[Samba] Do I need two instances of Samba on the same machine (3rd request) ?

[John H Terpstra]

Dani,

Have you followed chapter 4 of the Samba-Guide (Samba-3 by Example book)?
What does not work? I am in the process of updating this documentation and 
would much value your feedback.

You can download the current version from:

http://www.samba.org/samba/docs/Samba-Guide.pdf

I look forward to your feedback.

Cheers,
John T.

Oh? Why P-Node?

How many interfaces do you have? If there are only two, why limit the
