Wireshark uses Winpcap to capture packets, so it can only capture the packets on the networks supported by Winpcap.It lets you capture and interactively browse the traffic running on a computer network.Fields can also be compared against values.7.7 Sniffing Tools Sniffing Tool: Wireshark Protocols and fields can be checked for existence in the filter box.

http.www_authenticate - WWW-Authenticate.

http.proxy_connect_port - Proxy connect port.http.proxy_connect_host - Proxu connect hostname.http.proxy_authorization - Proxy authorization.icmpv6.recursive_dns_serv - Recursive DNS Server.icmpv6.ra.router_lifetime - Router lifetime.icmpv6.ra.retrans_timer - Retrans timer.icmpv6.ra.reachable_time - Reachable time.icmpv6.ra.cur_hop_limit - Cur hop limit.ICMPv6 - Internet Control Message Protocol version 6

tcp.time_relative - Time since first frame in the TCP stream.

tcp.time_delta - Time sence previous frame in the TCP stream.

- Conflicting data in segment overlap.

- Time until the last segment of this PDU.

tcp.continuation_to - This is a contiuation to the PDU in frame.

ip.addr - Source or Destination Address.

These filters and its powerful filter engine helps remove the noise from a packet trace and only see the packets of interest.ĭisplay filters allow us to compare fields within a protocol against a specific value, compare fields against fields and check the existence os specific fields or protocols.īellow you can find a small list of the most common protocols and fields when filtering traffic with Wireshark. There over 242000 fields in 3000 protocols that let you drill down to the exact traffic you want to see. Wireshark’s most powerful feature is it vast array of filters.
