Presentation Transcript

  1. Establishing Dial-up Connection to the Internet Using Windows 9x • Install and configure the modem • Configure Dial-Up Adapter • Configure Dial-Up Networking • Install applications software to use the Internet

  2. Configuring Dial-Up Networking

  3. Configuring Dial-Up Networking

  4. Cable Modem and DSL Connections to the Internet • Cable modem • Provided by service provider • Has a connection to the TV cable system of your home that connects to the ISP and an Ethernet port to connect to your PC • Ethernet cable connects the cable modem to a network card installed in your PC • DSL • A device sits next to your PC, which connects to the DSL line on one side and to a network card installed in your PC on the other side

  5. Examples of Network Services • Most function at top three layers of the OSI model – application, presentation, and session layers • Must be a program running on both nodes of the network for the service to work

  6. Upper-level Protocols • Hypertext Transfer Protocol (HTTP) • Used by the World Wide Web • File Transfer Protocol (FTP) • Used to transfer files • Simple Mail Transfer Protocol (SMTP) • Used to transfer e-mail

  7. Uniform Resource Locator (URL)

  8. World Wide Web Browsers • Provide interface between Web sites and PCs • Access a server by either its IP address or its domain name • Use HTTP to request and pass documents on the Web • Terminology • Hypertext • HTML

  9. File Transfer • File Transfer Protocol (FTP) • Used to transfer files between two computers using same or different OS • Can be initiated at a command prompt or using an ISP

  10. File Transfer from a Command Prompt

  11. File Transfer Using FTP Software

  12. File Transfer Using FTP Software

  13. Network Drive Map • One of most powerful and versatile methods of communicating over a network • Uses network file service (NFS) software to make one PC appear to have a new hard drive • Files and folders on host computer are available even to network-unaware DOS applications

  14. Preparing a Windows NT Host Computer for a Network Drive Map

  15. Preparing a Windows NT Host Computer for a Network Drive Map

  16. Preparing a Windows NT Host Computer for a Network Drive Map

  17. Mapping the Network Drive from a Remote to a Host Computer

  18. Mapping the Network Drive from a Remote to a Host Computer

  19. Mapping the Network Drive from a Remote to a Host Computer

  20. Linux Operating System • Well-suited to support web servers, FTP servers, and file servers • A UNIX-like operating system; can use more than one shell

  21. Linux System Administrator • Installs updates to the OS (patches) • Manages backup processes • Supports installation of software and hardware • Sets up user accounts • Resets passwords • Generally supports users • Has root privileges

  22. Linux Operating System

  23. continued

  24. UNIX Commands

  25. Managing Processes • To initiate a process to run in the background, enter the name of the process at the command prompt followed by “&” • Linux starts the process and responds with a number (the process identifying number, or PID) • To stop a process, use the kill command

  26. Windows Manager • Several applications have been written to provide a GUI shell for UNIX and Linux; these shells are called X Windows

  27. A Typical X Window Screen

  28. Major Components of a GNOME Windows

  29. Network Troubleshooting Guidelines • Windows 9x dial-up problems (modem problems) • Cannot make a connection • You can connect, but you get the message “Unable to resolve hostname…” • After connecting, you get the error message “Unable to establish a compatible set of network protocols” • Problems with TCP/IP • Problems with TCP/IP configuration or suspected network problems (packet Internet groper or PING)

  30. Chapter Summary • Fundamentals of the hardware and software that make up networks • How to support a PC that interfaces with the Internet
