The RPCAP (Remote Packet CAPture) system for Linux allows the capture of network traffic on a remote system. It is a two component system, with a "server" component running on the remote system, which uses libpcap to capture network packets, and uplink them to the client system. The client side component of rpcap is a library called librpcap, which exposes a subset of the libpcap API. The client and server components use standard Sun RPC communication mechanisms for providing a transparent, libpcap-compatible API for the capture of remote network traffic.
