I want to use Tshark as a subprocess and I need to define a flow to display its packets, but I don't know the cmd to define a flow in tshark, just I know it in wireshark:
ip.src == ipAddr and ip.dst == ipAddrDst and udp.srcport == 33191 and udp.dstport == 2003 ;
So can you help me to find the equivalent cmd in tshark?
