Question about Pyhoca-gui
by Paul van der Vlis 20 Sep '11

20 Sep '11

Hello, To use Pyhoca-GUI you need 4 steps: - start Pyhoca-GUI, what only adds an icon - find and open the icon - connect to a server - start a session to that server I think for many normal people this is "complex". They would like 2 steps: - start the program, so that it's visable and not only an icon - start a connection and session to a server I am afraid this is not possible with Pyhoca GUI. Correct? What's the advantage to have a separate connection and session? With regards, Paul. -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl

x2goclient does not connect, Pyhoca-GUI does.
by Paul van der Vlis 20 Sep '11

20 Sep '11

Hello, Strange problem. I connect with x2goclient to a customer, it says after a very short time: "Access denied. Authentication that can continue: publickey,keyboard-interactive". When I connect using SSH with the same username and pasword and as the same user, there is no problem to connect. I've also tried Pyhoca-GUI. That worked without problems too. Can somebody explain me what's the underlaying difference? Maybe some different library is used for DNS or something like that? When I try it with x2goclient using a wrong password, there is nothing in the /var/log/auth.log on the not-working-host. When I connect to another customer with x2goclient, there is no problem. When I use a wrong password there, it is logged in /var/log/auth.log. With regards, Paul -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl

pyhoca-gui, x2goclient compatibility bugfix released
by Mike Gabriel 14 Sep '11

14 Sep '11

Hi all, today I have discovered and fixed a bug in pyhoca-gui that caused session profile problems in x2goclient after pyhoca-gui had been started on the same system for the same user (on Linux, both use the same config file: ~/.x2goclient/sessions). The symptoms were: o start pyhoca-gui o edit a session profile, change it from some desktop command to a non-desktop command o switch it back to a desktop command again o in pyhoca-gui you won't realize a problem o but: if you use this session profile in x2goclient, a desktop session will start in non-desktop mode: many individual windows are opened for the different desktop applications and applets I have just uploaded pyhoca-gui 0.1.0.8, which fixes this compatibility problem. The new pyhoca-gui version will also repair session profiles: edit a broken profile and save it again (from within pyhoca-gui). The session profile should be usable in x2goclient again, then.

SOLVED X Connection Refused problem
by John A. Sullivan III 07 Sep '11

07 Sep '11

Hello, all. We've seen a couple of postings in the past where users just could not connect and would get session errors about the X connection failing with a 111 Connection Refused and a message about channels with certain file descriptors and IDs not being closed. We've hit this in the past and have never gotten around it reliably. Any success seemed to be purely random luck. Today, we cracked one definitively. The problem was a mangled /tmp/.X11-unix directory. It is very specific to our environment but it may jog someone else's mind to find what the ultimate underlying issue is. We have been working on creating portable, encrypted boot sticks to boot a lightweight Linux desktop to connect to our X2Go systems as a way of getting around the poor performance of the Windows X2Go client as well as provide extra security, lower end user support requirements, further separation between the data center based "Content Network" and the unmanaged end devices, and portability between physical computers. All the testing and builds were done with the same very old laptop with Debian Squeeze. The only differences was one boot stick was built by installing Debian from the netinstall CD and used LXDE and the other was built with debootstrap and used Xfce. In both cases, we had a script named settmp to move the /tmp directory into RAM if there was sufficient RAM in the machine. It did this by copying anything already in /tmp to a scratch directory, deleting everything in /tmp, remounting /tmp as a tmpfs, copying everything back in, and then erasing the contents of the scratch directory. File transfers were done with rsync to ensure easier and safer handling of hidden files (no rm -Rf /tmp/.* - which deletes /tmp/.. ! - thankfully did not learn that the hard way). The LXDE system ran x2goclient perfectly well but the Xfce system almost never connected. Suspecting it was an SSH problem because of the channel error messages, I tried doing an ssh -X to the x2goserver and running xterm. It complained about a connection refused and pointed to .X11-unix which I remembered was in /tmp. I wondered if the moving and then moving back was mangling it. I then restarted X on the same system now that /tmp was already moved and x2goclient worked perfectly. I then rewrote the script as a real init script and used insserv to place it before x11-common. After several reboots, it has worked flawlessly. x2goclient connects all the time. In retrospect, I had comment out the settmp script on the LXDE station while troubleshooting something else and had forgotten about it! So, we successfully solved the dreaded X connection refused problem in our environment. Hopefully that will help the others who have been burned by it - John

