When setting up fred-client the usual procedure for installing it works
as expected.
But when calling it it gives this error:
ERROR: getaddrinfo() socket.error [9] servname not supported for ai_socktype
The solution is to modify fred-client.conf so the socket type is forced,
as shown here
;; Force socket type. Valid value is: IPv4 or IPv6.
;; Default is to use server's socket type.
;socket = IPv6
socket = IPv4
