What is the hash algorithm / format used for the host key hash during connection instantiation?
by Stefan Mätje 07 Dec '20

07 Dec '20

Hi, I'm using x2go to connect from a Linux Mint (19) machine to an Ubuntu server using a RSA key over SSH. During the connection instantiation x2go presents me the following question: Der Server ist unbekannt. Vertrauen Sie diesem Host-Key? Hash des öffentlichen Schlüssels: remote.server.com:22 - d7:2e:e0:ae:27:7a:e5:33:59:6d:00:12:75:22:0a:c6:9a:10:31:a9 I. e. "The server is unkown. Do you trust this host key?" I now have problems to match the presented fingerprint hash to the host identity keys that are present on the server machine under /etc/ssh/ssh_host_*key*. When I later inspect the .ssh/known_hosts file on my Linux Mint machine (client side) I can match the public key there to the public host identity key on the server side that has the following fingerprints (displayed with 'ssh-keygen -l -E {md5|sha256} -f ssh_host_ecdsa_key'): ssh_host_ecdsa_key.pub: 256 SHA256:3vf9PbLKhlaFpff7SxpaDLyrfYJF8iJ+Px3bMzLNY2U root(a)internal.server.com (ECDSA) 256 MD5:7b:9a:76:4b:58:ce:87:bf:3f:56:41:a9:7c:f8:bf:e9 root(a)internal.server.com (ECDSA) Neither of these fingerprints can be matched to the fingerprint / hash that x2go presents to me. The MD5 hash line is similar but shorter (only 16 hash bytes aka. 128 bits that matches a MD5 sum length). The x2go hash has 20 bytes (160 bits) hash length. The question is how can I reliably match the fingerprint x2go presents to me to the right host ID hash. Am I comparing / expecting the wrong keys? Can somebody please shed some light on this issue. Best regards, Stefan

Terminating session when connection drops takes a long time
by James Bowery 18 Nov '20

18 Nov '20

As previously mentioned I have a flakey internet connection and must frequently reestablish my x2go connection but this is compounded by a problem: When the connection is momentarily interrupted getting reconnected takes a while because of strange behavior in trying to close out and reopen the x2go session: Click the x to close the window and I'm asked "No response received from the remote server. Do you want to terminate the current session?" which is not strange at all but when I click "yes" it doesn't do so immediately, but can take quite a while. Other windows pop up with additional questions depending on what I do to overcome the delay. The closest thing I've discovered to this is an issue from 8 years ago: https://x2go-user.x2go.narkive.com/4jvHBucc/session-resuming-after-disconne… Is there a configuration parameter or something I can set nowadays?

Clicking on other than window border doesn't bring it to the front
by James Bowery 16 Nov '20

16 Nov '20

I'm wondering if I'm having trouble with x2go or with X11 or my kinesthetic memory, but for the last few days, my reflexes to bring a terminal window to the front by clicking on other than its border is being defied. I have to click on the border to get it to come to the front. Disconnecting and reconnecting (even with login) does not reset this condition.

mounting local folders not working
by Bernhard J. Mayr 12 Nov '20

12 Nov '20

Hi! I am using the X2Go-Client with mounted home directories. Now the mount does not work from both clients (mac and ubuntu 20.10). While the connection is being established, there is no error message. What I have checked so far: remote user on server is in group „fuse“ on mac: enabled remote login for all users Any idea on how to fix this issue? Thanks! Bernhard

X2Go server on BSD
by Olivier 11 Nov '20

11 Nov '20

Hi, I am wondering if there are pointers on th way to port X2Go server to BSD Unix. From what I have been pocking around, it is highly dependant on Linux, using tools that are not really standard like ss instead of netstat for example. Poking in the scripts, I have not been able to go very far, so I am wondering if it is worth speding some more time or if it is a lost cause. So far, I have been using a Windows machine as a desktop, with the X terminal X-Win 32. UIt allows me a simple access to my various servers at the click of a button. Since I have changed for an Ubuntu desktop, accessomg the servers is way less simple and less integrated (because Gnome or any window manager that I have tried is grabbing so many key combination that I want to use for something else). But X-Win32 still works in wine and I can port all my Windows environment with little to no change. But I wanted to try a different X solution maybe, hence exploring X2Go. TIA, Olivier --

A couple of simple questions
by kht-lists 30 Oct '20

30 Oct '20

Recently I installed x2goserver on an Ubuntu Mate 20.04 machine and x2goclient on my CentOS 7 workstation. I configured the session with "[X] Try auto login (via SSH Agend ot default SSH key)" as I have an SSH key installed on the remote machine. It connects fine over my LAN and I find the CPU utilization on the remote machine much lower than with x11vnc which I had been using. Her are my client related questions... 1) What is the CORRECT way to disconnect from the remote machine and leave the remote session (and the programs on it) running? The goal being to be able to check back later on the status of the work which the remote machine is performing. 2) How does one connect to more than one remote machine? I have only been able to do this by loading an additional x2goclient for the next remote machine. This seems to waste a lot of real estate. I explained my adventures in detail on linuxquestions.org but did not receive any advice. https://www.linuxquestions.org/questions/linux-software-2/x2go-how-to-disco… Thanks, Ken I don't have a Swiss bank account but I do have a Swiss email address :-) Sent with [ProtonMail](https://protonmail.com) Secure Email.
