The ftp server funtionate now. Thanks very much for the help. Seems to be an gerneral problem of proftp and fedora. I reinstalled the whole system and installed proftp first. After i tried the proftp setup and it worked.
If have some questions concering adding modules to the web server. Where I have to do the modules like mod_python etc that the right web server find the modules. And which httpd.conf file i have to edit? Is it possible some how to turn them on or off out of ISPConfig.
Does a software installer to install php/perl packages exist in or for ISPConfig?
Something like Fantastico for cPanel or Elefante Installer from Resellerpanel.com or the installer from SW-Soft!
