What is 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 very long history: Roland Schemers did publish a first version of it in 1992 and it has established itself since then as a standard tool for network diagnostics and statistics.

Announcing version 3

There was no official fping release from 2002 until end of 2011. Various patches existed, but were never integrated "upstream". Also, the official maintainer didn't answer emails, so I decided to just step up and take over maintenanceship. If you feel that I did wrong, please contact me.

To mark this change of maintenance, and avoid confusion, I decided to call it version 3. Besides a new maintainer, fping now also features a completely rewritten main loop implementation which improves performance significantly. The run time is now close to the theoretical time required to send and receive the pings under the specified parameters.

fping 3.0 includes the following changes, compared to the last released version 2.4b2-to-ipv6:
