pmap_set(8) -- Linux man page
NAMEpmap_set - set the list of registered RPC programs
DESCRIPTIONThe pmap_set command can be used to restart a running portmapper or to set the list of registered RPC programs on the local host. If you want to use the program to restart the portmapper you have to redirect the output of pmap_dump to a file. After this you can restart the portmapper and restore the list of the registered RPC programs by feeding the output of pmap_dump to the pmap_set command.
