Hello Support I have tried installing the dev tools as per the instructions on this page; https://gluu.org/docs/gluu-server/4.1/developer-guide/script-debugging/ However, whenever I perform step 6, "Run /opt/gluu/bin/eclipse.sh" I receive the following error ``` root@adris-gluu-dv:/opt/gluu/bin# MoTTY X11 proxy: Unsupported authorisation protocol Unable to init server: Could not connect: Connection refused Eclipse: Cannot open display: MoTTY X11 proxy: Unsupported authorisation protocol Unable to init server: Could not connect: Connection refused Eclipse: Cannot open display: org.eclipse.m2e.logback.configuration: The org.eclipse.m2e.logback.configuration bundle was activated before the state location was initialized.

I have tried the trouble shooting steps. When I run the xhost command from outside the CE I get the following ``` gluu-admin@sissadrisgluuvmaedv:~$ xhost access control enabled, only authorized clients can connect INET:169.254.91.17 LOCAL: ``` If I log into the CE and run xhost I get command not found.

Do you have XWindows running on that server? What happens when you type : `xclock &` ?

I ran the xclock command and the response was to install the X11-Apps which I did. After that, I was able to run xclock, which opened the clock GUI widget. However, when I log into the gluu-server and try to run eclipse.sh I still receive the same error ``` gluu-admin@sissadrisgluuvmaedv:~$ xclock & [1] 108521 gluu-admin@sissadrisgluuvmaedv:~$ Warning: Missing charsets in String to FontSet conversion ^C gluu-admin@sissadrisgluuvmaedv:~$ sudo /sbin/gluu-serverd login Welcome to the Gluu Server!

Hi Jeremy , From logs its look like gtk issue on your machine. I think this is a problem with gtk. Check what version is installed. ```dpkg -l libgtk[0-9]* | grep ^i``` If it's not installed or is the incorrect version then do a ```sudo apt-get install gtk or do an sudo apt-get update.``` Thanks and Regards Mohit Mali

Yes, it's more like x11 forwarding issue, not Gluu Server's software. Quick google gave me [this](https://superuser.com/questions/1111900/how-to-fix-mobaxterm-x11-proxy-unsupported-authorisation-protocol) page.

Hi all, Apologies for the late reply, thank you for the suggestions regarding X11. I'll will look into X11 forwarding and post back.
