Forcing single server for domain

It is possible to enforce Tigase mDNS component to check if there is no other host providing services for chosen domain name. By setting property singleServer to true. If this feature is enabled, then mDNS component checks if chosen domain is already in use (broadcasted in multicast DNS) and if so it stops startup of the server. This feature make it possible to start up Tigase and broadcast XMPP server mDNS information if already existing mDNS information resolves to the IP address of the host on which you are starting Tigase XMPP Server.

Example enabling single server mode. 

mdns () {
    singleServer = true
