Different behavior of X2Go Client from Desktop and TCE
by Oleksandr Shneyder 24 May '18

24 May '18

Hi guys, I have a strange issue. The Xinerama works well in full screen mode, when x2goclient is started on desktop, but doesn't work if x2goclient is started from TCE. It's the same version of client: 4.1.2.0-0x2go1~git20180514.1774+9.heuler.1 and same version of Debian - stretch. Session config identical as well. xrandr output inside of X2Go session is different though: desktop: Screen 0: minimum 320 x 240, current 4480 x 1080, maximum 4480 x 1200 NX1 connected 1920x1080+2560+0 0mm x 0mm nx_1920x1080 60.00* NX2 connected 2560x1080+0+0 0mm x 0mm TCE: Screen 0: minimum 320 x 240, current 2560 x 1024, maximum 2560 x 1200 default connected 2560x1024+0+0 0mm x 0mm 1360x768 60.00 320x240 60.00 1024x600 60.00 1280x800 60.00 1600x900 60.00 1600x1200 60.00 Although if session is started from TCE, I'm getting error dialog from /etc/x2go/Xsession.d/20x11-common_process-args: "unsupported number of arguments (3); falling back to default" before I'm starting to look for the reason, maybe someone who tweaked on Xinerama or on x2go server have any idea why it's happening? regards, Alex -- ----------------------------------------------------------- Oleksandr Shneyder | Email: o.shneyder(a)phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Harzstr. 4 | Fax. : 0911 - 14870374 9 D-90491 Nürnberg | Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Bug#1301: ubuntu ppa x2goserver broken
by jkirsz 24 May '18

24 May '18

Package: x2goserver I installed x2goserver and x2goserver-xsession on Ubuntu 16.04 (latest upgrades) and 18.04 (latest upgrades). When i try to connect to those x2goserver with different x2go-client (latest archlinux / windows 10), and open XFCE desktop environment, i get an error "Connexoin Failed : Failed to start X2Go Agent session with ID user-xxxxxxxxx_stDXFCE_dp24. X2go Agent terminated unexpectedly. Aborting session startup."

command to start xfce4
by Dr. K. nick 21 May '18

21 May '18

Dear x2go team, according to x2goserver/bin/x2goruncommand xfce4 is being launched by executing xfce4-session 239 elif [ "$cmd" == "XFCE4" ] || [ "$cmd" == "XFCE" ]; then 240 cmd="/usr/bin/xfce4-session" According to https://docs.xfce.org/xfce/getting-started startxfce4 should be used to start xfce, at least from command line. /Command line// //Use //|startxfce4|//to start an Xfce session or choose //Xfce Session//from the login manager... /So why does x2go uses xfce4-session instead of startxfce4. Is this legacy or are there technical reasons for that? Marcin //

I'd prefer understanding what's going on first. nxagent is running if (nxagentGrabServerInfo.grabstate == SERVER_GRABBED && nxagentGrabServerInfo.client != NULL) { /* * If any client grabbed the server it won't expect screen * configuration changes until it releases the grab.

BUT: If nxagentAdjustRandRXinerama FAILS to get that data it will NOT fall back to the version you see but to reporting ONE screen (called NX1, IIRC). So all this fails somewhere else. Can you run an nxagent that has #define TEST and #define DEBUG enabledin in Screen.c? Uli

Bug#1300: X2Go Client: API for setpass between client and broker
by Mike Gabriel 16 May '18

16 May '18

Package: x2goclient Severity: wishlist Version: 4.1.1.1 Tags: patch X-Debbugs-Cc: o.schneyder(a)phoca-gmbh.de Hi Alex, a customer of mine is paying me to do some work on X2Go Client and X2Go Broker. While doing that, I noticed that the --change-broker-pass option in X2Go Client does not fully work together with the X2Go Session Broker. In fact, I could not find any implementation reference in earlier broker prototypes. I thus came up with some "API" for password setting. When the client sends the setpass task to the broker, it expects an answer (success or failure). I will scan for PASSWORD CHANGED: OK (or something else). Please take a look at the below patch, if it breaks something for your setups. If you have a different "API" for setpass, please let me know and I adapt the patch.

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.

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.
