NAME
atlook - look up AppleTalk devices accessible from UNIX

SYNTAX
atlook [ -dn ] [ -n ] [ -s ] [ -r <n> ] [ -t [p]<n> ] [ -l <n> ]
[ -P ] [ -S ] nbp-entity-name

DESCRIPTION
Atlook allows you to look for various nbp entities on the AppleTalk
internetwork. Atlook does a lookup on the wildcard nbp entity name
"=:=@*" (any object, any type, my zone) by default.

You can override the zone easily by simply specifying it. For
example, atlook myzone would do a lookup on "=:=@myzone". To
override the type or object, you should give a fully specified NBP
entity name, for example, atlook =:Macintosh*myzone. Normally, the
output is sorted with a primary key of "type" and a secondary key
of "object".

Atlook accepts the following arguments:

-P says to ping the entities after lookup. The timeout for
response is 5 seconds. The default length of the packet
is based on an internal structure whose size is system
dependent.

-S says to get the LaserWriter status after lookup.

-n says to sort by the network numbers for output.

-s says to sort the output by socket numbers.

-t [p]<n> can be used to specify the NBP timeout as <n> ticks (1/4
second units) on lookups. The default is 3 ticks. With
’p’ preceding the number, it specifies the ping timeout
in ticks. Using -t p<n> turns on pinging.

-r <n> can be used to specify the number of NBP retries (default
is 3).

-l <n> can be used to specify the ping packet length (lower
bound: internal data structure, upper bound: ddpMaxData
(currently 586). Using this option turns on pinging.

-d <cap debug flags>
can be used to specify standard CAP library debugging
flags. See cap(3)* for valid flags.

NOTES
Atlook figures out the round trip delay by inserting the time the
packet was sent into the echo request packet.

Tenon Intersystems is pleased to be able to provide selected
elements of the Columbia AppleTalk Package (CAP) with MachTen. The
CAP package is an excellent package enabling access to Apple
Macintosh peripherals from a Unix platform. The marriage of CAP
and MachTen provides an expanded forum for CAP in providing users
with greater access to their Macintosh hardware investment.
