Here is the IP of the machine : (
This is a simple scan, I don't know how to get more informations about the server. If someone can help.
Basically, I don't want to have access to commands or anything else, I need to have access to the files. Thank you.

Is this server running off of ubuntu 4? If it is, then you could probably search on or for an exploit. If you know the owner/are comfortable with open-source information gathering, then a dictionary attack with CUPP on ssh might be a solution. Again, this site is mainly for educational purposes only, so please don't try posting for help with blackhat activities on here that often.
