Please be aware that the URL of the *LOCAL* HDF Group ftp server will be permanently changing to: https://gamma.hdfgroup.org/ftp/ Previously, files could be obtained by using either the above address or: ftp://ftp.hdfgroup.uiuc.edu/ This change should not affect most users. The local ftp server is only used as a temporary means for obtaining snapshots and other files that are not part of the standard released software.
