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> ...]]
9 B<oping> [B<-4> | B<-6>] [B<-c> I<count>] [B<-i> I<interval>] B<-f> I<filename>
13 oping uses ICMPv4 or ICMPv6 ECHO_REQUEST packets to measure a hosts
14 reachability and the network latency. In contrast to the original L<ping(8)>
15 utility B<oping> can send ICMP packets to multiple hosts in parallel and wait
16 for all ECHO_RESPONSE packets to arrive. In contrast to the
17 B<fping> utility (URL is listed in L<"SEE ALSO">) B<oping> can use both, IPv4
18 and IPv6 transparently and side by side.
26 Force the use of IPv4.
30 Force the use of IPv6.
34 Send (and receive) I<count> ICMP packets, then stop and exit.
36 =item B<-i> I<interval>
38 Send one ICMP packet (per host) each I<interval> seconds. This can be a
39 floating-point number to specify sub-second precision.
43 Set the IP Time to Live to I<ttl>. This must be a number between (and
44 including) 1E<nbsp>andE<nbsp>255. If omitted, the value B<64> is used.
46 =item B<-I> I<address>
48 Set the source address to use. You B<cannot> pass the interface name, as you
49 can with GNU's L<ping(8)>.
51 =item B<-f> I<filename>
53 Instead of specifying hostnames on the command line, read them from
54 I<filename>. If I<filename> is B<->, read from C<STDIN>.
