The server will be auto located if no server name is given. First it will look for the environment variable $ROAR_SERVER. If this variable is non existing libmuroar will do the auto location based on a list of possible server locations. This list contains the user's private socket address, the global UNIX socket address, an entry for localhost using TCP/IP, the local default DECnet object address as well as an entry for the abstract UNIX namespace (+abstract).
