X2Go Client suddenly failing to connect
by Ivan Gomez 29 Mar '18

29 Mar '18

Dear all, I have been using X2Go client in the current environment for quite a while now without issues. Seemingly all of sudden today an outage happened where X2Go will no longer launch any applications. The connection seems to succeed in the backend: [cid:image001.png@01D3C558.EB0F51C0] However, the client closes the connection before anything happens. Running the client with the debug terminal shows these messages: [cid:image002.png@01D3C559.58693F10] I've validated that I can SSH to the server using other tools and start the X11 applications from command line directly. Any guidance or pointers to figure out why X2Go stopped working would be greatly appreciated. Thank you, Ivan G.

line editing not enabled, Connection Failed (Xiki)
by Karl A. Woelfer 27 Mar '18

27 Mar '18

We have a user who is unable to launch X2go, receiving the following errors: Conection Failed ~/Xiki/bin/.xsh line (...) bind : warning : line editing not enabled Is this maybe a known conflict between key mappings ? I am not very familiar with the Xiki shell. Are there any workarounds people can offer? Thanks for your collective expertise, - Karl

x2go stops working on some Ubuntu 14.04 boxes
by Qianqian Fang 26 Mar '18

26 Mar '18

Dear list, I run a small cluster for my lab, including about 12 Linux boxes running Ubuntu 14.04 (1x with 16.04). We have been using x2go and ssh as the primary tool to access these computing resources. Recently (started a month ago), I noticed there were package updates of x2go server (now 4.1.0.0-0-1517), client (now 4.1.1.1-0-1719) and the nx11 libraries, on the other hand, I started having difficulty log on to some of my servers, and this list starts to grow. I am not sure if this was the result of the recent package upgrade, or the reason motivated the package updates, but I started seeing the below two types of messages: For some of the machines, I saw the below message initially: *The remote proxy closed the connection while negotiating* ** *the session. This may be due to the wrong authentication* ** *credentials passed to the server.* for some other servers, I am getting the below message: *Connection failed.**Failed to start X2Go Agent session with ID account-xxxxxx_stDXFCE_dp24. X2Go Agent terminated unexpectedly. Aborting session startup. * The 1st message appeared first, after I tried to restart x2goserver or rebooting the machine, or apply the updates, deleting the ~/.x2go folder, or a reboot, those machines typically display the 2nd message; none of those were fixed using the above procedures. right now, I have about 2/3 of the my servers are not accessible via x2go. I would like to know if there is a workaround. thanks Qianqian

integrated X-Server and AltGr/right Alt key [now with attachment]
by Joachim Hartmann 26 Mar '18

26 Mar '18

Hello, I come from the Windows world and run a Debian server (jessie) without a graphical interface (no X server installed), keyboard and screen. Operation is normally via putty from the windows7-PC (German QWERTZU keyboard). On the Linux console all characters of the third level (AltGr or right Alt key) are displayed correctly! If I call xterm via x2go-Client (V. 1.1.1) the AltGr key has no effect! - The automatic keyboard recognition is activated at the client! - The files $HOME/.Xmodmap-x2go and $HOME/.Xkbmap-x2go do not exist on the server. The result of @09:56:57#~# xmodmap -pke keycode 8 = Mode_switch NoSymbol Mode_switch keycode 9 = Escape NoSymbol Escape keycode 10 = 1 exclam 1 exclam onesuperior exclamdown onesuperior keycode 11 = 2 quotedbl 2 quotedbl twosuperior oneeighth twosuperior keycode 12 = 3 section 3 section threesuperior sterling threesuperior keycode 13 = 4 dollar 4 dollar onequarter currency onequarter keycode 14 = 5 percent 5 percent onehalf threeeighths onehalf keycode 15 = 6 ampersand 6 ampersand notsign fiveeighths notsign keycode 16 = 7 slash 7 slash braceleft seveneighths braceleft keycode 17 = 8 parenleft 8 parenleft bracketleft trademark bracketleft keycode 18 = 9 parenright 9 parenright bracketright plusminus bracketright keycode 19 = 0 equal 0 equal braceright degree braceright ... keycode 113 = ISO_Level3_Shift NoSymbol ISO_Level3_Shift ...

x2go - Problems (flicker) with fullscreen on Windows 10 after x2go server update
by Johannes Kind 26 Mar '18

