[PATCH] Make sure the socket used by nxagent is not already in use
by Moritz Struebe 30 Jan '12

30 Jan '12

Hi there, this did cost us some pains, because a sshd was using port 6050, so even reinstalling x2goserver didn't solve any issues. This is a pretty hackish solution and maybe someone with a little more bash experience could take a look. Cheers Morty -- Dipl.-Ing.

x2goserver installs into /usr/lib on x86_64 system
by Oliver Burger 29 Jan '12

29 Jan '12

Hi there, after I finally got nx to build on Mageia, I'm now working on x2goserver. I already had to patch the Makefiles because of a few problems: - they try to install several files directly into /etc - they try to set owner and group to root Since you don't build rpm packages as root, that doesn't work. When I'm done, I will send you my patches so you can look into them. But now to my real problem: There's quite a list of files installed into /usr/lib instead of /usr/lib64, where they should be located. Now the question is, will it break anything, when I patch the Makefiles to install them into the correct dir?

Fwd: Performance with KDE 4.8 + Qt 4.8
by Mike Gabriel 28 Jan '12

28 Jan '12

Hi Alex, I guess, we have to take care of this in X2Go, too. What do you think? Mike ----- Weitergeleitete Nachricht von fcoiffie(a)gmail.com ----- Datum: Mon, 16 Jan 2012 15:41:05 +0100 Von: Frédéric COIFFIER <fcoiffie(a)gmail.com> Antwort an: User Support for FreeNX Server and kNX Client <freenx-knx(a)kde.org> Betreff: [FreeNX-kNX] Performance with KDE 4.8 + Qt 4.8 An: freenx-knx(a)kde.org Since first versions of Qt 4, the performance of this toolkit through NX/FreeNX has decreased (compared to Qt3) : it slows to refresh and there are many glitches. Moreover, Qt 4 can supports different graphic backend : - native which uses X11 - raster which makes many operations on an internal graphic buffer without using X11. On a local machine, raster performs well but it is really slow with a remote X11 or NX/FreeNX. It seems that the next version of KDE 4.8 (associated with Qt 4.8) will select raster by default. I have found a workaround to keep raster on a local connection and to select native with FreeNX (ugly hack) : /usr/bin/nxnode : sess_id="$SERVER_NAME-$display-$uniqueid" [ "$EXPORT_SESSIONID" = "1" ] && export NXSESSIONID="$sess_id" + export QT_GRAPHICSSYSTEM=native OLD_UMASK=$(umask) Regards, Frederic ________________________________________________________________ Were you helped on this list with your FreeNX problem?

RPMs for RH6
by Bogdan-Andrei Taru 28 Jan '12

28 Jan '12

Hello everyone, I'm fairly new to x2go, but I'm trying to package X2Go Client & Server for RedHat6 and I have the following suggestion/problem: Server: it's hard to package the X2GO Server as RPM because some paths (/etc/x2go) are hardcoded into the Makefiles and a "make PREFIX=/path install" still installs the files under /etc/x2go. Could anyone please change the Makefile so that the PREFIX option works? Client: in order to compile the client I downloaded the libssh-0.5.0-1 and libssh-devel-0.5.0-1 as RPMs and installed them (it's the same library as Debian's libssh-4, just a newer Version -- the one from Debian Squeeze is the version 0.4.5-3). The client basically works, but segfaults sometimes (not always) in "exception" cases, for example false authentication to the X2GO server. Here's a snippet from a X2GO Session, first it works all right, then I disconnect and start again with a false password: ------------------------------------------------------------------------------------------------------------------------------------ search proxy win: "X2GO-btaru-55-1326987931_stDGNOME_dp24" search proxy win: "X2GO-btaru-55-1326987931_stDGNOME_dp24" "Info: Using shared memory parameters 1/2048K.

