NAME

       privatepw - Change WU-FTPD Group Access File Information

SYNOPSIS

       privatepw [-c] [-f ftpgroups] [-g group] accessgroup

       privatepw [-d] [-f ftpgroups] accessgroup

       privatepw [-l] [-f ftpgroups]

       privatepw [-V]

DESCRIPTION

       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  (aka,  ftpgroups)  file.  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.

BACKGROUND

       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  (specified  by  the
       _PATH_PRIVATE define in pathnames.h).

       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.

OPTIONS

       -c     Create a new ftpgroups file.

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

       -g group
              Set the real system group to the group specified.  This is valid
              only when adding a  new  accessgroup  or  changing  an  existing
              accessgroup’s password.

       -f ftpgroups
              Use the specified ftpgroups file for all updates.

       -l     List the contents of the appropriate ftpgroups file.

       -?     Display a simple help usage message.

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