Using RPCAP

Important: This chapter describes experimental functionality that might or might not work as expected depending on the specific implementation in third party software and hardware. No technical support will be provided for this functionality.

In addition to the remote capture functionality provided by CommView Remote Agent, CommView can also capture traffic from remote computers using the RPCAP (Remote Packet Capture) protocol. This protocol is supported by some hardware (e.g. Aerohive Access Points) and software (e.g. WinPcap).

To switch to remote monitoring mode, click File => Remote Monitoring Mode. An additional toolbar will appear in the CommView main window next to the main toolbar. Click the New RPCAP Connection button to open a new connection window.

To connect to a remote device, enter its hostname or IP address, specify the port number (RPCAP uses port 2002 by default), check the User Authentication box and specify a user name and password, if authentication is required, and then check the Promiscuous mode box if that is the capture mode you wish to use. Click Connect to establish a connection. Once the connection has been established, the Adapter drop-down list will be populated by available network interfaces. Click Capture to start capturing.
