CS 302, Spring 2005 Assignment #4: 15 Points. Due Date: Tuesday, 4/12/05. Study Chapter 5 of Frisch. (5) 1. Update the VMware identification of your virtual RHEL3 machine to provide a unique network interface address as described in the lab announcement and discussed in class. Reboot your virtual machine and report the network settings obtained using DHCP for: (a) hardware (MAC) address, (b) hostname (including domain), (c) host IP address, (d) nameserver IP address, and (e) gateway/router IP address. Show the commands used to obtain each network setting.** (2) 2. Use the 'nslookup' utility to obtain the names of the domain nameserver and gateway from the IP addresses in problem #1 above.** (2) 3. Use the 'ping' program to broadcast ICMP packets to all hosts connected on your subnet. Use the 'arp -a' command to display the names, IP and MAC addresses of the hosts which responded to the ping broadcast. Check for any duplicate MAC or IP addresses. What problems are duplicate addresses likely to cause?** (1) 4. Use 'netstat' to view the TCP connections on your virtual host and identify as many as you can.** (2) 5. Use 'traceroute' to trace the network connection to www.ia.lab. What is the IP address of the lab webserver? Use 'telnet' to connect to the webserver with: 'telnet www.ia.lab 80'. Enter a GET command and show the http output from the server.** (1) 6. Configure the ntpd service and provide boot/syslog output which demonstrates it is working.** (2) 7. Configure the telnet service on your virtual machine. Verify that you can use telnet to connect to your virtual machine from your Windows host (run 'telnet' from Start->Run Command menu). Are you able to login to your virtual host using telnet? Explain.** **Output from Linux commands and programs should be saved to a file exactly as it is produced using either I/O redirection (>) or the 'script' command, printed and handed in along with your answers to the questions. Source code must be fully commented, including your name and the problem number.
