Getting started at TACC

Getting to a remote computer

The terminal window

• Macs and Linux have Terminal programs built-in – find it now on your computer
• Windows needs help
  • Putty – http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

    • complicated to install

SSH

ssh is an executable program that runs on your local computer and allows you to connect securely to a remote computer.

On Macs, Linux and Windows Git-bash or Cygwin, you run it from a Terminal window. Answer yes to the SSH security question prompt.

ssh your_TACC_userID@stampede.tacc.utexas.edu

If you're using Putty as your Terminal from Windows:

• Double-click the Putty.exe icon
• In the PuTTY Configuration window
  • make sure the Connection type is SSH
  • enter stampede.tacc.utexas.edu for Host Name
  • click Open button
  • answer Yes to the SSH security question
• In the PuTTY terminal
  • enter your TACC user id after the login as: prompt, then Enter

The bash shell

You're now at a command line! It looks as if you're running directly on the remote computer, but really there are two programs communicating: your local Terminal and the remote Shell. There are many shell programs available in Linux, but the default is bash (Bourne-again shell).
