Bug#169: Usability: Too easy to start a session by clicking anywhere in the profile box
by Dan Halbert 29 Jun '14

29 Jun '14

Package: x2goclient Version: 4.0.0.3 It's a little too easy to start a session in the X2Go client window. A click anywhere in a profile box (it's sort of a gian button) will start a session, unless one clicks on one of the narrow setting lines or the lower right-hand pull-down-menu triangle. If I'm aiming for one of those spots but miss, a session starts. I'd rather not have the whole profile box sensitive like that. A "Connect" button or icon would be a little safer. I also remember the first time I tried to use X2GoClient, I was surprised there was no "Connect" button, and had to guess that a click on the profile box would start a session.

Help with X11 errors
by Michael DePaulo 24 Jun '14

24 Jun '14

At work, at least 1 other user and myself are getting errors like these in ~/.xsession-x2go-errors every several days. We are using IceWM (command: icewm-session) on Ubuntu 12.04 32-bit with most of the bugfix updates installed for ubuntu itself. We are using the x2go stable PPA and we have installed all the updates available for it. For legacy reasons, our default shell is TCSH. xgoserver-xsession is installed. These errors might not be causing an actual problem, but the other user reported that x2goclient got randomly disconnected yesterday. Furthermore, she could not reconnect to her session; she had to terminate it and then start a new one. That's why I am looking into them. XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":51"^M after 110 requests (110 known processed) with 0 events remaining.^M XIO: fatal IO error 104 (Connection reset by peer) on X server ":51"^M after 804237 requests (804236 known processed) with 6 events remaining.^M xterm: fatal IO error 11 (Resource temporarily unavailable) or KillClient on X server ":51"^M XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":51"^M after 123 requests (123 known processed) with 0 events remaining.^M icewmbg: Can't open display: :51.

Bug#206: When a user ends pyhoca-gui, the session cannot be resumed
by Dick Kniep 15 Jun '14

15 Jun '14

package: pyhoca-gui Severity: normal Version: 0.4.0.1 When a user ends pyhoca-gui by right-clicking on the icon and selecting "exit", the application exits OK, however when a session is still active, that session cannot be resumed. What happens is that when one restarts pyhoca-gui and that connection, pyhoca-gui indicates that it will resume the session, however, nothing happens and the session is quietly killed. Met vriendelijke groet, Dick Kniep Lindix BV tel. 036-5215580 mob. 06-50991858

Bug#364: Please add config option to disable bubble help text and change the wording of it
by Stefan Baur 07 Jun '14

07 Jun '14

Package: x2goclient Severity: wishlist Version: 4.0.1.2 Upon connection, an info bubble pops up, containing a *totally cryptic session name* and disappearing after five seconds or so. No non-technical user can make use of that message, seriously. And even technical users will have a hard time memorizing a cryptic session name within 5 seconds. Please, also add an option to disable this popup, and seriously consider changing the displayed info to something more user friendly like "Connection to host <host>, session <sessionname> established as user <user>." It's okay to add the cryptic string somewhere where techies can find it if they need it, maybe in an About-Box or so, but please - think of the chil^W ordinary non-technical end user. And again, I'm kind of disappointed that we're adding silly eye candy when there still are serious bugs to fix.

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
