asked on
sublogin in anonymous ftp using user command
With wu-ftpd, when anonymous users ftp in and try a
sublogin with the "user" command, they get this message:
Can't change user from guest login.
Is there a way to allow sublogins for anonymous ftp?
Are there any security issues by allowing sublogins in
anonymous ftp?.

guestgroup <groupname> [<groupname> ...]
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 wher-
ever your getgrent() call looks).
