That's really embarrassing. Because I thought I'd waited for long enough. 
But I just logged in (I forgot I now have a static IP to my house and can 
log in remotely) and waited ~3 minutes and up popped the login prompt.

After some clunking about I added the interface to /etc/hosts and fixed 
the /etc/resolv.conf and, lo, it works.

The /etc/hosts didn't appear to make a difference to anything, which is 
odd since if DNS resolution was broken all of the interfaces should've 
been slow.

So I still have a mystery, but it works, so, thanks for pointing out what 
should've been obvious Mouse, genuinely appreciated.
