There are some cases where this would fail like when the OS reallocates a port to a different app just before Wireshark queries the OS for PID for a port. With code changes, it should be possible for Wireshark to map port to PID. Refer to the wireshark-filter man page for more information about the slice operator and Wireshark display filters in general. Wireshark knows which port is being used and the OS knows the PID of the process that is using the port. For example, if the source address was 50.xxx.xxx.100 and the destination address was .152, then the packet would still match the filter, as the 1st byte of the source address would match as well as the last byte of the destination address. The primary benefit of the filters is to remove the noise (the traffic you are not interested in) and they help you narrow down the type of data you are looking for. It provides great filters with, which you can easily zoom in to where you think the problem may lie. Unfortunately, this doesn't work reliably because it will actually match either the 1st byte of either the source or destination addresses as well as the 4th byte of either the source or destination IP addresses. Wireshark is a powerful network analysis tool for network professionals. Note that you might be tempted to use a simpler filter such as: ip.addr=32
