aecho

AECHO(1)							   Netatalk 2.2 							  AECHO(1)

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:

	   example% aecho bloodsport
	   11 bytes from 8195.13: aep_seq=0. time=10. ms
	   11 bytes from 8195.13: aep_seq=1. time=10. ms
	   11 bytes from 8195.13: aep_seq=2. time=10. ms
	   11 bytes from 8195.13: aep_seq=3. time=10. ms
	   11 bytes from 8195.13: aep_seq=4. time=10. ms
	   11 bytes from 8195.13: aep_seq=5. time=9. ms
	   ^C
	   ----8195.13 AEP Statistics----
	   6 packets sent, 6 packets received, 0% packet loss
	   round-trip (ms)  min/avg/max = 9/9/10

OPTIONS

       -c count
	   Stop after count packets.
