System Ping#

Description#

Ping executes the ping command on the target and streams back the results. Some targets may not stream any results until all results are in. If a packet count is not explicitly provided, 5 is used.

Usage#

gnoic [global-flags] system ping [local-flags]

Flags#

count#

The --count flag sets the number of packets.

A count of 0 defaults to a vendor specified value, typically 5. A count of -1 means continue until the RPC times out or is canceled.

destination#

The --destination flag sets the destination address to ping. required.

do-not-fragment#

The --do-not-fragment flag sets the do not fragment bit. (IPv4 destinations)

do-not-resolve#

The --do-not-resolve flag disables the resolution of the returned addresses.

interval#

The --interval flag sets the interval between requests, e.g 1s, 10ms

protocol#

The --protocol flag sets the layer 3 protocol used to ping, possible values: v4 or v6

size#

The --size flag sets the size of request packet. (excluding ICMP header).

If the size is 0, the vendor default size will be used (typically 56 bytes).

source#

The --source flag sets the source address to ping from.

wait#

The --wait flag sets the duration to wait for a response.

Examples#
