Seahorse via X2Go Custom Desktop: Insufficient Priviliges
by Alexanderstr Miete 02 Nov '19

02 Nov '19

Dear X2go users and team, As it seems there is no easy solution to allow the X2Go session user have the same privileges in Ubuntu (when connecting via: connect with "Custom Desktop" Command: MATE) as a local user (i.e. via VNC) Some issues can be solved via editing settings in /var/lib/polkit-1 , for example to allow the remote user to access Network settings. However, I did not manage to allow Seahorse to show / properly work with passwords when accessed during an X2Go session: When accessing via VNC, network credentials can be edited and stored in Seahorse. With X2Go access via connect with "Custom Desktop" Command: MATE , all these sections seem to be missing in Seahorse even though the same user is used, and Caja (the file manager in Mate) seems to requests a password for SMB access every time. See attached screenshot. Help would be much appreciated. How can Seahorse get the same privileges during that X2Go session as for a local session/VNC? Thanks

X2GoBroker Python3 CentOS 7 issue

Hi, I'm having an issue installing the x2gobroker-agent package on CentOS 7.

Kerberos 5 issue x2go
by High Grandmaster Lord Zeronious 29 Oct '19

29 Oct '19

Hello, I get the following error message (rarely, but when it happens its always on first time login to PC, after shutdown for a while) *Check your GSSAPI configuration or choose another authentication method.* I don't know how to actively recreate this error, and it only happens very rarely (the rest of the time it opens a session to the server and works fine) I'm not sure why it happens/what can be done to fix it. My x2go version: x2goclient_4.1.2.1-0~1788~ubuntu18.04.1_amd64.deb My Ubuntu version: 18.04.3 Latest version

Forwardable GSSAPI / Kerberos from X2Go
by James M. Pulver 29 Oct '19

29 Oct '19

I'm working with trying to use kerberos with our X2Go server from different OSs. We are running a Server 2016 Active Directory with the UNIX attributes. All computers are joined to this AD. On Windows 10, I can get GSSAPI to authenticate and let me log in without a password. However, I cannot then ssh to a different linux computer without doing a kinit. If I check "delegatation of GSSAPI Credentials to the server, I get various cp errors around files with "odd" characters, or unable to find the keyring. On other Scientific Linux 7 computers, I can't even get the Kerberos 5 authentication to work, it just gives me an error to login with my password. This does work with the first remote linux computer via ssh. I have tried enabling delegation in AD for the computer account of my primary jump host, no change I can see. So - why is X2Go different on Linux with regard to using Kerberos 5 auth when straight SSH works, and 2 has anyone figured out the windows equivalent to kinit -F for a user so they can do 2 hops? -- James Pulver CLASSE Computer Group Cornell University

Chrome speed with x2go
by Keith Burns 17 Oct '19

17 Oct '19

Hello, So many things I love about x2go over any other remote desktop solution, and I've pretty much tried them all in one flavour or another. The one thing that is really hurting me though is Chrome / webkit speed. The issue has been discussed here before a long time ago, but I didn't see much by way of resolution. This is now I suspect impacting electron based apps, which are becoming more prolific. Bouncing between my client OS and Linux isn't desirable, and in some cases isn't possible. The Linux desktop is on a 200/20Mb connection with ~20ms or less RTT, which means I get screen updates from the server -> 20Mb -> client as the server is leveraging the upload speed to communicate back to the client. I would imagine that 20Mb is sufficient to handle pretty much any of the encoding settings, so I am happy to try any settings. Server: Ubuntu MATE 18.04, installed using apt packages. (4.1.0.3 ?) Client: OSX 4.1.2.1 I'm a software developer so I am comfortable building from source, administering my own machine, so happy to experiment to try and get, if not resolution, at least a configuration that gets the best performance possible. Cheers Keith.

x2go does not access seahorse's default keyring, so problems in evolution
by D Ducky 13 Oct '19

13 Oct '19

Hello, When I log in to Fedora 30 locally, it prompts me for my keyring password on login, and I type it and then I proceed normally. I then can open evolution and it accesses my credentials fine. However, when connecting to my desktop via x2go, evolution says it failed to obtain access token, credentials, etc, and keeps prompting me for mail passwords and doesn't work. If I open seahorse, it doesn't even list my default keyring. If I use x2godesktopsharing, it works fine, but I can't do that from a laptop because it makes the display too small. Please tell me there is some way to fix this? Thanks,

Re: [X2Go-User] X2go irritating System policy

This worked very well in terms of lag/speed. > Following your reply I changed to "session type "connect to local desktop)" and the permission issue did not appear anymore, however, there was a significant lag when working with the user interface - unusable really. Well, I think I need to clarify something here: a) connecting with "Custom Desktop" will start a NEW session. b) connecting with "local desktop" will _connect_ to the running X-Server (usually :0) which is slower due to the way it works. According to your description it works with type b) but not with a). I think in a session a) type you need to the environment to enable access the type b) session running in parallel. Unfortunately I do not have the environment available to test this in detail. > So it would be great if I could still connect with the more "speedy" option "Custom Desktop" Command: MATE, but solve the privilige issue. > Or do you have another solution? > Thanks > > P.S.: How come X2go does not have a user forum? We have several mailing lists. As we are constantly struggling with (human) resources there are no plans to add a forum. As far as I can see most of the administrating members prefer mailing lists over clumsy web forums anyway.

Every connect from Ubuntu 18.04 client gives core dump
by Kees Bakker 11 Oct '19

11 Oct '19

Hi, The setup is reasonably simple. A network with Ubuntu 18.04 PCs (workstations, so to speak). SSH connections between them work flawlessly. But x2go refuses to work. At all. Whatever I do, I only get Segmentation fault (core dumped) If I run x2goclient in the gdb debugger, it shows that it fails in Thread 6 "SshMasterConnec" received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7fffdf7fe700 (LWP 5778)] 0x00007ffff7b89eeb in ?? () from /usr/lib/x86_64-linux-gnu/libssh.so.4 My first question: is anyone using x2go successfully on Ubuntu 18.04 (client and remote)? -- Kees

No terminal windows, no logout.
by Thomas Stephan 07 Oct '19

07 Oct '19

Hi, we use x2go for multiple users to connect to workstations running Ubuntu 16.04.6 LTS. Clients run on MacOSX or Windows machines. After using the setup for some days with multiple reconnects, for unknown reasons we can no longer open terminal applications via these remote-desktops. This applies to all terminal applications like UXTerm, Xfce Terminal, XTerm, etc. We can still perfectly open a file manager, or e.g. Matlab and work with those. We can also no longer close the session because the confirmation dialog to confirm user logout does not appear. It seems like there is a terminal process started every time we start a terminal via the desktop GUI. But the window does not show up. After rebooting the workstation, everything works fine again, terminals can be opened, logout confirmation dialog pops up. Currently we use XFCE desktop.
