I followed the instructions (http://www.howtoforge.com/perfect-server-ubuntu-9.10-ispconfig-3-p5) on an existing linux server. I find I cannot access squirrelmail or ispconfig on port 8080, even through the lan IP. I don't find an /etc/init.d/ispconfig_server mentioned in some of the google searches i did. netstat -a | grep ispconfig returns nothing. I am at a loss. What do I try next?
