I downloaded ispconfig and than I read the instructions to istall it. Here is the instructions: Code: Log in to your shell as root. Unpack the ISPConfig-archive tar xvfz ISPConfig*.tar.gz and change to the directory install_ispconfig: cd install_ispconfig In this directory please check the file dist.txt and see if the values given there suit to your Linux installation (they should be suitable for standard installations). If you change any values please be sure not to change the format of the file. Then start the setup-script from there: ./setup After I put ./setup it tells me that the operating system is not supported. If I change it to fedora core 4 will it work?
