The Computer Science Educational Laboratory is only accessible remotely (with the exception of discussion sections or office hours). The EdLab resources are shared by many classes each semester for undergraduate and graduate level Computer Science classes, and are maintained by the Computer Science Computing Facility. The machines are located on the CICS network and accessible remotely as well as a small number of Mac desktops in the Lederle Graduate Research Tower (LGRT) Room 223. EdLab CoursesThe classes below for the Fall 2024 semester require the EdLab for use. Click on any class to access its home page. Not sure which class is which? Here are the current course descriptions
Remote access to EdLab hostsThe EdLab Linux machines are connected to the Internet and you need to do the following to setup up your access. Instructions are below and detail instructions are linked here.
Once you have Completed the steps above, please review these instructions for logging in here For Linux log into machine elnux.cs.umass.edu : this will put you on one of the linux hosts elnux1.cs.umass.edu, elnux2.cs.umass.edu, elnux3.cs.umass.edu, or elnux7.cs.umass.edu. PLEASE NOTE:
The SSH protocol is an endpoint-to-endpoint secure connection for remote command-line login, but in order to achieve that security you must start the ssh client from your local machine. (I.e. the one at which you are physically typing.) On UNIX, the SSH protocol is implemented by:
NOTE: If your username on your local machine is not the same as your edlab username you will need to specify the username when using these commands.
For example: Note: if you wish to remotely use programs that have a graphical interface, you will need to "tunnel" your X-windows session back to your remote host.
Important:For X-tunneling to work, you must also have either X-Windows or XQuartz installed on your local machine. Where to find SSH client programs:
EdLab Software and Unix NotesCheck the Edlab Software Notes for information on using specific software packages in the Edlab. Please read the EdLab User's Introduction and Guide to Unix, and the quota and storage management guidelines if you have questions on using the EdLab UNIX machines. Please review these examples of logging in with Two Factor Authentication for SSH, SCP, SFTP and VSCode. Read this for examples of automating a script with Two Factor Authication. Usernames and Passwords: Your username will be the same as your UMass username. The initial password should be given to you in class or by a TA. If you cannot log in send email to system@cs.umass.edu.
OSX Machines in the EdlabIf you log into the console of one of the Edmac machines running OSX, you will have a different home directory then in Linux. The home directory in OSX will be accessible from any edlab system booted into OSX The ~/linux directory in OSX will point to your linux home directory. When logged into an Edlab Linux system, the ~/OSX directory will point to your OSX home directory. In Either linux or OSX your course directories will be accessible as ~/csxxx
EDUROAM Wireless networkingEduroam allows UMass Amherst students, faculty, and staff to obtain free wireless connectivity at participating institutions in the U.S. and abroad. A valid umass account is required for connection. Getting ConnectedFollow the Umass IT instructions for connecting to Eduroam. Once this is configured you can connect to eduroam in the CS spaces. Student WWW pagesStudents in the EdLab may program their own web pages if they choose. Each student has a default web page (from linux): ~/public_html/index.html. Edit your home page and add your personal information. The URL for a student's home page is: https://www-edlab.cs.umass.edu/~username For information on HTML programming, please see one of the many tutorials available on the web, such as the W3schools HTML Tutorial page.
