Installing and Configuring Fugu

Installing Fugu

Fugu is a graphical frontend to the commandline Secure File Transfer application (SFTP). SFTP is similar to FTP, but unlike FTP, the entire session is encrypted, meaning no passwords are sent in cleartext form, and is thus much less vulnerable to third-party interception.

If you do not already have Fugu installed, you can download it from the University of Michigan's "Research Systems Unix Group" site, located here:

Download the .dmg of the latest version to begin the installation. Once the .dmg is downloaded, follow the instructions to install Fugu:

  • double-click it to open the installer
  • when the application finishes unpacking, open Applications by clicking Finder on the dock, click Go on the title bar, then click Applications
  • drag the icon into the Applications area - this will copy the Fugu program files to Applications and complete the installation

Using Fugu

Once installed, follow the instructions below to begin using Fugu:

  • open Fugu by clicking “Finder” on the dock, select “Applications” under the “Places” heading, then double-click “Fugu”

  • once Fugu is opened, enter the machine name you would like to connect to in the “Connect to:” field. If you do not have a Facilitized Linux machine to connect to, you can use our general purpose machine, which can be reached at “”
  • enter your SCS Kerberos username in the “Username” field
  • enter “22” in the “Port” field

  • if this is a machine that you will be connecting to multiple times, you can click the “Add to Favorites” button to add the machine to the drop-down list in the “Connect to:” field
  • click the “Connect” button

Note: if this is the first time you are connecting to a machine, you will be prompted that the authenticity of the host cannot be established.

If this is the first time you are connecting to a machine, it is OK to click “Continue”. If this is a machine that you have already connected to (and no changes were made to the machine), you should click “Cancel” and contact the Help Desk.

You will then be prompted for a password – you should enter your SCS Kerberos password, then click the “Authenticate” button. Once connected, the program looks and works similar to an FTP client. Your local file system is listed in the left window, and the remote file system (the machine you are connected to) is located in the right window. The right window will display your Linux home directory, which by default is your AFS user space. You can also browse the remote machine by clicking the drop-down menu at the top of the remote (right) window and clicking “/”. To get back to your AFS user directory, it is easiest to click the “Remote Home” button in the upper-right corner of the Fugu window.

You can also view general Fugu usage instructions by clicking “Help” in the title bar, then click “Fugu README”.

If you need to connect to a different machine, click the “Disconnect” button to close the connection and navigate back to the main Fugu screen. When you are finished using Fugu, you can click “Fugu” in the title bar, then click “Quit Fugu”.
