Comparison Operator value == 192.168.1.1 logical operator Expressions and tcp port Keyboard Shortcuts - main display window Move to the next packet or detail item. Move to the previous packet or detail item. Move to the previous packet, even if the packet list isn’t focused. Move to the next packet of the conversation (TCP, UDP or IP). Move to the previous packet of the conversation (TCP, UDP or IP). Move to the next packet, even if the packet list isn’t focused. Protocols - Values Move to the next packet in the selection history. In the packet detail, opens the selected tree item. In the packet detail, opens the selected tree item and all of its subtrees. In the packet detail, opens all tree items. In the packet detail, closes all tree items. In the packet detail, jumps to the parent node. In the packet detail, toggles the selected tree item. ether, fddi, ip, arp, rarp, decnet, lat, sca, moprc, mopdl, tcp and udp Common Filtering commands Filter syntax ip.addr == 10.10.50.1 ip.dest == 10.10.50.1 ip.src == 10.10.50.1 ip.addr >= [email protected] and ip.addr <= 10.10.50.100 ip.addr == [email protected] and ip.addr == 10.10.50.100 !(ip.addr == 10.10.50.1) ip.addr == 10.10.50.1/24 tcp.port == 25 tcp.dstport == 23 ip.addr == 10.10.50.1 and Tcp.port == 25 Main toolbar items Description Uses the same packet capturing options as the previous session, or uses defaults if no options were set Stops currently active capture Restarts active capture session Opens “Capture Options” dialog box Opens "File open" dialog box to load a capture for viewing Save current capture file Close current capture file Reloads current capture file Find packet based on different criteria Jump back in the packet history Toolbar Icon ~ Mill le) UM iM 2 Pp p Usage Filter by URL Filter by time stamp Filter SYN flag Wireshark Beacon Filter Wireshark broadcast filter Wireshark multicast filter Host name filter MAC address filter RST flag filter Toolbar Item Go Forward Go to Packet...
