Yep, that's what I did.

Tried this, but think it is over my head. Any chance you can give me
the "For Dummies" directions :-)

Thanks.

They where on other ports then 3050. There where about 4 service
listening on 0.0.0.0 and 3 listening on 127.0.0.1,
All where different ports, so 3050 is available and being used by FB.

See comment above.

Actually I am not to bad with vi. I didn't check the /etc/hosts file.
What should be in there?

There is a localhost , 127.0.0.1

Here is some info from tcpdump (suggested by the folks over in the XEN
list server). 143.0.0.88 is my computer. linux1fb.webonedeveloper is
the server.
