-------------------------------------------------------------------------------- hi there will i b able 2 install on Redhat 9 or Centos4??
Not sure about RH9 but I managed to get it working on CentOS 4.1 with help from this post: http://www.howtoforge.com/forums/showthread.php?t=470 I have not fully tested but it seems to be running okay.
RedHat 9 is supported (look here: http://www.ispconfig.org/manual_installation.htm ). CentOS 4 will be supported starting with the next ISPConfig release (2.0.9).
