SSH (Secure SHell) is a network protocol which provides a replacement for insecure remote login and command execution facilities, such as telnet, rlogin and rsh. SSH encrypts traffic in both directions, preventing traffic sniffing and password theft. SSH also offers several additional useful features:
• Compression: traffic may be optionally compressed at the stream level.
• Public key authentication: optionally replacing password authentication.
• Authentication of the server: making ”man-in-the-middle” attack more difficult
• Port forwarding: arbitrary TCP sessions can be forwarded over an SSH connection.
• X11 forwarding: SSH can forward your X11 sessions too.
• File transfer: the SSH protocol family includes two file transfer protocols.

This tutorial demonstrates how to use the SSH Secure File Transfer client for Windows to copy files from a local computer to the Student Organizations Server. The example uses http://www.clubs.psu.edu/up/clubs_example/, as the Web address for an example organization at University Park. Organizations that use http://www.greeks.psu.edu/ in their Web address have “up” as their campus code. A fraternity with a Web address of http://www.greeks.psu.edu/ifc/aaa/ has the directory path /clubs/up/aaa.

Secure shell (SSH) can safely be called one of the rare successes in which a more secure technology has largely replaced a less secure but entrenched tool: telnet. We perform a market analysis to determine how and why SSH succeeded despite the existence of an entrenched legacy tool while similar technologies such as secure file transfer protocols have been far less successful. We show that network externalities, usually a first order effect, were not a significant factor impeding the adoption of SSH, and that SSH offered equivalent functionality and greater ease of use. We argue that these factors were the primary consideration in the willingness to change.

In the interest of security and information integrity, Rutgers University has implemented several new changes in the ways to upload, share, and send files via your RCI account. Files must be transferred via secure means; you will no longer be able to upload files via programs such as CuteFTP or WS_FTP. SSH Secure File Transfer is the default program will you find available on all university computers.

The unix operating system consist of three parts: the kernel, the shell and the programs. The kernel is the heart of Unix, it allocates time and memory, handles file operations and system calls. The shell acts as an interface between the user and the kernel. The shell is what you are typing to at the Unix prompt after you log in. Basic Unix Knowledge o Login o Find out default shell, change to tcsh ! chsh, /bin/tcsh o SecureCRT, Cygwin ssh ! Connect to bluepig.brynmawr.edu o man (RTFM) ! man (women) !

With an RCI account, you are also allotted a certain amount of web storage space which you can use, for example, to distribute material to a class. Before you can begin sharing files, though, you will need to set up a certain folder on your account, called public_html. public_html is the default name for directories on all Rutgers systems that will include files to be shared over the web, which can be loaded up in any web browser.
