Stupid Question, But don't know.

This might be a stupid question, but here goes. I need to setup Ftp access to a linux server. I have already added the user and set up the Home dir. But how do i lock them in the home dir? Basically so they can't back out and see other dirs. Thanks.

Depends: Whats your ftpd-the generic bsdftpd or something like wu-ftpd or proftpd?

Hi,





With wu-ftpd this is not a simple as you might like unfortunately. You basically have to set up a chroot jail, i.e. you create a minimal environment somewhere in the directory tree (e.g. under /home/ftp/) where there is a minimal linux environment such that the user's root directory can be made to be at that point. So /home/ftp appears as '/' to such users and they can't navigate beyond that. See -->

http://www.landfield.com/wu-ftpd/docs/guest-howto.html.

I would suggest looking at proftpd which is much more helpful in these kind of areas. It has features such as virtual hosts (similar to Apache). You can use directives like :

<VirtualHost myhost.mynet.foo>
DefaultRoot /home/ftp/public ftpusers
...
</VirtualHost>

The above would jail all members of the linux security group 'ftpusers' to /home/ftp/public

For proftpd downloads look at -->

and for documentation

.

Hope this helps

I am a little confused, but let me add something to this. We are running a web server for some of or friends and i want to lock them into there own home dir that they upload for the web pages. Would i have to download a separte Ftp program for Linux or can i use the one that comes with it?

Thanks in advance

Use proftpd :

http://www.proftpd.net

The configuration syntax is identical to apache's conf.
syntax.
