Subject: SMTP LZW oddity
To: TCP-Group@UCSD.Edu, nos-bbs@hydra.carleton.ca
In all the code I've seen (apart from my own modified versions),
the SMTP LZW exchange goes like this:
Client sends "XLZW <x> <y>"
Server checks that it can do LZW with these parameters, if so it
replies with "25n XLZW <m> <n> OK" and goes to compressed mode.
The client checks the response, and iff (m = x) and (n = y) then
it too goes to compressed mode.
My question is: why does the client check <m> and <n> ? It's too
late for the client to decide to not go to compressed mode - the
server has already gone compressed.
The server code looks as though, in theory, it could return different
values from those the client supplied.
There may not necessarily be a problem in practice, but from a
protocol point of view the exchange seems wrong.

I need to configure ka9q as a DNS. The version that I have does not appear
to support DNS. Therefore which copy of ka9q or other variety of
nos do I require to produce a DNS
