[Koha] Introduction and a question

[Stefano Barale]

Hello everybody!
First of all let me briefly introduce myself.

I am a physicist with roughly ten years of experience in the ICT field, 
eight of which in international and multi-cultural environments. I have 
a good background in web applications and IT research with extensive 
experience in all aspects of free and open source software, plus I have 
worked in recent years in the areas of technical training and 
instructional design.

During the last few weeks I started a project here in Turin, Italy that 
includes the creation of an ILS/OPAC for a foundation that bought a 
considerable number of books in Arabic. In order to build it up, Koha 
was chosen.
I made the first attempts to install the software on my local machine 
(running Ubuntu 10.10), just to start testing. After reading several 
docs I ended up with Apache replying my requests with this message:

System Maintenance
The Koha Online Catalog is offline for system maintenance. We'll be back 
soon! If you have any questions, please contact the Site Administrator 
<mailto:>

on the OPAC port, while I get:

Unable to connect

on the Intranet port.
I see that this is not a new problem, so please forgive me if I've 
missed the message that solves it all.
RTFM is an acceptable answer (just point me to some links, please :D )
Best regards,
Stefano
