Jeff,

>you restart the ldm on thelma?

Yes.  The time stamps on ldmd.conf and the ldmd.pid file coupled with
the allow content of ldmd.conf verify this:

/local/ldm% dir etc/ldmd.conf
    722587 -rw-r--r--   1 ustaff     10410 Apr  4 10:15 etc/ldmd.conf
/local/ldm% dir ldmd.pid
    685991 -rw-rw-r--   1 ustaff         6 Apr  4 11:36 ldmd.pid

allow   ANY-WSI-NLDN    frost.wunderground.com
allow   ANY-WSI-NLDN    ^(berry|whirlpool)\.wunderground\.com$
allow   ANY-WSI-NLDN    ^(sleet|ingestor)\.wunderground\.com$

I am seeing connection denied messages in thelma's LDM log file:

Apr 04 19:42:57 thelma.ucar.edu rpc.ldmd[29330]: gethostbyaddr: failed for 
66.28.250.166
Apr 04 19:42:57 thelma.ucar.edu rpc.ldmd[29330]: Denying connection from 
66.28.250.166

When I saw your original email, I checked to see if I could do a
name lookup for berry.wunderground.com:

(laraine.unidata.ucar.edu) 790 % nslookup -sil berry.wunderground.com
Server:         128.117.140.62
Address:        128.117.140.62#53

Non-authoritative answer:
Name:   berry.wunderground.com
Address: 66.28.250.166

and this incorrectly satisfied me that berry was set to go.
I just checked the reverse lookup and see that it is failing:

(laraine.unidata.ucar.edu) 793 % nslookup -sil 66.28.250.166
Server:         128.117.140.62
Address:        128.117.140.62#53

** server can't find 166.250.28.66.in-addr.arpa: NXDOMAIN

So, this is the problem.

Can you check into the DNS setup for berry?  This is where the problem
lies.

Jeff,

You should be good to go for feeding DIFAX from mapmaker.
Let me know of any problems.
