Apparently, ncdump doesn't support OpenDAP URI's of 56
characters or more in length. Consider, e. g.:$ ncdump -k http://nomads.ncep.noaa.gov:9090/dods/gfs_hd/gfs_hd20110128/gfs_hd_00z ncdump: http://nomads.ncep.noaa.gov:9090/dods/gfs_hd/gfs_hd20110128/gfs_hd_00z: NetCDF: I/O failure $ I've checked the proxy logs, and no HTTP request is recorded upon the command above. The behavior is the same should the URI be truncated to 56 characters: $ ncdump -k http://nomads.ncep.noaa.gov:9090/dods/gfs_hd/gfs_hd20110 ncdump: http://nomads.ncep.noaa.gov:9090/dods/gfs_hd/gfs_hd20110: NetCDF: I/O failure $ On the other hand, the URI's of 55 characters and less are handled differently, and the requests are being made: $ ncdump -k http://nomads.ncep.noaa.gov:9090/dods/gfs_hd/gfs_hd2011 ncdump: http://nomads.ncep.noaa.gov:9090/dods/gfs_hd/gfs_hd2011: NetCDF: DAP server error $ ncdump -k http://test.opendap.org:8080/dods/dts/test.01 64-bit offset $ -- FSF associate member #7257
