The key to successful network
monitoring is the visibility of network traffic. If you need to
monitor only one computer on the network, there is no network
visibility question: You can simply install and run NetResident on
that computer. However, if you need to monitor multiple computers
on a LAN, it is important that you understand how to achieve
network visibility (i.e., the ability to “see” network traffic of
other stations from a single observation point).
In brief, to monitor other
computers on your LAN, you need to install NetResident on a gateway
computer or use a switch with the “port mirroring” feature. There
are many possible network layouts, so if you are new to network
monitoring, we recommend that you read the detailed, illustrated
white paper by TamoSoft, Promiscuous Monitoring in Ethernet
and Wi-Fi Networks (a PDF version is also
available.)
