Thanks! The client OS is in fact Windows, and I think they only have single user (like home edition or whats it called). We have tried connecting via putty and straight SSH works. We have tried giving x2go client a standalone VcxSrv but didn¹nt help. Is there a , I guess, well defined setting (local port(s) for X11?) to specifically check Antivirus for? -- Grigory Shamov WestGrid Site Lead / HPC Specialist University of Manitoba E2-588 EITC Building, (204) 474-9625 On 2019-02-19, 4:12 AM, "x2go-user on behalf of Stefan Baur" <x2go-user-bounces(a)lists.x2go.org on behalf of X2Go-ML-1(a)baur-itcs.de> wrote: >Am 15.02.19 um 17:00 schrieb Grigory Shamov: >> We are running X2go servers on CentOS 6 Linux; other clients (MacOS, >>other >> users with Windows 7 and 10) seem to connect fine.

Low speed of x2go server

It works quickly! >Is the entire desktop running slow, or only particular applications >(Firefox, for example)? Slowly works when I give a desktop. As I wrote before the application (firefox, openoffice) work quickly everywhere. LinuxLite 3.8/LinuxLite 4.2/Ubuntu 18.04 When I understood it I decided to change default style (Adapta) and icon theme (Papirus-Adapta) in LinLite 4.2 for others (did on the server not through x2go). After having connected by this user through x2go I found out that everything works quickly. I decided to double-check it. And again changed style and icons for default (Adapta) I very much was surprised, but everything continued to work quickly and well. I several times perezagrugit the x2go server every time being connected to it by the same user again and everything works quickly with windows and linux of clients. After I was connected from the thin client of TCE by the same user and all very slowly. Now I have such stable results with the user of "test" (Settings of clients identical): Windows client = quickly Linux client = quickly Thin client of TCE = very slowly Connection by any users not of "test" (Tried to change styles and icons): Windows client = very slowly Linux client = very slowly Thin client of TCE = very slowly I could not repeat magic which turned out with the user of "test" with other users. I cannot understand dependence in what prevents the x2go server to work quickly. But I was convinced that x2go the server can quickly work with linux Lite 4.2 Maybe somebody will prompt what in my case prevents x2go to work quickly? Or there can be I am mistaken what the style of a design and style of icons is guilty? There are ideas? -- С Уважением Строганов Роман

local X server fails to accept the connection?
by Grigory Shamov 20 Feb '19

20 Feb '19

HI All, A user of our system recently come with the following errors while trying to use X2go client on Windows 10. === Info: Forwarding X11 connections to display 'localhost:0'. Session: Session started at 'Thu Feb 14 12:51:37 2019'. Warning: Protocol mismatch or no X authentication data. Session: Terminating session at 'Thu Feb 14 12:51:41 2019'. Info: Your session was closed before reaching a usable state. Info: This can be due to the local X server refusing access to the client. Info: Please check authorization provided by the remote X application. Session: Session terminated at 'Thu Feb 14 12:51:41 2019'. === We are running X2go servers on CentOS 6 Linux; other clients (MacOS, other users with Windows 7 and 10) seem to connect fine. So the problem likely is with the client. I believe the Windows x2go client comes with an X11 server bundled with it and configured. Could anyone suggest what could be the reason for such errors, have anyone encountered them before? Any advice much appreciated! Thanks! -- Grigory Shamov WestGrid Site Lead / HPC Specialist University of Manitoba E2-588 EITC Building, (204) 474-9625

Hello! I configured x2go server on linux lite 3.8 (package base ubuntu 16.04 x64 xfce) clients on windiws, linux and the thin clients loaded with tce. Work speed very good. But I need to pass to linux lite 4 (package base ubuntu 18.04 x64 xfce) When I set Linux lite 4 and x2go server at connection to it from any client work speed very much and very low. It is impossible to work normally!: ( I use identical methods of a compression both in new and in the old version of the server. The server was installed according to the instruction on the website x2go from ppa: x2go/stable The list of the packets set at me: ii libx2go-log-perl 4.1.0.3-0~1708~ubuntu18.04.1 all Perl X2Go::Log package ii libx2go-server-db-perl 4.1.0.3-0~1708~ubuntu18.04.1 amd64 Perl X2Go::Server:DB package ii libx2go-server-perl 4.1.0.3-0~1708~ubuntu18.04.1 all Perl X2Go::Server package ii x2goserver 4.1.0.3-0~1708~ubuntu18.04.1 amd64 X2Go server ii x2goserver-common 4.1.0.3-0~1708~ubuntu18.04.1 amd64 X2Go Server (common files) ii x2goserver-extensions 4.1.0.3-0~1708~ubuntu18.04.1 all X2Go Server (extension support) ii x2goserver-fmbindings 4.1.0.3-0~1708~ubuntu18.04.1 all X2Go Server (file manager bindings) ii x2goserver-printing 4.1.0.3-0~1708~ubuntu18.04.1 all X2Go server (printing support) ii x2goserver-x2goagent 4.1.0.3-0~1708~ubuntu18.04.1 amd64 X2Go Server's X2Go Agent ii x2goserver-xsession 4.1.0.3-0~1708~ubuntu18.04.1 all X2Go Server (Xsession runner) Who faced x2go the ubuntu server 18.04?

