Wireshark GUI provides the filter Bar in order to apply a display filter. This bar is used to filter currently captures packets and network traffic according to the provided filters. This filter bar provides help with IntelliSense by listing available filters You can also filter results based on network ports. For example, to display only those packets that contain TCP protocol and have either source or destination port as 80, just write tcp.port eq 80 in the filter box. Here is an example snapshot : So you can see that all the packets containing TCP protocol and source/destination port as 80 were displayed in the output. 3. Filter results based on multiple condition This filter helps filtering packet that match exactly with multiple conditions. Suppose there is a requirement to filter only those packets that are HTTP packets and have source ip as ''. Use this filter: http&&ip.src== 8. Filter by Port Number.

Wireshark uses display filters for general packet filtering while viewing and for its ColoringRules. The basics and the syntax of the display filters are described in the User's Guide . The master list of display filter protocol fields can be found in the display filter reference While a capture filter can be useful to limit the traffic under investigation, when troubleshooting certain issues the capture filter can drop packets that may be essential, e.g. icmp, so at first don't set a capture filter. The capture filter syntax is detailed here, some examples can be found here and in general a port filter is port <port number> Many worms try to spread by contacting other hosts on ports 135, 445, or 1433. This filter is independent of the specific worm instead it looks for SYN packets originating from a local network on those specific ports.

Mit dem Mitschnittfilter ist es möglich zu bestimmen welcher Traffic durch Wireshark aufgezeichnet werden soll. Hierbei sind eine vielzahl von Einschränkungen möglich, die von verschiedenen Ports, Protokollen oder sogar bis zu bestimmten IP-Addressen reichen können. Die Syntax ist dabei der von tcpdump recht ähnlich. Zu beachten ist hierbei, dass Traffic der nicht den festgelegten Filter. This type of traffic uses TCP in the transport layer and operates on port 80. The filter used in this case is tcp.port==80. The filter used and the output is shown in The filter used in this case.

Wireshark and TShark share a powerful filter engine that helps remove the noise from a packet trace and lets you see only the packets that interest you. If a packet meets the requirements expressed in your filter, then it is displayed in the list of packets. Display filters let you compare the fields within a protocol against a specific value, compare fields against fields, and check the existence of specified fields or protocols The IP protocol doesn't define something like a port. Two protocols on top of IP have ports TCP and UDP. If you want to display only packets of a TCP connection sent from port 80 of one side and to port 80 of the other side you can use this display filter: tcp.srcport==80 && tcp.dstport==80 Similar you can define a filter for a UDP communication. You can narrow the filter with addtional conditions lik
