     If not mode R,P,J,M,S or O is informed, default icmp behavior, RTA and packet loss

     The -H switch is optional. Naming a host (or several) to check is not.

     When defining multiple addresses they must be provided as the last argument.

     Threshold format for -w and -c is 200.25,60% for 200.25 msec RTA and 60%
     packet loss.  The default values should work well for most users.
     You can specify different RTA factors using the standardized abbreviations
     us (microseconds), ms (milliseconds, default) or just plain s for seconds.

     The -v switch can be specified several times for increased verbosity.
