ATSTAT(1) K-Talk by Xinet (29 Jul 1996 8.2) ATSTAT(1)
NAME
atstat - dump the AppleTalk tables and statistics
SYNOPSIS
atstat [ -x ] [ -m [ interval ] ] [unix]
DESCRIPTION
The atstat command prints out tables and statistics that it
reads from the AppleTalk kernel implementation. When
invoked, it will print a list of tables and let you select
one at a time for viewing. If invoked with the -m flag, it
will use curses to provide an interactive screen display
that is updated every interval seconds. Some of the
displays may require a large window or they will not fit.
The -x flag will cause all numbers to be printed in
hexadecimal.
There are options for viewing the AARP, DDP, and RTMP
statistics. These statistics are relatively self-
explanatory, and will very from implementation to
implementation. They can all be reset to zero by using the
"Clear statistics" option.
The AppleTalk Address Resolution Protocol (AARP) table
contains the Net, Node, and EtherNet address of all nodes
currently directly addressable. There will be a dummy entry
for each defended loopback node, specifying lo0 as the
interface. Only entries with the flag COM set are complete.
The timer field specifies the number of 50-second intervals
which have elapsed since the entry was utilized. Unused
entries are timed-out and flushed to keep the AARP table
from filling up.
The RTMP table contains an entry for each net that is
reachable from the machine. The router field contains the
net and node numbers of the router which advertises the
shortest distance to the net, and the dist field lists the
number of hops to that net. The Ethernet address is the
address of that router, and the interface is the host
interface which can communicate with that router.
The ATCB table is a list of the active AppleTalk Control
Blocks. There is an entry for each AppleTalk socket open on
the host. The address is the socket address on the local
host. If the local net and node number are both zero, this
socket will accept packets addressed to its socket from any
network attached to this host. These sockets are used by
the various daemons to maximize performance. The type
field is one of the known AppleTalk protocol types. The
AARP and RTMP fields indicate whether this socket has cached
AARP or RTMP entrys for the node it is communicating with.

DIAGNOSTICS
atstat: atopensock: error Typically this means that the
AppleTalk kernel (or module)
is not running.
atstat: SIOGETLOCS failed: error
Indicates a system resource
problem or mismatched versions
of atstat and AppleTalk
kernel.
atstat: could not open /dev/kmem
This means that the user
executing atstat did not have
sufficient permissions to read
/dev/kmem. atstat can be made
setgid kmem so all users can
run it.
