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,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. setuid will not work for --fwmark. ## 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.) ## Credits * Original author: Roland Schemers (schemers@stanford.edu) * Previous maintainer: RL "Bob" Morgan (morgan@stanford.edu) * Initial IPv6 Support: Jeroen Massar (jeroen@unfix.org / jeroen@ipng.nl) * Other contributors: see [CHANGELOG.md](CHANGELOG.md)
