Bug#1003: x2goclient sshd (for folder sharing) weak host key
by Florian Wicke - Hetzner Online GmbH 25 Feb '16

25 Feb '16

Package: x2goclient The sshd (sshd.exe) spawned by x2goclient for things like the folder sharing is creating a DSA HostKey. Even if this sshd is only listening on localhost and is accessed through the ssh tunnel from the X2Go server this might lead to connections errors if the ssh_config of the server is configured to not allow connections to these weak (1024 bit) DSA HostKeys. I would advice increasing this to at least 2048 bit RSA host keys or even elliptic curve host keys if available.

Bug#1002: Windows: Folder and Printer Sharing broken since update to cygwin bundle 20160121-1
by Mike DePaulo 25 Feb '16

25 Feb '16

package: x2goclient version: 4.0.5.1 tags: build-win32 Ever since I updated the Cygwin bundle to version 20160121-1, which includes an openssh update: openssh 6.8p1-1-x2go1 -> 7.1p2-1-x2go1 (security update) Folder and printer sharing has been broken. Specifically, the sshfs mounts never take place on the server. The sshd.exe process is running though. I have been talking with Ionic on IRC about this. The most logical next step for debugging this is for me to modify the behavior of x2goclient's --debug on Windows to pass an option like this to sshd.exe: -E /path/to/debug/log

Bug#838: control-alt-arrow keys
by Robert Dinse 24 Feb '16

24 Feb '16

Package: x2goagent I am using Ubuntu 14.10 with Mate Desktop with multiple work spaces. If I use Remmina with NX plugin, the control-alt-right/left arrow keys work to switch work spaces even when I'm up on a remote desktop. With X2Go, it usually doesn't work, except if I use control-alt-M to minimize the session then restore it, the keys will usually work thereafter. Remmina has a way to toggle this behavior, a little pull down at the top with a keyboard symbol. If it's down, the control-alt-arrows go to the end application allowing me to switch work spaces on the remote desktop, and if it's up they go to the local desktop. It would be nice if x2go had a similar facility but if not it would be better for that key sequence to always act locally since I can switch work spaces remotely by using the mouse but can not locally because the switcher is hidden by the remote desktop x2go is displaying. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Bug#847: Cleanly Terminating a Fullscreen Shadow Session Locally doesn't Work on MS Windows

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 package: nxagent When trying to terminate a shadow session running in fullscreen mode on a MS Windows client, Alt-Tab gets passed to MS Windows, so one can reach the X2GoClient control buttons (folder sharing, pause, terminate), but clicking pause or terminate doesn't do anything.

Bug#898: Weird colors and image issues on ppc64le Ubuntu 14.04
by Mihai Moldovan 23 Feb '16

23 Feb '16

Package: nx-libs Version: 3.5.0.29 After building and installing X2Go packages on Ubuntu 12.04 ppc64le some months ago, I experienced the following strange behavior(s): - image colors were distorted sometimes (but sometimes not) - instead of brown, pink was shown - images (PNG? SVG?) didn't load or show correctly. Colors were way off (see above) and mostly only contours drawn, if even that. - scrolling in a scrollview (e.g., XFCE's settings manager(?)) sometimes forced a correct redraw of images, but mostly only partitially - hovering over an image broke it visually again - mouse cursor either disappeared completely or was replaced with a block (what seemed to be random data converted to an image) I have not done any debugging on these issues yet. Mihai
