[X2Go-User] Can't access X2go through router
Bill, could this be your problem? https://wiki.x2go.org/doku.php/doc:faq:start Known Issues Can't login to x2goserver with an ECDSA key Currently, older versions of the ssh library used by X2Go called libssh are unable to work with ECDSA keys. However you may use an RSA key - if you need to - or go with the SSH default authenticating method using the remote user's password. SSH Login issue If you already use OpenSSH to get a shell on your x2go server, you may get this message when trying to connect with x2go: The host key for this server was not found but an othertype of key exists. An attacker might change the default server key to confuse your client into thinking the key does not exist This is related to the ECDSA host key (related to the previous FAQ entry - although there is a subtle difference between host and client keys.) To solve this issue, you can disable ECDSA keys on your OpenSSH server configuration, by commenting the following line in /etc/ssh/sshd_config file: #HostKey /etc/ssh/ssh_host_ecdsa_key Then restart the SSH service. Now you should not get the error message anymore. ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user
[X2Go-User] problems connecting to x2go server
I run a personal server with x2go and I've used it for years with no problem. I can currently ssh fine, but x2go does not work. I've tried removing .x2go from /tmp and /home/paul. I've recreated the user database: rm -f /var/lib/x2go/x2go_sessions x2godbadmin --createdb None of this has worked. Removing and reinstalling seem to work, but it's now back to the same error. I have turned up logging and everything seems to complete properly. When I run the client with a --debug flag I get this, with the final 2 lines repeating: Info: Proxy running in client mode with pid '22689'. Session: Starting session at 'Mon Nov 20 14:35:24 2017'. Info: Using abstract X11 socket in kernel namespace for accessing DISPLAY=:1. Info: Connecting to remote host 'localhost:37964'.

Re: [X2Go-User] ssh-keygen.exe loads the processor every time the client starts

For more information and the rationale for this change, refer to the release announcement: http://lists.x2go.org/pipermail/x2go-announcements/2017/000302.html The release announcement talks about 2048-bit keys being generated while this indicates that even stronger keys are being used (which in turn increases the time to create them). I think for slow clients this is too much. At least the admin should be able to decide about the required security, not the maintainer. So what about staying as is by default but providing a possibility to pre-generate keys for those connections.

[X2Go-User] rstudio menus not displayed && qtcreator crash
Hello, I have two problems with two IDEs. 1) For R programming I use Rstudio.I am starting mate-terminal via x2go, and then execute rstudio remotely. It displays well, apart from the fact that pull-down menus are not displayed. They got highlightedwhen clicked, but nothing more. This is the only program which has this issue that I am aware of. Warning messages are as follows: QXcbConnection: Failed to get the primary output of the screen Could not initialize OpenGL for RasterGLSurface, reverting to RasterSurface. 2) For C++ I use qtcreator. It crashes immediatelywhen run via x2go: $ qtcreator failed to get the current screen resources Could not initialize GLX Aborted 3) Moreover mate-terminal window is not resizeable Versions: server: Latest Heuler 64bitfor Debian buster client: x2goclient 4.1.1.0 64bit for Arch Linux, running plasma desktop Thanks, Piotr ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user
