Hi,

When compiling on stock Centos7 pcap will complain about unknown types u_int, u_short, u_char etc.

Adding "-D_GNU_SOURCE" to the CFLAGS in Makefile solves the issue and the app compiles clean.

Hi,

This good piece of code can be compiled for Windows (Cygwin), and also in other platforms with small changes in the Makefile:

# Configurable variables
CFLAGS = -g -D_GNU_SOURCE -Wall -Wextra -pedantic -O2

tzsp2pcap: tzsp2pcap.c
    cc -std=c99 -o $@ $(CFLAGS) $(LDFLAGS) $< -lwpcap

.PHONY: clean all

all: tzsp2pcap

clean:
    rm -f tzsp2pcap

(Note: use '-lwpcap' for linking with WPCAP.DLL; and '-lpcap' for any other platform).

I hope someone commits this change, and share a binary version for Windows. ;)

I'm no coder in C so bare with me.

                if (hdr->version == 1 &&
                    hdr->type == TZSP_TYPE_RECEIVED_TAG_LIST)
                {

is looking for a header type of TZSP_TYPE_RECEIVED_TAG_LIST(0). However, the TZSP my router stream is sending (using rsniffer), hdr->type is END(1). As such, it just prints "packet format not understood".

The rsniffer TZSP stream works perfectly in wireshark, so not sure if the issue is with tzsp2pcap, rsniffer or wireshark.

I've supplied a sample tzsp.pcap.
tzsp.zip

I already have recorded PCAP file and want select packets to UDP port 37008 and de-encapsulate from TZSP.
Could you add option ti specify PCAP file as input.
