[Koha] koha with and without internet connection

Bonjour, Even though I know that it is rather an apache question.... How to configurate apache/koha to be able to use it even if the computer is not on the network? I have installed koha on a laptop which was on the network and without this connexion, I get an error message: http://name-on-the-network:80 connection refused... http://localhost:80 I get the apche default page. Thank you for any help. -- François Patte Ecole française d'Extrême-Orient - Pune - Inde Université René Descartes - Paris 5 UFR de mathématiques et informatique http://www.math-info.univ-paris5.fr/~patte
