  1. Chapter 11 Network Maintenance Ruth Watson Operating Systems Concepts 1/e Ruth Watson Chapter 11

  2. Objectives (1 of 2) • Explain the importance of a Disaster Recovery Plan • Describe a backup rotation scheme • Demonstrate how to boot a computer into safe mode • Explain the role of services • Explain the role of service packs Operating Systems Concepts 1/e Ruth Watson Chapter 11

  3. Objectives (2 of 2) • Explain the difference between a static and a dynamic IP address • Explain what the DHCP service does • Demonstrate how to use TCP/IP troubleshooting tools • PING and TRACERT • Explain what the DNS service does Operating Systems Concepts 1/e Ruth Watson Chapter 11

  4. Introduction • Maintaining the network is the primary role of a Network Administrator • Troubleshooting and monitoring resources is key Operating Systems Concepts 1/e Ruth Watson Chapter 11

  5. APIPA DoS attack DHCP IANA IPCONFIG NETSTAT PING TCP/IP TRACERT Important Terms to Understand Operating Systems Concepts 1/e Ruth Watson Chapter 11

  6. Tricks of the Trade - Server Backups • Disaster Recover Plan • Outlines a procedure in the event of a network failure • Weekly Backups • Daily incremental backups Operating Systems Concepts 1/e Ruth Watson Chapter 11

  7. Tricks of the Trade - Services Manual Automatic Operating Systems Concepts 1/e Ruth Watson Chapter 11

  8. Tricks of the Trade - Service Packs Operating Systems Concepts 1/e Ruth Watson Chapter 11

  9. Tricks of the Trade - Miscellaneous • Monitor processes • Use the task Manager • Install Anti-Virus • Update Anti-Virus • Install Utilities Operating Systems Concepts 1/e Ruth Watson Chapter 11

  10. Configuring and Testing IP Addresses • Computers must be configured to access the Internet • A unique IP address must be assigned to every device on the Internet • A Network Administrator must configure computers to use the IP addresses Operating Systems Concepts 1/e Ruth Watson Chapter 11

  11. Static IP Addresses • Assigning IP addresses statically is the hard way • Network Administrators must key in: • The IP Address • The Subnet Mask • The default Gateway • The DNS Operating Systems Concepts 1/e Ruth Watson Chapter 11

  12. Dynamic IP Addresses • Letting the operating system automatically configure IP addresses is much easier • The dynamic host configuration protocol (DHCP) service allows you to enter a range of IP addresses to obtain Operating Systems Concepts 1/e Ruth Watson Chapter 11

  13. Troubleshoot IP Problems - IPCONFIG • IPCONFIG: • Type at command prompt or at Run to determine your IP address Operating Systems Concepts 1/e Ruth Watson Chapter 11

  14. Troubleshoot IP Problems - APIPA • APIPA: • Automatic private IP addressing • Enables clients to communicate on a LAN without Internet access Operating Systems Concepts 1/e Ruth Watson Chapter 11

  15. Troubleshoot IP Problems - Ping • Ping • If you cannot access the Internet, try a Ping • When you Ping, you send something like an echo to the address • The echo travels there and back • If you do not get a reply, something is wrong with the NIC card or TCP/IUP stack Operating Systems Concepts 1/e Ruth Watson Chapter 11

  16. DNS Problems - TRACERT • TRACERT • Trace Route Utility • Bounces and echo to the destination • Shows every router along the way Operating Systems Concepts 1/e Ruth Watson Chapter 11

  17. DNS Problems - Hostname • HOSTNAME • Gives you information about yourself • Tells you the host name of the computer you are running Operating Systems Concepts 1/e Ruth Watson Chapter 11

  18. DNS Problems - NETSTAT • NETSTAT • Lets you know what communication ports on your computer are in use and who is using them • Communication ports range from 0 – to 1024 • Ports 135 and 139 are used by Windows Operating Systems Concepts 1/e Ruth Watson Chapter 11

  19. Summary • Maintaining a network takes a lot of work and time. • Maintenance includes: • Backup schedules • Repairs • Services • Downloading • Installing • Troubleshooting • Try to troubleshoot connections problems via: • PING and TRACERT • Check current IP address via: • IPCONFIG Operating Systems Concepts 1/e Ruth Watson Chapter 11
