remote access/using ssh and scp

If you want to connect to the CS machines from your dorm room or home computer, you will need an ssh client on your machine. ssh stands for Secure SHell.

If you want to transfer files to or from the CS machines, you will need either scp or sftp, which are secure versions of the copy (cp) and file transfer (ftp) programs.

How to get and use these programs depends on what operating system you are using.

Linux/Unix

Linux systems probably already have ssh and scp installed (if not, look for an openssh-client package to install.

Open a terminal window and run ssh from the command line:

    ssh -X uname@lab.cs.swarthmore.edu

You should change uname to your ITS username (e.g., hpotter1).

Mac OS X

Mac OS X also comes with ssh installed. Open a terminal (in Applications/Utilities) and try this:

    ssh -Y uname@lab.cs.swarthmore.edu

Again, replace uname with your ITS username (e.g., hpotter1).

If you intend to run a program on the CS machine that opens a new window back to your computer (e.g., a graphics window, a browser, etc), you'll need to install X11 (XQuartz) for Mac.

Windows

For Windows machines you need to download the putty ssh client, and WinSCP if you want to transfer files:

If you intend to run a program on the CS machine that opens a new window back to your computer (e.g., a graphics window, a browser, etc), you'll need to install Xming.
