File transfer using Anonymous FTP at MSFC
An Anonymous FTP Server is a type of server which handles a special
network protocol called ftp (File Transfer Protocol). It is accessed using
an FTP client. Examples of FTP clients are:
-
Spry Network File Manager (Windows)
-
Fetch (Macintosh)
-
ftp (DOS and UNIX command line)
-
Web Browsers (such as Netscape) are also FTP clients but they can
only download and upload files (Vers 3.0 or later Netscape), not delete
them. If using a browser, please configure your email address in the proper
location in the browser's preference.
A full featured FTP client must be used to delete files.
Our Anonymous FTP Server
has a public access directory (/pub) under which there are directories
for each NASA center. These directories are used as a drop box and
are accessable without a password. It is most useful for transfering relatively
large files to remote sites. Disk space is provided on a first-come, first-served
basis. The maximum size is 200mB. On occasion, the anonymous or /pub directory
fills up and users must wait until a daily automated batch job deletes
any files older than five (5) days. Anyone can log in as the anonymous
user and read/add/delete the files in the dropbox. There are no access
restrictions.
Sensitivity/Criticality Level for this server is "0" which means
the inaccuracy, alteration, disclosure, or unavailability of data provided
by this service would have a negligible impact on NASA's missions, functions,
image, or reputation.
When transferring a file, the sender and receiver should coordinate
so that when the file is placed in the /pub/site directory, it can be picked
up as soon as possible. This is desirable because speedy deposit, retrieval
and deletion minimizes the waiting period for someone else who otherwise
might need to wait as long as five (5) days before there is space freed
up.
To transfer files, one can follow the steps given here:
(If using a browser such as Netscape, the URL is ftp://ftp.msfc.nasa.gov)
