Bug#957: x2goserver authenticates session but does not start xfce

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Package: x2goserver Version: x2goserver-4.0.1.19-3.el7.x86_64 1.

When i connect from my workplace (debian stable) the hostkey is stored and then the session is closed. I have the same behaviour, when i connect from a windows client. I have both clients configured to start xfce that is installed on the server. When i use mobaxterm (with its own xserver) on Windows, i can call 'startxfce4' successfully. When i start it on my debian workplace, it fails because i have xfce running locally. Because the x2goclient window closes so fast, i can not read the last lines. One thing that might help: The server is running a Java Application from HP (SSMP). This Java Server binds to the IPV6 Interface of the server. That made me disable the complete IPV6 Config of the server. As result i had to set 'Addressfamily inet' in the sshd config to make X11 tunneling over ssh work. kind regards - -- Hans-Joachim Hoetger "Zwei Dinge sind schädlich für jeden, der die Stufen des Glücks will ersteigen; Schweigen, wenn Zeit ist zu reden, und Reden, wenn Zeit ist zu schweigen."

Bug#765: Kex Error in X2Go client
by rpr nospam 08 Oct '15

08 Oct '15

Hi! I also saw this issue while trying to connect with X2Go Client for Windows (v. 4.0.5.0) to x2goserver (v. 4.0.1.19-0~1064~ubuntu14.04.1) on a Linux Mint 17 machine. The connection worked fine until the SSH server on the Linux machine was reconfigured in order to harden it (see the recommendations in https://stribika.github.io/2015/01/04/secure-secure-shell.html) That reconfiguration allowed only the following host keys and key exchange algorithms: HostKey /etc/ssh/ssh_host_ed25519_key HostKey /etc/ssh/ssh_host_rsa_key KexAlgorithms curve25519-sha256(a)libssh.org,diffie-hellman-group-exchange-sha256 The Elliptic Curve Digital Signature Algorithm (ECDSA) (and the corresponding /etc/ssh/ssh_host_ecdsa_key) is not enabled because its implementation may use a faulty pseudo-random number generator (i.e. containing a back door created by NSA) as explained in some pages referred by the aforementioned article. After some investigation I found how to get rid of the error: in C:\Users\username\ssh\known_hosts remove the line corresponding to the x2goserver host and ecdsa-sha2-nistp256 key exchange algorithm: x2goserver_host_address ecdsa-sha2-nistp256 ... -- rpr.

Bug#955: x2gosid sanitizer check in x2gosqlitewrapper.pl / x2goserver-4.0.1.19-1.1.x86_64 rpm for opensuse 13.2
by Frank Knoben 07 Oct '15

07 Oct '15

Package: x2goserver Version: 4.0.1.19-1.1 File: x2gosqlitewrapper.pl Subroutine: sanitizer Operating System: openSuSE 13.2 64bit Hello, on my system, there are a lot of users, whose username consists of only numbers. In the latest x2goserver rpm for my opensuse 13.2 system (x2goserver-4.0.1.19-1.1.x86_64) there seem's to be something wrong with the sanitzer check function in x2gosqlitewrapper.pl. For the users, whose username contains only numbers, I get the error message of a malformed session id. When I don't do a sanitzer check on the x2gosid, everything is fine. Unfortunately, I have not learned the perl programming language and I'm not so good with regular expression, that I do know how to fix the problem correctly. For me, I just put a return $string; after the elsif ($type eq "x2gosid") { and everything works fine for me again. Sincerly Frank Knoben

Bug#112:
by Bryan Berndt 06 Oct '15

06 Oct '15

Seems I’ve come across a similar bug. I can use x2go to connect to a Fedora 22 workstation running XFCE. While using the small keayboard on my iMac, and using a large Apple keayboard and the built in macbook pro keyboard, everything works fine. Keys work as expected, for the most part. While in the XFCE session, I fire up VirtualBox running a Windows 7 VM. Trying to use this, is where my keyboard no longer works at all. Looks like the same mappings as in post #47. Am unsure how to proceed to work around. May just end up using VirtualBox built in remote connection for access to it. Bryan Berndt bryanb(a)bryanb.net

debian jessie general protection trap in libNX_X11.so.6.2 caused by some apps
by Jean-Francois Dagenais 02 Oct '15

02 Oct '15

Hi all! Long time x2go user. Just remade my box with debian jessie. Followed the server instructions steps. I can run xterm and other programs, but some (like gnome-terminal, xfce-terminal, mate-terminal ... and others) cause x2goagent to crash with: traps: x2goagent[8626] general protection ip:7fdf1317fe6d sp:7ffe79b7dd70 error:0 in libNX_X11.so.6.2[7fdf13133000+123000] This is using today's nightly build. Wondering how to proceed now. Sources build to get more debug information? FYI, I am a general software and linux kernel developer but am not familiar with the x2go project development. Thanks!

Bug#953: x2goclient does not pick up the nb_NO translation
by Klaus Ade Johnstad 01 Oct '15

01 Oct '15

Package: x2goclient Version: 4.0.5.0-0x2go1+git20150728.1112+jessie.main.1 When running x2goclient on a machine configured with the local nb_no, I would expect the x2goclient gui to be in nb_NO also, since it's translated, but instead the gui is in Danish. When starting x2goclient from cli, this is the output I get: klaus@dhcp388:~$ x2goclient x2go-INFO-1> "Starting X2Go Client..." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/x2goclient_nb_NO" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/x2goclient_nb" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/x2goclient_no_NO" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/x2goclient_no" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/x2goclient_nn_NO" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/x2goclient_nn" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-INFO-4> "Translator: :/i18n/x2goclient_da found." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/qt_nb_NO" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/qt_nb" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/qt_no_NO" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/qt_no" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/qt_nn_NO" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-WARNING-1> "Non-fatal: can't load translator: :/i18n/qt_nn" x2go-WARNING-1> "Trying to load language with lower preference, if existent." x2go-INFO-4> "Oversætter::/i18n/qt_da found." x2go-INFO-3> "Started X2Go Client." x2go-INFO-6> "Closing X2Go Client ..." x2go-INFO-7> "Finished X2Go Client closing hooks."
