extraits de man ftpaccess :
guestgroup <groupname> [<groupname> ...]
guestuser <username> [<username> ...]
realgroup <groupname> [<groupname> ...]
realuser <username> [<username> ...]
For guestgroup, if a REAL user is a member of any of
<groupname>, the session is set up exactly as with anonymous
FTP. In other words, a chroot() is done, and the user is no
longer permitted to issue the USER and PASS commands.
<groupname> is a valid group from /etc/group (or whatever
mechanism your getgrent(3) library routine uses).
The user's home directory must be properly set up, exactly as
anonymous FTP would be. The home directory field of
the passwd entry is divided into two directories. The first
field is the root directory which will be the argument
to the chroot(2) call. The second half is the user's home
directory relative to the root directory. The two
halves are separated by a "/./".
For example, in /etc/passwd, the real entry:
guest1:<passwd>:100:92:Guest
Account:/ftp/./incoming:/etc/ftponly
When guest1 successfully logs in, the ftp server will
chroot("/ftp") and then chdir("/incoming"). The guest user
will only be able to access the directory structure under /ftp
(which will look and act as / to guest1), just as an
anonymous FTP user would.
