Hmm...  Please check to see what IP address is associated with
adde.ucar.edu on chico:

SEE ADDESITE.TXT
 -- or --
SEE MCTABLE.TXT

If your listing shows that adde.ucar.edu has an IP of 128.117.15.119,
then run:

DATALOC HOST

and check again.  Also, please check to see if you have both
ADDESITE.TXT and MCTABLE.TXT.  If you do, check MCTABLE_WRITE to see
which one gets updated by DATALOC invocations.  It could be that you
have an entry in MCTABLE.TXT that is being used even though
ADDESITE.TXT is being updated by DATALOCs.

The name change for newmotherlode on Friday was _supposed_ to leave
adde.ucar.edu as 128.117.15.119, but it apparently didn't.  Here  is
the results of the above 'SEE' on my home development machine:

 ...
HOST_ADDE.UCAR.EDU=128.117.114.119
 ...

I am wondering if the name switch is playing havoc on machines that
still have DATALOCs pointing at adde.ucar.edu/128.117.15.119.

re: no listing from papagayo
>That's what I get back from adde.ucar.edu as well.

Weird given that I get back the expected list from another machine
running 2005.

Update:  I just logged onto papagayo and saw that Clint had changed
where non-N0R Level III products were being filed.  I just updated his
ADDE configuration and now get a valid listing for N1P:

DATALOC LIST RTNEXRAD

Group Name                    Server IP Address
--------------------         ----------------------------------------
RTNEXRAD                     PAPAGAYO.UNL.EDU

<LOCAL-DATA> indicates that data will be accessed from the local data directory.
DATALOC -- done
 
IMGLIST RTNEXRAD/N1P ID=LIST

IMGLIST: done

NB: Clint is only saving N0R products for every station.  For all
others he has the short list of sites shown above.

Yes, the global keyword to use is MCCompress (MCC= for short).

>Any other ideas?

Please try papagayo again from chico.  If that works, please check the
IP address being used for adde.ucar.edu on chico.  I suspect that may
be the problem area.  When I get in (leaving shortly), we can turn
debugging on so we can see what is happening on motherlode.

re: global keyword to use is MCCompress (MCC= for short).

Thanks.

PostScript:

The problem turned out to be a configuration error on adde.ucar.edu.
The replaceable token '\DATE' in RESOLV.SRV should have been replaced
with '\CURDAY'.  Once this was done, everything works from UPC
machines.

The question remains why a listing from my home machine worked without
error?
