What is linux.conf? (From my question, you probably guessed that I have never changed it.) Nor have I changed any other scripts. Have you even tried the steps I outlined? I have run JBoss AS on RHEL 4, SUSE 9, FC4, FC5 and FC6, and in every case the steps I have outlined previously have worked. Caveats: I always unzip the JBoss AS zip file into /opt (yielding, for example, /opt/jboss-4.0.5.GA). (Well, not always, I often download the source distribution of grab the source straight from Subversion and compile it myself, but even those always go into /opt or /opt/jboss.) I always did this as my own login id (not as root), so I did have to first grant myself access to /opt. And when I ran JBoss AS I ran it as my own login id. On every machine I have had root access. But you don't even need that if you install JBoss AS in your home directory. By default, JBoss AS does not use any of the reserved IP ports (1..1023), so running as non-root is not an issue. As long as you run the browser from the same machine and use http://localhost::8080 to access the server, or run client apps on the same machine and use port 1099 to access JNDI (and various other ports such a 1098, 4444 and 4445), you don't even need to configure your firewall. Once again I am wondering what exactly it is that you are attempting to do. And no, determining what configuration files to change is NOT your goal. Changing configuration files is what you assume you need to do to accomplish your goal. Perhaps if you could clarify your actual goal... (So far, I have assumed that your goal is to install JBoss AS, which is what you specified in your second post.)
