NAME

6       oping - send ICMP ECHO_REQUEST to network hosts
7

SYNOPSIS

9       oping [-4 | -6] [-c count] [-i interval] host [host [host ...]]
10
11       oping [-4 | -6] [-c count] [-i interval] -f filename
12

DESCRIPTION

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

OPTIONS

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.
