As long as the above is all on a combined frontend/backend host,
which I believe you mentioned in a later post, looks good. Also
looks like mine, except that the IP addresses are different.

Be sure to check all copies of config.xml, e.g.:

     grep "<Host>" {~mythtv,~}/.mythtv/config.xml

Having localhost in the config.xml causes a socket connection
rather than using a TCP connection, which is good.

What do these (run on the backend) return:

     nmap -p6543 --reason -6 ::1
     nmap -p6543 --reason 127.0.0.1
     nmap -p6543 --reason 192.168.1.100

You want to see this:

    PORT     STATE SERVICE REASON
    6543/tcp open  mythtv  syn-ack
