Virtual Hosting With Proftpd And MySQL (Incl. Quota)

[SkY`]

I checked.
From the "client" I do this:

sky@Lara:~$ ftp 192.168.1.2
Connected to 192.168.1.2.
220 ProFTPD 1.3.0 Server (Debian) [192.168.1.2]
Name (192.168.1.2:sky): master
331 Password required for master.
Password:
530 Login incorrect.
Login failed.

And the log records:

found.

This line explains everything:

May 31 23:40:07 xxx.xxx.xxx proftpd[19528] xxx.xxx.xxx (192.168.1.4[192.168.1.4]): USER master (Login failed): No such user
found.

it looks like you dont have user called "master" or you have it but in the db it contains whitespaces...

[SkY`]

Yes, but there is an user named 'master' in both the 'ftpquotalimits' and 'ftpuser' tables...

I configured my proftpd/mysql as described in the howto but now have the problem that ftp logins do not work.
As long as the Shell is set to "/sbin/nologin", login does not work. In debian etch /sbin/nologin does not exist, but /usr/sbin/nologin, changing the shell in mysql doesn't have an effect, changing it to /bin/false also not.
Only when I change the shell to /bin/bash the login works.

What am I doing wrong?

It seems that your Proftpd expects system users, not virtual users. Please make sure that your setup is exactly like the one from the tutorial (check for typos, etc.).

Dear Falko,

thanks for your reply. I couldn't find typos, I copied the config from the howto into my files. See my conf:

[falko]

And the MySQL username and password are correct?
Does the virtual user exist also as a system user?
