Trying x2gokdrive again
by Neal Becker 23 Oct '23

23 Oct '23

I'm trying out Orion's packages of kdrive on F38 client: x2goclient-4.1.2.3-1.fc38.x86_64 x2gokdriveclient-0.0.0.1-2.fc38.x86_64 server: x2goserver-common-4.1.0.4-1.fc38.noarch x2goagent-4.1.0.4-1.fc38.x86_64 x2goserver-xsession-4.1.0.4-1.fc38.noarch x2goserver-4.1.0.4-1.fc38.x86_64 x2goserver-x2gokdrive-4.1.0.4-1.fc38.x86_64 Running kde on both client and server, so far working well. One bug: The command to start kde is no longer startkde, it's startplasma-x11.

AdminByRequest on X2go
by Jeff Thomas 20 Oct '23

20 Oct '23

Hello,I have installed AdminByRequest on Ubuntu 22.04. It works on the local machine. If a user attempts to do something that requires Admin privileges they will receive a popup that requires them to request admin privileges. Once they request it the popup disappears and rights are granted for the remainder of their session. (ABR logs the activity) For the few remote X2go users if they try to do something that requires Admin privileges they will see a message that ABR blocked it, but they do not get the popup to request it. ABR is looking at the issue, but I suspect they will say it is not intended to use on remote session, where multiple people may be signed in at a time... Though we only have a few remote users. Im hoping there may be a way to get the xcfe gui on x2go to display the ABR popup. Any advice would be greatly appreciated! ThanksJT

Fwd: x2go and ssh-agent forwarding

-------- Forwarded Message -------- Subject: x2go and ssh-agent forwarding Date: Thu, 19 Oct 2023 21:21:48 +0100 From: graeme vetterlein <graeme(a)vetterlein.com> To: x2go-user(a)lists.x2go.org Anybody know if this is still current? https://wiki.x2go.org/doku.php/doc:howto:ssh-agent-workaround It suggests a patch was available in 2017 I can see a fresh ssh-agent(1) is getting started (so blocking access to the original client one) also I note the use of /-oClearAllForwardings on the ssh call x2go makes ..... neither look like good news :-( / I did try (XFCE) : xfconf-query -c xfce4-session -p /startup/ssh-agent/enabled -n -t bool -s false xfconf-query -c xfce4-session -p /startup/ssh-agent/type -n -t string -s ssh-agent And indeed the ssh-agnet was not started, but SSH_AUTH_SOCK (to tmp/ssh-xxxxxx/agent.PID [ literally PID not a number ] FYI I need to use the keys to access github and I don't want to put them on the machine I'm x2going into. BTW. I also ran a test using a "custom desktop" of /usr/bin/lxterminal ...and in that terminal SSH_AUTH_SOCK was set to a non-existant filename(socket) in ~/.x2go -- Graeme

Debian resume does not work anymore after update to 4.1.0.6
by richard lucassen 14 Oct '23

14 Oct '23

Client and server "Debian Testing" This morning I got server version 4.1.0.6 using apt. When connecting using client 4.1.2.3-1 it works, but after a resume the client says that the session is still running so the only way to get back to the server is to terminate the session and to create a new one. I downgraded the server to 4.1.0.3-7+deb12u1 and resuming works again. I run a command x environment: /usr/bin/ssh-agent /usr/bin/wmaker I'm at 1000km away from the server and as I use x2go all the time, so I won't be able for the moment to run some tests. Just FYI for the moment. I put these packages on hold: # apt-mark hold libx2go-config-perl libx2go-log-perl libx2go-server-db-perl libx2go-server-perl libx2go-utils-perl x2goserver x2goserver-common x2goserver-extensions x2goserver-x2goagent x2goserver-xsession in order to stay with version 4.1.0.3-7+deb12u1.

Complaints about windows resizing/moved on session resume
by Orion Poplawski 09 Oct '23

09 Oct '23

Many of our users are complaining about: something in the EL8/X2Go/KDE? interface now just runs roughshod over the windows you have open, between suspending and resuming sessions. Windows are re-sided, moved, opened, closed...at random. I often have multiple windows open and, for example, running IDL or editing or something, and I have them placed where I want as I am testing and debugging or writing code, I suspend / restore the session and come back to just randomly placed, sized, opened or closed desktop. **i don't like people mucking with my desktop** whether real or virtual!!! The three of us mentioned to each other that we feel like we are continually re-sizing, finding, and just spending time counteracting what has been done to our setups. So, what's going on what what can be done to stop it? Clients and server are EL8. Desktop environment is KDE. We have a mix of x2goagent and x2gokdrive sessions. We've removed kscreen. Any help would be greatly appreciated. Thanks. -- Orion Poplawski IT Systems Manager 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

build X2GoServer as a user (without sudo) ?
by Elmar Melcher 27 Sep '23

27 Sep '23

Hi, the instructions in https://wiki.x2go.org/doku.php/wiki:development:build-howto-linux:x2goserver require sudo. Is it possible to build and install x2goserver without sudo rights? It would be ok and expected that such a x2goserver would be usable only by the user who installed it into his /home directory, for example under ~/.local/ Regards, Elmar
