OK.  Some informational comments:

- the combination of PPS, DDS, HDS and IDS is the 'IDS|DDPLUS'
  feed

- I think you meant FNEXRAD, not FNEXRAS

- LIGHTNING data is only available as point-to-point feeds from the
  sites that make the data available: UAlbany for NLDN and WSI Corp.
  (now known as the Weather Company) for the USPLN data

- I don't think you want the NTEXT or NGRAPH data

- NXRDSRC is the same as NEXRAD2

- if you get all of the data in all of the feeds listed, you would be
  receiving a LOT of data

  To illustrate this, here is a snapshot from one of the real server
  backend machines for the top level IDD relay cluster that we operate
  here in UCAR:

Actions:

- I will update our LDM/IDD contact list with the information you provided above

- I just verified that your new machine has both forward and reverse DNS

  This means that you should be ready to go as soon as the LDM/IDD 
administrators
  for the machine(s) that you REQUEST data from are alerted to update their
  LDM ALLOW configurations to allow you to REQUEST the data you want.

  At some time in the past, you were getting LDM/IDD feeds from Iowa State.
  The Iowa State that relays IDD data is now metfs1.agron.iastate.edu.

  Other sites that you can REQUEST data from are:

  idd.tamu.edu            - Texas A&M
  idd.meteo.psu.edu       - Penn State
  idd.unl.edu             - UNebraska at Lincoln
  idd.unidata.ucar.edu    - UCAR/Unidata

  These sites should now ALLOW your feed REQUEST(s).  You should test to make
  sure that this is the case by, for example:

  <as 'ldm' on geoprdldmap.cc.ku.edu>
  notifyme -vl- -f ANY -h idd.tamu.edu

Please let us know if/when you have any questions...

Cheers,

Tom
