# fping
|
|
|
|
|
|
|
|
|
|
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.

## Installation
|
|
|
|
|
|
|
|
|
|
If you want to install fping from source, proceed as follows:
|
|
|
|
|
|
|
|
|
|
0. Run `./autogen.sh`
|
|
|
|
|
(only if you got the source from Github).
|
|
|
|
|
1. Run `./configure` with the correct arguments.
|
|
|
|
|
(see: `./configure --help`)
|
|
|
|
|
2. Run `make; make install`.
|
|
|
|
|
3. Make fping either setuid, or, if under Linux:
|
|
|
|
|
`sudo setcap cap_net_raw+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.
|
|
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
|
|
|
|
|
|
Have a look at the [fping(8)](doc/fping.pod) manual page for usage help.
|
|
|
|
|
(`fping -h` will also give a minimal help output.)
