Welcome to the CS105 EdLab host!
Please read the
The Computer Science Educational Laboratory sports 35 Linux PCs and 20 Windows PCs, all supported by several servers. The Edlab is located in rooms 223 and 225 in the Lederle Graduate Research Tower (LGRT) which can be found in the middle-top of campus on this map. The Windows Edlab is located in LGRT 215.
The EdLab is shared by many classes each semester for middle and upper level Computer Science classes, and is maintained by the Computer Science Computing Facility. If you have any suggestions or comments for improving these pages or the Edlab, please send mail to firstname.lastname@example.org
The following classes for the Spring 2007 semester require the EdLab for use. Click on any class to access its home page. Click on any TA to send him/her mail. Not sure which class is which? Here are the current course descriptions.

EdLab UNIX User Notes
Please read the EdLab User's Introduction and Guide to Unix if you have questions on using the EdLab UNIX machines.
There are hard copy versions of this document in the EdLab. Please do not print this document.
EdLab e-mail setup
All new edlab accounts will have a ~/.forward file redirecting mail to the user's official university email address. Users can remove this file and receive email in the edlab. The mail forwarding can be changed using this web interface from any host on the Umass network.
All Edlab users should be using an IMAP client to read their e-mail -- local mailboxes don't exist on the Linux systems. PINE and Mozilla are two of the mail clients which support the IMAP protocol. The default PINE setup is already configured to use IMAP (this is not the case for Mozilla). If you need to configure the IMAP client yourself, the IMAP server is edlab-mail.cs.umass.edu.
EdLab Web Server Statistics
Statistics for the UMass Computer Science Department Education Lab Web Server (edlab-www.cs.umass.edu) are compiled and updated weekly. We are currently using analog written by Stephen Turner at the University of Cambridge Statistical Laboratory to process our Web Server logs.
Remote access to EdLab hosts
All of the EdLab machines are connected to the Internet. Hostnames are as follows:
The use of ssh is required for accessing all of the EdLab systems from a physical location other than its console (i.e. "network" or "remote" logins.).
The SSH protocol is intended for use as an endpoint-to-endpoint secure replacement for the Berkeley's "R" commands (rsh, rlogin, and rcp), 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:
The edlab-ftp server provides anonymous access for downloading course material; All other plaintext FTP access has been disabled on the EdLab systems. Users can use scp or sftp clients to connect to any of the elnux systems.
Where to find SSH client programs:
Student WWW pages
Students in the EdLab may program their own web pages if they choose. Each student has a default web page: ~/public_html/index.html. Edit your home page and add your personal information.
The URL for a student's home page is:
For information on HTML programming, please see one of the many tutorials available on the web, such as the W3 General HTML page.
