Step 4. Creating FTP Users

In order for an HPSS user to use FTP, a UNIX and/or Kerberos userid and password must be created.
Refer to Section 3.3.2.1: The hpssuser Utility on page 35 for information on how to use t he hpssuser
utility to create the userid and password and set up the necessary configuration for the user to use FTP.
Note that this step should not be done until the Core Server is running so that t he hpssuser utility can
create the home directory for the FTP user.
The /opt/hpss/bin/hpss_pftppw utility can be used to set the encr ypted passwords in the
/var/hpss/etc/passwd file. The syntax for this utility is as follows:
hpss_pftppw <userid> [<password file pathname>]
The utility will prompt the user for the old and new passwords. If root has to change the pas sword it is
necessary to manually edit the file and remove the existing encrypted password. The password file
pathname argument can be used to specify a password file other than the default file,
/var/hpss/etc/passwd.
To enable anonymous FTP, the “hpssftp” user must be defined in either the HPSS FTP password file or
in the Kerberos KDC and LDAP registry (depending on which authentication mechanism is enabled). In
addition, the entry for the “hpssftp” user must contain a home directory defined to be a non-NULL
value. Anonymous FTP users will have the "root" directory set to "/anonymous" to prevent anonymous
users from accessing other portions of HPSS. This means that for anonymous access the director y
/anonymous MUST exist!
To disable anonymous FTP, either:
1. Remove the hpss_anon class from the ftpaccess file
- and/or -
2. Add hpss_ftp, anonymous or guest to the HPSS FTP user file (normally
“/var/hpss/etc/ftpusers”).
Security Policies and a knowledge of the security requirements should be carefully examined
and thoroughly understood before allowing "anonymous" FTP.

This section provides an overview of the HPSS VFS Interface. It describes the process to prepare the
environment, install the VFS Interface software, mount and unmount file systems, and discusses the
utilities available to manage the interface.
