Tcpdump -nq -s 0 -i eth0 -G3600 -w /tmp/trace/sip-%F-%H-%M-%S.pcap port 5060ĭaemonize and log 2 ports, rotate log every hour. Save a new time-stamped file approximately once per hour on the specified port Tcpdump -nq -s 0 -i eth0 -w /tmp/dump.pcap port 5060 Tcpdump -nq -s 0 -A -vvv -i eth0 port 5060 Real-time traffic dump (full packets) to stdout: Else, use tshark if you want a "text only" view of the SIP traffic without all the headers and extra information. Use tcpdump if you want a pcap to open up in Wireshark later. 13.5.1 Windows workstation to remote linux server.13.5 Remote live capture with local wireshark.1.1.3 Using Wireshark to Analyze pcap Files.1.1.2 Capturing Calls For a Specific User.A packet capture might be required by developers to help troubleshoot your installation. Here we can see tcpdump caught a variety of packages, the use of “Telephony” under the “VoIP Calls”, the system will automatically summarize during the call.Ħ、Select a call, click the Flow button, wireshark will use a graphic to represent the call, click the appropriate steps, we can see the corresponding IP packet information.Capturing SIP and RTP packets can reveal trouble with the configuration of FreeSWITCH or the endpoints connecting to it. Tcpdump will output some capturing packet information, so tcpdump’s mission is complete, download the pcap file and turn the wireshark.ĥ、Wireshark can download from ，install and run wireshark, then open the internal.pcap file. Indicates that packets received by any network interface are saved to the internal.pcap file.Ĥ、After the implementation of the system will stop here, this time we can make a phone call, and then use “Ctrl+c” to end.
Tips: In some cases, the system environment is more complicated, we hope to get the complete call information, then we can use tcpdump access to network data, the use of wireshark for further analysis.ġ、If don’t have tcpdump, please do as follows:Ģ、The capture command is executed and the captured information is saved in a file.
