Errors starting gnome-session
by Moritz Schuepp 26 Oct '09

26 Oct '09

hi, i'm new to x2go. i am using x2goserver-one on debian lenny server with a gnome-desktop. i receive the following errors in x2goclient when connecting using x2goclient-gtk or x2goclient-qt4: "Cant read host rsa key:/etc/ssh/ssh_host_rsa_key.pub" though the file is readable: -rw-r--r-- 1 root root 393 2009-10-23 10:43 /etc/ssh/ssh_host_rsa_key.pub After that the following error pops up: "Unable to read : .pub" Anyone an idea on that? Thanks! Moritz

arbitrary no-connection issues with »Warning: No data received from remote proxy within 30 seconds.«
by Paul Menzel 23 Oct '09

23 Oct '09

Dear X2go developers and users, since some time I sometimes cannot connect with my client to the server. The system the server is running on gets also used as a desktop machine. I think the issue is surfaces when a second user logs into the system using for example GNOME’s switch-user-applet. I do not know when this problem started. I am using Debian unstable/sid. A big change was the upgrade to GNOME 2.28 and the X.org server (1:7.4 +4). When the problem occurs `nxproxy -S` $ nxproxy -S NXPROXY - Version 3.3.0 Copyright (C) 2001, 2007 NoMachine. See http://www.nomachine.com/ for more information. Info: Proxy running in client mode with pid '4871'. Session: Starting session at 'Tue Oct 6 23:40:59 2009'.

I do not where know where I can get useful server logs for you.

Re: [X2go-dev] x2goclient hangs on login

Hi, so let me see if I got this right now. The users which are in /etc/group have to be in the LDAP tree as well to guarantee that X2go works right? Well Im sorry but im pretty new with LDAP and so I have just added my users with "adduser user x2gousers" like it is described in the manual. I would really love to try X2GO out with LDAP support to have the full functionality, especially the Thinclient things. Basically I have just done what´s in the manual without giving a [LDAPMASTER URI] in the genconf Script and creatings the certificates. I have no idea how to check that LDAP is working correctly.

Please make sure - on server side - that the user who should be able to log in is part of the posix group x2gousers. You also should make sure, that you have an entry inside your /etc/sudoers file looking like this: %x2gousers ALL=(ALL) NOPASSWD: /usr/bin/x2gopgwrapper If you get an error running the command /usr/bin/x2gopgwrapper as the use you wan't to login, something obove is wrong.

Hi, so I think I have found at least one of the reasons why it's not working. I have just recognized that I have 62336 E-Mails in /var/mail :). Every single on with the following text: Subject: *** SECURITY information for GSN-EDU.GSN2 *** From: root <root(a)gsn-edu.gsn2> GSN-EDU.GSN2 : Okt 9 13:28:58 : root : user NOT in sudoers ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot GSN-EDU So what do I missed??

x2goclient hangs on login
by Sauron99＠gmx.de 21 Oct '09

Hello list, this is my very first post to this list and Im quite sure a few will follow ;). Anyway I have a Problem with the configuration of X2goserver. Im finished with the LDAP stuff and so on and want to try it out now. But for some reason after logging in with the X2goclient it hangs right after clicking on "Ok". On serverside some processes starting up but nothing happens... I haven´t complete the PXE, ATFTPD and DHCP stuff and so on but the normal connect via x2goclient should work, right? Do I have to add the clients that are able to connect to X2GO somewhere first?? Greetings -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

Hi, ok I have added a picture of my processes to this mail. I hope that this is ok. Yes maybe its an LDAP related thing.. I will have a look into the logs later today and will report it soon.

Hello Paul, even if the "pg" in the name shows the origen, the use of this operation is to drop broken sessions out of the database. This is done with pg dbs and sqlite. It's clear that you can run x2goserver without this cleaning, as long as you don't have broken sessions.

Our libs are installed in /usr/lib/x2go, so they don't mix up with the QTNX libs. Of cause it would be a good idea to change this to fit to the debian rules. NXagent would be necessary only for x2goserver. We made some changes to NXagent so it can be used with our x2goclient on Maemo.

Hi, Since Im new here, I will at first present myself. My name is Xavier Oswald, Im a debian developer living in Strasbourg - France, and I will help getting x2go in debian. I met Heinz last weekend during a debian-edu meeting and we get out what need to be done to be able to have x2go to debian, starting by the command line client and then going step by step with the others x2go tools. Feel free to ask me to have a look if you think an x2go module is ready or anything you want to know for having a good upstream - debian package match. Greetings, -- ,''`.| ====== Xavier Oswald ====== | mail: xoswald(a)debian.org | : :' :| Engineer at CALDERA GRAPHICS | http://www.caldera.eu | `. `' | GNU/LINUX Debian Developer | http://debian.org | `- | Isaac Project Developer | http://isaacproject.u-strasbg.fr |
