6 oping - send ICMP ECHO_REQUEST to network hosts

10
11 oping [-4 | -6] [-c count] [-i interval] -f filename
12
14 oping uses ICMPv4 or ICMPv6 ECHO_REQUEST packets to measure a hosts
15 reachability and the network latency. In contrast to the original
16 ping(8) utility oping can send ICMP packets to multiple hosts in
17 parallel and wait for all ECHO_RESPONSE packets to arrive. In contrast
18 to the fping utility (URL is listed in "SEE ALSO") oping can use both,
19 IPv4 and IPv6 transparently and side by side.
20
22 -4 Force the use of IPv4.
23
24 -6 Force the use of IPv6.
25
26 -c count
27 Send (and receive) count ICMP packets, then stop and exit.
28
29 -i interval
30 Send one ICMP packet (per host) each interval seconds. This can be
31 a floating-point number to specify sub-second precision.
32
33 -t ttl
34 Set the IP Time to Live to ttl. This must be a number between (and
35 including) 1 and 255. If omitted, the value 64 is used.
36
37 -I address
38 Set the source address to use. You may either specify an IP number
39 or a hostname. You cannot pass the interface name, as you can with
40 GNU's ping(8) - use the -D option for that purpose.
41
42 -D interface name
43 Set the outgoing network device to use.
44
45 -f filename
46 Instead of specifying hostnames on the command line, read them from
47 filename. If filename is -, read from "STDIN".
48
49 If the real user ID (as returned by getuid(2)) and the effective
50 user ID (as returned by geteuid(2)) differ, the only argument
51 allowed for this option is "-" (i. e. standard input). This is
52 meant to avoid security issues when oping is installed with the
53 SUID-bit.
