![]() I am using tshark version 2.2.6 on Debian 9. tshark -t ad -T fields -e ip.src -e -Y " eq 0"Īny pointers that can help in this regard. Though the command runs it just outputs without the timestamp. However I am not able to get both working together. Its quite limited, youd have to dissect the protocol by hand. See the pcap-filter man page for what you can do with capture filters. ![]() tshark -n -T fields -e -f src port 53 -Y contains 'foo'. ![]() One of the reasons is that some capture filters might work on some physical interfaces while they might not work on others. Its more easily done with a display (wireshark) filter than with a capture (pcap) filter. You cant actually activate a capture filter from there. For instance if i try something like tshark -t ad -n -T fields -e ip.src -e -f 'dst port 53' -Y " eq 0" 3 Answers: 1 When you select 'Capture -> Capture Filters' you will get a window in which you can define, alter and delete capture filters for future use. A little bit more detail of the same filter. Below is a brief overview of the libpcap filter language’s syntax. jackOfAll: if you want to filter by interface name you have to use pcapng, i.e. Wireshark capture filters are written in libpcap filter language. The third octet has to be either the number 32 or 33 and the final octet can be any 3 digit number between 0 and 9. Wireshark supports limiting the packet capture to packets that match a capture filter. The second octet should only consist of the number 1, 2 or 5. I am not able to get the time stamps along with the filters working. Our filter will look for a source IP address which starts with 142 in the first octet. Using the TShark we can create a Protocol based Hierarchy Statistics listing the number of packets and bytes using the io,phs option in the -z parameter. I am using this to filter all the DNS queries in my system. I am trying to use tshark with a few flags and also get timestamp for each filtered trace.
