  Translating 127.0.0.1 into "localhost.dom.ain" can cause some
      software to connect back to the loopback interface when it didn't
      want to because "localhost" is not equal to "localhost.dom.ain".

Thanks for the memo. Seems the solution is to not call machine localhost,
if insist in doing so, be sure it contains a "localhost.localdomain" line
in /etc/hosts.

I believe topic is closed with this.

Thanks
