Discover as many ethernet (MAC) addresses as you can on the university LAN. You get +1 point for each unique Ethernet address you report which is on the university LAN, up to a maximum of 10. You get -1 point applied to (i.e. DEDUCTED from) your maximum score of 10, for each unique Ethernet address you report which is NOT on the university LAN. On System2, you may use the /etc/arp command. For example:
system2.newhaven.edu> /etc/arp system1.newhaven.edu system1.newhaven.edu (204.60.72.3) at 0:a0:24:68:ed:a9Hint: To get started quickly, use the command /etc/arp -a to list the current contents of the Address Resolution Protocol (ARP) cache, which contains recently used addresses. In fact, the best way to cause an entry to appear in the cache, is to try to send a frame to it. To do this, you can use any network command such as /etc/ping, ftp or telnet. For example:
system2.newhaven.edu> /etc/arp p1 p1 (204.60.72.221) -- no entry system2.newhaven.edu> /etc/ping p1 p1.cs.newhaven.edu is alive system2.newhaven.edu> /etc/arp p1 p1 (204.60.72.221) at ....You can use an IP number instead of a Domain Name for any of the commands above. You can also use the nslookup command to discover IP numbers from Domain Names, and to discover names within a domain.
Email your 10 ethernet addresses (preferably sorted numerically) to jeffrey.denenberg@ieee.org by Tuesday, November 28.
