Nomachine changes to closed-source lisence
by Paul van der Vlis 31 Dec '10

31 Dec '10

Hello, Nomachine changes to a closed-source license. German article: http://www.linux-magazin.de/content/view/full/57229 On the Nomachine site: http://www.nomachine.com/news-read.php?idnews=331 Maybe it's good to make a list of organisations who are using it and to plan something together. With regards, Paul van der Vlis. -- http://www.vandervlis.nl/

PyHoca-GUI v0.0.18 released for testing (using Python X2go 0.0.28)
by Mike Gabriel 31 Dec '10

31 Dec '10

Dear list, I have just released another test version (v0.0.18) of PyHoca-GUI (a wxPython X2go client implementation for the systray). Debian (>=squeeze) and Ubuntu (>=lucid) packages are available for installation. Further information can be found here: http://das-netzwerkteam.de/site/?q=node/71 Changes / modifications / improvements since last announced release (v0.0.15): o greatly improved session management (X2goSessionRegistry class) -> which makes it possible to notify more properly about what happens to running/suspended sessions o added/enabled a session profile manager o added edit functionality for connected profiles o added local folder sharing while session is connected o added SSH proxy support (see below) o rudimentarily added XDMCP support (not yet fully working) o added command line option that make PyHoca-GUI portable (esp. interesting for Windows version which will be available soon) o added Xserver support for Windows version The SSH proxy feature: ---------------------- As it was a customer request and also something I need regularly I implemented a SSH proxy server feature into PyHoca-GUI. What it does is this: 1. create a forwarding tunnel to some well protected host via my server: ssh -lmike myserver.local -L 54321:host.reachable-through-VPN.via.myserver:22 2. then connect an X2go session to myserver.local:54321 in order to reach the highly protected server at the end of the above SSH tunnel. SSH proxy support adds for new options to the sessions file: usesshproxy=true|false sshproxyhost=<hostname>:<port> sshproxyuser=<username> sshproxytunnel=<loca_host>:<local_port>:<remote_host>:<remote_port> SSH proxy support, of course, is implemented with Python Paramiko. The SSH proxy settings can be editor for each sesson profile under the ,,Connection'' tab. I have tested configuring SSH proxy quite a lot with PyHoca-GUI and x2goclient-qt. Both apps use the same sessions configuration file and the above options persist well when editing session profiles with either of the GUI applications (PyHoca-GUI known how to interpret them, x2goclient-qt simply ignores them). @Heinz+Alex: I was quite happy to see that x2goclient-qt ignores unknown session options and leaves them also untouched when editing a session profile. PyHoca-GUI also does this with session options it does not know. Thus, it is possible to add session profile options to the sessions (or GCONF or WINREG) file without the clients interfering with each other's ,,special'' options. light+love and happy new year (soon!!!)

documentation fixes
by Florian Effenberger 30 Dec '10

30 Dec '10

Hi, I would recommend some changes to the documentation: - When using a SSH key, the passphrase (at least on Mac) is not stored by the system's SSH agent, but it looks like the key password has to be entered into the password field in x2go. Took me quite a while to figure out. ;-) - For installing the package key on Ubuntu and probably Debian, the following command is easier than the one in the documentation: apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C509840B96F89133 - For adding the apt archive, I recommend using echo "deb http://x2go.obviously-nice.de/deb/ lenny main" >> /etc/apt/sources.list.d/x2go.list instead of adding to sources.list directly.

Mac client can't find X11 sometimes
by Florian Effenberger 30 Dec '10

30 Dec '10

Hello, I have the issue that the Mac client can't find X11 sometimes. X11 is configured accordingly with accept network connections and safe connections, and sometimes it works, but sometimes x2go says it can't connect to X11. Restarting x2go, even logging in and out doesn't help. I tried deleting ~/.x2go and ~/.x2goclient and .Xauthority, to no avail. Only rebooting cured the problem. Maybe the problem lies deeper. Although I installed XQuartz, rebooted the machine so XQuartz is default over X11, and also manually chosen XQuartz in the x2go client, the original Apple X11 client is launched all of the time. Anyone can give me an advice on how to debug the problem? ;) Thanks, Florian

plugin install issues on Windows
by Gerry Reno 27 Dec '10

27 Dec '10

Hope everyone is having nice holidays. I tried installing the Windows plugin (3.01-11) today on a few machines (Windows XP). The 32-bit Windows plugin installs fine but just shows a black screen on every recent Firefox version. What's funny is I've installed this a number of times on Windows XP and it always installed and ran (although with mouse issues). But now, the plugin just gives a black screen. Has anyone figured out the right voodoo to get the plugin installing reliably on Windows? Regards, Gerry

x2gothinclient boot error
by Neil W. Hunt 27 Dec '10

27 Dec '10

Hello, I am attempting to load the x2gothinclient system. I have the client booting from the network via DHCP and starting the x2gothinclient as per the instructions on the website. However upon startup I am getting an error: Begin: Mounting root file system /init: .: line 171: can't open /scripts/NFS [] Kernel panic - not syncing: Attempted to kill init! Any ideas? I have boot=nfs, but is there something else I might be doing wrong?

