Ubuntu has a build-in utility lets you to access network filesystem on your desktop .In this tutorial I’ll using SSH protocol because it is much more security than FTP.
Navigate to Places–>Connect to Server… to open up it.
Change Service type to SSH in following screen.In Server field type the fully qualified domain name or the IP address of the remote computer.Leave the Ports field blank.
Enter the home directory in Folder field,if it’s left blank you will be dumped into the root directory.Enter the username in User Name field
If you select Add bookmark and enter a bookmark name,next time you connect to the remote filesystem you won’t have to go through all of these steps.
Click Connect button,a window pops up prompts you to enter the password.
When you access to the folder,you can umount it by right click on the desktop icon and select Unmount Volume in the pops up menu.
