OPING(8)
NAME
oping - send ICMP ECHO_REQUEST to network hosts
SYNOPSIS
oping [-4 | -6] [-c count] [-i interval] host [host [host ...]] oping [-4 | -6] [-c count] [-i interval] -f filename noping [-4 | -6] [-c count] [-i interval] host [host [host ...]] noping [-4 | -6] [-c count] [-i interval] -f filename
DESCRIPTION
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.
- -c count
- Send (and receive) count ICMP packets, then stop and exit.
- -i interval
- Send one ICMP packet (per host) each interval seconds. This can be a floating-point number to specify sub-second precision.
- -t ttl
- 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.
- -I address
- 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.
- -D interface name
- Set the outgoing network device to use.
- -f filename
- 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.
