If you are using Mac or Linux you can use scp or even more friendly, download an FTP client, if you are on Mac I recommend you to use CyberDuck. In the end all you need is an FTP client. If you are on Windows I would recommend you Filezilla.
What OS are you in?
Since you are in Ubuntu, try this:
Connect to a file server
+ In the file manager, click File ▸ Connect to Server.
Enter the server address, select the type of server, and enter any additional information as required. Then click Connect. Details on
server types are listed below.
For servers on the internet, you can usually use the domain name. For
computers on your local area network, however, you may have to use the
computer's numeric IP address. If the other computer is running
Ubuntu, see Find your IP address to find that computer's internal IP
address. Otherwise, check the help on that computer.
A new window will open showing you the files on the server. Browse the files and folders just as you would for local files and folders.
