-# = ping.rb: Check a host for upness
-#
-# Author:: Yukihiro Matsumoto
-# Documentation:: Konrad Meyer
-# 
-# Performs the function of the basic network testing tool, ping.
-# See: Ping.
-#
-
-require 'timeout'
-require "socket"
-
-# 
-# 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)
-#

-  # 
-  # Return true if we can open a connection to the hostname or IP address
-  # +host+ on port +service+ (which defaults to the "echo" port) waiting up
-  # to +timeout+ seconds.
-  #
-  # Example:
-  #
-  #   require 'ping'
-  #
-  #   Ping.pingecho "google.com", 10, 80
