X2go GIT Repo - Patches?
by Moritz Struebe 02 Feb '11

02 Feb '11

Hi Mike, as there now is an "official" git repo. What shall we do with the work we did? There was quite a bit of dependency-cleanup and build fixing involved to get things running at launchpad. Shall we mail the patches to the mailing list or will you pull them from our server? Or do you rather want the patches sent to another mail address? Cheers Morty -- Dipl.-Ing.

SSHFS and Permissions
by --[ UxBoD ]-- 31 Jan '11

31 Jan '11

Hello all, I have been working on making removable media available to Windows via a Samba share and hit a very strange problem. When you initially save a file to the share it would complain about having insufficient permissions, though if you were to save it again straight away it would work. The problem has been tracked down to how the SSHFS is mounted from within x2gomountdirs. The original command was: sshfs -o ServerAliveInterval=300,Cipher=blowfish,IdentityFile=$key,UserKnownHostsFile=$key.ident $user\@$host:\"@dirs[$i]\" \"$mntpath\" -p $port 2>>~/mounts.log for which I have changed it too: sshfs -o uid=$uid -o gid=$gid -o ServerAliveInterval=300,Cipher=blowfish,IdentityFile=$key,UserKnownHostsFile=$key.ident $user\@$host:\"@dirs[$i]\" \"$mntpath\" -p $port 2>>~/mounts.log with those two new variables being set via: my (undef,undef,$uid,$gid) = getpwuid($<); and the resulting mount have the ownership of the users primary id and group. Is there any reason why this approach was not used ? or it worked quite happily as the mount is 777 anyway ? -- Thanks, Phil

X2go client window in rootless mode crashes when mouse is moved over title bar
by Mike Gabriel 31 Jan '11

31 Jan '11

Hi there, this issue has probably been already addressed: During development of PyHoca-GUI I encounter some weird behaviour on mouse moves that cross the title bar of a rootless session window (e.g. xterm via X2go, but also any other app). I think that this problem only occurs with the initial rootless window (e.g. xterm). Any subsequently started application window has not shown this behaviour so far. Yesterday then, I found an article on the NoMachine site that might well relate to the problem: http://www.nomachine.com/ar/view.php?ar_id=AR06H00567 Question at Heinz+Alex: is this referred to functionality part of the x2goagent code? Is it possible to disable it? I could at the x2goagent sources, but my C++ capabilities are to weak to dig through that... Also refer to this posting which points out that the named functionality must be found somewhere in x2goagent: http://www.nomachine.com/fr/view.php?id=FR06D01396 Greets, 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…

Debian packaging of X2go
by Mike Gabriel 30 Jan '11

30 Jan '11

Dear X2go community, for anyone who is interested in Debian packaging of X2go (i.e.: preparing X2go for inclusion in Debian and also all later development around an officially Debianized X2go), these issues / topics will be discussed on this mailing list: pkg-x2go-devel(a)lists.alioth.debian.org You can subscribe to this list under this URL: http://lists.alioth.debian.org/mailman/listinfo/pkg-x2go-devel Hopefully we will welcome many of you on that list... Best, 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…

re Project Management
by brian mullan 28 Jan '11

28 Jan '11

Since there is a discussion on this topic... *Launchpad <https://launchpad.net/>* would seem to be a reasonable fit for hosting the x2go project as there are over 20,000 projects hosted on Launchpad already? Launchpad provides: - *Bug tracking* <https://bugs.launchpad.net/> - *Code hosting* <https://code.launchpad.net/> using Bazaar< http://bazaar.canonical.com/> - *Code reviews* <https://help.launchpad.net/Code/Review> - Ubuntu package building and hosting <https://launchpad.net/ubuntu> - Language Translations <https://translations.launchpad.net/> - *Mailing lists* <https://help.launchpad.net/Teams/MailingLists> - *Answer tracking and FAQs* <https://answers.launchpad.net/> - Specification tracking <https://blueprints.launchpad.net/> Click here for their tour <https://launchpad.net/+tour> I think it would be very suitable for all debian related distro users.

can't start ssh tunnel / integration with existing ldap
by Martin Steigerwald 26 Jan '11

