oping - send ICMP ECHO_REQUEST to network hosts
oping [-4 | -6] [-c count] [-i interval] host [host [host ...]]
oping uses ICMPv4 or ICMPv6 ECHO_REQUEST packets to measure a hosts reachability and the network latency. In contrast to the original ping(8) utility oping can send ICMP packets to multiple hosts in parallel and wait for all ECHO_RESPONSE packets to arrive. In contrast to the fping utility (URL is listed in SEE ALSO) oping can use both, IPv4 and IPv6 transparently and side by side.
Force the use of IPv4.
Force the use of IPv6
Send (and receive) count ICMP packets, then stop and exit.
Send one ICMP packet (per host) each interval seconds. This can be a floating-point number to specify sub-second precision.
