Windows DDNS Update from Windows DHCP

Problem

You have a Windows DHCP server and a Windows DNS server. (You poor bastard.) Windows clients obtain a lease correctly and enter their names in the DNS zone correctly. Linux DHCP clients get a lease, but don't update their DNS names at all.

RedHat Family Solution

In /etc/sysconfig/network/ifcfg-eth? add the line:

DHCP_HOSTNAME=shortname
where shortname is the non-qualified name of your linux system.

Do a service network restart and you are done.

Fedora 27+

You probably need to mess around with the Network Manager:

# nmcli con modify "System ens192" ipv4.dhcp-hostname "wiki2"

It's also a good idea to set your system's hostname to the same thing.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
