Samba Connection Refused?

I've installed samba-3.0.9-1_rh9.i386.rpm on my machine, and now would like to fire
up Samba. smbd is running. I'm using "Linus Networking" HowTo on the web, chapter 10.
The author is Peter Harrison. On page 5, he talks about the SWAT file. I've
incorporated the two statements:

disable = no
only_from=localhost 192.168.0.2

The IP address is the one I use for my machine. The other machines are at 192.168.0.1
(linux) and 192.168.0.3 (XP). For the moment only 2 and 3 are online.

According to the test I can fire up swat from a browser, Moz, in my case. I've tried
with the following three URLs:
http://127.0.0.0:901 --> msg: Connection refused when trying to contact ...
http://192.168.0.2:901 -->msg: Document contents are empty ...

He makes some remark about "192.168.1.100 from PC 192.168.1.3" but it's not clear to
me what this is about. He uses 192.168.1.3 in the only_from, but I have no idea what
this ...100 address is about.
