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.
