by Paul Menzel 08 Sep '09

08 Sep '09

Dear list,i dependency based boot sequence was enabled by default in Debian sid/unstable a few days ago [1]. The X2go init-scripts do not seem to have any LSB tags. insserv: warning: script 'K20x2goserver' missing LSB tags and overrides Is anyone able to add those headers and submit a patch?

install problems solved

hello, we had problems to install x2go: we made a big mistake * we comment the lo interface, it was so silly that we don't see this mistake long time: the result was that the machine work, but the next boot, it was no nfs ... now it is going well. as i told you before i think, it will be better to make a install script, because you can control if it's really work. the documentation has mistakes and for the installer they can be sure, they don't make a tipping / copy mistake. we have done such a script and we can give to the community, if desired. now we have tried to make x2go as a xen virtual machine. it is at the moment not working, we get following mistake something like: in login (without ldap): cannot connecting to host "localhost:30001" proxy with nmap 192.168.0.250 we dont have port 30001 open tcpdump on eth1 where is the dhcpserver try from the client to reach the x2go server / 13:27:03.666347 IP 192.168.0.106.3088888606 > x2goserver.planetexpress.de.nfs: 116 getattr [|nfs] 13:27:03.679034 IP x2goserver.planetexpress.de.nfs > 192.168.0.106.3088888606: reply ok 116 getattr [|nfs] 13:27:03.666594 IP 192.168.0.106.930 > x2goserver.planetexpress.de.nfs: . ack 1669475119 win 41915 <nop,nop,timestamp 274543 293666> 13:27:03.668053 IP 192.168.0.106.3105665822 > x2goserver.planetexpress.de.nfs: 116 getattr [|nfs] 13:27:03.668130 IP 192.168.0.106.3122443038 > x2goserver.planetexpress.de.nfs: 116 getattr [|nfs] 13:27:03.668161 IP x2goserver.planetexpress.de.nfs > 192.168.0.106.3105665822: reply ok 116 getattr [|nfs] 13:27:03.668218 IP x2goserver.planetexpress.de.nfs > 192.168.0.106.3122443038: reply ok 116 getattr [|nfs] 13:27:03.668424 IP 192.168.0.106.3139220254 > x2goserver.planetexpress.de.nfs: 116 getattr [|nfs] 13:27:03.668471 IP x2goserver.planetexpress.de.nfs > 192.168.0.106.3139220254: reply ok 116 getattr [|nfs]/ some idea, where is the mistake? michel

17 Aug '09

Hello, I was looking for a bug-tracker for X2go and I found this: https://developer.berlios.de/support/index.php And I did put some bugs and a feature requests in it. But now I am not sure anymore ;-) Is this some kind of a bug-tracker, or is it something else? Is it in use? With regards, Paul van der Vlis. -- http://www.vandervlis.nl/

Fonts to big or to small
by Paul van der Vlis 17 Aug '09

17 Aug '09

Hello, I still have the problem that my fonts are sometimes to big or to small in the X2go session. Even with the newest client and server. I found this article about this problem: http://www.nomachine.com/ar/view.php?ar_id=AR04C00198 And this seems to be true. In the x2go session I see 75x75 dots per inch, and in my normal session I see 96x96 dots per inch. I used "xdpyinfo | grep resolution" to get this info. In the article they have a link to a solution, they say to use a variable: DEFAULT_X_DPI = "96", but this is for the Nomachine software, not for X2go. I had the same problem in FreeNX. There I found a solution. In the configfile I found this: -------- # Extra options sent to the different nx agents. See !M documentation # for examples of useful parameters. AGENT_EXTRA_OPTIONS_X="-nolisten tcp" -------- I've changed this to: AGENT_EXTRA_OPTIONS_X="-nolisten tcp -dpi 96" And now my DPI-porblems are gone in FreeNX. But this does not help for X2go. Is it possible to give agent-options for X2go? Or do I need to hack /usr/bin/x2gostartagent? With regards, Paul van der Vlis. -- http://www.vandervlis.nl/

Password in plain text!?!?!?
by Alexander.Kuchler＠pruftechnik.com 04 Aug '09

04 Aug '09

Dear group, today I figured out you are saving the password entered during the startup of the session in plain text in C:\Documents\%User%\.x2go\ssh\. And not even delete it after closing the session.. You can not be serious!? Especially when knowing you are promoting X2Go for schools etc. where different people might access the same terminals this is not only dangerous but breakneck. Yours, Alexander

install : at least 4 mistakes in pdf de.insstallation.x2go.pdf and a install script
by kamerun＠immerda.ch 04 Aug '09

