[pgpool-general: 1123] Re: Configuring pgsql nodes

dpkg -l | grep arping
ii  arping                             2.11-1
sends IP and/or ARP pings (to the MAC address)

arping -h
ARPing 2.11, by Thomas Habets <thomas at habets.se>
usage: arping [ -0aAbdDeFpqrRuv ] [ -w <us> ] [ -S <host/ip> ]
              [ -T <host/ip ] [ -s <MAC> ] [ -t <MAC> ] [ -c <count> ]
              [ -i <interface> ] <host/ip/MAC | -B>

no -U and -w microseconds :)

So what -U is doing anyways?
