This is a followup to a previous post because that one stopped working, now - this works.

There’s not a lot of OC here, just clarity.

NameCheap DynDNS on a Pi3

I use NameCheap (because they’re anti-SOPA) for DNS. The client program, ddclient, can connect to NameCheap.

I’m using raspbian, so, first;

1. run sudo apt-get install ddclient on your Pi
2. find the dynamic DNS settings on NameCheap’s website
   • Dashboard >>> Domain List >>> Manage >>> Advanced DNS
   • they do like to change these things around
3. halfway down the page, there should be a DYNAMIC DNS thingie
   • enable it (if you haven’t already)
   • note the blurb-what-looks-like-a-SHA

4. edit your /etc/ddclient.confto look like this

       ################
       # namecheap ddclient.conf
       # from https://blog.dembowski.net/2013/namecheap-dynamic-dns-setup-with-ddclient/
       ################
       use=web, web=checkip.dyndns.com/, web-skip='IP Address'
       protocol=namecheap
       server=dynamicdns.park-your-domain.com
       login=your-domain-at-namecheap.whatnot
       password='blurb-what-looks-like-a-SHA'
       your-subdomain
   

After rebooting my Pi (and giving any DNS caches time to flush) I could phone-home!

… but you can also see if the DNS records on NameCheap’s website have updated.
