As an IP datagram contains both a source and a destination address, the expression will evaluate to true whenever at least one of the two addresses differs from 1.2.3.4. The reason for this, is that the expression ip.addr != 1.2.3.4 must be read as “the packet contains a field named ip.addr with a value different from 1.2.3.4”. In the Preferred DNS server box, type the IP address of the computer that resolves host names to IP addresses. Wireshark is a powerful network analysis tool for network professionals. Instead, that expression will even be true for packets where either source or destination IP address equals 1.2.3.4. Quite simply, it gives statistics on all the endpoints Wireshark has discovered. Filtering Broadcast and Multicast Packets. Unfortunately, this does not do the expected. Then they use ip.addr != 1.2.3.4 to see all packets not containing the IP address 1.2.3.4 in it. Often people use a filter string to display something like ip.addr = 1.2.3.4 which will display all packets containing the IP address 1.2.3.4. Using the != operator on combined expressions like eth.addr, ip.addr, tcp.port, and udp.port will probably not work as expected. So now that you have entered a network and. Which filters packets where either the source OR the destination is not C, and that's every packet, so it shows every packet. Wireshark is a network protocol analyzer that can be installed on Windows, Linux, and Mac. Also, include the timeframe of when you performed the operation requested by support. Which filters packets where source or destination match, and then hides them (correctly). Remember to mention the IP Address of the servers involved so Atlassian Support can use that to filter through the TCP dump. In Boolean Logic, A not equals B and not A equals B are the same test.īut, the relevant part of the WireShark documentation linked by Jürgen Thelen explains that in WireShark, ip.addr covers both the source and destination field, so the test is more like: not ((A or B) equals C)
