Hello,

First, create an account (cdf) and give it a unique group id (i.e guestgroup).

In your ftpaccess file, create a class for this user and insert the guestgroup line:

class interfaces guest or , etc.

guestgroup

Then edit your /etc/passwd to giv it a chrooted home dir:

cdf:*:123:456::/home/cdf/./:/bin/false (make sure the default shell is present in /etc/shells.

Then make any appropriate entries in ftpaccess:

upload /home/cdf /incoming yes cdf 0660 dirs
upload /home/cdf / no

Also, mkdir usr/bin under the user's home directory and copy /usr/bin/ls into it and make $HOME/usr $HOME/usr/bin and $HOME/usr/bin/ls 555 permissions.

In case I forgot anything, look at these docs:

http://www2.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000063248362

Others may be obtained using the keywords "ftpaccess" and "ftp only"

Hope this helps

Hi,
can send your ftpaccess file as attachment?
And also show the config line for the cdf user from /etc/passwd?

regards,
John K.

Christopher has everything perfect...except one little problem.

Do not use usr/bin/ls...

Instead copy /sbin/ls to /home/cdb/usr/bin and then chmod it.

Rgrds,

Hello again,

What does your line for ftpd say in /etc/inetd.conf?

ftp stream tcp nowait root /usr/local/bin/tcpd ftpd -l -v -a -L -i -o

(keep in mind I'm using tcp wrappers, so your line might say ftpd instead of tcpd)

Have you tried bouncing inetd?

# inetd -c

Could you please post your ftpaccess file as requested before?

Chris
