ftpasswd is a Perl script which can be used to manipulate
the password and group files suitable for use with
ProFTPD AuthUserFile and AuthGroupFile configuration directives.
The idea is somewhat similar to Apache's htpasswd program.
Required options are --passwd, --group, or --hash.
These specify whether ftpasswd is to
operate on a passwd(5) format file, on a group(5) format file, or simply
to generate a password hash, respectively.
If used with --passwd, ftpasswd creates a file in the passwd(5) format,
suitable for use with proftpd's AuthUserFile configuration directive.
You will be prompted for the password to use of the user, which will be
encrypted, and written out as the encrypted string.
By default, using --passwd will write output to "./ftpd.passwd",
If used with --hash, ftpasswd generates a hash of a password, as would
appear in an AuthUserFile. The hash is written to standard out.
This hash is suitable for use with proftpd's UserPassword directive.
If used with --group, ftpasswd creates a file in the group(5) format,
suitable for use with proftpd's AuthGroupFile configuration directive.
By default, using --group will write output to "./ftpd.group".
If the password or group file be used already exists, delete it and write a new one.
Write output to specified file (password or group files),
rather than default one.
Descriptive string for the given user (usually the user's full name).
Set primary group ID for this user (optional, will default to
value if absent) when
numerical group ID.
-h, --help, --version
Show usage and version of the program.
Set the home directory for the user (required).
Use the DES or MD5 algorithm for encrypting passwords.
The latter is the default.
Name of the user account or group (required).
If the name does not exist in the specified output-file, an entry will be created
for it. Otherwise, the given fields will be updated.
Shell for the user (required). Recommended:
Update only the password field for a user. This option
requires that the
option be used, but no others.
This also double-checks the given password against the
user's current password in the existing passwd file, and
requests that a new password be given if the entered password
is the same as the current password.
Double-checks the given password against the system password
for the user, and requests that a new password be given if
the entered password is the same as the system password. This
helps to enforce different passwords for different types of
Read the password directly from standard in rather than
prompting for it. This is useful for writing scripts that
automate use of ftpasswd.
Causes ftpasswd to use Alec Muffet's cracklib routines in
order to determine and prevent the use of bad or weak
passwords. The optional path to this option specifies
the path to the dictionary files to use -- default path
This requires the Perl Crypt::Cracklib module to be installed on your system.
Prompt for a group password. This is disabled by default,
as group passwords are not usually a good idea at all.
-m username, --member=username
user to be a member of the group. This argument may be used
This argument may be used multiple times to specify the full list
of users to be members of this group.
