I want you to start right away and capture pa ckets. My capture station is my Windows 2000 PC with an address of 192.168.1.11. You can use the Capture menu to start capturing packets, but I often prefer t he toolbar. In Figare 2-15, I cl icked the tri angle- shaped toolba r button that resembles the button on a CD player.

The icons on the ldft enable you to view diffident categories of inform^tioa loosely based on the OSI layem The Diagnosis tab) displays problems that Sniffep has deCermined to require your immediate attention, whereas the Symptoms tab specifies potential problems. The Objects tab identifies all the features apd network items that Sniffer identified over the entire capture process.

Figure 2-16 shows Sniffer capturing packets, but there is not much activity until you actually do something. ^tice the numbee of packets in the lkweh-rikht notner of the expert wiudow and how it increases as you produce traffic. A simple ping from hoste to hostb (192.168.L12) is enough to change ihat. Use the IP addm^ for the first: pin g to eMminate any name resolution for now. Ping again using the host name (hostb), and then stop the Sniffer capture using the toolbar or Capture men u. Example 2-37 shows my chmmand- promp- ping outpu t.
