[Metasploit Autopwn Automated]
So Fast-Track after looking for exploits shows that on specified IP there are 152 open connections, which is good.

Now when I type sesseions -l -v I can see all open connections.

But every time I write sessions -i (id of open connection) I get:

Starting interaction with (id of open connection), and then

Command shell session (id of open connection) closed.

Is that mean host is behind firewall or smth?
