SSH (Secure Shell) access clients
SSH is the required way to connect with the U-System. SSH uses encryption to prevent eavesdroppers from reading information, such as your password, from the network. All SSH-type software allows for secure communication, replacing the vulnerable utilities like telnet, rlogin, ftp and rcp. You can find free SSH software at the following places:
SSH For Windows
Download the SSH clients from Software Licensing There are three site-licensed SSH clients used for secure access to U-Systems: puTTY, WinSCP or Tera Term. You can download these clients from the Software Licensing page. puTTY is the command line and tunneling client for SSH. You use puTTY for secure computing with your UNIX account. WinSCP is the graphical Secure File Transfer (FTP) client for SSH. You use WinSCP for secure file copies to and from your UNIX account. Tera Term Pro is a command line and tunneling client with a page printing feature. This tunneling client is preferred for use with PSOS.
SSH For MAC
Mac OS X comes with SSH as part of its operating system but you must use OS X's Unix interface to take advantage of some of it. There are several ways to connect and transfer files to and from the U-System. Each method's user-friendliness and shortcomings are noted where relevant. To use graphical applications like Fetch, and older versions of Dreamweaver (4 and MX) you will need to tunnel your file transport through SSH. For Mac OS X Fugu, is an easy, secure, free alternative to Fetch. DreamweaverMX 2004 (OS 10.2.6) uses SFTP.
- The command ssh is used to log in to remote hosts, replacing rlogin and telnet.
- SSH software also includes the commands scp and sftp, which replace cp and ftp for copying files to and from the U-System.
- Some applications like Fetch have their own file-transport mechanisms but they are not secure so they must tunnel SSH to get to remote hosts that are protected by SSH.
- You might consider Fugu as a graphical alternative to Fetch for file transfers.
SSH For Unix
There are two recommended SSH clients for Unix based platforms. 1. Open SSH, which is the preferred option 2. PuTTy, which you can download the source code from Software Licensing (NetID Login Required)
Web Based SSH
Web based SSH is a way to use SSH through a web browser. The following directions describe how to use SSH with your web browser to connect the U-System.
