     NAME    [Toc]    [Back]
	  atping - ping	an AppleTalk node

     SYNOPSIS    [Toc]    [Back]
	  atping [-l len] [-x] [-b] [-c] net.node
	  atping -O name [-T type ] [-Z	zone ] [-x] [-b] [-c] [-t] [-l

     DESCRIPTION    [Toc]    [Back]
	  The atping command attempts to use the Apple Echo Protocol
	  (AEP)	to ping	an AppleTalk node.  It is similar in function
	  to ping(1m).	In its usual usage, atping is given an
	  AppleTalk net	and node number, and it	sends an echo request
	  every	second.	It waits for response packets, and lists each
	  one as it is received.    The	output includes	a round	trip
	  time,	and a count of packets received	and lost. The net and
	  node arguments can be	prepended with a 0x to specify
	  hexadecimal input.

	  -x	       causes atping to	print its output in
		       hexadecimal.

	  -b	       (blast) flag causes atping to send packets as
		       quickly as possible to test the load-handling
		       of another machine.  A count of the number of
		       packets sent and	received is kept.  The high
		       packet volume produced may crash	some routers.

	  -c	       (compare) flag causes atping to compare the
		       return packets to ensure	the packets are	not
		       getting corrupted in transit.  Can be used in
		       conjunction with	-b

	  -l	       flag makes the echo packets len bytes long.
		       The default is 586, which is also the maximum.

	  -t	       makes atping wait at most 1 second for a
		       response, and exit with a code indicating
		       success (0) or failure (errno).	This is	good
		       for detecting in	a script if a machine has
		       failed.

	  -O, -T, and -Z
		       options cause atping to use NBP to look up the
		       address of the entity.  If the entity you wish
		       to ping is running K-Talk, you can simply
		       specify the machine's name, with	the -O option.
		       If the entity you wish to ping is another
		       device (such as a printer), you can specify the
		       type with -T (which defaults to "Echoer") and
		       the zone	with -Z	(which defaults	to "*",	the
		       local zone).  atping is usually used to check
		       network connectivity.  If there is no route

		       available to the	specified net, atping will
		       return "network is unreachable".

     CAVEATS    [Toc]    [Back]
	  When routers with multiple interfaces	configured for
	  AppleTalk are	pinged,	they may return	a ``from'' address
	  from an interface other than the one addressed.  This	is
	  normal.
