You can use the snoop utility to capture and inspect network packets to determine what kind of data is transferred between systems. You can use the snoop utility to see what happens when one system uses the ping command to communicate with another system. To view network traffic between two specific systems, perform the command:
# snoop sys41 sys42
sys41 -> sys42 ICMP Echo request
sys42 -> sys41 ICMP Echo reply
Use the -a option to enable audible clicks, which notify you of any network traffic. Although noisy, the clicks are useful when troubleshooting.
The following example shows how to turn on audible clicks for all network traffic related to a Dynamic Host Configuration Protocol (DHCP) boot:
# snoop -a dhcp
