Anonymous FTP Access FTP Access to Online Volumes*Note: Most modern web browsers no longer support FTP, so an FTP client application or command line will need to be used to download files via FTP.FTP access to any Geosciences Node data set can be achieved by substituting "FTP:" for "HTTPS:" in the data set's URL. For example, from the LCROSS web page, clicking the link to CLIO Calibrated Data gets you to this location: https://pds-geosciences.wustl.edu/lunar/ear-l-mmto_clio-3-cdr-lcross-v1/lcrcli_1xxx/ The FTP path to these files: ftp://pds-geosciences.wustl.edu/lunar/ear-l-mmto_clio-3-cdr-lcross-v1/lcrcli_1xxx/ You may verify that the files you have downloaded are intact by comparing their checksums with the checksums of the files on the server. You'll find a checksum file in the root directory of each archive. Read more about checksums here. Our FTP server supports plain FTP, anonymous access through port 21, which is the default port used by most FTP services. An advantage of using FTP is that you can transfer multiple files at once, if you are using an FTP program that allows this. There are several FTP clients available for free that do this. SmartFTP and FileZilla are two such programs that we have used with success. If you use SmartFTP, you will need to change a few settings so that it will work properly with our FTP server. On the menu bar, go to Tools->Settings, then click on the Advanced tab and uncheck the boxes for Show Hidden Files, Force Long Format, and Resolve Links. This prevents SmartFTP from sending unnecessary messages that our server cannot understand. If you are behind a firewall, you may also need to go into the Settings window, click on the Connection tab and ensure that the "Use Passive Mode" box is checked. We have noticed that SmartFTP is not able to resume interrupted downloads when used with certain Internet Service Providers such as Earthlink.
