3 oping - send ICMP ECHO_REQUEST to network hosts
7 B<oping> [B<-4> | B<-6>] [B<-c> I<count>] [B<-i> I<interval>] I<host> [I<host> [I<host> ...]]
11 oping uses ICMPv4 or ICMPv6 ECHO_REQUEST packets to measure a hosts
12 reachability and the network latency. In contrast to the original L<ping(8)>
13 utility B<oping> can send ICMP packets to multiple hosts in parallel and wait
14 for all ECHO_RESPONSE packets to arrive. In contrast to the
15 B<fping> utility (URL is listed in L<"SEE ALSO">) B<oping> can use both, IPv4
16 and IPv6 transparently and side by side.
24 Force the use of IPv4.
32 Send (and receive) I<count> ICMP packets, then stop and exit.
34 =item B<-i> I<interval>
36 Send one ICMP packet (per host) each I<interval> seconds. This can be a
37 floating-point number to specify sub-second precision.
39 =item B<-I> I<address>
41 Set the source address to use. You B<cannot> pass the interface name, as you
42 can with GNU's L<ping(8)>.
50 =item The TTL cannot be set
