NAME

6       atmarpd - ATMARP demon
7

SYNOPSIS

9       atmarpd [-b] [-d] [-D directory] [-l logfile] [-m] [-n]
10       atmarpd -V
11

DESCRIPTION

13       atmarpd  implements  the  ATMARP  protocol  as specified in RFC1577 and
14       RFC1755. Address resolution requests are sent from the kernel (using  a
15       comparably  simple  protocol)  to the ATMARP demon, which then performs
16       the dialog with the network.
17
18       atmarpd can operate as an ATMARP client and as an  ATMARP  server.   If
19       also supports the concurrent use of several IP over ATM interfaces.
20
21       atmarpd  is  configured from the command line using the atmarp program.
22       Unless debugging is enabled, the ATMARP table is  written  after  every
23       change  to  the file /var/run/atmarpd.table (or to a file with the same
24       name in a different directory, if the -D option is used).
25
26       Note that atmarpd disables support for SVCs if signaling is not  avail‐
27       able at start time, i.e. if atmsigd is not running.

OPTIONS

30       -b     Run  in  background  (i.e. in a forked child process) after ini‐
31              tializing.
32
33       -d     Enables (lots of) debugging output. By default, atmarpd is  com‐
34              parably quiet.
35
36       -D dump_dir
37              Changes   the   directory   where   atmarpd   writes  its  table
38              (atmarpd.table). By default, /var/run is used.
39
40       -l logfile
41              Write diagnostic messages to the specified file  instead  of  to
42              standard error. The special name syslog is used to send diagnos‐
43              tics to the system logger.
44
45       -m     Enables merging of incoming calls if the address is  known.   An
46              incoming  connection  on  which no InARP reply has been received
47              yet, but which originates from  an  ATM  address  for  which  an
48              ATMARP  entry  already  exists,  is  automatically added to that
49              entry. This assumes that there  is  a  1:1  mapping  between  IP
50              addresses  and  ATMARP addresses. By default, this assumption is
51              not made, which frequently results in  the  setup  of  duplicate
52              connections.  Note  that  RFC1577 requires that an ATMARP server
53              sends an InARP request on an incoming  connection.  Merging  may
54              therefore violate RFC1577 in this case.
55
56       -n     Prints addresses in numeric format only, i.e. no address to name
57              translation is attempted.
58
59       -V     Prints the version number of  atmarpd  on  standard  output  and
60              exits.
61

FILES

63       /var/run/atmarpd.table   ATMARP table
64       /proc/atm/arp            table of currently active IP over ATM VCs
65

BUGS

67       atmarpd  removes  ATMARP entries from the kernel table while refreshing
68       them.
