How to dynamically resize the session display ?
by Christophe Lohr 30 Aug '13

30 Aug '13

Hi, I'm trying x2go to be connected on an GNOME desktop. The gnome-control-center tool allows us to dynamically change the resolution of the remote desktop. This immediately resizes the window of the x2go viewer. Unfortunately, this causes strange effects regarding the gnome desktop: the taskbar and the menu bar are truncated, dialog boxes are no more centered, etc. It is as if information about the new resolution were not propagated to gnome. Is there a better way to do that? (Is it a bug regarding the implementation of xrandr?) PS: It has nothing to do, but I've seen that x2goclient has an "maximize" option. Unfortunately this affect only the window of the session manager. It would be nice if the window of x2goagent could also be maximized (and not only fullscreen or at custom resolution). Isn't it? Best regards Christophe

No connection to remote proxy with x2gothinclient
by Frank Wittemeier 29 Aug '13

29 Aug '13

Hi, i setup a X2go Server on Kubuntu 12.04 with x2gothinclient enviroment. I can connect to the server from my notebook with Kubuntu 13.04 and X2goClient, it woks fine. But i have a problem with the thinclients. They boot and the X2go client starts. I can select a session an enter username and password. Then i get this error: Could not yet establish the connection to the remote proxy. Do you want to terminate the current session? Yes / No Both options bring me back to the same error message. What's my mistake?

Re: [X2Go-User] Login via ~/.ssh/authorized_keys fails
by Matthias Kauer 28 Aug '13

Hi Mike, thanks for the confirmation and the submission. If anyone is interested, one thing I did for now, to address this issue was to allow password-based access from my LAN addresses as described here: http://askubuntu.com/questions/101670/how-can-i-allow-ssh-password-authenti… (Note that the match block should be at the end of sshd_config file as it affects all statements below it if I understand it correctly) Use a |Match| block in |/etc/ssh/sshd_config|. |PasswordAuthentication no Match address 192.0.2.0/24 PasswordAuthentication yes | Best, Matthias PS: Is there a comfortable way to reply to individual messages from the digest email that doesn't involve plenty of copy &paste + praying that it will be sorted correctly like just now? Probably no, right?

Error running x2go client on Mac

Downtime code.x2go.org
by Mike Gabriel 28 Aug '13

Hi, the system hosting the Virtual Hosts (httpd) code.x2go.org packages.x2go.org has a short downtime atm. One hard drive feels buggy, so I do a reboot on the whole virtual hosting server followed by some test and maybe eventually a replacement of the buggy hard drive.

Hi, I am looking for input on how to set up an ssh key-based authentication. I generated an RSA key pair with puttygen and added it to ~/.ssh/authorized_keys2 => confirmed that I can login with putty. Now, I specify the same private key in x2goclient (windows). I enter my password and I am then prompted for the password of the ssh key. I enter it and the same ssh key password prompt reappears. This seems to be an infinite loop. When I cancel it, I get a message saying that only publickey is supported as login method (which corresponds to my sshd_config settings). I then tried renaming ~/.ssh/authorized_keys and using a DSA key pair. putty still works as expected with both of these alternatives. x2goclient still shows the same problems however. It only lets me login if I adapt my sshd_config and authenticate via user / password combination. Is this a known limitation? What is the best way to achieve high security? Can I limit the x2go connections to only LAN IPs (without restricting the pure ssh connections)? Best Wishes, Matthias Kauer

Re: [X2Go-User] X2Go-User Digest, Vol 36, Issue 13

Hi Mike, I'm glad to help. A really cool tool like X2go deserves a really great documentation. I am always amazed how few people (especially here in the Westcoast of the US) don't know X2go. I have been using it for a long time now, but might be a little shaky in the internals. What I am good at though is seeing both the developers side and the users side and be able to bridge it in documentation. One thing that I would think would work great is to have an into page in the wiki, called "New to X2go? Start here! What is X2go and what does it do?" I would write a little thing there about how Linux was basically always the perfect Terminal server, BUT no easy free framework ever existed to use it. That we used to envy RDP on Windows and that we now got the same thing and much better on Linux. I especially want to point out what it can do (like thinclient support which is super cool). On some details I might have to ask you a few things, what what is, since I have seen that you added a ton of new features that I am not even aware what they do (I for example never used the desktopsharing function) I would also like to do a bit there where I do a little FAQ like: I got X11 forwarding over ssh, why do I need X2go? (A think I hear all the time from people) and point out what it can do more.

Hi Mike, First I'd like to thank you for all the great work and effort you have put into X2go. I would like to contribute to the project. My skill is not necessarily programming, but I think I might be able to improve some of the documentation, a thing that you might not have time to. Or is there another way I can contribute my time? Thanks, Markus

Redirect only specific sound devices?
by Buddy Butterfly 24 Aug '13

24 Aug '13

Hi all, for a headless system I am trying to run a headset locally on it. For operation I have used x2go which works perfect, even for sound. So this solved the headache with KVM ;-). Now I would like to use a headset locally on the headless system which is connected via USB and its own usb sound card (Logitech, works always perfect!). I am unable to get the headset to work while being connected to via x2go. Headset should be primarily for voip. So, how I could use this headset? Is it possible to configure somehwere that not all sound devices should be redirected but only specific ones? With this I could try to leave out the headset sound card. Thanks for any help, Matt
