The outcome can aid network administrators to control Intranet access and provide security. Review the following link to write up an appropriate capture filter. Four network instructions were used in the analysis of the IP traffic and the results displayed the IP and Media Access Control (MAC) address sources and destinations of the frames, Ethernet, IP addresses, User Datagram Protocol (UDP) and Hypertext Transfer Protocol (HTTP). The writing snort rules document is an especially helpful reference for writing the. The IP traffics were captured and analyzed using Wireshark Version 2.0.3. The LAN was deployed on windows 8 with a D-link 16-port switch, category 6 Ethernet cable and other LAN devices. Note that display filters and capture filters dont have the same syntax, o you cant use most display filter expressions as capture filters. It was implemented using five computer systems configured with static Internet Protocol (IP) addresses used in monitoring the IP traffic on the network by capturing and analyzing live packets from various sources and destinations in the network. tshark -i eth1 -f diameter And the output: tshark: Invalid capture filter: 'diameter' That string looks like a valid display filter however, it isnt a valid capture filter (syntax error). This paper was designed to provide Intranet traffic monitoring by sniffing the packets at the local Area Network (LAN) server end to provide security and control.
