[McIDAS #LMK-679192]: NFS-mounts not supported by ADDE MODIS server?

Hi Tyn,

Good to hear from you.  I hope you are well and happy!

re:

This is completely surprising to me.

Not off of the top of my head.  The difference in the two situations (AREA file
vs non-AREA file) is the server code that handles each is different.

Please send me the IMGLIST output while trying to access each dataset
defined by the RESOLV.SRV entries above:

<as 'user' where the MODIS dataset is defined>
cd $MCDATA
rm -f trce
IMGLIST MODIS/MXD021KM FORM=ALL TRACE=1

-- send the output from IMGLIST and the contents of the
   file 'trce'

rm -f trce
IMGLIST MODIS/MOD021KM FORM=ALL TRACE=1

-- send the output from IMGLIST and the contents of the
   file 'trce'

re:
> Hardlinks are not supported on the debian lenny distro.

There should be no difference between soft and hard links.

If the IMGLIST and 'trce' output is not illuminating, would it
be possible for me to get one or two example data files of the
type that are failing so that I can examine the situation in detail?

Cheers,

Tom
