Feedly:Darknet – The Darkside. fping 3 – Multi Target ICMP Ping Tool

from Darknet – The Darkside

a Show systems that are alive.

A Display targets by address rather than DNS name.

b n Number of bytes of ping data to send. The minimum size (normally 12) allows room for the data that fping needs to do its work (sequence number, timestamp). The reported received data size includes the IP header (normally 20 bytes) and ICMP header (8 bytes), so the minimum total size is 40 bytes. Default is 56, as in ping. Maximum is the theoretical maximum IP datagram size (64K), though most systems limit this to a smaller, system-dependent number.

B n In the default mode, fping sends several requests to a target before giving up, waiting longer for a reply on each successive request. This parameter is the value by which the wait time is multiplied on each successive request; it must be entered as a floating-point number (x.y). The default is 1.5.

c n Number of request packets to send to each target. In this mode, a line is displayed for each received response (this can suppressed withq orQ). Also, statistics about responses for each target are displayed when all requests have been sent (or when interrupted).

C n Similar toc, but the per-target statistics are displayed in a format designed for automated response-time statistics gathering.

shows the response time in milliseconds for each of the five requests, with the "−" indicating that no response was received to the fourth request.

d Use DNS to lookup address of return ping packet. This allows you to give fping a list of IP addresses as input and print hostnames in the output.

D Add Unix timestamps in front of output lines generated with in looping or counting modes (l,c, orC).

e Show elapsed (round-trip) time of packets.

f Read list of targets from a file. This option can only be used by the root user.

-g Generate a target list from a supplied IP netmask, or a starting and ending IP. Specify the netmask or start/end in the targets portion of the command line.

h Print usage message.

i n The minimum amount of time (in milliseconds) between sending a ping packet to any target (default is 25).

l Loop sending packets to each target indefinitely. Can be interrupted with Ctrl-C; statistics about responses for each target are then displayed.

m Send pings to each of a target hosts multiple interfaces.

n Same asd.

p <n> In looping or counting modes (l,c, orC), this parameter sets the time in milliseconds that fping waits between successive packets to an individual target. Default is 1000.

q Quiet. Dont show per-probe results, but only the final summary. Also dont show ICMP error messages.

Q n Likeq, but show summary results every n seconds.

r n Retry limit (default 3). This is the number of times an attempt at pinging a target will be made, not including the first try.

s Print cumulative statistics upon exit.

S addr Set source address.

I if Set the interface (requires SO_BINDTODEVICE support)

t n Initial target timeout in milliseconds (default 500). In the default mode, this is the amount of time that fping waits for a response to its first request. Successive timeouts are multiplied by the backoff factor.

T n Ignored (for compatibility with fping 2.4).

u Show targets that are unreachable.

O n Set the typ of service flag ( TOS ). n can be either decimal or hexadecimal (0xh) format.

v Print fping version information.

H n Set the IP TTL field (time to live hops).
