[IDD #NQN-650121]: LDM/IDD feeds from RAL

Hi Gary,

"Standard" LDM installations have a generic ALLOW line for unidata.ucar.edu
machines.  Please check to see if you have this as one of, if not the first
ALLOW lines:

# Give permission to the Unidata Program Center
ALLOW   ANY     ^[a-z].*\.unidata\.ucar\.edu\.?$        .*

If you have this line (capitalization of ALLOW is not important), you do
not need any other for machines in the unidata.ucar.edu domain.

> We use IDD as our primary upstream feed, these feeds don't seem necessary.

Agreed that it is unlikely that you would feed these specific machines.
ALLOWing any machine in the unidata.ucar.edu, on the other hand, helps us
troubleshoot problems for users' machines.

The three listed are not important; the general allow for unidata.ucar.edu
machines is.

Here is the contact information:

f5.aos.wisc.edu        - UW/AOS, Pete Pokrandt <poker@@meteor.wisc.edu>
sunset.meteor.wisc.edu - also in UW/AOS, so Pete Pokrandt is the contact
unidata.ssec.wisc.edu  - this machine no longer exists.  unidata2.ssec.wisc.edu
                         however, is the machine that generates and relays the
                         Unidata-Wisconsin datastream (IDD UNIWISC aka MCIDAS 
stream)
                         The contact for unidata2 is either Unidata User Support
                         or the SSEC Data Center <address@hidden>

> allow   ANY-NLDN-PCWS-FSL3     tea.mmm.ucar.edu

OK.  I agree with RAL not acting as a relay site for NCAR/UCAR machines.  It
should, however, whenever possible act as a relay for machines in its own 
domain,
rap.ucar.edu.

> Thanks,

No worries.

Cheers,

Tom
