Hello,

I want to use Proftpd for my ftp-server, but I want two sorts of users to connect, normal users and anonymous users. I want anonymous users to connect to another port than the normal users. Anonymous users can download from a Public folder en can upload to an Incoming folder. I also want normal users to remove files from the Incoming folder.

Is this possible? If it's yes, can you help me pleasee?

Thanks, Chrizziej

Have you looked at:
-proftpd's man pages?
-the proftpd.org website, especially the example configurations & FAQ? http://www.proftpd.org/docs/example-conf.html
I'm using vsftpd myself, so I can't help you. But it should be possible to allow both real users and the "anonymous" user and to define separate upload/download permissions for both.

As for connecting the different users to different ports: I'm not sure what you mean by that (please elaborate/give example). FTP uses different ports for control and data connections, which also depend on active vs passive ftp mode.

I allready looked there. The problem is the userpermissions and the different ports:

I want normal users to connect to port 21 (default port) and I want anonymous users to connect to port 4000. I don't want the problem that all kinds of anonymous users can connect to my ftp-server.

Then disable anonymous ftp altogether.
Hackers/spammers/... often use port scanners to find out open ports (that's really easy).
So theyyour port 4000 will be found and used by users you don't want.

If you insist, you might want to have a look at tcpwrappers and other stuff like that.
