I followed Falco's great instructions (The Perfect Server - Ubuntu 12.04 LTS (Apache2, BIND, Dovecot, ISPConfig 3)) pretty much to the letter but when I get to the last page which says to go here:
FireFox just says "Unable to connect".

I actually used localhost:8080 and https://localhost:8080 and got the same non-result with both.

The installation also says you can start the service as a startup job but doesn't give the name of the job? Is it ispconfig, ispconfig3, ispconfig 3 or what?

The installation also set up a cron job. I tried running the command as root
/usr/local/ispconfig/server/server.sh > /dev/null 2>> /var/log/ispconfig/cron.log
. It didn't seem to do anything and made no entry in /var/log/ispconfig/cron.log

Also, ps -e | grep isp shows nothing.

So what's going on? How do you get ispconfig running?
