• Discuss IPv6 and the future of IP
• Configure a TCP/IP network
• Understand the difference between hubs, routers and switches
• Install and Configure SAMBA
• Setup a Nameserver using BIND
• Use basic Linux networking commands
• Understand routing and routing protocols
• Understand the 802 protocols and their relationship to networking
• Configure an NFS server

Topic Outline

Overview of TCP/IP - 10%

• Network drivers and loadable kernel modules

Basic TCP/IP Networking - 20%

• Using ifconfig, route, netstat, ping, traceroute, nslookup, dig, and ip to troubleshoot networks
• Using a network protocol analyzer (wireshark) to diagnose problems
• Using a port scanner (nmap) to find open ports on your machine
