 +The easiest way to gain access the Computer Science Dept. Linux machines outside of the Asprey computer lab. This gives you terminal access to the command line inside the department, and it allows you to send files back and forth to your home directory. Since it has no remote GUI, it is much faster than VNC. 
  
 +The simplest way of doing this is first to [[https://servicedesk.vassar.edu/catalog_items/270991-vpn/service_requests/new|connect to the VPN]]. Then, open a terminal on a Mac or Linux machine and type ''ssh username@mote.cs.vassar.edu'', or use PuTTY on Windows. This will provide you with a terminal on "mote", which you can use to ssh into other workstations on the CS network.

 +===== What is a Secure Shell? ===== 
 + 
 +As written on Wikipedia, 
 +> Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote shell services or command execution and other secure network services between two networked computers that it connects via a secure channel over an insecure network: a server and a client.
  
 A secure shell client allows you to connect to a remote computer. If you wish to access the Vasser CS Department Unix system outside of the lab, you will need to use a secure shell. The secure utilities correspond to older, non-secure counterparts. For example: A secure shell client allows you to connect to a remote computer. If you wish to access the Vasser CS Department Unix system outside of the lab, you will need to use a secure shell. The secure utilities correspond to older, non-secure counterparts. For example:

   * **sftp** A replacement for ftp. Ftp, the file transfer protocol, has traditionally been used to browse file systems for download, and optionally allowing uploading to the server.   * **sftp** A replacement for ftp.

-===== Common Problems ===== +

-When running emacs from a ssh client, make sure to run it as: \\ "emacs -nw"\\  instead of \\ "emacs &"\\  so that emacs knows to run as a text based interface.+
