Hi,
I have just released fping 3.10:
* Fix confusing error message with -g and IPv6 addresses (#58, reported by Axel Beckert)
* Allow option '-f' also for non-root (since setuid privileges are dropped)
* Do not retry twice DNS lookup on DNS lookup problem
* Remove support for NIS groups
* Better document -B backoff-factor and when it can be used (#33, Oleksiy Zagorskyi)
* More tests added
You can download it here:
