[Xastir] Need Linux Networking Help

[Rich Garcia]

This is the largest group of Linux experts that I know of so I am asking
here. Anyone want to give me a hand understanding some Linux networking
and SMB concepts ? I have searched the web and still can't find answers
on 2 specific questions. 

Please reply directly and not on the list since it is off topic.
Thanks!
