NAME
atmarpd - ATMARP demon
SYNOPSIS
atmarpd [-b] [-d] [-D directory] [-l logfile] [-m] [-n]
atmarpd -V
DESCRIPTION
atmarpd implements the ATMARP protocol as specified in RFC1577 and
RFC1755. Address resolution requests are sent from the kernel (using a
comparably simple protocol) to the ATMARP demon, which then performs
the dialog with the network.
atmarpd can operate as an ATMARP client and as an ATMARP server. If
also supports the concurrent use of several IP over ATM interfaces.
atmarpd is configured from the command line using the atmarp program.
Unless debugging is enabled, the ATMARP table is written after every
change to the file /var/run/atmarpd.table (or to a file with the same
name in a different directory, if the -D option is used).
Note that atmarpd disables support for SVCs if signaling is not
available at start time, i.e. if atmsigd is not running.
OPTIONS
-b Run in background (i.e. in a forked child process) after
initializing.
-d Enables (lots of) debugging output. By default, atmarpd is
comparably quiet.
-D dump_dir
Changes the directory where atmarpd writes its table
(atmarpd.table). By default, /var/run is used.
-l logfile
Write diagnostic messages to the specified file instead of to
standard error. The special name syslog is used to send
diagnostics to the system logger.
-m Enables merging of incoming calls if the address is known. An
incoming connection on which no InARP reply has been received
yet, but which originates from an ATM address for which an
ATMARP entry already exists, is automatically added to that
entry. This assumes that there is a 1:1 mapping between IP
addresses and ATMARP addresses. By default, this assumption is
not made, which frequently results in the setup of duplicate
connections. Note that RFC1577 requires that an ATMARP server
sends an InARP request on an incoming connection. Merging may
therefore violate RFC1577 in this case.
-n Prints addresses in numeric format only, i.e. no address to name
translation is attempted.
-V Prints the version number of atmarpd on standard output and
exits.
FILES
/var/run/atmarpd.table ATMARP table
/proc/atm/arp table of currently active IP over ATM VCs
BUGS
atmarpd removes ATMARP entries from the kernel table while refreshing
them.
