FTP Services, aka "pubftp"
ITD Unix Services provides an FTP server transporting large
blocks of data into, out of and around the Laboratory's internal
network. This service is open to all employees of the
laboratory and may be accessed at any time. There are
limitations to using the ftp server however, and these are mainly to
address security concerns with FTP.
- How to Access an ITD Hosted FTP site
- Limitations
The primary cause of FTP's inherent insecurity is that login
credentials are sent in the clear, or unencrypted. As a
result, Cybersecurity has mandated
that all FTP sites must be anonymous. Anonymous FTP allows a
user to log in with either username "anonymous" or "ftp" and then
enter their email address as their password. As a result of
this log-in method anyone may log in and upload or download data.
Start your preferred FTP client (examples: WS_FTP, FileZilla,
gFTP).
When prompted for log-in information, use the following
credentials (in this example, the user connecting is John Doe, with
email address "jdoe@bnl.gov"):
username: anonymous
password: jdoe@bnl.gov
hostname: ftp.bnl.gov
port: 21
After logging in, you should observe a blank directory listing.
You may now upload or download files.
Once connected you may upload a file or files to the FTP server.
After upload, anyone who knows the file name may download the file.
For example, if you upload a file to ftp.bnl.gov
with the name "test.txt", then anyone may then download that file
with an FTP client or with a web browser using the URL
ftp://ftp.bnl.gov/test.txt.
All uploaded content must conform to the Brookhaven National
Laboratory
Computer Use Agreement.
It is advised that uploaded files be less than 10GB in size.
Keep total data size under 100GB.
Users are unable to create directories or subdirectories on the
public FTP server.
ITD limits directory listings. Users must know in advance
the name of the file or files they wish to download. The user
uploading a file is responsible for notified other users of that
file's full path and file name. This is to helps prevent
malicious users from using the FTP site as a repository for
inappropriate data.
All files on the public FTP server are automatically deleted 7
days after creation. If a file is still needed after 7 days, a user
may upload the file again. ITD reserves the right to delete
any files which exceed or fall outside stated policies above.
