NAME

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

SYNOPSIS

atlookup [-d] [-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. 

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

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

−s nn
Instructs atlookup to wait nn seconds between consecutive attempts to complete a lookup successfully.  The default is to space retries one second apart. 

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

−x Prints the 8-bit ASCII characters on output as hexadecimal numbers of the form XX (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 current zone name.  If you don’t specify a zone name, the current zone is the default. 

The object and type arguments can be the equal sign (=), which matches any string of characters. 

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 current 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 2 entries in zone My-Zone

6b19.a3.fd Light of Day:AFPServer

6b69.a3.fd Lucy:AFPServer