04 Aug '09

hello, at least and after many test, we are able to install x2go installation date monday 3.8.2009 installation on machine with debian 5 and lxde (ths same result with a debian 5 machine with gnome) we have done the installtion many times on different machines with the same bad result we can start client and everything is ok after the installation, when reboot, *big problem:* when booting stop in statd (NFS) and follow after ~ 1 minutes after stop y postgres : long message CEST FATAL could not create any TCP/IP sokets after more than 1 minute continue stop again by statd wait long and finish until login after login nfs does not work atftp is running dhcp is running but the file /etc/default/dhcp3-server is overwritten nfs cannot start, postgres has mistakes and it takes very long time to boot it comes to login and we can login, but no postgres and nfs is running. i try to start nfs but it fails, so logically the client cannot start and the machine by shutdown the machine don't shutdown properly we try to start nfs and posstgres manually, but it fails: no socket i wonder if somebody else has the same situation *installation: * from my humble opinion there are at least 4 mistakes in the pdf de.installation.x2go.pdf #echo "192.168.1.1 x2goserver.planetexpress.de x2goserver" >>/opt/ x2gothinclient/etc/hosts -- label linux kernel vmlinuz append root=/dev/nfs nfsroot=192.168.1.1:/opt/x2gothinclient ro initrd=initrd.img ip=dhcp -- option domain-name "planetexpress.de"; option domain-name-servers 192.168.1.1; # x2go thin client range/group subnet 192.168.0.0 netmask 255.255.255.0 { range 192.168.0.100 192.168.0.199; filename "/pxelinux.0"; next-server 192.168.0.250; } when i put the dhcp-server on 192.168.0..250 and change the ip 192.168.1.1 to 192.168.0.250, it works. it is for me a mistake first not to say on which ip address the dhcp server must be set, that it works the description of de.installation.x2go.pdf. anyway with the 192.168.1.1 i could not install an x2go. there is another mistake : # cd /usr/lib/X2go/scrip # ./x2gocreatebase.sh X2go directory does not exist, it exist x2go directory (i don't know, but i was thinking that before it was existing) question: when i want to close a client, it comes back to login it can just switch off, is it normal? a good news is that lxde is working well, i prefer the light lxde than kde. thanks michel

Problems with the GTK-client
by Paul van der Vlis 31 Jul '09

31 Jul '09

Hello, I have some problems with the GTK-client. The KDE client works fine, and the GTK client does work fine as another user on the same machine. I have purged and reinstalled the gtk-client and I removed the config-data with: gconftool-2 --recursive-unset /apps/x2goclient (as the user where the problems are). But it does not help. When I try to start a session everything works fine, I only see no session. When I start the client again, I can see a running session, I cannot kill that session with the GTK client, but I can kill that session with the KDE client. I don't know how to fix this problem. I will add the complete information from the file .xsessionerrors. The interesting part (I think) is: -------- debug1: Local forwarding listening on 127.0.0.1 port 30049. bind: Address already in use debug1: Local forwarding listening on ::1 port 30049. bind: Address already in use channel_setup_fwd_listener: cannot listen to port: 30049 Could not request local forwarding. debug1: Requesting no-more-sessions(a)openssh.com -------- With regards, Paul van der Vlis.

Problems after installing x2go 3.01
by Paul van der Vlis 31 Jul '09

31 Jul '09

Hello, I installed x2go 3.01 (a beta) with dates from 16-22 juli. First everything worked fine and some bugs where gone, like the keyboard-bug. I installed "x2goserver-home" too. But now x2go does not work anymore. I cannot get a connection. Maybe it was after I executed by mistake this script: /usr/bin/x2gostartagent. I rebooted the machine, the problem is not gone. It is difficult to copy some of the error-messages of the KDE-client because they are gone very fast, but I saw this kind of things while connecting to localhost: Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Thu Jul 30 09:48:31 2009'. Session: Session terminated at 'Thu Jul 30 09:48:31 2009'. or: Info: Using ZLIB data compression 1/1/32. Info: Using ZLIB stream compression 4/4. Info: No suitable cache file found. Info: Forwarding X11 connections to display ':0.0'. Session: Session started at 'Thu Jul 30 09:51:00 2009'. Warning: Protocol mismatch or no X authentication data. or: (...) reaching a usable state. Info: This can be due to the local X server refusing access to the client. Info: Please check authorization provided by the remote X application. Session: Session terminated at 'Thu Jul 30 09:53:13 2009'. When I connect from a laptop with the GTK-client I get an error: cat /home/paul/.x2go/C-.../cmdoutput file does not excist. Is there a better way to get the log? Is there a way to let the server log? Maybe it is important to tell that I have a multiseat X setup here, but before x2go did work without problem. (A multseat setup is a computer what can be used by more then one person. In my situation there are 2 monitors, 2 keyboards, 2 mouses. You can configure it in gdm.conf and xorg.conf.) With regards, Paul van der Vlis. -- http://www.vandervlis.nl/
