It's called CHROOT:

put a ./ in the passwd file

user:xxxx:xxxx:........:/usr/home/user/./ftp

Ditch wu-ftp.

Use something like proftpd, or pure-ftpd: those have chroot jails.

No go. That stops the user from ftp'ing in at all.

What I found out was that wu-ftpd is no longer offered in RH's Fedora
series, and the only reason that it was installed on my system was
that I'd upgraded an existing RH7.2 box and it was sort of a legacy.
Switching to vsftpd solved the problem, as it's easy to configure.
Thanks, Asam and Dave, for the replies.
