wireshark capture filter all traffic netmask

This primitive allows you to filter on network numbers.

That is, where the Ethernet source or destination was host but neither the source nor destination IP address was host. This primitive allows you to filter on packets that used host as a gateway. If these are not present, packets where the specified address appears in either the source or destination address will be selected. You can optionally include the keyword src|dst between the keywords ether and host to specify that you are only interested in source or destination addresses. This primitive allows you to filter on Ethernet host addresses. If these are not present, packets where the specified address appears as either the source or the destination address will be selected. You can optionally preceed the primitive with the keyword src|dst to specify that you are only interested in source or destination addresses. This primitive allows you to filter on a host IP address or name. ]Ī primitive is simply one of the following: For a further reference, have a look at: Ī capture filter takes the form of a series of primitive expressions, connected by conjunctions (and/or) and optionally preceeded by not: The following is a short description of the capture filter language syntax. Note: This capture filter language is different from the one used for the Wireshark display filters!Įxample Ethernet: capture all traffic to and from the Ethernet address 08:00:08:15:ca:feĮxample IP: capture all traffic to and from the IP address 192.168.0.10Įxample TCP: capture all traffic to and from the TCP port 80 (http) of all machinesĮxamples combined: capture all traffic to and from 192.168.0.10 except httpīeware: if you capture TCP/IP traffic with the primitives 'host' or 'port', you will not see the ARP traffic belonging to it! This language is explained in the tcpdump man page under 'expression' ( and search for 'selects which'). Wireshark uses the pcap (libpcap/WinPcap) filter language for capture filters. This is done to reduce the size of the resulting capture (file) and is especially useful on high traffic networks or for long term capturing.

Capture Filters are used to filter out uninteresting packets already at capture time.
