[opensuse] Connection being actively refused - error

I am setting up a Xen server and my first guest (DomU) is a Firebird server. It listens on port 3050. Every time I try to connect to port 3050 it is actively refuse, even when I am trying to connect locally through 127.0.0.1 How can I figure out what is misconfigured? I would like to trace were the request is being stopped / denied. I am an experienced computer user, but a newbie with Linux. Thanks for any help. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
