Day 5 Agenda
Previous homework: Read class notes, p. 15-17 on configuring Win98 network settings. Review Lab Exercise 6 in the WINLAB.DOC handout (p. 10) and read networking chapters online at http://www.informit.com.
Read troubleshooting guides section of class notes (p. 18-21),
review post-installation tips, p. 22-26 and Exercise 7 in labs section(p.11)
study for final quiz
Configuration: Necessary W98 network components:
Access Control Tab -- determines how server resources are shared on a Windows network
Share level provides two password options: read-only and full-access
User level stores individual account information on a Windows NT or Novell Netware server
===> About TCP/IP
IP Addresses, gateways, DHCP, and DNS Identification
(see also the Windows 98 Resource Kit, Network Adapters and Protocols->TCP/IP section)
Each computer on the network that connects through TCP/IP has a unique 12-digit address of the form xxx.xxx.xxx.xxx. A subnet is created by freezing the numerical values in the first, first two, or first three triplets for each computer. The variability of the numerical values in a subnet is determined by the subnet mask value entered in the TCP/IP properties.
TCP/IP Subnet Examples:
Class C subnet (one variable triplet, mask value of 255.255.255.0):
192.168.1.1, 192.168.2, 192.168.3 ........ 192.168.1.254
Class B subnet (two variable triples, mask value of 255.255.0.0):
169.254.1.1, 169.254.1.2 .......169.254.2.1, 169.254.2.2 ......169.254.254.254
Class A subnet (three variable triplets, mask value of 255.0.0.0)
10.0.0.0, 10.0.0.1, ,,,10.1.0.1 ---254, ----> 10.254.254.254
By a universally agreed-upon convention, certain subnet ranges are not used for Internet connectivity. This permits administrators to use these IP ranges for local area network workstations that should remain invisible to the Internet. The following subnet ranges are reserved for non-Internet use:
Class C: 192.168.1.x, Class B: 169.254.x.x
DHCP (Dynamic Host Configuration Protocol) is a Server OS feature that automatically recognizes new computers on the network and assigns a unique IP address (from a preconfigured range) to each computer as it appears.
DNS (Domain Name System) is a convention whereupon alphanumeric domain names (Yahoo.com, Firstworld.net, etc.) are assigned to unique IP addresses on the Internet so that any Internet computer can find them. These domain name-to-IP address tables are stored on specific computers (usually maintained by Internet Service Providers) called Domain Name Servers.
