Oping uses ICMP packages (better known as "ping packets") to test the reachability of network hosts. It supports pinging multiple hosts in parallel using IPv4 and/or IPv6 transparently.

This package contains two command line applications: "oping" is a replacement for tools like ping(1), ping6(1) and fping(1). "noping" is an ncurses-based tool which displays statistics while pinging and highlights aberrant round-trip times.
