Contreras First - why did you remove/change the line for your loop back interface? it's a baaaaaaad idea to not have 127.0.0.1 there... Other than that, your litener config seems ok... that together with the "Connection reset by peer" error message you're getting makes me think its a issue with the process not starting up correctly... Try again after you fixed your hosts file and then check the messages log, memory and disk usage. I assume you changed your kernel parameters according to the oracle docs? Peter.
