Ok I enabled the TCP port.

This is the output now of `netstat -al | grep 6000" on the physical machine:

(standard input):4:tcp        0      0 0.0.0.0:6000                
0.0.0.0:*                   LISTEN
(standard input):39:tcp        0      0 :::6000                     
:::*                        LISTEN
(standard input):45:tcp        0      0 ::1:6000                    
::1:58897                   TIME_WAIT
(standard input):46:tcp        0      0 ::1:6000                    
::1:58899                   TIME_WAIT
(standard input):47:tcp        0      0 ::1:6000                    
::1:58896                   TIME_WAIT
(standard input):48:tcp        0      0 ::1:6000                    
::1:58898                   TIME_WAIT

while in the virtual machine (where the command is `netstat -al | grep 
6010`, apparently it listens on that port):

(standard input):8:tcp        0      0 127.0.0.1:6010          
0.0.0.0:*               LISTEN
(standard input):14:tcp6       0      0 ::1:6010                
:::*                    LISTEN

Still can't get it to work as it should though.
