Listener issue

Question

Hi forum members, In this moment I'm working on gentoo linux and I' new in oracle, I could install oracle and created a test database called "oracle.gentoo" , but I don't know if the listener it's really registering a service in order to access to the database with a java program , because the listener says "LISTENER SUPPORTS NO SERVICES" , some of the listener message are:

Something wrong with hostname configuration or in listener.ora,
but it should also work if you specify explictly in your
listener.ora:
Add in ADDRESS_LIST section an entry, so it will listen on
192.168.1.71 address also, like:
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL= TCP)(Host=192.168.1.71)(Port= 1521))
