Bug#58: x2goplugin: after session startup whole local desktop unusable
by Mike Gabriel 26 Mar '19

26 Mar '19

Package: x2goplugin Severity: grave Version: 3.99.3.0 Hi Alex, more tests with x2goplugin + x2goplugin-provider as release with x2goclient src:package 3.99.3.0. Try this: o install x2goplugin-provider and x2goserver locally on the same machine o visit http://localhost/x2goplugin.html o launch the pre-configured session o ... till here, everything works fine now... On my machine: after the session has come up (actually already while it is comming up) my whole desktop shell (awesome) refuse to accept almost any import from keyboard or mouse. I can neither click any of the x2goplugin controls nor can I click around in the started up X2Go session. The X2Go session is embedded in the x2goplugin frame, just in case this information is relevant.

You can use xprop -root to check if you are running inside an nxagent: e.g.: $ xprop -root NX_AGENT_VERSION NX_AGENT_VERSION(STRING) = "3.5.99.19"

Hi, some time passed, but finally I found the time to do a testrun on a dedicated setup based on upstream arctica libraries my colleague compiled to deb packages and installed on a VM. The currently tested version is a bit outdated from branch 3.6.x: ---- snip ---- nx-libs$ git log -1 commit 9acd13e50c3bde9105f6143922028f0de0d4ae50 Author: Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Date: Mon Dec 19 15:03:09 2016 +0100 release 3.5.99.3 nx-libs$ git remote -v origin git://github.com/ArcticaProject/nx-libs.git (fetch) origin git://github.com/ArcticaProject/nx-libs.git (push) ---- snip ---- The behavior is the same as before, the session dies at some time during some interaction with the tools window. I tried 64k-png and 15m-jpeg-9 modes with the same outcome, see attached logs for details.

by Ulrich Sibiller 18 Mar '19

You mean NX, I guess, not X2 (there's no such protocol). However: I am using NX over two chained WANs without such problems. For some time I even used it for working on machines on the other side of the Atlantic ocean - and it worked flawlessly. @Yan: you could try setting the connection type to ADSL or even ISDN and retry.

Bug#1377: Upgrade to Windows 10 version 1809 break X2Go, can't read user name with space

Package: <X2GoClient-4.1.2.0-2018.06.22-setup.exe> Version: <4.1.2.0> X-Debbugs-CC: barry.pangrle(a)esperantotech.com 1-After updating from Window 10 Ver 1803 to 1809; x2go doesn't work any more. 2- It fails with the following messages: Loop: PANIC! Can't open options file '/cygdrive/C/Users/Barry'. Error is 2 'No such file or directory'. Error: Can't open options file '/cygdrive/C/Users/Barry'. Error is 2 'No such file or directory'. Loop: PANIC! Can't open options file '/cygdrive/C/Users/Barry'. Error is 2 'No such file or directory'. Error: Can't open options file '/cygdrive/C/Users/Barry'.

Error: Can't open options file '/cygdrive/C/Users/Barry'. Error is 2 'No such file or directory'. Connection timeout, aborting Looking at the "options" files now generated under Ver 1809, they look like: nx/nx,root=/cygdrive/C/Users/Barry Pangrle/.x2go,connect=localhost,cookie=064e8b5bdd350e061f76b243b8d5b5e5,port=35936,errors=/cygdrive/C/Users/Barry Pangrle/.x2go/S-bpangrle-51-1546910140_stDMATE_dp32/sessions:51 An "options" file generated under Ver 1803 looks like: nx/nx,root=/cygdrive/C/Users/BARRYP~1/X2GO~1,connect=localhost,cookie=e8a3a18f683a68163533a911fad81985,port=45490,errors=/cygdrive/C/Users/BARRYP~1/X2GO~1/S-bpangrle-51-1545005939_stDMATE_dp32/sessions:51 It looks like the old version used to use "BARRYP~1" in the path instead of "Barry Pangrle" and based on the error messages, it seems to not be able to trace through the " " in the path name. 3. Expect to read folder with space and replace with ~ instead of space. 4. X2go can't read space, can't replace with ~ and failed. Also, please list the following info: The client machine's OS (e.g., “Windows 10 pro version 1809”) The client machine's version of X2GoClient: 4.1.2.0 The server's OS: CentOS 7, worked with Windows 10 version 1803

Bug#1373: kex error : no match for method mac algo
by Danie de Jager 18 Feb '19

Package: client The client does not support chacha20 as I get this error when I try to connect to the X2Go server. I did harden my SSH configuration as guided by Mozzila https://infosec.mozilla.org/guidelines/openssh When I use defaults it works fine. It seems that the library used by X2Go is missing some newer methods.

Linux Mint 19.1 x2goserver connection problems
by Montjoy, Robert (montjoy) 15 Feb '19

15 Feb '19

HI.. We are running x2go on the linux mint with mate. All latest patches installed. Until recently we have not had any problems with x2go. Maybe it is a recent patch (maybe one of the ssh patches) or something. Anyway, right not when a user tries to connect to the server it works about 1 in 5 or 10 times. The logs usually have something about "xauth" failing on the failed attempts. I have included a client side log at the bottom of this Email. I will dig up the server side log if you need it. Once we get a connection it seems fine with the exception that Mate shows everything in the dock twice (including the menu). I do not remember it doing that before. XFCE is also failing as well. Note: We have tried the Windows client on Windows 7 and Windows 10 as well as the client on Linux mint. They all seem to have the same problem. If any of you have any hints on what direction to pursue I would appreciate it. I am sending the users with this problem back to VNC which is not a very good solution. I really do not want to do that.
