Use tcpdump if you want a pcap to open up in wireshark later. Else, use tshark if you want a "text only" view of the SIP traffic without all the headers and extra information. Examples: Real-time traffic dump (full packets): tcpdump -nq -s 0 -A -vvv -i eth0 port 5060. I was recently looking at analysing packet data captured as a .pcap file and to filter information to standardWell as I am reading a capture file I will need to specify the -r argument to the filename and thentshark.exe r <.pcap> -e frame.number e frame.time e ip.src e ip.dst e tcp.srcport e sudo tshark -r mycaptures.pcap. 3. reads the le containing the packet captures.sudo tshark -f "multicast or broadcast" -w workers.pcap. could be used to fetch both types of packets from the network and have them stored in a le for subse-quence analysis.
