1. Agenda Overview of Seneca Computer System File Servers / Student Computer Accounts Telnet application How to Logon to Learn / Phobos accounts How to Change your Password

2. Computer Networks Personal computers that are not connected to other computers (via network cards) are referred to as “stand-alone” computers. Institutions such as colleges find it more economical and efficient to connect up personal computers to form a computer network

3. Computer Network File Server (Central Computer) Terminal (Client)

4. File Server A file server is a powerful centralized computer system with an operating system that allows multiple users to access software applications and data files. The file server may also provide other important services such as network printer management and connection to other networks (Internet)

5. Computer Networks Computers connected to form a network over small geographic locations (such as a building or city) are referred to as Local Area Networks (LANs) Local Area Networks can use modems or routers to connect up to other LANs from far distances to form Wide Area Networks (WANs)

6. Advantages of Computer Networks Economical Ability to share hardware devices such as printers and scanners Efficient Ability to communicate among users Efficient method to maintain and upgrade software (I.e. one copy of software on file server - therefore, only upgrade one location) Ability for users to share files

16. What is the Telnet Application? Unix systems such as PHOBOS were originally designed to accommodate “dumb terminals” which were simply monitors and keyboards directly connected up to network Telnet allows the server to “think” that the user’s personal computer is a “dumb terminal” A common type of “dumb terminal” was Digital Equipment corporation’s VT100.

17. Telnet Application To launch or “run” the Telnet application from the Seneca computing lab, point and click onto the application “telnet” on the Windows 95 desktop You can obtain a free version of Telnet application for home use. SSH Secure Shell Access (More to come)

18. Open Session For all Telnet applications, you must specify which server that you will connect For this Telnet application, you must point and click onto the File menu, select Open and type the server name (such as phobos). If you are logging in from another ISP you must provide the full domain name of the server (such as phobos.senecac.on.ca)

19. Logging Onto Your Phobos Account After you connect to the phobos server, you must type in your username (should be on your Seneca “one-card”) and your password. The password will be provided to you by an e-mail message in your LEARN account. It is important to get your LEARN account as soon as possible!

20. Protecting your Computer Accounts It is important to assign an appropriate password to prevent unauthorized access to your computer accounts. Concerns regarding unauthorized use: Illegal Activity Suspension of account Loss of data / Copying of assignments

21. Password tips Avoid easily detected passwords such as names or a series of numbers. Use phrases and take the first letter of each word For example: Autumn leaves Turn red, yellow, orange
