Using the cxs Installer Script
Once we have informed you that your license has been activated, you can install cxs. First perform the following in a root shell on your server via SSH:
cd /usr/src rm -f cxs* wget https://download.configserver.com/cxsinstaller.tgz tar -xzf cxsinstaller.tgz perl cxsinstaller.pl ipv4 rm -fv cxsinstaller.*
Then you must follow the installation instructions in /etc/cxs/install.txt from step 2 onwards.
