PRIVATEPW(8)


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.
