fping is a program to send ICMP echo probes to network hosts, similar to ping, but much better performing when pinging multiple hosts. fping has a long long story: Roland Schemers did publish a first version of it in 1992 and it has established itself since then as a standard tool.

If you want to install fping from source, proceed as follows:
./autogen.sh
(only if you got the source from Github)../configure
with the correct arguments.
(see: ./configure --help
)make; make install
.sudo setcap cap_net_raw,cap_net_admin+ep fping
If you can't run fping as root or can't use the cap_net_raw capability, you can
also run fping in unprivileged mode. This works on MacOS and also on Linux,
provided that your GID is included in the range defined in
/proc/sys/net/ipv4/ping_group_range
. This is particularly useful for running
fping in rootless / unprivileged containers. The --fwmark option needs root or
cap_net_admin.
Have a look at the fping(8) manual page for usage help.
(fping -h
will also give a minimal help output.)
