This is a simple utility to listen for TaZmen Sniffer Protocol (TZSP) packets and output the contents on stdout in pcap format. It has only been lightly tested with Mikrotik RouterOS products, and may need alterations to work with other devices.

tzsp2pcap -f | wireshark -k -i -
tzsp2pcap -o "file.pcap" -C 1000000 # rotate file every 1MB (file.pcap.1, file.pcap.2, etc)
tzsp2pcap -o "file_%s.pcap" -G 10 # create new file every 10 seconds (file_UNIXTIMESTAMP.pcap)
tzsp2pcap -o "file.pcap" -C 1000000 -z gzip # rotate file every 1MB and gzip it (file.pcap.1.gz, file.pcap.2.gz, etc)
