Bug#1226: x2goclient for Mac OS immediately throws error regarding "PulseAudio verison number" then crashes
by Sean Hooten 26 May '18

26 May '18

Package: X2GoClient_latest_macosx_10_9 Version: 4.1.0.0 Steps taken to produce the bug: Ran x2goclient.app, immediately get error upon initialization. Exact error message: > Error fetching PulseAudio version number! Unexpected format encountered. Expected: I expected x2goclient to initialize normally without an error message. What actually happened: x2goclient shows me the regular user interface with the pop-up error message. After selecting "Okay" it crashes. This was not an issue before, seemingly began happening spontaneously. I have attempted to reboot my machine, and reinstalled x2goclient and XQuartz to no avail. I have attached the full bug report. I'm not sure why it is attempting to fetch a PulseAudio version number, this is not on my machine and I had not yet attempted to connect to my server before receiving the error. OS: Mac OS X 10.11.6 Thanks! Sean

Bug#1253: ssh broker : bad error feedback in interaction mode
by Walid MOGHRABI 15 May '18

15 May '18

package: x2gobroker-ssh version: 0.0.4.0-0~972~ubuntu16.04.1 priority: bug Using the ssh broker is great because it adds the ability for the x2goclient to interact with the auth mechanism such as PAM so that you get notified that you need to renew a password for example. This is great but it doesn't always work well. For example, the user don't get the reason why the access is denied. Here are different tests I made based on the following setup : x2gobroker in ssh mode with local PAM auth based on Samba Winbind/Kerberos. I tried both situations to compare : * with the x2goclient in broker-ssh mode * with a term rying to connect through SSH 1) Account set for password change with temporary password in Active Directory, user type wrong password (neither old or new one) * with x2goclient: get message "Access denied. Authentication that can continue: publickey,password,keyboard-interactive" * with term : "Your account has been locked. Please contact your System administrator. Password: " 2) Account set for password change with temporary password in Active Directory, user type good password * with x2goclient: get a new password form in order to type (and confirm) the new password. Reseting password works and you get logged in to the broker with the sessions list displayed. However, if you click on the "cancel" button, x2goclient freeze and must be killed, you're not sent back to the login form. On the other hand, if you change your password and then be logged in, clicking on the session slot fails because this is the old password that is relayed to the session slot and not the new one. When it fails, you get a new login form to enter your password again, if you type the new password there, it works. * with term: "Password: ******" "Password expired. You must change it now." "Enter new password: ******" "Enter it again: ******" If you cancel (ctrl+c), nothing happen and you get back to the prompt. If you enter the good old password, you're prompted to change it then you're logged in. If you enter the wrong password, your prompted to retry 2 times then you get this message "Your account has been locked. Please contact your System administrator" (this is our security policy, this is normal behaviour, 2 fauils then blocked for 10mn. 3) Account disabled in Active Directory * with x2goclient: get message "Access denied. Authentication that can continue: publickey,password,keyboard-interactive" * with term : "Your account has been locked. Please contact your System administrator. Password: " Would be great to fix the issues in 2) and would be great to retrieve the error message directly from PAM so that we get the reason.

Bug#1252: ssh broker : load balancing not working
by Walid MOGHRABI 15 May '18

15 May '18

package: x2gobroker-ssh version: 0.0.4.0-0~972~ubuntu16.04.1 priority: bug Hi, Tried using x2gobroker-ssh (0.0.4.0-0~972~ubuntu16.04.1) instead of classical http broker and finaly got it working but in ssh mode, load balancing on my server farm is not working, every session is redirected to the same server (the first one) while it is balanced correctly with the http broker on the same broker server. I would love to send logs but it seems this broker don't produce log files or I couldn't find a way to get them.

Re: [X2Go-Dev] [X2Go-Commits] [x2gothinclient] 01/01: let user choose architecture by setting TC_ARCH variable. Default amd64.
by Mike Gabriel 02 Mar '18

Hi Alex, unless you have proper reason for selection the 4.9.0-4 kernel, I'd rather suggest to pick the generic package e.g. for amd64 https://packages.debian.org/stretch/linux-image-amd64 This pulls in the always newest kernel, which currently is 4.9.0-6 (containing meltdown and spectre fixes, which are not shipped in the -4 kernel).

Bug#1264: x2goclient 4.1.1.1-1 on Plasma 5.12.2-1 could work great with minor fix
by Pascal Billery-Schneider 26 Feb '18

26 Feb '18

Package: x2goclient Version: 4.1.1.-1 Distrib: Archlinux Dear devs, When launching on a client an x2go SHADOW session, x2go can't display properly when compositing effects are enabled on plasma. So the trick is to ssh to the server with the login name of the x2go SHADOW session and to disable kwin compositing effects: $ qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.suspend let the SSH session open After the x2go SHADOW session is done and close... ... simply go back to the server previous SSH session and: $ qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.resume So it would be convenient to have the ability in the x2goclient to set a field before the SHADOW command with: qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.suspend and after: qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.resume Or BTW, there is a toggle trick: if [ `qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.active` = true ]; then qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.suspend; else qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.resume; fi Regards, Sagittarius
