[44net] Trying to get set back up

https://www.qsl.net/kb9mwr/wapr/tcpip/ampr-ripd.html

Is this site still valid?

Specifically this?  In the 'new way of things'  will I still see traffic from amprgw.ucsd.edu?

tcpdump -i enp3s0 -vvv host amprgw.ucsd.edu or ip proto \icmp

Because I'm not seeing anything here from amprgw. Though I'm just monkeying with it the first time now, so could just be 'new user stupid'

ifconfig tunl0 up 44.4.28.50 netmask 255.255.255.255 ip rule add to 44.4.28.50 table main priority 44 ip rule add dev tunl0 table 44 priority 45 ip rule add dev enp3s0 table 44 priority 46 ip rule add from 44.4.28.50 table 44 priority 47
