SSH provides remote, text-based access to Unix systems. It is a secure replacement for Telnet, with several additional features.

Availability

SSH may be used to access all Unix (Linux/Solaris) systems in the Design Center

Client-side Preparation

Depending on the operating system used on the computer you're connecting from, you may or may not need to install an SSH client first.

  • Windows: No client provided. Download the PuTTY Windows Installer Package
  • OS X: Built-in client. Simply run 'ssh <options>' from a terminal.
  • Linux: Built-in client. Simply run 'ssh <options>' from a terminal.

Connecting

  • Command-line ssh:
$ ssh username@host
user@host's password: <password>
  • PuTTY
    • Host Name: <host>
    • Click "Open"
    • Login as: <username>
    • Password: <password>

NOTE: The first time you connect to a host, you will be asked to accept that host's key. Once you do, any future connections to the same host will verify the saved key against the key offered by the host. The point here is to protect you from someone intercepting your connection. If you ever get a warning saying that the host key has changed, do not connect. Instead, contact us and let us know what happened.

Available hosts

Any Unix system in the Design Center may be accessed via SSH through its fully qualifed domain name. (ie, <hostname>.engr.scu.edu or <hostname>.dc.engr.scu.edu)

For your convenience, we provide two aliases which will select a random machine of the named type:

  • Linux: linux.dc.engr.scu.edu
  • OS X: osx.dc.engr.scu.edu

Example sessions

  • Command-line ssh:
$ ssh username@linux.dc.engr.scu.edu
username@linux.dc.engr.scu.edu's password:
[username@linux ~]$
  • PuTTY:
Enter the hostname and click "Open"
Enter the hostname and click "Open"

Enter your username and password

Enter your username and password
Enter your username and password
