Boa HTTPd 0.94.14rc21 arbitrary file exploit not workig

[Le@rner]

hi Guys, 

One of your server is using Boa HTTPd 0.94.14rc21, I was reading regrading the arbitary file exploit and tried to see if it's working and it's not. 

this is the exploit page. 

https://www.exploit-db.com/exploits/42290/

However, when I try on server using telnet. I am getting Connection closed by foreign host.

And if I try to exploit this using browser as mentioned below 

http://192.168.0.1:81/../../../../../../../../var/log/messages

 

it says 

404 Not Found

The requested URL /var/log/messages was not found on this server.

 

Also, my question, is even if I get access to files,  how is it possible that I can get access to root password?
