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