The netstat Command
Several options to the netstat command show various parts of the TCP/IP protocol parameters and counters. The most useful options are the basic netstat command, which monitors a single interface, and the netstat -i command, which summarizes all the interfaces. Figure 9-7 shows an output from the iostat -i command.
