![]() If Wireshark isn’t capturing packets, this icon will be gray. Square: If this is red, clicking it will stop a running packet capture.Shark fin: If this is blue, clicking it will start a packet capture. If Wireshark is capturing packets, this icon will be gray.This primitive helps us to apply filters on the specified protocol at either the Ethernet layer or the IP layer. This primitive helps us to apply a filter on packets whose length is less than or equal to the specified length, or greater than or equal to the specified length, respectively. But one thing is that tcp|udp must appear before src|dst. But if we want the source port or the destination port and TCP or UDP packets, then we must specify the keywords’ src|dst and tcp|udp before the primitive. This primitive helps us to apply filters on TCP and UDP port numbers. ![]() If our network number is different, then we can manually select the netmask or the CIDR prefix for the network. But if we want the source network or the destination network, then we must specify src|dst before the primitive. This primitive helps us to apply filters on network numbers. This primitive helps us to apply filters on packets that used the host as a gateway. But if we require the source address or destination address, then we must specify src|dst between the keywords ether and host. This primitive helps us to apply filters on Ethernet host addresses.
