ftpgroups - group password file for use with the SITE GROUP and SITE
The ftpgroups file is the group password file for use with the SITE
GROUP and SITE GPASS commands.
To enable the use of this file, the entry private yes must be made in
the configuration file /etc/ftpd/ftpaccess.
This file contains an alphanumeric string, encrypted password, and the
actual group name from the /etc/group file. Each entry is separated
by :. After a 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 setgid()) a member of the group specified in the group access
The format of the group access file is:
where access_group_name is an arbitrary (alphanumeric and/or
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.
NOTE: For this option to work for anonymous FTP users, the ftp server
must keep /etc/group permanently open and the group access file is
loaded into memory. This means that:
(1) the ftp server now has an additional file descriptor open,
(2) the necessary passwords and access privileges granted to
users via SITE GROUP will be static for the duration of an FTP
If you have an urgent need to change the access groups and/or
passwords *NOW*, then kill all of the running FTP servers.
