General Usage

Lftp operates rather similarly to the old command line ftp utility. You should do a module load lftp first, and then connect to a remote site using lftp -u REMOTE_USERNAME REMOTE_SITE. You will be prompted for a password if needed, and then you will enter the interactive lftp prompt. At this point you can enter any of the many commands supported. The help command shows a quick overview of all the commands, we will discuss a few of the most commonly used ones below: (in the following, local site means the system on which you invoked the lftp command, and remote site is the site you specified with with REMOTE_SITE argument to the lftp command):

The following example shows some of the commands for accessing Box:

login-2:~> module load lftp
login-2:~> lftp -u USERNAME@umd.edu ftp.box.com
Password: Enter your Box external application password here
lftp USERNAME@umd.edu@ftp.box.com:~> help

    cat [-b]                      cd 
    chmod [OPTS] mode file...            close [-a]
    [re]cls [opts] [path/][pattern]      debug [OPTS] [|off]
    du [options]                   edit [OPTS]

    ls []                          mget [OPTS]

Using with UMD Box

One of the protocols supported by UMD Box is ftps, making lftp a good choice for connecting to box. We discuss a few aspects of using lftp with Box here. See the UMD Box service catalog entry for more information on the Box service, including restrictions on what data can be stored.

When connecting to UMD Box over the ftps protocol, the standard campus directory name/password single-sign-on cannot be used, so you will need to set up in Box a password for external applications. To do this:

  1. From a web browser on your desktop/laptop/etc, go to umd.box.com and log in using the UMD single sign-on (your standard UMD campus directory ID and password).
  2. In the upper right is an icon (usually either your image or initials) with a drop down menu; open the menu and select "Account Settings".
  3. Under the "Account" tab, there is a section called "Authentication". There should be a link to the right entitled "Create Password" (if you already created your external password, the link will be called "Change Password". You can use this if you forgot what your external password is).
  4. Click the "Create Password" link and enter your password for accessing Box. Use a different password than your main UMD and other passwords.
  5. Click on "Save Changes" near the top right.
    Do not re-use your main UMD directory single-sign-on or any other password for your UMD Box external application password. Re-use of passwords is a security risk, since if you reuse passwords and hackers compromise one site they can then leverage that to compromise additional sites.

    After your external application Box password is set up, you can then access Box with a command like lftp -u USERNAME@umd.edu ftp.box.com.
