The future of x2gokdrive
by Oleksandr Shneyder 07 May '20

07 May '20

Hello guys, this is for those of you how is wondering in which direction development of x2gokdrive is going. As you may know, I mostly working now on the development of x2go kdrive, which will be used parallel to NX. The client part of x2go kdrive is quite simple and not depends on Xorg, which makes possible to create the clients for mobile and web platforms. I made some proof of concept and quickly developed a simple HTML5 client which is connecting to x2gokdrive over websockets. I used websockify to connect ws to tcp socket. The client has limited support for mouse and keyboard events, no support for cursors, but it's enough to create the image how it'll work. I attached the screenshot of plasma5 session running in browser tab with libreoffice and youtube video running in browser. regards, Alex -- ----------------------------------------------------------- Oleksandr Shneyder | Email: o.shneyder(a)phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Schleiermacherstr. 2 | Fax. : 0911 - 14870374 9 D-90491 Nürnberg | Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Resizing bug
by Kees Bakker 07 May '20

07 May '20

Hi, The client shows a weird resizing bug. I want to know what I can do to analyse this further and report it as a bug. I've mentioned this already earlier on the [X2Go-User] mailing list [1]. I'm surprised that I'm the only one seeing this, because I see it on all the environments that I work on. That is, on all PCs where I am logged in with the standard Ubuntu desktop. My client is Ubuntu (with Ubuntu desktop) and the server side is Ubuntu with a Mate (or Openbox or XFCE) session. Also worthwhile to mention that I don't have my x2go client full screen. When I move(!) the X2GO window, it resizes(!). And when I keep the mouse clicked on the top bar for the move, (and even if I don't move anymore) it keeps resizing until it reaches the maximum height of my local monitor. BTW. That maximum monitor height is not(!) the maximum height of my local window manager. The maximum height for the X2GO client window is the monitor height minus the height of the top bar. What I also noticed is that the height increments in steps of 37 pixels. I'm not sure, but I think the the height of the top bar in the Ubuntu desktop is 37. Here are the last few lines of the remote session.log. I start with a session of 800x600 Info: Screen [0] resized to geometry [799x600] fullscreen [0]. Info: Screen [0] resized to geometry [799x674] fullscreen [0]. Info: Screen [0] resized to geometry [798x674] fullscreen [0]. Info: Screen [0] resized to geometry [798x711] fullscreen [0].

Stefan: Well you are correct in that it doesn't seem to be needed. I disabled it as a start-up application and it makes no difference on my ability to log in to the remote machine. Thinking about it now, I'm not sure of it's intended use; if I'm logging into an unattended remote machine and starting a new session, then desktop sharing is not required. If I'm logging in to a remote machine to share a desktop with someone local to it at the other end, they can always start the desktop sharing service manually. Either way it's not an issue. Never the less, thank you for your informative responses. brian > Message: 3 > Date: Mon, 4 May 2020 19:17:15 +0200 > From: Stefan Baur <X2Go-ML-1(a)baur-itcs.de> > To: x2go-user(a)lists.x2go.org > Subject: Re: [X2Go-User] multiple instances of x2go server appearing > in tray > Message-ID: <78d6d9c8-83c6-adba-c4cf-45197237add2(a)baur-itcs.de> > Content-Type: text/plain; charset=utf-8 > > Am 04.05.20 um 19:03 schrieb b salzano: > > Stephan: Abject apologies - I misstated the issue.

Stephan: Abject apologies - I misstated the issue. The tray icon is indeed for x2go desktopsharing, and that is exactly the function that I need to use. So the question I meant to ask, then, is whether there is a config file somewhere that will prevent more than one instance of desktopsharing to run in a particular account. Xfce (what I normally use) doesn't provide any options to manage that aspect. Perhaps someone knows what config file to look at?

In fact, X2GoServer doesn't display any icons in your tray (X2GoClient does that on the client side, obviously).

If you do want to use it, you need to find out why the applet is being started multiple times. -Stefan -- 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

How to start a specific program from the client command line?
by Chris Green 03 May '20

03 May '20

I have been using x2go for a while now to run a couple of desktop programs on my laptop, I also use it to run the whole of the desktop's xfce session sometimes. It's excellent, thank you all. I currently have an icon in my panel which runs the following:- x2goclient --session=<session name> This brings up the x2go client GUI with the appropriate session loaded and asks for my password. Being a command line junkie I'd quite like to bypass the GUI if I can, so is there any way to get x2go[client] to ask for the password on the command line and go on to run the session? Alternatively can I get x2go to use ssh's ControlMaster setting as I nearly always have an ssh session running to my desktop so further ssh connections don't ask for my password again. -- Chris Green

multiple instances of x2go server appearing in tray
by brian 03 May '20

03 May '20

Hello x2go user list: New user. Hope I'm in the right place. If not, please direct me to that. Just discovered x2go a short while ago and am really enjoying it. Its a super piece of software. The only strange thing I'm encountering is that my tray will display up to 8 or 9 instances of x2goserver running at any one time. Only one will show OK (green check mark), the others will show with a red 'x' instead. The number of x-ed out server instances vary. Might be one. Might be 8. Entirely random. See attached photo. I can close each x-ed out entry indivdually and x2goserver still works just fine after that. In fact it shows no problems at all; works perfectly. I'm running on linux, Debian, Buster 10. A hardinfo report on the OS, kernel, and environment is also attached. Is there any config file I can go to to eliminate this one little quirk? Thanks for the help. brian

