This function starts the server and it is called by 'main'
It works for both ipv4 and ipv6 using two different approaches.
In principle, one could always use the getsockattr retrieving the
data structure for socket address.
host - host address (IPv4 or IPv6 address are allowed)
port - listening port
keyfile - the file where key s stored (fingerprint will be retrreved automatically)
level - logging level (default is INFO)
ipv6 - use ipv6 procedure to get the socket address (for IPv6)
