37 .Op Fl l Aq Ar log_file
42 provides an interface between the ATMARP server in the
43 kernel and the SCSP daemon for the Host ATM Research Platform
44 (HARP) networking software.
46 reads the ATMARP cache from the kernel periodically
47 and passes any updated entries to
50 propagated to remote servers.
51 It also accepts updated entries that remote servers have sent to
54 new or more up to date than current entries, installs them
55 in the kernel's ATMARP cache.
60 must be running before any ATMARP cache synchronization can take place.
64 starts, it parses its command line and puts
65 itself into the background.