26 Jan '11

Hi! I installed X2goserver one into a Debian Squeeze VM under VMware ESX today. Since we use a LDAP server to central user management I integrated it via libpam-ldap and libnss-ldap manually. We also use NFS for home directory so I added that too. Logging into the server via SSH works as expected. But I get "can't start SSH tunnel" when trying to open a new X2go session with x2goclient. When I use a SSH key I get messages like this: Verbindung fehlgeschlagen intraws.of.teamix.net: Unable to connect: /home/ms/.x2go/ssh/socaskpass-M31562 Unable to connect: /home/ms/.x2go/ssh/socaskpass-M31562 Permission denied, please try again. Unable to connect: /home/ms/.x2go/ssh/socaskpass-M31562 Permission denied, please try again. Unable to connect: /home/ms/.x2go/ssh/socaskpass-M31562 Permission denied (publickey,password). I guess this has to do with the usage of NFS. ~/.x2go/ssh is 750 and root is squashed to nobody:nogroup. Thus it is neither the user nor the group. Since chmod 777 ~/.x2go/ssh fixes key based login for me, it seems that something of x2go server is using root privileges to access files in the home directory of the user. Could this be changed to use user rights - root can su to any ? This would work with NFS. Other questions: 1) Can X2go client be told to use an existing ssh agent which has the right identidy added? A ssh user@intraws works already without asking for the key password, thus if x2goclient uses this ssh-agent it wouldn't need to ask for the passphrase as well. 2) What steps are necessary to integrate x2go with an *existing* LDAP server? x2goldaptools depends on slapd and samba and since we use NFS with an existing LDAP server I want neither of those. LDAP authentification via PAM works already. I can login with SSH and LDAP password of a user. I thought this would be enough for x2go *when* users that use x2go are in the group x2gousers. They are. But in the local group. What additinional steps are necessary? Ciao, -- Martin Steigerwald - team(ix) GmbH - http://www.teamix.de gpg: 19E3 8D42 896F D004 08AC A0CA 1E10 C593 0399 AE90

Re: [X2go-dev] X2Go Client
by Joachim Langenbach 25 Jan '11

25 Jan '11

Good Afternoon, I've created a small patch (Version 3.01-5, don't know which is current version) to integrate the first features of the system tray stuff. Currently this features of the list are supported: * Auto minimize to tray after established the connection successfully * Open the normal client > * Auto minimize to tray after established the connection successfully (and > / or start already minimized?) > * Options right clicking on the tray icon: > * For each active connection: > * Close > * Pause > * Make directory available (In german version it is called "Ordner > freigeben") > * Start a new connection > * Open the normal client The patch includes some commented lines, they can be uncomment to display a standard message on minimize to the tray on first minimization. Therefore the system tray stuff can than be turned on by default (which is propably wanted by most users). Right now, system tray is deactivated and must be enabled at the ConfigDialog. Regards, Joachim Langenbach

x2go not working on ubuntu 10.10
by brian mullan 25 Jan '11

25 Jan '11

As mentioened in a separate email I have EC2 Ubuntu 10.10 servers running x2go and they work fine. I also provided you my phone number. I'm not sure what you are doing wrong or are not doing but what you are trying to do is fairly easy. Send me an email with the AMI # you are using for the EC2 image. I'll take that AMI, start an instance, install x2go server on it and try to log into it myself. Brian ---------- Forwarded message ---------- From: jmm <jagermeistermeister(a)gmail.com> To: x2go-dev(a)lists.berlios.de Date: Fri, 21 Jan 2011 02:31:06 +0100 Subject: [X2go-dev] x2go not working on ubuntu 10.10? Hi, I tried to get this working all night, but it seems there is no way to connect to an ubuntu 10.10 installation using x2go (package x2goserver-home). When trying to connect, x2goagent is complaining about not being able to open a display (in the session log). The machine is an Amazon EC2 instance, which has no video card. I suspect this is causing the trouble. I have read it was working on ubuntu 10.04 by the way, as in http://blog.restbackup.com/how-to-use-amazon-ec2-as-your-desktop I also tried freenx, neatx and nxserver (from nomachine), and they all give similar errors. Tightvncserver on the other hand does work, maybe that's not so useful information, but just in case. The server log says: $ cat session.log /usr/bin/x2goagent: line 1: -e: command not found NXAGENT - Version 3.4.0 Copyright (C) 2001, 2007 NoMachine.
