netmate 0.2.0-9 (arm64 binary) in ubuntu disco

 netmate was inspired in netdude[1] (dead) and can be used to learn and teach
 about TCP/IP protocols. It is a GTK+ program that shows lines selected from
 files in pcap style (generated by tcpdump and Wireshark or another code based
 in libpcap) as 32-bit headers, identical to the used by RFCs.
 .
 This program works with Ethernet, IPv4, IPv6, TCP, UDP, ICMP, ICMP6, NDP and
 others.
