wu-ftpd security

[Steve Johnson <steve@webninja.com>]

Hi,
I'm using wu-ftpd and set up /etc/wu-ftpd/ftpaccess to allow only one
user(using the deny-uid and allow-uid directives).  I also added a
'restricted-uid myuser' flag.  Everything is worknig fine, but I'm
confused.  It's chrooting (or appears to) that user to it's home
directory just as I would hope for, but there is no /home/myuser/bin,
/home/myuser/etc or /home/myuser/lib dirs?  Yet when I ftp in with ncftp
from another machine, I am chrooted, and I'm able to `ls' and run other
commands?  How is that?  Is it really chrooted, and/or secure?

Thanks in advance,
Steve
