![]() Wireshark uses the same syntax for capture filters as tcpdump, WinDump, Analyzer, and any other program that uses the libpcap/WinPcap library. Then the picture changes and you need to reassess the situation. An overview of the capture filter syntax can be found in the Users Guide.A complete reference can be found in the expression section of the pcap-filter(7) manual page. If you have confirmed you are tracing with the right interface and you have correctly typed your display filter, and you /still/ not seeing any packets, then the only thing to conclude is that those packets were never sent or received on your network interface. Then you should /only/ see packets with a source or destination port 8080. Once the trace has started, then you should be able to use type your filter (the /display/ filter) into the filter toolbar in the Wireshark interface. Then select that interface and click the Start button. I have this filter set up: But when I hit that server, I don't see anything show up in the capture log. ![]() To do this quickly and simply, I would click Capture > Interfaces and confirm which interface is receiving packets. How do I get Wireshark to filter for a specific web host Ask Question Asked 8 years, 8 months ago Modified 8 years, 7 months ago Viewed 30k times 4 I'm using Wireshark on OSX, but I can't make any sense out of the filtering system. tcp port 8080 is /capture/ filter, but tcp.port = 8080 is /display/ filter.įirst thing I would confirm is that I am using the right interface. Keep it short, its also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically. By using it, you can check everything that’s going on within your network, troubleshoot different problems. For the display filter, you'd use something like tcp.port > 21100 & tcp.port < 21299, and keep in mind here that port in this context refers to either the source port or the destination port. For example, if you want to capture traffic on your wireless network, click your wireless interface. Lee Stanton JWireshark represents the world’s most used protocol analyzer. Wireshark uses the libpcap filter language for capture filters. For the capture filter, you can use portrange 21100-21299, and you can refer to the pcap-filter man page for more information on capture filters. You have to decide whether to use a /capture/ filter or a /display/ filter - the syntax is different between those two filter types. XXX - Add a simple example capture file to the SampleCaptures page and link from here. Capturing Packets After downloading and installing Wireshark, you can launch it and double-click the name of a network interface under Capture to start capturing packets on that interface.
