use bluetooth with LAN profile

[Zhang Weiwu]

I'm new to bluetooth. I read the handbook bluetooth chapter several time, 
but I don't think I really get it:( 

Okay, let me try to explain it so please you can tell me if I have some 
concepture problem:

To let several other bluetooth device (notebooks) to access my LAN, that is 
"LAN access for multiple Bluetooth devices". So I need to have a server, on 
this server I need to run rfcomm_pppd and sdpd. Each other notebook connect 
to my server's bluetooth card, and establish a single rfcomm connection, 
that is to emulate a serial connection between the notebook and the server. 
Finally I'll have several virtual serial connection to my server, for 
several bluetooth notebook. And on these serial connections I need to run 
ppp on client side and pppd on server side. Am I correct?

But I have a problem: is sdpd part of the sdp-1.5 package? I cannot find 
this package on port tree. The handbook suggest me to get the package from 
<http://www.geocities.com/m_evmenkin/> but geocities is not accessable from 
China. This site has been blocked for several years for political reasons. 
Can I get the package elsewhere? "sdp bluetooth" is not a good google 
keyword to find it.

Thank you!
