aecho - send AppleTalk Echo Protocol packets to network hosts
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 per-
centage 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:
