Advice to people implementing dynamic dns with easydns.com
Forget about using one of the (many) totally idiotic dyndns clients for Linux. The correct solution is to just call curl from a cron job.
See the description of the easydns.com "protocol". Where by "protocol" we mean a single HTTP GET request.
Note that if you use myip=22.214.171.124 (why not 0.0.0.0?) the server will figure out your IP automatically, which is basically always what you want. Having your (aforementioned idiotic) dyndns client try to guess it for you, when it's almost always behind a NAT router, is totally useless.
I hate computers.
ssh+2FA to all your machines, anywhere, without opening firewall ports.
