[pgpool-general: 1124] Re: Configuring pgsql nodes

my arping comes from http://www.skbuff.net/iputils/
 -U     Unsolicited ARP mode to update neighbours' ARP caches.  No
replies are expected.
-w deadline
              Specify  a timeout, in seconds, before arping exits
regardless of how many packets
              have been sent or received. In this case arping does not
stop after  count  packet
              are sent, it waits either for deadline expire or until
count probes are answered.


I'm guessing yours comes from here, and seems to be a completely
different implementation:
