atlookup(1)                                                        atlookup(1)




NAME

       atlookup  -  looks up network-visible entities (NVEs) registered on the
       AppleTalk network system



SYNOPSIS

       atlookup [-d] [-a] [-r nn] [-s ss] [-x] [object[:type[@zone]]]

       atlookup -z [-C]



ARGUMENTS

       -C      Prints zones in multiple columns.

       -d      Prints the network address in decimal numbers.

       -a      Don't display network addresses

       object  Specifies the name of the object to be looked up.

       -r nn   If the lookup is unsuccessful, the system tries again the  num-
               ber of times specified by nn.  The default is to try the lookup
               eight times.

       -s nn   Instructs atlookup to wait a certain  number  (ss)  of  seconds
               between consecutive attempts to complete a lookup successfully.
               The default is to space retries one second apart.

       type    Specifies the type of object to be looked up.

       -x      Prints the 8-bit ASCII characters on output as hexadecimal num-
               bers of the form      (where X is a hexadecimal digit).

       -z      Lists all zones in the network.

       zone    Specifies  the zone in which the lookup is to be performed. You
               can use an asterisk instead of a zone name to indicate the cur-
               rent  zone name.  If you don't specify a zone name, the current
               zone is the default.

               The object and type arguments can contain wildcard  characters.
               The  equal  sign (=) indicates a wildcard lookup.  For wildcard
               lookups to work correctly with all nodes,  the  only  character
               specified  in  the  string must be the wildcard character. How-
               ever, AppleTalk Phase 2 nodes  also  honor  a  single  embedded
               wildcard  character, `='. Under this scheme, one wildcard char-
               acter can appear anywhere in the string and can match  zero  or
               more  characters.  Note, however, that although an embedded `='
               is acceptable in object and type arguments  of  atlookup,  only
               the  nodes  implementing AppleTalk Phase 2 protocols respond to
               such a query.  For this reason, the resulting list of NVEs  may
               be incomplete.



DESCRIPTION

       atlookup  uses  the  Name  Binding  Protocol (NBP) to look up names and
       addresses of the specified NVEs.

       The default is to look up all the entities (of all types) in  the  cur-
       rent  zone.   Specifying  the object, type, or zone on the command line
       changes the scope of lookup.

       Information about the NVEs is displayed in a table format, one line per
       NVE.   Each  line gives the names of the object, type, and zone and the
       numbers of the network, node, and socket.



EXAMPLES

       This command looks up all NVEs registered in the local AppleTalk zone:

               atlookup

       In response, the system displays output similar to this:

               Found 5 entries in zone My-Zone
               6b5b.c3.ea 3-Eyed Monster:LaserWriter
               6b5b.80.fd 3-Eyed Monster Spooler:LaserWriter
               6b14.84.ea Incognito :LaserWriter
               6b19.a3.fd Light of Day:AFPServer
               6b51.27.fd Nets-R-Us Spooler:LaserWriter

       In an extended AppleTalk network, this command displays  all  NVEs  (of
       any type) in the current zone whose names start with L and end in y:

               atlookup L=y:=

       The output might be similar to this:

               Found 1 entries in zone My-Zone
               6b19.a3.fd Light of Day:AFPServer
