Bug#1356: Unable to find the sftp-server binary
by Mihai Moldovan 18 Jun '19

18 Jun '19

Something's very odd here. /usr/lib/openssh is Debian's and Ubuntu's default directory for sftp-server and already included in our client code. Are you really positive, that the binary is *there*? If yes, what does ls -ldh /usr/lib/openssh/sftp-server say? Mihai

X2Go: The Gathering 2019 (2019-09-27 to 2019-09-29) will take place at Linuxhotel, Essen, Germany
by Stefan Baur 18 Jun '19

18 Jun '19

Dear $ALL, As stated in the subject line, X2Go: The Gathering 2019 will take place at Linuxhotel, Essen, Germany, from Friday afternoon, 2019-09-27, to Sunday afternoon/evening, 2019-09-29m and will, again, be a three-day "work and play" (coding, chatting, sightseeing, socializing). X2Go: The Gathering is the annual event where users, admins, and developers (including the i18n volunteers) of X2Go meet face to face, to discuss current X2Go-related issues, fix open bugs, and have a good time getting to know each other. As there is some overlap between X2Go, Arctica, and orca e.V., you can expect to see members of those groups as well. *ATTENTION!* If you want to join us *and* want to sleep in one of the hotel rooms at the Linuxhotel, we need the number of beds and nights you want to reserve, as well as *your full name* (as printed on your passport) and *your nationality* by *2019-08-19* *23:59:59* *CEST* (yes, that's 2019-08-19, *not* 2019-09-19)!!! Very important!!! After that date, we will be unable to reserve a room for you! First come, first serve! As single rooms are in short supply, please book your bed in a 2- or 3-bed room, unless you absolutely have to use a single room. Please send your reservation request to X2Go-ML-1(a)baur-itcs.de with the text "The Gathering" somewhere in the subject and bug me publicly on the X2Go-Project list if you don't receive a confirmation by e-mail after a day or two. Currently, the following core team members already have valid registrations and thus do not need to re-register: - Baur, Stefan 'Stefan#1' (BAUR-ITCS) - DePaulo, Michael Swinick 'Mike#2' - Mike 'Mike#1' Gabriel (DAS-NETZWERKTEAM) - Grabowski, Juri (LiHAS) - Moldovan, Mihai 'ionic' (BAUR-ITCS) - Sibiller, Ulrich - Graesing, Heinz-M. 'h1.org' - Shneyder, Oleksandr 'Alex' (phoca) If for some reason or other you do *not* need a place to sleep at Linuxhotel, but *do* want to join us, please *still* let us know in advance that you're planning to visit. There's no such hard deadline as for the room reservations, but you will need to "check in" (and there will be an "Admission fee") for our gathering with the Linuxhotel staff, so please *do* let us know in advance. We will be updating the Wiki page <http://wiki.x2go.org/doku.php/events:x2go-gathering-2019> as more information becomes available. Certain things, like our breakfast options, or having lunch/dinner served by Linuxhotel instead of having to order from a delivery service, can only be planned once we know the exact number of participants. Since we're still in the early planning phase, we do not yet have any sponsors for the event (though we plan to approach the "usual suspects" from previous years), so if you know someone willing and able to co-sponsor the event, please let me know at <X2Go-ML-1(a)baur-itcs.de>. Whether they wish to send us some "swag" with their company branding, or pledge money that we can use to lower dining and lodging costs for our participants, their sponsorship is greatly appreciated. Sincerely, Stefan Baur, "X2Go: The Gathering" event organizer -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243

Bug#1391: X2Go Flickering on KDE remote desktop with compositor enabled
by Tom Butler 17 Jun '19

17 Jun '19

Package: x2goserver Version: 4.1.0.3 I am using X2Go to connect to a running KDE desktop over a gigabit LAN connection. Both the client machine (running x2goclient) and the server are running KDE Plasma 5.15. When the compositor is enabled, it causes flickering. It's most visible on windows with transparency effects like the taskbar and menu, however the window decorations of any window also flickers. I have uploaded a video of the problem here: https://www.youtube.com/watch?v=Hg8g1TXLndo a rather unpleasant experience. The server uses Intel graphics with an i7 8650u if it's a GPU/driver issue. The flickering does not happen on the server's display, only when viewed using x2go. The same thing happens in VNC, though it is significantly less frequent/annoying. Ideally, x2go would support the compositor. Is it possible to just do full-screen polling? I can stream an x264 or vp9 video of the screen from the host and view the desktop that way but obviously that lacks input, although inefficient, it would solve any display issues if x2go could just stream a complete video from ffmpeg and then handle the input. However, a workaround would be disabling the compositor on a connection. Is there currently any method that I can run a script on connect/disconnect or even just ask x2goserver how many clients are connected so I can stop the compositor when an x2go client connects and then re-enable it when there are no clients?

