[PATCH 0/7] Accumulated changes
by Mihai Moldovan 26 May '12

26 May '12

Hi all, I hereby present you a patch set of accumulated changes. Each patch should be applied in order. The first patch adds automatic translation processing to the x2goclient.pro file. Developers will have to update the translation templates by hand though, as usual. Template to Qt locales conversion is then handled by x2goclient.pro. Patch two just includes some minor whitespace/style fixes for x2goclient.pro. Patch three adds support for PPC compilation and adds the oddly forgotten Info.plist directive to x2goclient.pro. Patch four is another style fix for the copyright notice on sshmasterconnection.cpp. Patch five changes the way the host is given to libssh based on official Qt documents. Patch six facilitates turning SSH packet logging on or off. Patch seven, eventually, introduces support for Mac OS X 10.4 Tiger. Together with the NX library patch, it also adds support for using nxauth, which is mandatory on all versions of OS X. I wonder how this stuff worked in the first place before, we should have seen a lot of problems without nxauth. Maybe some of Stephans and Jans problems in the past were actually caused by this all along. I will upload new versions for both 10.5 and up and 10.4 in some time (have to rebase one build machine first.) Another email regarding Mac OS 10.4 support will come in due time. Best regards, Mihai

by Mike Gabriel 23 May '12

23 May '12

Hi all, NoMachine seems to have fixed the libcairo issue we discussed lately. I will take a look at their changes tomorrow. Mike ----- Weitergeleitete Nachricht von sender-nxannounce(a)nomachine.com ----- Datum: Mon, 21 May 2012 22:52:10 +0200 Von: sender-nxannounce(a)nomachine.com Betreff: Fourth Maintenance Release of the NX 3.5.0 Node and Server packages An: mike.gabriel(a)das-netzwerkteam.de Rome, Italy, May 21, 2012 - NoMachine makes available updates to NX Node and Server software.

If you don't have the sudo utility installed, log on as superuser ('root') and run the commands without sudo. Otherwise you can use the graphical package manager provided by your Linux distribution. Instructions for RPM , DEB and tar.gz packages refer to the 32 bit package (i386) and can be easily extended to the 64bit package (x86_64 or amd64).

X2Go-Future
by Arnold Krille 21 May '12

21 May '12

Hi all, I am having some doubts about the future of X2Go and seeking for answers. I saw mails mentioning nx3.6 which seems a bit strange to me given that the next version of nomachine's nx is 4.0. And that is what makes me wonder about the future of x2go: The main parts of x2go (nx-agent and assorted low-level libraries) seem to go closed-source, at least as far as I can tell from their licensing documents. So what happens to X2Go? I love the work you guys did and do. Resuming sessions while changing desktop- geometry is real fun. Having responsive desktops over WAN where vnc just doesn't work, is real fun. Using locally attached usb-stick on the remote server is real fun. Which made me "force" my colleages switch from our old VNC-based setup to X2Go. Sadly the expirience suffered when we updated the nx- libs from 3.4 to 3.5: On WAN-connections its still usable but on LAN X2Go looses in speed and latency and responsiveness against VNC. Which my co- workers really hate. My hope was that next nx-libs might fix this. And they probably will, but not for us when there is a price-tag associated with it. So how to go on in our case? What is your future planning for X2Go? Do you have plans (and knowledge and manpower) to further develop the nx-libs on the open-source base? Do you have a promise from nomachine that the libs will go open-source again? Do you have plans to use a different x-protocol like vnc from tigervnc or turbovnc? (Combining the speed of tigervnc and the features of sessions and apps and storage-forwarding of x2go seems like a good idea to me currently.) Thanks for your answers! Have a nice weekend, Arnold

Windows X2Go client and Windows 8
by Stefan Baur 21 May '12

21 May '12

Hi Devs, just FYI: I tried to run 3.99.2.1-rc3 on Windows 8 (32-Bit) and it gets to the point where the connection is established and it tries to start the X server on the client, then it completely crashes Windows 8 (forced reboot). Attempting to run vcxsrv.exe on its own doesn't seem to do anything: There's no black X desktop showing up, but Win8 doesn't crash either. With Windows 8 schedluled for release in October 2012, I guess *someone* should take a look at this soon. -Stefan

Clipboard feature?
by Stefan Baur 21 May '12

21 May '12

Hi Devs, not long ago, someone (Alex?) posted a message that X2Go doesn't strive to be NoMachine NX and prefers to work as a glue between several freely available and already existing components (like, using ssh tunneling and FUSE for file sharing between server and client). One feature that NoMachine NX (and FreeNX) has is to limit the use of the clipboard: You can set it to work both ways, server -> client, client -> server, or not at all. How could that be mimicked if such a feature is not part of X2Go? -Stefan

[nx-libs] Reason for using quilt
by Mihai Moldovan 20 May '12

20 May '12

Hi, I'm wondering why you guys are using quilt for managing patches to the nx-libs repository. I see that the general purpose is to have the original nomachine source base intact/unchanged to track changes easily. However, quilt is a pain to use (i.e., omitting a patch in the series or changing it), especially taking into consideration that git _already is_ a SCM. Wouldn't it be easier to actually use multiple branches for that purpose? [nomachine]--{3.5.0}------------{3.6.0 (future)}----... \-->[x2go]-------\-->------------... where [name] is a branch named "name", {name} is a tag named "name" and the arrows denote merges. Note that we don't want to merge x2go project changes back into the original nomachine source, thus not merging the x2go branch into the nomachine branch. However, we _want_ to merge new versions of nomachine's source into the x2go branch at some point. Also, this setup is very flexible. If, for instance, you decide to still support the x2go nx 3.5.0 branch, even though nomachine nx 3.6.0 has been released, simply branch off the x2go branch, like this: [nomachine]--{3.5.0}------------{3.6.0 (future)}----... \-->[x2go]-------\-->------------... \-->[x2go 3.5.0]--------... Afterwards, the nomachine branch (tag 3.6.0) can then be merged into the x2go branch and the x2go 3.5.0 life on happily ever after. It is way easier to rebase a branch such as to not include a specific commit (cherry-pick), than omit a patch in the quilt patch series. Not sure if it's only me, but this quilt stuff is really messing with my work flow. Please drop your thoughts in here. Best regards, Mihai

x2goclient 3.99.2.0 introduces excessive client logging
by masc 20 May '12

20 May '12

Hello, since updating to 3.99.2.0 on OSX the log database is flooded with x2go.client debug log messages while having a session connected. As a side effect specific operations like opening a new terminal window are slowed down and .asl log files have to be cleared out manually from /private/var/log/asl on a very regular basis. 3.99.1.0-rc2 did not show this behaviour and I cannot find any client side setting to lower the log level. Is it possible to change the client log level? Thank you, Marco

USB forwarding? (esp. @Alex & @Mike)
by Stefan Baur 19 May '12

19 May '12

Hi Devs (esp. Alex and Mike), this topic has popped up before, but it seems no one is really tackling this (or did I just miss the relevant posts?): Forwarding of USB devices from the guest to the host. Our commercial competitors offer solutions to forward, say, a USB card reader to the host, so digital signatures can be performed on a (windows) terminal server. How hard would it be to add this feature to X2Go (especially when working with a Windows client)? Is it a difficult task, or simply a matter of "nobody got around to coding this yet"? -Stefan
