.TH aecho 1 "17 Dec 1991" 2.0.0 Netatalk .SH NAME aecho \- send AppleTalk Echo Protocol packets to network hosts .SH SYNOPSIS aecho [ \fB\-c\fR\fI count\fR ] ( address | nbpname ) .SH 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. .PP address is parsed by \fBatalk_aton\fR(3). nbpname is parsed by \fBnbp_name\fR(3). The nbp type defaults to `\fIWorkstation\fR'. .PP 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. .SH EXAMPLE Check to see if a particular host is up and responding to AEP packets: .PP .nf example% \fBaecho 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 \fR.fi .SH OPTIONS .TP \fB\-c\fR\fI count\fR Stop after \fIcount\fR packets. .SH "SEE ALSO" \fBping\fR(1), \fBatalk_aton\fR(3), \fBnbp_name\fR(3), \fBaep\fR(4), \fBatalkd\fR(8).