x2goserver on SLES11
by uhaller＠kabelbw.de 06 Sep '11

06 Sep '11

Hi, I found your posts within the x2go wiki, thank you very much for providing the instructions for manual install from source tarballs. I would also like to switch from freenx to x2go, therefore I want to install the x2goserver on an SLES11 installation. I followed the instructions and completed setting up x2goserver on SLES11. Now I'm trying to connect to x2goserver via an x2goclient (X2Go Client V. 3.99.0.0 (Qt - 4.7.2)) on Ubuntu 11.04. When starting the session I'm getting following problem: "Authentication failed" - "Access denied. Authentication that can continue: publickey,keyboard-interactive" I'm able to connect via ssh. Do you have any ideas what might be wrong? It is possible to get more detailed information via special trace settings? Thanks in advance, Uwe.

On the x2go-user ML there is a discussion going on about margins and X2go printing. Do we want to look at that more closely???

Problems setting print system in x2go
by Mario OROZ 01 Sep '11

01 Sep '11

Hello, I'm new to the list. I use a server x2go on a Debian 6.0 with Windows XP clients. I do not understand how to set the printing to print on printers on the client side. I installed cups-x2go, and created a printer with cups cups-driver that provides x2go. I installed cups-x2go, and created a printer using the driver that provides cups-x2go. On the client windows, menu Option / Settings / Printing tab is checked the "Show this dialog Before start printing" Can anyone tell me of some howto or explain how to configure the local client printing from the server windows x2go Already, thanks

question regarding x2goclient armel builds
by Jimmy Knowles 31 Aug '11

31 Aug '11

Thanks for your work on the x2go packages. I was hoping someone could help me to be able to connect using the armel builds. I have a hp touchpad with x server running and a chrooted version of debian squeeze. I've installed the packages without any problems and I'm having some problems getting a session to start successfully. When I initiate a session from the touchpad, it will connect and the desktop displays, but any window manager items seem to crash. The panels don't display, any pop-up windows just flash and flicker. Only the desktop icons display correctly. And dmesg gives the following errors repeatedly: [65102.522642] metacity[5959]: segfault at 0 ip 00007f5d5e4e1ea1 sp 00007ffffb4ba480 error 4 in libXrender.so.1.3.0[7f5d5e4dd000+9000] [65102.523278] gnome-panel[5960]: segfault at 0 ip 00007fca77ca7ea1 sp 00007fff08238000 error 4 in libXrender.so.1.3.0[7fca77ca3000+9000] [65102.720377] trashapplet[5968]: segfault at 0 ip 00007fdb87f6fea1 sp 00007ffff313ec10 error 4 in libXrender.so.1.3.0[7fdb87f6b000+9000] [65103.621171] gnome-panel[5981]: segfault at 0 ip 00007f0211630ea1 sp 00007fffe7b2b790 error 4 in libXrender.so.1.3.0[7f021162c000+9000] [65103.622815] wnck-applet[5966]: segfault at 0 ip 00007fe8dac6eea1 sp 00007fffca25a130 error 4 in libXrender.so.1.3.0[7fe8dac6a000+9000] [65103.891078] metacity[5980]: segfault at 0 ip 00007f43eec66ea1 sp 00007fffff4193c0 error 4 in libXrender.so.1.3.0[7f43eec62000+9000] .

One difference that I notice is that the windows-initiated session name ends with dp32 (I'm assuming that's the color depth?) and the touchpad/armel-initiated session ends with dp24. Any ideas on how to get it to work correctly when initiating the session on the armel device? The server is running ubuntu natty, with version 3.0.99.5-0~49~natty1 of x2goserver. Thanks, Jimmy

x2goclient armel builds
by brian mullan 31 Aug '11

31 Aug '11

Mike Not sure if you remember but when I was trying to get PyHoca working on a chrooted Ubuntu environment on the nook color tablet I was also getting the RandR error in the logs. Initial authentication would work but before I'd see any remote display it would crash. My environment was an Android tablet, chrooted Ubuntu running LXDE so it was running Ubuntu's x-server at the time.
