NAME

       aecho - send AppleTalk Echo Protocol packets to network hosts


SYNOPSIS

       aecho [ -c count ] ( address | nbpname )


DESCRIPTION

       aecho  repeatedly sends an Apple Echo Protocol (AEP) packet to the host
       specified by the given AppleTalk address or nbpname and reports whether
       a  reply was received. Requests are sent at the rate of one per second.

       address is parsed by atalk_aton(3).  nbpname is parsed by  nbp_name(3).
       The nbp type defaults to ‘Workstation’.

       When  aecho  is  terminated, it reports the number of packets sent, the
       number of responses received, and the percentage of  packets  lost.  If
       any  responses  were  received, the minimum, average, and maximum round
       trip times are reported.


EXAMPLE

       Check to see if a particular host is up and responding to AEP packets:
