Hi,
I could give you an answer. Depending on you OS, in Solaris, no -H but $HOSTADDRESS$ that's how
it's passing the argument; while in Aix, -H is must. I'm not sure in Linux how it goes. Of
course, it's better put -H in all Unix platform for consistence, that's why I made a mistake in
the beginning.
Hope it helps.
