Labs: Students will complete the following labs during this class:

Lab 1: Conduct an FTP and Telnet session on the Internet.

Lab 2: Send a mail message over the Internet.

Lab 3: Capture packets and examine the process of Address Resolution on a single segment and across a router.

Lab 4: Plan out an IP addressing scheme for a fictitious company and implement it in the classroom network. This will include routers, bridges, hubs and workstations.

Lab 5: Implement IP addressing on a variety of different hosts in the classroom. These will include UNIX, NT and netware at a minimum.

Lab 6: Set up and implement BOOTP and DHCP servers.

Lab 7: Capture packets and examine the process associated with BOOTP and DHCP.

Lab 8: Implement IP addressing in a routed environment. Reconfiguration of the classroom environment to support routing, including changing addresses, netmasks, and physical reconfiguration of the network environment.

Lab 9: Capture and examine RIP traffic and ICMP traffic associated with the routed environment.

Lab 10: Configure a Default Router.

Lab 11: Install and configure a network management console to monitor the IP devices in the classroom.

Lab 12: Capture and examine SNMP traffic across different segments of the classroom network.

Lab 13: Demonstrate the vulnerability of the etc/password, etc/shadow, and etc/group files on a UNIX host to penetration.

Lab 14: Troubleshoot a variety of common problems with tools and techniques learned during the course of the class. Exercises will include examining the problems associated with duplicate IP addresses and incorrect subnet masks.
