SSH agent forwarding with X2Go client
by Walid MOGHRABI 16 Jun '16

16 Jun '16

Hi, I know this has been asked long ago before but it seems there is still no SSH agent forwarding with X2Go client (I know it exists with PyHOCA but I prefer using X2Go client). Is it planned ? This would be a very interesting feature since I would prefer avoiding deploying my users private keys on their remote machine so that they can hop on other machines without password authentication (espacially with our gitlab server). I know there is a way to workaround this with the SSH proxy feature but that doesn't work well with Windows and my users are running X2Go client under Windows. Best regards.

no local sound with x2go
by looper＠gmx.li 14 Jun '16

14 Jun '16

I use X2Go with Debian Linux Wheezy (server version: 4.1.0.0-0x2go1.1~git20160225.1310+wheezy.heuler.1, client version: 4.0.5.2-0x2go1~git20160504.1196+wheezy.heuler.1). All packages from X2go repository (http://packages.x2go.org/debian) It works fine, but I can't hear the sound local, it comes everytime on remote machine (on the x2go server). All settings are default, no changes. Is there anything I forgot do to? I tried this with Debian to Debian machines and with windows (7, x64) client to Debian server, same result. Thanks a lot for your help! Greets, Peter

x2go stopped working, how do I debug this?
by M.Rule 11 Jun '16

11 Jun '16

We recently moved a server to a new network and x2go is not longer working. The x2go client crashes too quickly to view or copy the error messages that occur before it fails. On the server side, I can see these messages in this in auth.log. I've replaced all possible identifying information (hopefully) with bash-style variable substituions (e.g. $USER). I apologize as this reduces clarity, but I don't want any identifiable details on record. $DATE $TIME $HOSTNAME sshd[14538]: reverse mapping checking getaddrinfo for $INTERNET_PROVIDER [$INTERNET_PROVIDER_IP] failed - POSSIBLE BREAK-IN ATTEMPT! $DATE $TIME $HOSTNAME sshd[14538]: Accepted publickey for $USER from $INTERNET_PROVIDER_IP port 49488 ssh2: RSA $A_RSA_KEY $DATE $TIME $HOSTNAME sshd[14538]: pam_unix(sshd:session): session opened for user $USER by (uid=0) $DATE $TIME $HOSTNAME systemd-logind[1544]: New session 10 of user $USER. $DATE $TIME $HOSTNAME su[15451]: Successful su for $USER by root $DATE $TIME $HOSTNAME su[15451]: + ??? root:$USER $DATE $TIME $HOSTNAME su[15451]: pam_unix(su:session): session opened for user $USER by (uid=0) $DATE $TIME $HOSTNAME systemd-logind[1544]: New session c20 of user $USER. $DATE $TIME $HOSTNAME su[15451]: pam_unix(su:session): session closed for user $USER $DATE $TIME $HOSTNAME su[15468]: Successful su for $USER by root $DATE $TIME $HOSTNAME su[15468]: + ??? root:$USER $DATE $TIME $HOSTNAME su[15468]: pam_unix(su:session): session opened for user $USER by (uid=0) $DATE $TIME $HOSTNAME systemd-logind[1544]: Removed session c20. $DATE $TIME $HOSTNAME systemd-logind[1544]: New session c21 of user $USER. $DATE $TIME $HOSTNAME sshd[14538]: pam_unix(sshd:session): session closed for user $USER $DATE $TIME $HOSTNAME su[15468]: pam_unix(su:session): session closed for user $USER $DATE 17:04:56 $HOSTNAME systemd-logind[1544]: Removed session c21. $DATE 17:05:01 $HOSTNAME systemd-logind[1544]: Removed session 10. I'm not really familiar with things like this, but it looks like it is repeatedly creating new sessions, and then these sessions are closed (for some reason). I don't understand form these messages. On the client side, this is as much of the log as I can get before the program crashes. I haven't been able to locate the x2go client logfiles .

I need more detailed errors if I'm going to solve this on my own -- I can't really access all the error messages, nor interpret the errors available, at the moment. Thanks in advance if you're able to help. Best, M. Rule.

