Subject: Re: I can't access remote ascii
data with DODS
Hi,
Ferret is DODS enabled such that it has a built-in DODS NetCDF
client. When Ferret sees 'http...' in the ffilename for the
command 'SET DATA filename' it assumes that the data is DODS served and
the NetCDF client takes over reading the data. The Ferret 'file' command
expects local files only.
Currently, the server at http://127.0.0.1/cgi-bin/nph-dods/
seems to be down. What results do you get when you use theh ferret
command,'SET DATA "http://127.0.0.1/cgi-bin/nph-dods/asc.dat"'?
