Yes, I started the thread w/Trina...

It will be hard to get data moving if the host is not exposed :)

You will need to edit your ldmd.conf file, located in ~ldm/etc

..to indicate what feeds you want and where you are requesting them from.

i.e. 

request IDS|DDPLUS   ".*"    idd.unidata.ucar.edu


  I'm guessing you still need our IP address?

Yes, and a hostname would be good too, we can go off of solely the IP if the IP 
resolves..we prefer to have a hostname.

  I don't believe we have an actual host/domain name that's visible to the 
public, but I noticed the docmentation says a qualified hostname is required.  
Is just the IP address ok?  Or are you just using the IP to connect, and then 
using the internal hostname of the server for other actions?

Yes, see above comment.

RAWS = (Remote Automated Weather Station)

All surface obs are included in the DDS or PPS data stream, which has been 
consolidated to:

IDS|DDPLUS


which will have surface obs for the globe. The feed can be restricted
via a regular expression if you know what station(s) data you desire.

You would replace the ".*" with the expression that matches the station data 
you desire.
