To access course files and software you will need to log into Stanford's Unix machines, either in person or remotely.

• Which Unix machines to use: Not all of Stanford's Unix machines are identical. We recommend using the Corn machines, and we will be grading your programming work on those machines.

• Connecting to the Stanford machines using SSH: Windows users can use SecureCRT available on the Essential Stanford Software page. Mac users can use the command-line ssh tool from the Terminal.

• Using the Unix shell: You should be familiar with Unix since CS107 is a prerequisite for CS145, but if you need a refresher, here's a Unix Command Summary including a link to a Unix tutorial.

• Transmitting files to your AFS directory: You may prefer to do some of your work on your own computer, then upload files to your AFS home directory (the file system Stanford uses). Everything must eventually be in the Stanford file system since that's the only way the submission scripts can access the files. To upload, the Essential Stanford Software page should lead you to the right software, enabling you to use SFTP or SCP to transmit the files. Windows users can download SecureFX and Mac users can download MacSFTP from the Essential Software site. Mac users can also try the command-line scp and sftp tools. Be sure to check the "Learn More First" links on the Essential Stanford Software download pages for directions on configuring the software.
