Labels:text | screenshot | font OCR: Help File ping <hostid> [<length> [<seconds> [<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 interval is specified, pings will be repeated indefinitely at the specified number of seconds; otherwise a single, "one shot" ping is done. Responses to one-shot pings appear asynchronous ly on the command screen, while repeated pings create a session that may be suspended and resumed. Pinging continues until the ses- sion 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.
