okay finally I got it
. Just installed ISPConfig on a running Debian 3.1 Testserver. It's great! Looks very nice
and does it's job .. the next days I'll do more testing
For QA here some problems that occured during the installation
* "which httpd" failed because the executable was missing. A soft link form /usr/sbin/apache to /usr/sbin/httpd fixed this issue.
* The mysql socket file had another location. (don't remember the actual location and I have currently no access to the server). A soft link fixed this issue, too. Maybe this occured because I'm using the dotdeb.org MySQL-Packages.
Have a nice weekend and thanks for this great open source program!