Need a preseed option in deb files for sudoers entries
by Jeff Hanson 22 Dec '10

22 Dec '10

The preinst scripts in both the x2goserver and x2goprint debs add sudoers entries. When adding the packages to an existing installation this is adequate (although it may violate a Debian packaging policy somewhere). If the packages are installed during a Debian/Ubuntu installation using kickstart and/or preseeding it causes a conflict. The problem is that the entry "%admin ALL=(ALL) ALL" is added after the installation/post-script stage. If x2goserver or x2goprint is installed, their NOPASSWD entries are already in sudoers and the %admin entry overrides them since the file is processed from top to bottom. This causes x2go connections to fail with "sudo: pam_unix(sudo:auth): conversation failed" and "sudo: pam_unix(sudo:auth): auth could not identify password for [user]" errors in auth.log (an infinite number as it really doesn't want to give up until I kill x2gostartagent). Preseed options/templates need to be added to these debs so that the sudoers entries can be skipped via preseed/debconf and added later by a late_command script or manually after installation.

X2GO and SSH
by --[ UxBoD ]-- 22 Dec '10

22 Dec '10

Hi, would you have any details on how you compiled OpenSSH for Windows please ? We are experiencing an issue we believe may be due to the age of the distributed SSH client and would like to update it to the latest release. -- Thanks, Phil

git repository status, cloneurl?
by snalwuer＠cip.informatik.uni-erlangen.de 20 Dec '10

20 Dec '10

Hello, Sorry if I'm bugging you with this... I'm interested in changing some code in x2go and of course commiting those changes back. Because it would make things easier, I would like to ask about the state of the official git repository? Is there a 'git-clone'-able official tree somewhere I can base my changes on? Greetings, Alexander Wuerstlein.

Re: [X2go-dev] x2go with likewise-open (ldap) questions
by Neil W. Hunt 20 Dec '10

20 Dec '10

Ivan, Thanks, I really appreciate your suggestions. ********************* >Please, provide more information about all versions that you use. For >example, I'm using X2goclient 3.01-13 under Windows7 as client, because the >latest version 3.01-14 doesn't work. I am using 3.01-08 for Ubuntu as client. This is the one that downloads by default from the debian library. I have also tried it with 3.01-04 for Windows and for Mac, but same results. I will try 3.03-13 and see if there are any differences, but I doubt it. ********************** >1. Change your ssh logging by changing inside file: /etc/ssh/sshd_config - >LogLevel INFO change to LogLevel DEBUG3 >Then watch the authentication log: tail -f /var/log/auth.log .And login again >(I know that you said that it authenticate successfully, still check this out) I changed this and now have more info. I still cannot see any differences in the login messages between the two messages. I tried attaching each log file, but the list said I needed approval to send something with attachments of 200K. ******************* >2. Login locally on the Ubuntu server with: USERNAME@DOMAIN (although you >can't see them through gdm or kdm), if you can successfully login to the >domain locally. If you have troubles with that, then the problem is with >likewise. BTW, are you using likewise-open? How you've configured it? Using >domainjoin-gui? Can you see from System -> Administration -> Active >Directory Membership. (You can see that with Local user of Ubuntu). I can login locally as a LW user no problem, it shows the full gdm desktop. I am using Likewise-Open 6.0 and joined using domainjoin-gui ******************* >3. Try to login with SSH client (like putty for windows) using again >USERNAME@DOMAIN, and the password. Then check if this login is successful. Have done this as well and there are no issues, perfectly successful login as a LW user. ***************** >4. If authentication is good, but there is blank/black screen, then try >another: OS, Client, Client version. As I said above, the latest version >doesn't work in my scenario. Hint: Don't try to connect with client from the >same server, as it is not possible. If you use Windows, try to find other >OS, install other (virtual if possible) Windows, Linux, whatever is easy for >you. Again, I have tried it with clients on Linux, Mac, Windows, all the same result: full GDM desktop with audio for local accounts, blank screen (but all successful messages in the log) for LW/LDAP users. ************************ BTW, as I'm fearing that if/when I get this issue resolved with the black screen showing up, that I will then have the audio problems, I will add these comments: -I have Likewise Open setup to connect to our domain as the Default Domain, thus all of our uid's do not use the format DOMAIN\user. Before, we all used these IDs, but since we currently only have one domain, I have set LW to use the default domain and so now we can login with just "user". This also affects our directories and thus my .x2go sessions look like: /home/local/DOMAIN/nwhunt/.x2go/C-nwhunt-51-1292422868_stDGNOME_dp32 rather than /home/local/DOMAIN/nwhunt/.x2go/C-DOMAIN\nwhunt-51-1292422868_stDGNOME_dp32 And within that directory are indeed the pulse audio files you mentioned were NOT there when you included the ~/.x2go/C-DOMAIN\userid-.... .pulse-client.conf .pulse-cookie I will report back if I find anything more.