Want to set the Display number in X2GO client
by Roy Chowdhury, Subho 08 Jun '16

08 Jun '16

Hi, I am new to x2go and for a testing I need to export the display of a centOS docker onto the x2go client. However, I am facing the issue is the Display number in the x2go client is changing as we connect onto the docker host IP with the specified username and password. So the DISPLAY variable set for the x2go server in the docker doesn't match with that of the x2go client and hence, it is giving the error "Error: cannot open display:". Can someone suggest me what I am doing wrong here or if there is any way by which we can set the display number to a specified value for a certain user or if we can make use of some other tool. Thanks & Regards, Subho

X2Go TCE problem
by Popung 08 Jun '16

08 Jun '16

Hello list, I use http://wiki.x2go.org/doku.php/wiki:advanced:tce:install as my guide to install X2Go TCE on: - Linux Mint 17.3 MATE x86-64 as X2Go Server, and - Debian 7.90 as PXE server (both are VMWare VM). Booting my thinclient I got boot menu: X2Go Thin Client Environment - Boot from local harddrive - X2Go Thin Client - memtest86+ (run memory test) Press [Tab] to edit options When I choose "X2Go Thin Client", it just only showing text mode login as below: Debian GNU/Linux 7 x2gothinclient tty1 x2gothinclient login: _ Do I possibly missed something in my config?

X2go on a tablet - options?
by Steve Gaarder 07 Jun '16

07 Jun '16

I want to travel light and still be able to connect "back home" via x2go if something needs my attention. I will be carrying an Android tablet, so it would be great if I could use that (along with an external mouse & keyboard). I see several options, but no clear indication of which is best: 1. Android with the work-in-progress client 2. Get a dual-boot tablet (Android/Win 10) and use x2go under Windows 10 3. Dual-boot with Android & Linux and run x2go under Linux I don't need sound or file sharing or printing, but I do need the setup to be reliable. Has anyone tried this? Has it worked for you? thanks, Steve Gaarder System Administrator, Dept of Mathematics Cornell University, Ithaca, NY, USA gaarder(a)math.cornell.edu

fresh install - debian sid
by Frank Freese 06 Jun '16

06 Jun '16

Hi, as I had some problems (all sessions were killed on logout instead of pause and resume) with my years-old x2go-server I decided to purge x2go*. But: on debian SID 64 I cannot install x2go again. The reason are dependancy problems with nxagent. Any hints? Thank you in advance, Frank

Cannot share a Windows folder
by Nicolau Werneck 01 Jun '16

01 Jun '16

Hi. We have x2go running in our servers here, and sharing folders from windows have been working fine for me. One day --- perhaps after a few reboots --- it stopped working. From the x2go client I get no information. On the server I can only see this in /var/log/messages /usr/bin/x2gomountdirs[41899]: WARNING: insertion of /cygdrive/C/Users/N213A~1.WER/MYX2GO~1 failed (already mounted?), not mounting My ~/media/disk/_cygdrive_C_Users_XYZXYZXYZ/ is just empty. Any thoughts? How can I debug this? We do have another mount going, for the windows network shares at ~/media/disk/_cygdrive_/h/, that eventually works. It does take some time to run and I would also like to know how to make it faster... Thanks, ++nic

Xfce4 and kioskrc on Centos 7.2
by Laurent Pouilloux 25 May '16

25 May '16

Hello x2go users, I'm quite new in administrating x2go and I'm trying to prevent users to shutdown/reboot/suspend/hibernate the system with XFCE 4.12. In a regular environment, one can enable kiosk mode by creating the file /etc/xdg/xfce4/kiosk/kioskrc and put in : [xfce4-session] CustomizeSplash=NONE CustomizeChooser=NONE CustomizeLogout=NONE CustomizeCompatibility=NONE Shutdown=NONE CustomizeSecurity=NONE However, it seems that xfce4 desktop bindings are not supported by x2go http://wiki.x2go.org/doku.php/wiki:advanced:desktopbindings and indeed when I log out I still have all the buttons available. Is there any trick to make it work ? Via polkit ? Or should I think to switch to a supported desktop environment (mate, lxde) ? Thanks for any answer.
