Here are some artciles for another tools: Nice tutorial available at Other SIP analysis tools Home page of the tcpdump tool is located here:

tcpdump -nq -s 0 -i eth0 -w /tmp/dump.pcap port 5060

Or should be used with verbose extensions, which print some under layer protocol details, as check sums, header lengths… tcpdump -nqt -s 0 -A -vvv -i eth0 port 5060Ģ) Second option to use tcpdump is to capture data and write them to a pcacp file, then do post analysis, using wireshark for example. User-Agent: eyeBeam release 1102q stamp 51814 s capture number of bytes from a packet, 0 = default options which is max 65535, or simply a whole packet q be quite, print fewer output informations n do not convert IP address to DNS names

Its usage for SIP message analysis may look like:ġ) Display real-time to a console tcpdump -nqt -s 0 -A -i eth0 port 5060 TCPdump allows write sniff to a file or display it in real-time. TCPdump is preinstalled on many Linux distributions, or may be installed directly from the Debian repository: apt-get install tcpdump TCPdump is a powerful command-line packet analyzer, which may be used for a SIP message sniffing/analyzing, and thus for the troubleshooting of a SIP system.
