Bug#68: X2goclient & OTP
by Pascal Vibet - ADACIS 07 Jun '14

07 Jun '14

Package: x2goclient Version: lucid - precise: amd64/i386 (ppa.launchpad), precise 3.99.0.5-1: amd64/i386 I should use OTM authentification (One Time Password) like google authentificator on my X2go server but it's impossible to mount shared folder and/or local printer. If i don't use OTP, i can see x2goclient connect twice to my server. First time to login and second time, to shared folder and/or local printer Dec 1 10:33:22 my_serveur sshd[22271]: Accepted password for pascal from AAA.BBB.CCC.DDD port 36053 ssh2 Dec 1 10:33:22 my_serveur sshd[22271]: pam_unix(sshd:session): session opened for user pascal by (uid=0) Dec 1 10:33:36 my_serveur sshd[22707]: Accepted password for pascal from AAA.BBB.CCC.DDD port 36057 ssh2 Dec 1 10:33:36 my_serveur sshd[22707]: pam_unix(sshd:session): session opened for user pascal by (uid=0) I i use OTP, password is valide one time. So, i can login on x2goserver but i can not reuse the same password to shared folder: Dec 1 10:37:26 my_serveur sshd[28415]: Accepted password for pascal from AAA.BBB.CCC.DDD port 36062 ssh2 Dec 1 10:37:26 my_serveur sshd[28415]: pam_unix(sshd:session): session opened for user pascal by (uid=0) Dec 1 10:37:36 my_serveur sshd(pam_google_authenticator)[28839]: Trying to reuse a previously used time-based code.

The second connection reuse first one and it can connect whithout authentification. In my test, X2goclient don't use some ssh client option. Regards Pascal Vibet

Bug#42: GNOME3 desktop (in non-fullscreen mode) does XRandR resizing of the desktop session window
by Mike Gabriel 16 May '14

16 May '14

Package: x2gognomebindings Severity: important Version: 2.0.1.6 When a GNOME3 desktop is opened via X2Go in non-fullscreen mode the GNOME3 xrandr / monitor settings code does some awful resizing of the desktop session window. Reproduce (GNOME3, also an issue with Unity): o you need a client-side display greater than 1024x768 o set desktop size to 1024x768 in x2goclient session profile settings o set desktop session to GNOME on a Debian wheezy server o launch session Compare to KDE4: o you need a client-side display greater than 1024x768 o set desktop size to 1024x768 in x2goclient session profile settings o set desktop session to KDE on a Debian wheezy server o launch session What you see: o with KDE4 the desktop session window will have the expected size o with GNOME3 the window appears in the expected size and then gets resized from inside the starting up GNOME3 session o in my case: GNOME3 tries to resize to 1920x1200 pixel. The windows gets adapted to the greatest size possible on my client display (i.e. the window maximizes) o However, the desktop shell inside the window does not adapt to the window size o I can manually resize the window afterwards via the client-side window manager (play with your mouse on the window borders...) o Still, the desktop shell inside does not adapt its size This might well be a GNOME3 bug (detection of X server resize events), but it normally won't cause problems on physical hardware. So, the X2Go team may have to discover a GNOME3 patch for this problem.

Bug#349: Tag: patch
by marcoandredinis＠gmail.com 31 Mar '14

31 Mar '14

Package: x2goclient Version: 4.0.1.1 This email was sent to x2go-dev mailling list, but since it also refers a Bug, I am also filling a bug report Hi I'm developing a program that will use X2Go software. I dont want users to notice they are using any other program besides my own. I have two problems right now: A) X2GoClient Using SHADOW mode with "--hide" does not work. The interface waits for selection of Display (usually ":0") and, since there's no input from user (there's no window) the program does not show anything. There are possible ways of fixing/improving this situation: -allow user to set the default display on sessions' file -create one flag and run program like these: "x2goclient --hide --sessionid=xxx --select-first-display" Anyway, i modified the code of x2goclient/onmainwindow.cpp and added these lines: l4348:..if( shadowSession ) l4349:....slotShadowSess(); Compiled the program, and now i can run "./x2goclient --hide --sessionid=xxx" and the window will show up. This is NOT a fix, this is a nasty workaround. It wontn show the list even when the "hide" flag is not present. B) X2GoDesktopSharing Just the icon on SystemTray. If we could pass a flag like "--no-icon" would be great I could do these simple changes on my own, but i rather see this changes on the official code. Thanks, Marco Dinis

Bug#229: x2goclient for windows unable to use https broker-urls
by Anders Bruun Olsen 27 Feb '14

27 Feb '14

Package: x2goclient Version: 4.0.1.0-pre2 and 4.0.0.3 Platform: Windows I can login to our broker with x2goclient just fine on OSX and Linux, using our externally available https-server. On Windows however, it just fails authentication when using our https-server. It works fine when the broker-url is an http-address. I do not have a build-system for Windows at hand, so I am unable to test newest git revision on Windows. -- Anders Bruun Olsen It-ansvarlig Det Danske Sprog- og Litteraturselskab (Society for Danish Language and Literature)
