NAMEftpasswd - manipulates ProFTPD authentication files
SYNOPSISftpasswd --help|-h|--version ftpasswd --hash [ --des|--md5 ] [ --stdin ] [ --use-cracklib[=path] ] ftpasswd --passwd [ -F|--force ] [ --file=filename ] [--gecos=string ] [ --gid=gid ] [ --des | --md5 ] [ --not-system-password ] [ --stdin ] [ --use-cracklib[=path] ] --home=path ftpasswd --group [ -F|--force ] [ --enable-group-passwd ] [ --file=filename ] [ -m|--member ] [ --des|--md5 ] [ --stdin ] [ --use-cracklib[=path] ] --gid=gid ftpasswd --passwd --change-password --name=username
DESCRIPTIONftpasswd 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 pass‐ word 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".
OPTIONS-F, --force If the password or group file be used already exists, delete it and write a new one. --file=filename Write output to specified file (password or group files), rather than default one. --gecos=string Descriptive string for the given user (usually the user's full name). --gid=gid Set primary group ID for this user (optional, will default to given --uid value if absent) when --passwd is specified. --uid=uid numerical group ID. -h, --help, --version Show usage and version of the program. --home=path Set the home directory for the user (required). --des, --md5 Use the DES or MD5 algorithm for encrypting passwords. The latter is the default. --name=username, --name=groupname 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=path Shell for the user (required). Recommended: /bin/false --change-password Update only the password field for a user. This option requires that the --name 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. --not-system-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 access. --stdin Read the password directly from standard in rather than prompting for it. This is useful for writing scripts that automate use of ftpasswd. --use-cracklib[=path] 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 speci‐ fies the path to the dictionary files to use -- default path is /usr/lib/crack‐ lib_dict. This requires the Perl Crypt::Cracklib module to be installed on your system. --enable-group-passwd 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.
