- 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.
