LAME

Hello! I have some issues with this machine… I just started trying to learn this and have done a few courses at the academy. Now i wanted to start challenge my self and decided to give it a crack at some machines. But now i have some real troubble. I gave it a few tries myself but hit a wall. Then i decided to look at some walkthroughs. But neither the metasploit or phyton works. The metasploit runs but say: [*] Started reverse TCP handler on 10.10.17.226:4444 [*] Exploit completed, but no session was created. And the python says: [*] CVE-2007-2447 - Samba usermap script [+] Connecting ! [+] Payload was sent - check netcat ! Now the netcat wont show me anything.
