Ftp server configuration

[Fabrizio_10]

Hello,

I tried to configure my ftp server ((FTP server (Version 1.1.214.4(PHNE_23950))without succes regarding chroot user.
I would like to create only an ftp access, without shell, for user pro. I've just added /usr/bin/false to my /etc/shells and after I've added the user with /usr/bin/false shell.

Now, I wuold like to chroot this user only to his directory /home/pro .
Could someone sugget me how to do it?

Thanks a lot

You need to use the ftpaccess file (man ftpaccess), if you are using HP-UX 11.00 or higher (wu-ftp if 10.20), for the directory access issue. Other than that you have in essence an ftp only account because you have /usr/bin/false as their default shell.

Check out these docs:

A generic ftpaccess file is in /usr/newconfig/etc/ftpd . You can use it to customize to your environment.

Hope this helps

Hi again,

here's my ftpaccess.

...
# cdpath
cdpath /incoming
cdpath /pub
cdpath /

...
guestgroup ict

and this is my /etc/passwd related to chroot user:

pro:"password":6071:3029::/bmd/input/./:/usr/bin/false

When I logged with pro users I see this:

Password:
230 User medpro logged in. Access restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> pwd
257 "/" is current directory.

But the directory should be /bmd/input and not / .

My /etc/shells contains all type shell, also /usr/bin/false.
My inetd was modified with -a option.
Thanks again!

Oops sorry!
I forget a step in previous post:

I do it for chroot user:

mkdir usr
mkdir usr/bin
cp /usr/bin/ls usr/bin/ls
chmod -R 555 usr
chown -R bin:bin usr

but I see this error:

ftp> ls
200 PORT command successful.
150 Opening ASCII mode data connection for /usr/bin/ls.
crt0: ERROR couldn't open /usr/lib/dld.sl errno:000000002
226 Transfer complete.

Why ?

When copying the ls binary, use /sbin/ls, not /usr/bin/ls. the former is not dynamicly linked.

Thank you Tom & others, now ftp server, works fine with chroot.