Help need with Linux-Linux Kerberos Authentication
by rubens.zanatta＠grad.ufsc.br 25 Jan '19

25 Jan '19

Hello there. We're trying to use X2Go in our campus as a user friendly Linux-Linux remote desktop solution. We would also like a SingleSingOn approach, so we chose to use kerberos authentication between the Linux clients and the X2Go server. We already have a working KDC that authenticates a SSH server, as a test. On the client I have the Kerberos 5 Auth. option checked, but when I attempt the connection, the screen remains blank and never connects. The log shows this socket error but the authentication seems to be working. > x2go-INFO-8> "Starting connection to server: newhost.com:22" > x2go-DEBUG-../src/onmainwindow.cpp:3007> Starting new ssh connection to server:"newhost.com":"22" krbLogin: true > x2go-DEBUG-../src/sshmasterconnection.cpp:175> SshMasterConnection, host "newhost.com"; port 22; user "remoto"; useproxy false; proxyserver ""; proxyport 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:244> Starting SSH connection with Kerberos authentication. > x2go-DEBUG-../src/sshmasterconnection.cpp:252> SshMasterConnection, instance SshMasterConnection(0x55e041b1c730) created. > x2go-DEBUG-../src/sshmasterconnection.cpp:520> SshMasterConnection, instance SshMasterConnection(0x55e041b1c730) entering thread. > x2go-DEBUG-../src/sshmasterconnection.cpp:834> Session port before config file parse: 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:844> Session port after config file parse: 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:909> Session port before config file parse (part 2): 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:919> Session port after config file parse (part 2): 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:944> cserverAuth > x2go-DEBUG-../src/sshmasterconnection.cpp:985> state: 1 > > x2go-DEBUG-../src/sshmasterconnection.cpp:1633> Starting ssh:"ssh" "-o GSSApiAuthentication=yes -o PasswordAuthentication=no -o PubkeyAuthentication=no -p 22 -l remoto newhost.com bash -l -c 'echo \"X2GODATABEGIN:eb840c04-8bb1-44b2-b29f-e29332c0354e\"; export TERM=\"dumb\"; whoami; echo \"X2GODATAEND:eb840c04-8bb1-44b2-b29f-e29332c0354e\";'" > > x2go-DEBUG-../src/sshmasterconnection.cpp:1661> SSH exited. > x2go-DEBUG-../src/sshmasterconnection.cpp:1662> stdout: "X2GODATABEGIN:eb840c04-8bb1-44b2-b29f-e29332c0354e\nremoto\nX2GODATAEND:eb840c04-8bb1-44b2-b29f-e29332c0354e\n" > > x2go-DEBUG-../src/sshmasterconnection.cpp:1663> stderr: "" > > x2go-DEBUG-../src/sshmasterconnection.cpp:1664> Exit code: 0; status: QProcess::ExitStatus(NormalExit) > > X2GO-DEBUG-../SRC/SSHMASTERCONNECTION.CPP:726> USER AUTHENTICATION OK. > X2GO-DEBUG-../SRC/SSHMASTERCONNECTION.CPP:1727> "SSH_CHANNEL_OPEN_SESSION FAILED": "SOCKET ERROR: DISCONNECTED" > > x2go-DEBUG-../src/sshmasterconnection.cpp:735> Login Check - Failed > x2go-DEBUG-../src/onmainwindow.cpp:3167> Closed SSH Session interaction The documentation on the wiki is blank when it comes to the advanced section and kerberos authentication methods, and I could not find past use cases regarding this approach on the mailing lists (I could've missed it though).