26 Mar '18

Hi, I'm running x2goserver on Xubuntu 14.04. After updating x2go server via "apt-get --dist-upgrade" we have problems using x2go-client on MS Windows. We usually start the session in window-mode and by double-click on the head bar the window goes to fullscreen. After last upgrade fullscreen does not work anymore, the window flickers and is not really usable. Could anyone help? Which additional information do you need? I wanted to revert installation, but in cache there is just the current version: (f8-automation) johannesk@mgn-wx-rd-sit:~/dev/f8-automation$ apt-cache showpkg x2goserver Package: x2goserver Versions: 4.1.0.0-0~1517~ubuntu14.04.1 (/var/lib/apt/lists/ppa.launchpad.net_x2go_stable_ubuntu_dists_trusty_main_binary-amd64_Packages) (/var/lib/dpkg/status) Description Language: File: /var/lib/apt/lists/ppa.launchpad.net_x2go_stable_ubuntu_dists_trusty_main_binary-amd64_Packages MD5: e785564ddcdc9f9013b7175366b891a0 Description Language: en File: /var/lib/apt/lists/ppa.launchpad.net_x2go_stable_ubuntu_dists_trusty_main_i18n_Translation-en MD5: e785564ddcdc9f9013b7175366b891a0 Reverse Depends: x2goserver-common:i386,x2goserver 4.1.0.0-0~ x2goserver-common:i386,x2goserver 4.1.0.0-0~ libx2go-server-db-perl:i386,x2goserver 4.1.0.0-0~ libx2go-server-db-perl:i386,x2goserver 4.1.0.0-0~ x2goserver:i386,x2goserver x2goserver-x2goagent,x2goserver 4.0.1.20~ x2goserver-x2goagent,x2goserver 4.0.1.20~ x2goserver-x2goagent,x2goserver x2gomatebindings,x2goserver 4.0.1.4-0~ x2gobroker-agent,x2goserver 4.0.1.16-0~ x2goserver-common,x2goserver 4.1.0.0-0~ x2goserver-common,x2goserver 4.1.0.0-0~ libx2go-server-db-perl,x2goserver 4.1.0.0-0~ libx2go-server-db-perl,x2goserver 4.1.0.0-0~ x2goserver-fmbindings,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1.1~ x2goserver-fmbindings,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1 x2goserver-pyhoca,x2goserver 4.0.1.22-0~1197~ubuntu14.04.1.1~ x2goserver-pyhoca,x2goserver 4.0.1.22-0~1197~ubuntu14.04.1 x2goserver-xsession,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1.1~ x2goserver-xsession,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1 x2goserver-printing,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1.1~ x2goserver-printing,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1 x2golxdebindings,x2goserver 3.0.99.6-0~ x2goserver-compat,x2goserver 4.0.1.22-0~1197~ubuntu14.04.1.1~ x2goserver-compat,x2goserver 4.0.1.22-0~1197~ubuntu14.04.1 plasma-widget-x2go,x2goserver 3.1.1.2-0~ x2goserver-extensions,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1.1~ x2goserver-extensions,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1 x2godesktopsharing,x2goserver 4.0.0.0-0~ x2goagent,x2goserver x2goagent,x2goserver 4.0.1.21-0~ x2goagent,x2goserver 4.0.1.21-0~ x2goagent,x2goserver Dependencies: 4.1.0.0-0~1517~ubuntu14.04.1 - x2goserver-common (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-common (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) debconf (18 0.5) debconf-2.0 (0 (null)) init-system-helpers (2 1.13~) libfile-basedir-perl (0 (null)) libfile-which-perl (0 (null)) libtry-tiny-perl (0 (null)) libswitch-perl (0 (null)) libx2go-server-perl (2 4.1.0.0-0~1517~ubuntu14.04.1) libx2go-server-perl (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2goserver-x2goagent (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-x2goagent (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) bash (0 (null)) lsof (0 (null)) bc (0 (null)) openssh-client (0 (null)) openssh-server (0 (null)) pwgen (0 (null)) xauth (0 (null)) psmisc (0 (null)) net-tools (0 (null)) xfonts-base (0 (null)) xkb-data (0 (null)) rdesktop (0 (null)) pulseaudio-utils (0 (null)) sshfs (0 (null)) x11-apps (0 (null)) x11-session-utils (0 (null)) x11-utils (0 (null)) x11-xfs-utils (0 (null)) x11-xkb-utils (0 (null)) x11-xserver-utils (0 (null)) fontconfig (0 (null)) xinit (0 (null)) x2goserver-extensions (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-extensions (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2goserver-xsession (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-xsession (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2goserver-fmbindings (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-fmbindings (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2goserver-printing (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-printing (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2godesktopsharing (3 3.1.1.2-0~) x2godesktopsharing:i386 (3 3.1.1.2-0~) x2goserver-compat (0 (null)) x2goserver-compat:i386 (0 (null)) x2goserver-home (0 (null)) x2goserver-home:i386 (0 (null)) x2goserver-one (0 (null)) x2goserver-one:i386 (0 (null)) x2goserver-pyhoca (0 (null)) x2goserver-pyhoca:i386 (0 (null)) x2goserver-compat (0 (null)) x2goserver-compat:i386 (0 (null)) x2goserver-home (0 (null)) x2goserver-home:i386 (0 (null)) x2goserver-one (0 (null)) x2goserver-one:i386 (0 (null)) x2goserver-pyhoca (0 (null)) x2goserver-pyhoca:i386 (0 (null)) x2goserver:i386 (0 (null)) Provides: 4.1.0.0-0~1517~ubuntu14.04.1 - Reverse Provides: Thanks in advance and best regards, Johannes Kind ADVA SE Märzenquelle 1-3 98617 Meiningen Germany +49 3693 450 325

Found the issue with MxLinux, had monkeysphere installed, it causes perl to be called with the -T flag, and this made having insecure directories such as /etc or '.' in your $PATH problematic. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.
