 NAME    [Toc]    [Back]
      privatepw - Change WU-FTPD Group Access File Information

 SYNOPSIS    [Toc]    [Back]
      /usr/bin/privatepw [-c]  [ -d accessgroup ]  [ -f ftpgroups ]
           [ -g group accessgroup ]  [-l]  [-V]

 DESCRIPTION    [Toc]    [Back]
      If a site supports the SITE GROUP and SITE GPASS commands, it is
      necessary to be able to add, delete and list enhanced access group
      information. The privatepw utility is used to update this information
      in the group access file (/etc/ftpd/ftpgroups).  This is meant as an
      administrative tool and not to be run by the general user population.
      This command requires read/write permission to the appropriate
      ftpgroups file.

    Options    [Toc]    [Back]
      In the options defined below, accessgroup is an alphanumeric name
      specified to a group. Please see the Background section for details.

           -c             Create a new /etc/ftpd/ftpgroups file.

           -d accessgroup Delete the specified accessgroup information from
                          the ftpgroups file.

           -f ftpgroups   Use the specified ftpgroups file for all updates.
                          If this option is not specified by default it
                          takes the /etc/ftpd/ftpgroups file.

           -g group accessgroup
                          Set the real system group (defined in /etc/group)
                          to the accessgroup specified.  This is valid only
                          when adding a new accessgroup or changing the
                          password of an existing accessgroup.

           -l             List the contents of the appropriate ftpgroups
                          file.

           -V             This option causes the program to display
                          copyright and version information, then terminate.

    Background    [Toc]    [Back]
      After user logs in, the SITE GROUP and SITE GPASS commands may be used
      to specify an enhanced access group and associated password. If the
      group name and password are valid, the user becomes (via setegid()) a
      member of the group list in the group access file
      (/etc/ftpd/ftpgroups)

      The format of the group access file is:

      access_group_name:encrypted_password:real_group_name

      where access_group_name is an arbitrary (alphanumeric + punctuation)
      string.  encrypted_password is the password encrypted via crypt(3),
      exactly like in /etc/passwd.  real_group_name is the name of a valid
      group listed in /etc/group.