We go on the server. We see the link "Data_Treveler" on a desktop and in / home/user/media/rm/Data_Treveler We return to the console of the thin client rm -rf /media/Data_Treveler Now on the thin client there is no Data_Treveler directory On the server in / home/user/media/rm/is empty as well as should be. But the link "Data_Treveler" on a desktop remained. Why I show consideration for it? If during one session the user used many different usb disks, then it will have many not working links on a desktop (garbage) and in / home/media/.

You are right. I use the translator. The description of a problem in my native language is lower При подключении usb диска к тонкому клиенту на нем создается каталог для ее монтирования (например /media/Kingston) Эта же директория пробрасывается на сервер x2go и там доступна. При отключении usb диска каталог монтирования /media/Kingston не удаляется автоматически на тонком клиенте и соответственно он виден на сервере, но пустой. Это вводит в заблуждение пользователей. Я думаю что при отключении usb диска на тонком клиенте должен удаляться каталог монтирования (в нашем случае /media/Kingston), а на сервере удаляться ссылки на флешку с рабочего стола и каталога пользователя -- С Уважением Строганов Роман

I will share the observations: I have 2 identical usb drive. One ntfs, other fat32. On both I create a directory "Новая папка" (new folder) and "новый файл.txt" (new file.txt) We connect both and we watch contents after mount in the console of the thin client: ls /media/ntfs_drive/ Новая Папка новый файл.txt System Volume Information ls /media/fat32_drive/ :041d:043e:0432:0430:044f :043f:0430:043f:043a:0430 :043d:043e:0432:044b:0439 :0444:0430:0439:043b.txt System Volume Information Later we go on the server. We open on the ntfs_drive server and we see normal Russian names of the file and a directory. It is possible to create new objects with the Russian names without problems. Checked even the Ukrainian alphabet. Everything is OK! We open on the fat32_drive server. There is a directory": 041d: 043e: 0432:0430:044f: 043f: 0430:043f: 043a: 0430" and file": 043d: 043e: 0432:044b: 0439: 0444:0430:0439:043b.txt".

I apologize. The problem was with my server. With forwarding usb drive I understood. When I used ltsp I tried to accelerate ssh. On the ssh_config server there was a record ciphers arcfour. Therefore could not set connection with the client on sshfs Now directories and usb drive are visible on the server, but with the Russian names of directories or files a problem is created. usb flash forwarded on the server from the thin client: directories and files with the Russian names are displayed approximately so": 041d: lfjh:..... tt". New directories / files with the Russian names are not created. Forwarding directory /home/user/Документы from simple linux (not the thin client) forwards empty directories. If I forward a directory in Latin, it forwards it, but everything is farther as with the thin client. Names are displayed not correctly, and nothing with the Russian names can be created...: ( -- С Уважением Строганов Роман

You are right! On the x2go server there are no forwarded disks/directories from clients. The thin client tried from clients of Linux, win. In a directory of the user there is a link to directory/media, in 3 subdirectories of CD, disk, rm. All of them are empty. Earlier everything worked on this server as 100% I shared disks from Linux/win of clients with x2go the server. I decided to check is on the x2goserver-fmbindings server The packet of x2goserver-fmbindings of the newest version is already set (4.1.0.3-0 ~ 1708 ~ ubuntu16.04.1). The following packets were established automatically and any more are not required: linux-headers-4.4.0-112 linux-headers-4.4.0-112-generic linux-image-4.4.0-112-generic linux-image-extra-4.4.0-112-generic For their removal use "sudo apt autoremove". It what depends on the version of a kernel? At me now 4.4.0.142. Maybe updating what that broke? I have a backup copy. I can try to recover it (I do not know what a kernel there) If earns - any more never to update a kernel? -- С Уважением Строганов Роман

Unfortunately at me not to receive the thin client to the x2go server... On the thin client I see the console localhost login text: Sometimes it is very quickly visible some blue screen and again the console. I have a computer about Linux and x2go the client. From it I am well connected to the server. I took from it the work file sessions and copied it as x2go-tce-sessions on http the server. The file from the server is downloaded normally. At line with APPEND in the end added fetch= http://10.3.1.117/x2go-tce/x2go-tce-filesystem.squashfs sessionsurl= http://10.3.1.117/x2go-tce/x2go-tce-sessions session=tsu to the file of a configuration In the sessions name=tsu file (I tried to write session=0123456 as at the beginning of the session [0123456] file) Nothing is impossible. On the thin client I see the console localhost login text: Sometimes it is very quickly visible some blue screen and again the console. What can be made? Can as that it is possible to look at log on the thin client? added debug to APPEND. But how to look at it I do not know. I seem to me close to the purpose -- С Уважением Строганов Роман