Bug in sshproxy handling
by Ulrich Sibiller 16 Jun '19

16 Jun '19

Hi, some time ago I have successfully set up the x2goclient 4.1.0.0 for Windows to access some Linux machines via an ssh security gateway. It worked fine. Yesterday I wanted to use that connection with x2gclient 4.1.2.0 and it failed. Today I have tracked this down a bit more and can report this information: - it works with 4.1.0.0 - it stops working with 4.1.1.1 or newer - the session configuration looks like this: - Server: - Host: destination host behind the gateway - Use proxy server for ssh connection - Proxy: - Proxy type: ssh - Proxy host: gateway - Proxy port: 22 - use same user as for x2go server - The connection interactively asks for the password of the gateway and fails directly after entering it. The gateway is setup like this: 1. ssh <user>@gateway 2. run one of two valid commands. Any other command will immediately abort the connection to the gateway. The main allowed command is ssh to a number of defined hosts. The other command is irrelevant here. Here's some log: (invalid command) ------------------------------------ $ ssh user@gateway Password: [entering my secure password from password generator] Last login: Thu May 16 15:30:02 2019 from [CENSORED] Enter command: echo test Connection to gateway closed. ------------------------------------ Here's some log: (valid command) ------------------------------------ $ ssh user@gateway Password: [entering my secure password from password generator] Last login: Thu May 16 16:08:59 2019 from [CENSORED] Enter command: ssh desthost key_from_blob: remaining bytes in key blob 36 ssh-keysign not enabled in /usr/pkg/etc/ssh/ssh_config ssh_keysign: no reply key_sign failed Last login: Tue Apr 30 16:37:30 2019 from CENSORED [Prompt on desthost] $ ------------------------------------ Working debug log (4.1.0.0): ----------------------------------------------------------- x2go-DEBUG-../src/onmainwindow.cpp:2860> Starting new ssh connection to server:"desthost":"22" krbLogin: false x2go-DEBUG-../src/sshmasterconnection.cpp:175> SshMasterConnection, host "desthost"port 22user "username"useproxy trueproxyserver "gateway"proxyport 22 x2go-DEBUG-../src/sshmasterconnection.cpp:212> Starting SSH connection without Kerberos authentication. x2go-DEBUG-../src/sshmasterconnection.cpp:216> SshMasterConnection, instance SshMasterConnection(0x318fb40) created. x2go-DEBUG-../src/sshmasterconnection.cpp:452> SshMasterConnection, instance SshMasterConnection(0x318fb40) entering thread. x2go-DEBUG-../src/sshmasterconnection.cpp:456> proxyserver: "gateway"proxyport: 22proxylogin: "username" x2go-DEBUG-../src/sshmasterconnection.cpp:175> SshMasterConnection, host "gateway"port 22user "username"useproxy falseproxyserver ""proxyport 0 x2go-DEBUG-../src/sshmasterconnection.cpp:212> Starting SSH connection without Kerberos authentication. x2go-DEBUG-../src/sshmasterconnection.cpp:216> SshMasterConnection, instance SshMasterConnection(0x318fbf8) created. x2go-DEBUG-../src/sshmasterconnection.cpp:452> SshMasterConnection, instance SshMasterConnection(0x318fbf8) entering thread. x2go-DEBUG-../src/sshmasterconnection.cpp:488> libssh not initialized yet.

I think that login check is issuing a command on the proxy to check if the proxy is working ("echo LOGIN OK"). And due to the nature of our gateway (see above) this fails, because it is an invalid command. Unfortunately I don't really see if this assumption is correct because I have no access to the gateway logs and the x2goclient logs do not contain any information _why_ the login check failed. I have tried getting some gateway logs but I have not yet gotten anything. Is there anything I can do to bypass that login check? Uli
