Linux Logins

Logins are required for terminal sessions or file transfers.

Accounts and Login Hosts

Logins require a Sociology Linux account. The three hosts listed below are available for login from anywhere. A login to any of these hosts always takes you to your Linux home directory.

SSH Logins

Logins require use of SSH (Secure Shell) connections from your client PC to the Linux server host. SSH connections are encrypted and quite secure. SSH is a native facility on Mac and Linux desktops. Windows users must install an SSH client.

OIT provides several Windows SSH applications for this purpose. We recommend installation of F-Secure software. The F-Secure product installs two components. The F-Secure SSH Client provides a terminal function, and the F-Secure SSH FTP Client provides a file transfer facility.

Linux Graphics Display Facility

SSH cannot display graphical output (such as an interactive SAS or Stata session) from a Linux host. This requires a separate facility called an X-Windows server, to which SSH can hand off graphical output. X servers are native to Mac and Linux desktops, but not to Windows. OIT distributes a product called X-Win32 to fill this need.

There are several important X-Win32 considerations:

Login Specifics

When logging in from a Windows PC:

  1. Preload X-Win32.
  2. Load your SSH application.
  3. Select the connect option.
  4. Specify the desired host.
  5. Enter your userid and password to complete the login.

When logging in from a Mac or Linux PC:

  1. Open a terminal window.
  2. When your PC login ID is the same as your Sociology userid, specify at the terminal prompt: ssh -X <hostname>

    • where <hostname> is from the list above

  3. When your PC login ID differs from your Sociology userid, specify at the terminal prompt: ssh -X <userid>@<hostname>

    • where <userid> is your Linux userid and <hostname> is from the list above

The -X permits forwarding of graphics to the X-server on your local machine. Omit this parameter when graphics are unneeded.
