I'm setting up a multiserver setup, master with everything and two name servers. The master and primary name server are OK. I was installing ispconfig on the second name server, but had to press control-C in the middle of the installation, after "Configuring BIND" and Configure Web Server (which I answered yes and wanted to correct). Now second try for the ispconfig install fails, with I tried running ispconfig update.php, but that can not run since the files are not yet installed. How to solve this?
