NAME

ping − packet echoing

SYNOPSIS

/etc/ping host_addr [ packet-size ] [ -n num_packets ]

DESCRIPTION

Ping sends an ICMP echo packet to host once per second.  Each packet that is echoed back is reported on the screen, including round-trip time.  Ping terminates when the SIGINT signal is received, typically as a result of pressing the BREAK key.  When ping terminates, it reports statistics concerning the number of packets sent and lost as well as a summary of the round-trip times. 
 

host_addr The host_addr argument can be a host name or an internet address.  All symbolic names specified for a host are looked up in the host name data base, /etc/hosts (see hosts(4)). If it is an internet address, it must be in a format acceptable to the inet_addr(3N) function.

packet_size By default (when packet-size is not specified), the size of transmitted packets is 64 bytes.  The minimum value allowed for packet-size is eight bytes and the maximum is 2048 bytes.  Also, if packet-size is less than 16 bytes, there is not enough room for timing information.  In this case the round-trip times will not be displayed. 

−n num_packets
The number of packets ping will transmit before terminating.  Range: 1 to (2**31 -1), decimal.  Default: Ping will send packets until interrupted.