x2go on Windows 10 - crashes on connect - problem libssh version

Hello, The following versions crash on connect from Windows 10 to a Fedora 28 server: x2goclient-4.1.0.0-2017.03.11-setup.exe x2goclient-4.1.1.1-2018.03.01-setup.exe x2goclient-4.1.2.0-2018.06.22-setup.exe x2goclient-4.1.2.2-2018.11.30-6596556-setup.exe The last good known version is: x2goclient-4.0.5.2-2016.09.20-setup.exe UAC is disabled on this computer When I copy libssh.dll from x2goclient-4.0.5.2-2016.09.20 to the newer version, everything works well. Solution and summary: x2goclient-4.1.2.2-2018.11.30-6596556-setup.exe with libssh.dll from x2goclient-4.0.5.2-2016.09.20-setup.exe is OK!!!!!!!! OK: libssh 0.7.0 NOK: libssh 0.7.4 Can you please update libssh to https://www.libssh.org/files/0.8/libssh-0.8.6.tar.xz (and include Pageant support, fixes also some security leaks) OpenSSL upgrade to 1.1.1a would also be fine (currently 1.0.2n is installed, one year old). If I should test something let me know. Thank you. Ciao, Gerhard

I have several thin clients who 512 MB have RAM. At the others 1 GB and more. If I correctly understood x2go tce-live it is loading of FAT clients? Their start pudt long? I plan about 15-20 clients only in local network. The network is very stable. Use of nfs is quite possible. I would like to try x2go tce-live but there are some difficulties. I am not a really experienced user of Linux. Therefore I need the detailed instruction. https://wiki.x2go.org/doku.php/doc:howto:tce it is badly clear to me that to do. The stage "Building your own X2Go-TCE Image" What there to do? It is a script? The instruction for the x2go tce-classic installation is more clear to me therefore began with installation of this version. Still I did not find as after installation to adjust tce-live... Maybe it will be difficult for me? I will be grateful for the help in control! -- С Уважением Строганов Роман

Tooltips, pull-down menus, and context menus too far away
by Tristan Miller 09 Jan '19

09 Jan '19

Dear all, I've recently started experiencing a problem when running single applications over X2Go. Quite often small windows such as tooltips, pull-down menus, and context menus get positioned far, far away from where they are supposed to be. For example, I'm currently writing this message in Claws Mail; when I activate the "Edit" pull-down menu, the menu doesn't appear under the menu bar but rather way over on my second screen. (I use a dual-monitor setup.) The problem happens with a lot of different applications, but not always consistently. For instance, sometimes I might hover my pointer over a widget that causes a tooltip to display halfway across the screen, and a minute or two later I'll do the same thing but this time the tooltip will display right over the widget like it's supposed to. Is this a bug in X2Go or in my window manager? I'm running the X2Go Server 4.1.0.4 on openSUSE Tumbleweed, and connecting from X2Go Client 4.1.1.1 on openSUSE Leap 15.0, using KDE Plasma 5.12.6. (I can't upgrade the connecting system at the moment because the x2goclient package seems to have disappeared from the repository at <http://packages.x2go.org/opensuse/15.0/main/x86_64/>.)

Unwanted session suspension on an unreliable network
by Peter Oliver 08 Jan '19

08 Jan '19

When using the Windows X2Go client on an unreliable network, I regularly receive the message “The connection with the remote server was shut down. Please check the state of your network connection”. I am forced to reconnect to my X2Go session, but a PuTTY connection to the same server typically continues to work without interruption once the network comes back a few moments later. I assume that X2Go is actively checking the state of the connection, in a similar way to OpenSSH’s ServerAliveCountMax/ServerAliveInterval configuration options. Is there any way to switch this functionality off in X2Go? -- Peter Oliver

X2Go client compatibility with Debian 9 Buster
by Colin E 26 Dec '18

26 Dec '18

X2Go Client: v4.0.3.0 Client OS: Windows 7 Pro 64bit I've been using X2Go to give me a windowed access method for my headless home server running Debian 8 Jessie for couple of years. Unfortunately that means my memory is a bit hazy on the X2Go setup details :-} The client PC and server are on the same local LAN with no intervening firewalls or other complexities. I'm using the XFCE desktop on the server. I upgraded the server OS to Debian 9 Sid a couple of days ago, and unfortunately that seems to have broken X2Go. The X2Go docs say "If SSH login works, X2Go will work, as well", but that's not what is happening here. I can SSH to the server perfectly ok from my PC (using PuTTY), but If I try to access the server using the existing X2Go sessions I have set up (one for a fullscreen client session, one for a windowed one) I get the following error: Access denied. Authentication that can continue: publickey, password These existing sessions use a stored id_dsa key file (that has not changed). If i try to set up a new session, using the same id_dsa key, I get the same error when I try to use it. This does look like an SSH error, but i'm not clear where I should be looking for the error. Any hints much appreciated.

