I would like to install ISP Config on redhat Enterpise Linux Version 4 Workstation (WS) version. I dont have the server version of redhat. Is this installation possible?
Generally yes. If the ISPConfig installer does not recognize your operating system, you can try to replace the /etc/redhat_release file temporarily with a file from ContOS or Fedora while you install ISPConfig.
Your OS not supported ! With RH 4 WS ISP config the setup program sees " Your Operating System not supported". I tried the RH Enterprise Linux ES V 3 and I got the same message. Where can I find the right release file?
