samba - Mar 2005 - implementation issues

Hello all,
I am a final year computer engineering student.
As part of my BE project I am working around with Samba server (version 2.2.7a)
I wish to understand following implementation issues:
 
 1. When and in what condition does a Samba server fork?
 2. What is the significance of the connection_structure? 
 3. Why is a doubly linked list of instances of the connection_structure are
maintained?
 4. While running in interactive mode,an error occurs 'registers not
obtained,permission        denied',What does this error signify?
 5. Can anyone tell me the way in which to understand the execution flow of
samba server?

Please help me out.
Thanking u, 
Regards,
nac?

you should probably be looking at Samba 3.0.x rather than 2.2.x
for study.  Or use Samba 4 for research purposes.

child smbd processes are forked per tcp session.  See
smbd/service.c:open_sockets_smbd()

|  2. What is the significance of the connection_structure?

It represents a connection to a file or lanman printer service.

|  3. Why is a doubly linked list of instances of

a single session may have issued multiple tcon requests
and there may have more than on active share connection.

I don't see this error anywhere.

You'll have to read the source for this one.  That's
a little broad of a question for a short email response.




cheers, jerry
