File Transfers

Fugu is a graphical front-end to the command line 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. It allows you to take advantage of SFTP's security without having to sacrifice the ease of use found in a GUI. Fugu also includes support for SCP files transfers, and the ability to create secure tunnels via SSH.

  3. Login to a UNIX machine (example: eos.tamu.edu).

    The -X option tells SSH to allow programs to forward and display their graphical interfaces. This is known as X11 forwarding.

  4. To verify that X11 forwarding is working, type the following command:
    xterm

    If a new xterm terminal window for the remote system pops up, then X11 forwarding is working correctly.
