Ping contains routines to test for the reachability of remote hosts. Currently the only routine implemented is pingecho().

Ping.pingecho uses a TCP echo (not an ICMP echo) to determine if the remote host is reachable. This is usually adequate to tell that a remote host is available to telnet, ftp, or ssh to.

Warning: Ping.pingecho may block for a long time if DNS resolution is slow. Requiring ‘resolv-replace’ allows non-blocking name resolution.

Usage:

  require 'ping'

  puts "'jimmy' is alive and kicking" if Ping.pingecho('jimmy', 10)
