38 .Op Fl l Aq Ar log_file
44 utility provides an interface between the ATMARP server in the
45 kernel and the SCSP daemon for the Host ATM Research Platform
46 (HARP) networking software.
49 utility reads the ATMARP cache from the kernel periodically
50 and passes any updated entries to
53 propagated to remote servers.
54 It also accepts updated entries that remote servers have sent to
57 new or more up to date than current entries, installs them
58 in the kernel's ATMARP cache.
63 must be running before any ATMARP cache synchronization can take place.
67 starts, it parses its command line and puts
68 itself into the background.
70 The command-line options are:
