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.
