Tools - fping-rust

fping-rust was an attempt to port the original C program fping to Rust.
Some features are missing, but others are included.

In theory, it can be used with common tools such as smokeping

This version is licensed under the GPL

Installation

To use this, rust-lang must be installed https://rust-lang.org/ 

cargo install fping-rust

Make fping either setuid, or, if under Linux

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-rust in rootless / unprivileged containers. 

echo "net.ipv4.ping_group_range = 0 2147483647" >> /etc/sysctl.d/local.conf

  -t, --timeout      Timeout in ms (default: 500) [default: 500]
  -r, --retry       Number of retries (default: 3) [default: 3]