Question regarding command line options / portable mode
by newsgroups.mail2＠stefanbaur.de 27 Jan '12

27 Jan '12

Hi List, since I can't find anything in the Wiki nor in the man pages of the linux x2goclient: Is there a place where I can find documentation regarding the command line options of x2goclient (especially the Microsoft Windows version)? I noticed there's an option --portable, which seems to store the session configuration in a "sessions" text file, just like the linux version does by default (the MS Windows default is to store it in the registry). Is there any way to influence where this sessions file is stored, or a way to import a sessions file into the registry? Will x2goclient crash if this file is read-only? (I'm thinking of storing it on a network share that is read-only) That would make a mass roll-out so much easier. Also, does the Windows x2goclient *installer* offer any options that allow an automated roll-out, something like /default (install to default locations with all the default options) and /quiet (do not present any pop-ups, just install)? Kind Regards, Stefan

NX (redistributed) -- x2goagent fully integrated into NX-libs (call for testing)
by Mike Gabriel 27 Jan '12

27 Jan '12

Hi all, recently there has been some noise about X2Go re-working its NX code base. Indeed some quite interesting things have been going on recently around NX and X2Go. During the last weeks we have completely reworked the way we build NX libraries. This has fixed a lot of instability problems people had recently (summer/autumn 2011) already. During this last week we set up the X2Go subproject ,,NX (redistributed)'' (aka nx-libs.git on http://git.x2go.org) The X2Go project's developers (esp. Mike and Reinhard, supported by Alex and Heinz) have decided to re-distribute NX sources as one big tarball that builds with GNU make and contains patches not accepted by NoMachine themselves. The building of the tarball with GNU make already works fine, the ,,make install'' still needs more work. John Williams has agreed to contribute on that (thanks for that!!!). @John: please note that I have uploaded a new tarball containing the functionality described below ;-): http://code.x2go.org/releases/source/nx-libs/nx-libs_3.5.0.5-full.tar.gz During the last days now, we have achieved something that so far has hardly been imaginable (at least to me). We have incorporated three patches into nx-libs.git that allows to turn NX's nxagent into x2goagent during runtime: 01: http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=debian/patches/200_nxage… 02: http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=debian/patches/201_nxage… 03: http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=debian/patches/999_nxage… X2Go's agent is now part of NX and is maintained in nx-libs.git on http://git.x2go.org. The x2goagent package from now on depends on nxagent (as they are one). The x2goagent package provides a symbolic link to nxagent, a separate x2goagent man page and a wrapper script in /usr/bin, nothing else. If nxagent is executed unter the name of x2goagent, the X2GO branding gets activated within nxagent. Also: ,,NX (redistributed)'' is fully FreeNX compliant. Install ,,NX (redistributed)'' from the X2Go package archives and add FreeNX (Ubuntu Launchpad) on top of that. FreeNX and X2Go can now again be installed parallely on the same system. Interesting for migrations or client diversity. This step also allows us to finally abandon the following source projects completely now: nxcomp.git nxcompext.git nxcompshad.git nxproxy.git x2goagent.git See also at the bottom of this page: http://code.x2go.org/gitweb As this is esp. a call-out for testing the new packages(!!!!) here are some short infos on upgrading your X2Go test servers. Packages are available for Debian squeeze, wheezy, sid and Ubuntu lucid, ..., precise. The .deb packages are already available in the X2Go nightly-built repositories: http://wiki.x2go.org/wiki:development:nightly-builds?&#nightly-builds_for_u… Please note, that x2goagent will not install when running ,,apt-get upgrade''. Either you have to run ,,apt-get dist-upgrade'' or explicitly install x2goagent with ,,apt-get install x2goagent''. light+love Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

postinst-script x2goserver
by Jochen Schulz 26 Jan '12

26 Jan '12

Hi! the postinstallation script for the x2goserver (ubuntu) has the following problem: it checks if /var/lib/x2go/x2go_sessions exists, and if not, calls x2godbadmin --createdb. This is not good, because it sometimes breaks upgrades of the package when using a remote postgresql: The postgresdb is configured and accessible but there is no /var/lib/x2go/x2go_sessions because it isn't needed. Then when you upgrade, it calls x2godbadmin --createdb and overwrites the remote postgres-sql-db.. I think it should test if postgres is used, and if so, should never do anything on its own with the db. Users who use the postgres-db anyhow know what they are doing and could do some steps more.
