Ispconfig is open source hosting panel used by many Hosting providers.Though Cpanel is best , Ispconfig is also far better than other free hosting panel.By defalut the admin panel of Ispconfig is accessed by using http://ip-addresss:8080. If any one using Ispconfig I first suggest to change that port to another for security reason.For changing 8080 is quite easy. Follow the steps for this:
1.Open your terminal and login as root.
2.vi /etc/apache2/sites-enabled/000-ispconfig.vhost
here you will see as : Listen 8080
NameVirtualHost *:8080
Now change 8080 as your desired port. For e.g. 8000
Similarly change 8080 in sites-available also.
Then restart your apache2. Now browse Ispconfig in new port as http://ip-addresss:8000.
Cheers
