Installation and configuration
Colasoft Capsa can monitor and analyze the data transmitted in intranet and/or between intranet and extranet, or
over VLAN; however, only with correct installation and configuration can the program work properly. The following
sections introduce how to install and configure Colasoft Capsa in different network environments, including shared
network and switched network.
Installation Environment
Shared network and switched network are two common network environments today, before install Colasoft
Capsa, you should first know about the topology of your network.
Shared network
A shared network is also known as hubbed network which is connected with a hub.
Hubs are commonly used to connect segments of a LAN. When a packet arrives at one port, it is copied to the
other ports so that all segments of the LAN can see all packets. A passive hub serves simply as a conduit for the
data, enabling it to go from one device (or segment) to another. So-called intelligent hubs include additional
features that enable an administrator to monitor the traffic passing through the hub and to configure each port in
the hub. Intelligent hubs are also called manageable hubs. A third type of hub, called a switching hub, actually
reads the destination address of each packet and then forwards the packet to the correct port.
With a shared environment, Colasoft Capsa can be installed on any host in LAN. The entire network data
transmitted through the Hub will be captured, including the communication between any two hosts in LAN.
