ping
====
_________________________________________________________________
ping <host> [<length> [<interval> [<incflag>]]]
_________________________________________________________________
Ping (send ICMP Echo Request packets to) the specified <host>.
By default the data field contains only a small timestamp to aid
in determining round trip time; if the optional <length> argument
is given, the appropriate number of data bytes (consisting of hex
55) are added to the ping packets.
If the <interval> parameter is supplied, pings will be repeated
indefinitely at the specified interval.
*** N.B. Some versions of NOS expect the interval in seconds.
*** Others expect the interval in milliseconds!
If no interval value is supplied, a single, "one-shot" ping is
done. Responses to one-shot pings appear asynchronously on the
command screen, while repeated pings create a session that may be
suspended and resumed. Pinging continues until the session is
manually reset.
The <incflag> option causes a repeated ping to increment the
target IP address for each ping; it is an experimental feature
for searching blocks of IP addresses for active hosts.
The round-trip times reported by the 'ping' command depend on the
setting of the 'isat' mode. If 'isat' is on, times are reported
to the nearest millisecond. If 'isat' is off, times are reported
in multiples of 55mS.
