Hi, Just installed CentOS 3.3. I said to allow only http and ssh when I did the install. I can ssh to the machine and until I compiled apache 2 and installed it seperately I could connect to the default web server. I am running oracle on the box and have found that I can't connect remotely to oracle from another linux box (sql*net works fine on the CentOS box itself). I think it is because the port (oracle is on 1521) is blocked. Can anyone give me an idea of where to start? I've looked at hosts.deny/allow and they both contain no entries and I can't find anything in /etc that seems to be involved in the problem. Thanks, Wayne