Question about the change in proxy/nx3.py
by Pavel 30 Apr '20

30 Apr '20

Hi, I am using my own small python application which is based on X2GoClient class from python-x2go. The application runs on windows, so it is necessary to start nxproxy.exe. The binary sits in C:\Users\user\win_apps\nxproxy\nxproxy.exe and in my app I set the environment variable NXPROXY_BINARY pointing to this path. This whole thing worked very well with python-x2go==0.5.0.6. Now I am on my way from Python2 to Python3, so I noticed, the newer version of python-x2go is also trying to be Python3 compatible. I made the necessary changes in my app and updated python-x2go to 0.6.1.3. But my application stopped to work. The reason was, nxproxy.exe didn't start. I tried to find out the problem and noticed there is an error log file in C:\users\user\.x2go\S-user-50-1588199962_stRxterm_dp32 containing: Loop: PANIC! Can't open options file '.\..\S-user-50-1588199962_stRxterm_dp32\options'. Error is 2 'No such file or directory'. Error: Can't open options file '.\..\S-user-50-1588199962_stRxterm_dp32\options'. Error is 2 'No such file or directory'. So I looked further and noticed this change in nx3.py between 0.6.0.2 and 0.6.1.0: - self.PROXY_OPTIONS= [ 'nx/nx', 'options=%s' % os.path.join("\\", "..", "S-%s" % self.session_info.name, 'options'), ] + self.PROXY_OPTIONS= [ 'nx/nx', 'options=%s' % os.path.join(".", "..", "S-%s" % self.session_info.name, 'options'), ] I reverted this change and my app worked correctly again. Now my question is: what is the motivation to change the path to options file and eventually, if the change is correct, what should I do in my app to be able to start nxproxy.exe again? The path to options file look as relative path, but to what? To nxproxy binary, or to nxproxy directory, or to session_id directory? The explanation would be very welcome. Thanks in advance. Pavel

X2Go, MFA and Duo?
by James M. Pulver 28 Apr '20

28 Apr '20

Has anyone ever used X2Go Client (windows, linux, mac) with some sort of MFA that works in SSH? Duo and PortalGuard both support SSH MFA with either a "line client" or easier IMHO an appended password. I was wondering if Duo with the appended code to the password field might work? Also, is there any plans to add a second password field to the clients al la Cisco AnyConnect etc? Thanks, -- James Pulver CLASSE Computer Group Cornell University

We have SmartCard support as well (quite obviously, as X2Go started out as a replacement for SunRay workstations), that's just handled differently.

Also, is there any plans to add a second password field to the clients al la Cisco AnyConnect etc? X2GoClient has out-of-the-box support for several 2FA solutions: <https://code.x2go.org/gitweb?p=x2goclient.git;a=blob;f=src/sshmasterconnect…> 53 "Verification code:", // GA (http://github.com/google/google-authenticator) 54 "One-time password (OATH) for", // OATH (http://www.nongnu.org/oath-toolkit/pam_oath.html) 55 "passcode:", // MOTP (http://motp.sourceforge.net) 56 "Enter PASSCODE:", // SecurID 57 "YubiKey for" // YubiKey (https://en.wikipedia.org/wiki/YubiKey) If Duo needs an appended code, it should work out of the box as well; if not, it will need to use either one of the prompts above to work out of the box, or one unique to Duo that we can add to a future client release. Frankly, I don't see a reason for the hype around Duo - what does it do that any of the established 2FA solutions can't do? When we looked at that after a customer had asked us about it, all it seemed to do was add a single point of failure, as it needed to "phone home" to a central Duo server (not under the customer's control) before being able to grant access. Block/sabotage that connection and you've essentially DoS'ed the system. Solutions based on Google Authenticator, or more generally, OATH, need no such external connection. I would assume the same goes for MOTP, YubiKey and SecureID. My personal favorite at the moment is Google Authenticator, which, despite what its name might suggest, does not "phone home" to Google. And you don't need to run the actual Google-Authenticator-App on your phone, either - any open source OTP app that supports TOTP OATH will do. Not sure what Cisco AnyConnect does or why we should add a second password field on the default login screen - that doesn't seem to make sense. All that would do is confuse users that don't use 2FA. And we don't know if a server uses 2FA or not until after we've provided a username and password to it, so there's no way of determining whether or not we should present a field for the 2FA code on the login screen. Hence, the popup for it. -Stefan -- 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 _______________________________________________ x2go-user mailing list x2go-user(a)lists.x2go.org https://lists.x2go.org/listinfo/x2go-user Dit bericht kan informatie bevatten die niet voor u is bestemd.

