Use snoop to Monitor Network Traffic

1. Log in to the root account on a DHCP server or BOOTP relay agent on the same subnet as the client.

2. Use the snoop command to trace network traffic. For example:

   snoop -o /tmp/output udp port 67 or udp port 68

   or

   snoop -o /tmp/output udp port bootps or udp port bootpc

   plus the per-interface argument, if there is one.

3. Boot the client and watch the network messages on the server.

4. Type:

   snoop -i /tmp/output -x 0 -v

   to view the packet traces.
