SYNOPSIS

atmarpd [-d] [-l<log_file>] <net_intf> ...

DESCRIPTION

The atmarpd utility provides an interface between the ATMARP server in the kernel and the SCSP daemon for the Host ATM Research Platform (HARP) networking software. The atmarpd utility reads the ATMARP cache from the kernel periodically and passes any updated entries to scspd(8) so they will be propagated to remote servers. It also accepts updated entries that remote servers have sent to scspd(8) and, if they are new or more up to date than current entries, installs them in the kernel’s ATMARP cache. Both atmarpd and scspd(8) must be running before any ATMARP cache synchronization can take place.

When atmarpd starts, it parses its command line and puts itself into the background.

The command-line options are:

-l <log_file> Specify that atmarpd is to write log messages to the file named <log_file> rather than to the system log.
-d Specify that atmarpd is to be run in debug mode. In debug mode, atmarpd is not put into the background. Log messages are written to standard output instead of to the log file.
<net_intf> Specify the network interface(s) for which the host is providing ATMARP service and whose caches are to be synchronized using SCSP. If multiple network interface names are specified, atmarpd will provide an interface to scspd(8) for the servers on all the specified interfaces.

SIGNAL PROCESSING

The following signals can be used to control atmarpd:
SIGINT
Dump debugging information to a file. When it receives a SIGINT signal, atmarpd dumps a summary of its control blocks to a text file (see FILES).

FILES


.Sm off /tmp/atmarpd. <pid> . <seq> .out
.Sm on
Debugging information dump file name. The atmarpd utility writes a summary of its control blocks to this file when it receives a SIGINT signal. <pid> is the process ID of the daemon and <seq> is a sequence number which is incremented every time a dump is taken.
