If you already have a Unix account from other courses, your username and password should be the same. The Computer Science (CS) Department maintains a laboratory on the third floor of the Science Building, near the CS Department Office. In that lab are unix systems accessible from the Internet, and Windows XP workstations accessible in the lab. You must apply for a unix account following the instructions on the white board in that lab. You will need your student ID and your student card. It will also help if you bring evidence (e.g. a WISER printout) that you are enrolled in CS/IT114.
In a day or less, you will have a unix account approved. As part of the unix application process you will be asked to choose a logon name, and after account approval this will also allow you to log on to the Windows machines in that lab in case you do not have a machine of your own. Our unix systems are also provided with the Java development environment and with emacs, and those are possibly an even better to learn, programming environment if you don't have a computer at home on which you can install Java. That's because you can reach them from the internet (e.g. from the Healey Library computer labs, a computer in your public library, or any other place with internet access.)
Note that the lab operator must be in, in order to check your ID and process your request.

get a CS account for this course (it114) on Unix system. (applying for this course on Unix system). The full instruction is on the board in the Unix lab. You also can ask the operator to help you.
NOTE: ALL THE STUDENTS SHOULD GET AN ACCOUNT FOR THIS COURSE ON UNIX AS it114, EVEN IF YOU ARE REGISTERED AS cs114. it114 and cs114 ARE TWO DIFFERENT LABELS FOR THE SAME COURSE.
In CS114/IT114 we require that you turn in your homework on unix, and that your programs run correctly in the unix environment. You actually could accomplish this entirely by using unix, which you can do remotely from the internet. In any case, if you are programming at home, remote use of the CS unix hosts will require you to have two kinds of software on your home machine: Secure Shell (ssh) and Secure FTP (sftp). There are plenty of free ssh clients available for Windows. Macs have them preinstalled (but they may have to be started from a terminal window). The Windows PCs in the Unix labs will already have ssh and sftp on them. For students who want to install ssh and sftp on their own Windows PCs, I recommand them to use sshwinclient.
ssh is used to open a secure remote terminal window. sftp is used to transfer files from your machine to a remote machine.
Once you have installed sshwinclient, you will need to configure them using one or more of these parameters.
| ssh configuration parameter | value |
|---|---|
| protocol | ssh |
| ssh version | 2 |
| ssh port | 22 |
| host | users.cs.umb.edu |
| user name | your unix user name |
| password | your unix password |
