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.
noping is an ncurses-based front-end to liboping which displays ping
statistics online and highlights aberrant round-trip times if the terminal
supports colors.
OPTIONS
-4
Force the use of IPv4.
-6
Force the use of IPv6.
-ccount
Send (and receive) count ICMP packets, then stop and exit.
-iinterval
Send one ICMP packet (per host) each interval seconds. This can be a
floating-point number to specify sub-second precision.
-tttl
Set the IP Time to Live to ttl. This must be a number between (and
including) 1 and 255. If omitted, the value 64 is used.
-Iaddress
Set the source address to use. You may either specify an IP number or a
hostname. You cannot pass the interface name, as you can with GNU's
ping(8) - use the -D option for that purpose.
-Dinterface name
Set the outgoing network device to use.
-ffilename
Instead of specifying hostnames on the command line, read them from
filename. If filename is -, read from "STDIN".
If the real user ID (as returned by getuid(2)) and the effective user ID (as
returned by geteuid(2)) differ, the only argument allowed for this option is
``-'' (i. e. standard input). This is meant to avoid security issues when
oping is installed with the SUID-bit.
