Wireshark CSC8510 David Sivieri

what is wireshark? Open source packet analyzer Available for Windows, macOS, Linux, UNIX variants Can place network interface controller in promiscuous mode Promiscuous mode allows network controller to see network traffic not sent to that particular controller

Features Select from multiple network controllers Live packet capture or read pre-captured files (pcap files) Encapsulation of data is displayed to user. Different fields are parsed and displayed to user Different network protocol structure displayed to user. Multiple filters allowed.

FILTERS Filters can alter which packets the users sees based on filter criteria Common filters ip.dst_host ip.src_dst tcp, udp, icmp

OSI MODEL and packets
