Initial Comment:
Hi,
cURL fails to download from some FTP sites, such as
ftp://ftp.cdc.noaa.gov/Datasets/ncep.reanalysis/README
or any other file at that domain (this usually gets
"curl: (56) FTP response reading failed", however it
randomly works some times). This is because their FTP
server uses a reverse name look-up (i.e.
http://www.cdc.noaa.gov/PublicData/faq.html#8 ). I've
only had success by using Mozilla Firefox and manually
downloading [hundreds of] files. It does not work with
the stock 'ftp' command (error message is "Connection
closed by remote host."), nor with 'wget'.

My WinXP SP2 computer has an assigned or static IP
address (if this matters).

curl 7.15.1 (i686-pc-cygwin) libcurl/7.15.1
