Kali is basically a flavor of Debian. I installed my .deb file with command line DPKG command. Installer proceeds, finishes without error. Service shows status as ? rather than + or -. Not sure how to troubleshoot connection issues. Any ideas on why it's not showing up in my remote access list?

I installed on ubuntu 16.04 using similar approach and it works fine. Not sure what the issue with Kali is that's causing it, but I'm trying to avoid shoveling Xwindows over SSH if I can...

What's in the client's logfile? By default it should be found at /var/log/screenconnect-xxx

Just tailing the last 100-150 lines or so should help.

Also, is Java installed?

Yeah, I checked Java. It's installed but something is clearly wrong. Here is the Java info:
Quote:
openjdk version "1.8.0_102"
OpenJDK Runtime Environment (build 1.8.0_102-8u102-b14.1-2-b14
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)


Tailing the client logfile reveals clear issues, but none I'm knowledgeable enough to sort out:

Hmm, what version of the ScreenConnect client are you attempting to install onto the machine?

I am having the same issue. .deb screen connect package installs fine and appears to be running. When I connect I just get a black screen. The reboot option on the Misc menu does work.

I'm running 64bit Kali 2016.2 and ScreenConnect 6.1.12292.6236.

What version of Java is installed on the Kali guest?

If you're using a variety of Java 8, you're likely running into the issue described in the following technical bulletin:

"When you connect to certain desktop environments on Linux, elements of the desktop are not displayed. This issue is due to a bug introduced in Java 6. That bug was fixed in Java 7; however, due to some stability issues in Java 8, that fix was reverted."
