ping(1M) ping(1M)

option.

packet-size The size of the transmitted packet, in bytes. By default (when packet-size is not

speciﬁed), the size of transmitted packets is 64 bytes. The minimum value allowed for

packet-size is 8 bytes, and the maximum is 4095 bytes. If packet-size is smaller than 16

bytes, there is not enough room for timing information. In that case, the round-trip

times are not displayed.

count The number of packets ping will transmit before terminating. Range: zero to

2147483647. The default is zero, in which case ping sends packets until interrupted.

When using ping for fault isolation, ﬁrst specify a local address for host to verify that the local network

interface is working correctly. Then specify host and gateway addresses further and further away to deter-

mine the point of failure. ping sends one datagram per second, and it normally writes one line of output

for every ICMP Echo Response that is received. No output is produced if there are no responses. If an

optional count is given, only the speciﬁed number of requests is sent. Round-trip times and packet loss

statistics are computed. When all responses have been received or the command times out (if the count

option is speciﬁed), or if the command is terminated with a SIGINT, a brief summary is displayed.

This command is intended for use in testing, managing and measuring network performance. It should be

used primarily to isolate network failures. Because of the load it could impose on the network, it is con-

sidered discourteous to use ping unnecessarily during normal operations or from automated scripts.
