class Termrequire:
host = socket.gethostname()
port = 3333 # fake numeral for the moment
class Clientrequire:
host = socket.gethostname()
port = 2222 # fake numeral for the moment
#CORE REQUIREMENTS OF PROGRAM:
### 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
# server ip will be displayed every connection at version 2.0
# terminal attacker socket object creation
t = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# terminal attacker socket binding
t.bind()
# terminal attacker socket listen
t.listen()
# client socket object creation
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# binding information with s.bind method
s.bind()
#listening for connections with s.listen method
s.listen(1)
# server_functionality waits for terminal shell and then gets client information connectivity
def func4client():
s.accept()
# terminal functionality for attacker - I will definitely customize it soon. Maybe tkinter?

# simple client server
#### Note:
- Run **`server.py`** first.
- Now, run **`client.py`**.
- verify the output.
