[comp.mail.uucp] Sources of UUCP-e-Protokoll

clu@malihh.hanse.de (Carsten Lutz) (04/12/91)

Hi !

Could anyone please mail me a source of the UUCP-e-Protocol ? ( And only
that please, I don't need anything about g and f stuff ! )

I would like to implement it and don't know exactly how it works yet.
I think there are 20 bytes sent for every file with the following contents:

1234\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0
^^^^               ^
 |                 filled with chr(0)'s
 Length in ascii-notation.

then the file is sent. The only errorchecking is testing the length of
the received file. If it is not Ok the connection is closed and the file
erased. 

But how do the cicos know wich one is to send and wich one to receive a
file ? And is there any init-sequence ?

Greetings,
                Carsten

The "real" source belongs to AT&T. You cannot get a copy without a System V
source license.

It sounds like you are pretty close to reverse engineering it, though. It's
a very simple protocol. Just watch the packets on a scope; you'll figure it
out very quickly. If you already have source for 'f' (which is public domain),
you can follow the same model.

I hope you mean a protocol description and not source code.  Otherwise
you are most likely asking somebody to violate a license agreement.  I
believe that 'e' protocol was an enhancement that was part of
HoneyDanBer UUCP (now known as the System V Basic Networking
Utilities).  This is not public domain stuff.