X2Go Windows Client 4.1.2.2 Crashes Upon Connect
by Josh G 09 Apr '20

09 Apr '20

I just installed the Windows client version 4.1.2.2. It crashes as soon as it tries to make the SSH connection. I tried debug and the debug window closes immediately as well. Is there a log somewhere? It was tried on two different machines that have different OSs and virus protection. 4.1.2.0 works fine. It doesn't crash when attempting to connect to a computer that isn't running SSH (just times out). It does crash when trying to connect to that same computer by tunneling through another machine that is running SSH. If I try to connect to a new machine, it crashes as soon as I accept the host key. If you put in a wrong password, it still crashes. Thus, there is never a completed SSH connection. Is there anything I can look at or do? I was hoping that 4.1.2.2 would fix some of the annoyances that prevents me from deploying X2Go to other users.Thanks,Josh

It worked really well with a Linux x2goclient (fedora 31, x86_64)using : - a connection to the server through an ssh proxy with password. - a connection using a session from a x2gobroker server with the same login/password/server. I tried the same tests with a Windows 10 pro x2goclient. The first test, a connection to the server through an ssh proxy works fine. But, when my x2goclient use the session from the x2gobroker (same x2goserver/use/password), the connection failed. My client write the following error: failed to resolve the hostname ... (x2gserver) In fact, the x2goclient seems to try a direct ssh connection to the x2goserver without using the ssh gateway offers by my x2gobroker server. This case is fine with a Linux client. Is there a problem in my network windows configuration ? Client version is one of the last windows release (4.1.2..). I tried several versions. X2goserver and X2gobroker versions are the last from the official x2go repositories for debian/centos (broker 0.0.4.1-1 , server4.1.0.3) My command to excute x2cgoclient in windows 10 powershell "C:\Program Files (x86)\x2goclient\x2goclient.debug.exe" --broker-url="ssh://x2go-gateway.domain.fr:/usr/bin/x2gobroker --mode SSH" --add-to-known-hosts --portable --debug --libssh-debug --libssh-packetlog --disable-pulse --link=adsl X2go-gateway.domain.fr is an x2gobroker server, but also a ssh gateway to acces x2goservers on private network. You will find debug messages from the file attachment. I may just be too tired to see where is the error... Any advice, help are welcome.

Apologies - accidentally sent before completing Hi, I have a working installation of x2go, but there is some ugliness about the setup that I'd like to reduce. Any advice welcome. Here's how it looks at the moment. 1) vpn connection to the institute. 2) ssh tunnel to the workstation from the laptop 3) x2go connected to the local tunnel port This works, but we now have 3 layers of encyption. The reason for not pointing x2go directly at the w orkstation is the use of PaloAltoNetworking appliances within the institution. These do a man-in-the-middle break of ssh connections and lead to the following error from x2go: kex error : no match for method kex algos: server [diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1], client [curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1] A direct ssh login works, but always falls back to a password. Is there any configuration option possible to have x2go/libssh handle the setup in the same way that regular ssh does? That would eliminate one encryption layer. Other recommendations greatly appreciated too.

x2gokdrive and windows client
by Михайло Падалка 02 Apr '20

Yesterday I updated X2go on my Debian (4.1.0.4-0x2go1.2~git20200228.1815+9.heuler.1) and windows client (last stable from X2go download page), and saw there is an option to use x2gokdrive. I turned it on and tried to connect - but nothing worked, no desktop, no any errors etc. Is it supposed to work on windows client? -- З повагою, Михайло

Resizing remote desktop behavior
by Kees Bakker 02 Apr '20

02 Apr '20

Hey, My setup is with a Ubuntu client and a Linux server and two monitors local. The session is MATE. Xinerama extension enabled. After connection the desktop is created and I have a window (not full screen) on one monitor. Then I stretch the remote desktop horizontally, by grabbing the right side (not the corner). I want it to stretch it occupying my two monitors, while leaving a little bit on space on all sides. The Xinerama extension works quite well. The panels stay on one (local) monitor. Cool feature! What troubles me is that the height is expanded at the same time while doing the horizontal stretch. Sometimes the bottom edge even disappears off-screen. There really is something funny with resizing that it keeps moving the bottom. Even when I move the desktop window as a whole by dragging the top bar, as you would normally move windows in Ubuntu Gnome. It seems to have a strong preference to make the remote height the same as the height of my local monitor. What is extra annoying is that working remotely (thanks to X2GO!) the feedback from the remote is not immediate. So it jumps to where you don't want it to be, before you have time to react. So, the question is, how do I stop it from snapping to the local monitor screen edges? -- Kees
