2go will export the env variable ,,X2GO_SESSION_WINDOW_TITLE before calling x2gostartagent on the server-side. The x2gostartagent script will notice that $X2GO_SESSION_WINDOW_TITLE is defined and it will use this string as the session window title (+ X2GO-session_id in parentheses). @Alex: could you please take a look at my latest x2goserver commits? Maybe such a feature could be interesting for x2goclient itself. It would be nice if we could use the same session profile parameter (i.e. ,,sessiontitle''). x2go client and plugin using window title for searching window with agent session. That will be needed if client should change parameters of such window, for example - hide window decorations, resize window or embed it in other window.

As result you can get a wrong behaviour of a client, if you starting a session with new client and resuming it with old one. I don't think, that this feature is important enough to break compatibility with old versions of clients. I have reverted the server-side changes in x2gostartagent. Instead, I have changed x2gostartagent in a way that it will check for the x2gofeature X2GO_FEATURE_SESSIONTITLE and if that is available it will call a subscript. This feature X2GO_FEATURE_SESSIONTITL and the corresponding subscript ,,x2gosessiontitle'' are part of a new extension package I have added to x2goserver and called: x2goserver-pyhoca, an add-on package to improve functionality of pyhoca-gui and pyhoca-cli. This package will only be suggested by the core x2goserver package, so it will not be installed if people do not actively select it for installation. This package currently contains two scripts only used by pyhoca: x2gosessiontitle x2gosetkeyboard The x2gosessiontitle subscript will then only generate a custom session title if the env var X2GO_FEATURE_SESSIONTITLE is set to ,,enabled''. This has to be done from the client when launching x2gostartagent. I hope this approach allows us to keep the session title functionality and stay also compatible with old client implementations and between pyhoca and x2goclient.

This appears to have affected the SNMP over SSH project:

+naglesource=blots=F8Iw-pvQxdsig=f5dfy0K0ewzSZOhqzTJRSKsDKZ8hl=enei=KppzTrCZD4LJgQeMxLzzDAsa=Xoi=book_resultct=resultresnum=1sqi=2ved=0CBwQ6AEwAA#v=onepageq=libssh%20naglef=false
This is in section 4.1. The difference was a latency of over 800ms to
one of under 60ms. That seems to be about what I am seeing. There
is a
delay of roughly a second and then the rest of the screen comes
through.
Thanks - John
Indeed the TCP_NODELAY (which means: turn Nagle off) is not set for
the ssh tunnel in X2goClient. It probably is for the SSH connection
itself, as the SNMP patch has been reported to libssh upstream and
their patch suggestion has been sensible. However, for the SSH tunnels
built up for X2go this TCP_NODELAY option does perhaps not get set.
@Alex: would this patch fix that in x2goclient???

I don't think that that can be helpful. This part of code is only for
reverse tunnel which is used for FS forwarding and Pulse Audio.
I took another close look at the code of sshProcess.cpp. The patch is
applied to the method sshProcess::tunnelLoop. This method only gets
execute in sshProcess::startTunnel.
The call is:
quote
if (!reverse)
tunnelLoop();
else
{
blablabla
}
/quote
So this makes me think that tunnelLoop() is not for reverse tunneling
but for the graphics tunnel.
Could you take another look please?
Thanks,
Mike
hmmm, ok, seems you are right :) Can you apply this patch to source tree
and I'll try to build a windows binary tomorrow.
regards,
Alex

[X2go-Dev] cups-x2go and new x2goserver
Hello list, I've made some small changes in cups-x2go to make it work with actual version of x2goserver. The changes are already in GIT. @Mike: the preinst script of obsolete package x2goprint has modified sudoers file to allow user x2goprint execute program /usr/bin/x2goprint. This script has also added a user x2goprint to system: #useradd -s /bin/bash -d /var/spool/x2goprint/ -r x2goprint #mkdir /var/spool/x2goprint/ #chown x2goprint /var/spoo/x2goprint/ #chmod 700 /var/spool/x2goprint/ Now, this job user should do by himself. Creation process of x2goprint is not documented in our wiki. This process should be good documented or made by some configuration script. regards, alex -- Oleksandr Shneyder Dipl.
