yarpserver [OPTIONS] --config filename.conf Load options from a file. --portdb ports.db Store port information in named database. Must not be on an NFS file system. Set to :memory: to store in memory (faster). --subdb subs.db Store subscription information in named database. Must not be on an NFS file system. Set to :memory: to store in memory (faster). --ip IP.AD.DR.ESS Set IP address of server. --socket NNNNN Set port number of server. --web dir Serve web resources from given directory. --no-web-cache Reload pages from file for each request. --ros Delegate pub/sub to ROS name server.
This starts a name server running on the current machine, optionally specifying the socket-port to listen to (default whatever was used in the previous invocation, as recorded in a configuration file, or 10000 if this is the first time to run). Also, the IP by which the name server should be identified can optionally be specified (default is a fairly random choice of the IPs associated with the current machine).
If possible, a fallback multi-cast server will be started with IP 188.8.131.52 and port number 10001. The purpose of this server is to allow yarp processes to find the yarp name server in the absence of correct configuration.
