apologize for the usage of words, but you are a newb...you copied that right out of the readme...even in the same order... first of all, hobbit does not want some newb using his program...if you really want a shell, the syntax:
nc.exe -L -d -p 23 -e cmd.exe
then to connect:
telnet 127.0.0.1 23
*Note-Netcat does not open the physical program "cmd.exe" on the remote computer. It instead, creates an open port on the system to connect to, to receive a command shell...newb...
