[ferret_users] Grib on OPeNDAP via proxy

["Paulo B. Oliveira" <pbo@xxxxxxxxx>]

Hi all,

Is there any trick to use Grib files on a OPeNDAP server ?

My web access is via a local http proxy.

I've tried to use the files in: 
http://data.nodc.noaa.gov/opendap/ncep/rtofs/2010/201001/ofs.20100131/surface/contents.html

$ ferret
 	NOAA/PMEL TMAP
 	FERRET v6.5  
 	Linux(g77) 2.4.21-57.ELsmp - 04/01/10
 	23-Apr-10 11:43     

yes? use