Problem connecting from Mac to Linux
by Darby Vicker 25 Dec '18

25 Dec '18

Hello, I've used x2go on a very similar setup in the past but I'm running into a problem on a new installation. I've installed x2goserver on a CentOS 7.5 machine. I'm trying to connect from a Mac running 10.13. I can ssh password free between the machines with no issues. When I try to connect I get this in my client window: Error: Failed to resolve address of 'localhost'. Loop: PANIC! Unknown remote host 'localhost'. Error: Unknown remote host 'localhost'. Session: Session terminated at 'Tue Nov 27 08:06:01 2018'. On the server side, I see this in /var/og/messages: Nov 27 08:06:01 valkyrie /usr/bin/x2gostartagent: successfully started X2Go Agent session with ID dvicker-51-1543331158_stDMATE_dp32 We don't have the server machine in DNS yet so I'm using the IP address for now. I've made sure the IP address is in /etc/hosts of the server machine and matches the hostname. Any other ideas? Is there a way to disable the host lookup? Darby

x2godesktopsharing applet starts twice in KDE Plasma
by Víctor J. Sánchez 15 Dec '18

15 Dec '18

Hi all, I recently installed x2godesktopsharing via X2Go repositories for Debian. The installation asked me about activate the auto-start feature (I said yes) and enable shared desktop (I said no). When I reboot the machine in KDE Plasma desktop I see two x2godesktopsharing applets in system tray and the next error message is displayed (translated into english): /The application X2Go DesktopSharing is already active for this screen/ /if it doesn't run remove /tmp/x2godesktopsharing.lock_USER@:0 and start it up again/ I don't know about x2godesktopsharing is started because I can't find anything in the documentation about it. I only see the file /etc/xdg/autostart/x2godesktopsharing.desktop but I don't see any system service (systemctl) nor KDE Plasma desktop's startup service or script. How could I resolve this issue? Some data about my system: - Debian testing (amd64), kernel 4.18.0-3-amd64 - KDE Plasma 5.14.3 - x2godesktopsharing 3.2.0.0 Thanks in advance.

x2gocleansessions
by richard lucassen 04 Dec '18

04 Dec '18

Hello list, I reported this issue earlier in the year, the process "x2gocleansessions" is checking for sessions each 2 seconds. The 2 seconds is on line 166 in /usr/sbin/x2gocleansessions: while(sleep 2) I have no idea why this process is started that often, but IMHO it's making quite a lot of noise for a 2 seconds check. It writes tmp files to the tmp directory and removes them. When using an ssd this will update the stat of the /tmp/ directory each two seconds. Can anybody explain why this process is started so often? Or is it still in a sort of debug/test mode? In my case I'm a single user on a single system, I changed the line 166 to 3600, but wouldn't it be a better idea to put that time into /etc/x2go/x2goserver.conf?

Upcoming Deprecation of EOL Distributions
by Mihai Moldovan 22 Nov '18

22 Nov '18

Hi In order to lower resource stress when building packages, I plan to deprecate support for distributions that have reached End Of Life on December 31th 2018. This includes the following distro versions: - Fedora o 26 o 27 - OpenSuSE o 42.1 o 42.2 - SLES o 12.0 Ubuntu builds are ceased automatically after upstream deprecation (minus special exceptions). SLES 12.0 builds will be replaced by SLES 12.3 (12 SP3) builds, since SLE 12.0 has long been deprecated and newer versions include proper Qt5 support, which the initial version lacked. After deprecation, no new builds will be published and existing builds will be moved to the archive repositories to discourage users from installing unmaintained software. Mihai

suspended sessions are not restoring
by David Barron 12 Nov '18

12 Nov '18

My problems with suspended sessions are continuing, so I am forced to continue requesting help. Of course, I'm using -broker-url with the client, but if I do not and I create my sessions, they suspend perfectly. So whatever the issue is, it appears to be related to broker. Any help would be appreciated.
