-### host ip = server ip
-### potential connection hosts info (host, port)
-### user.config
-### user.config
-# using SERVER for connections and linux meterpreter sessions
-# SERVER DETAILS:
-    #5 client availability for pivoting #although that is not yet available in a regular form of
-    #exploitation  - we have to go with what we have.

-# #learnmore - USER_CONFIG
