Subject: [nncp-devel] Pipe option for addrs / nncp-daemon?

Hi,

One of the neat properties of Taylor UUCP is that one can run the thing
over just about anything.  I'm not saying modem support would be helpful
in NNCP, but I wonder if a transport that takes a pipe could be added?
I'm thinking of situations in which firewall ports aren't necessarily
open, but other methods may be.  For instance:

neigh foo:
  addrs:
    main: "| ssh foo nncp-daemon -pipe"

Of course, this would permit methods other than ssh as well.  Here I
think of things like low-bandwidth radio links, etc.

The -pipe option above may be very similar, or even identical, to
-inetd, I would imagine.

Why not nncp-bundle?  Well, a couple reasons; the two big ones being not
being resumable and not having a positive acknowledgment of being
received on the other end.

One other reason for doing this might be to facilitate independent
installations on a system (see my other message regarding user/group
ownership and permissions).  Say you have a "main" nncp on a system,
running out of /var/spool/nncp, but you want individual users on the
system to not necessarily have to sudo or use other weird tricks to use
it.  You could set up local neighbors like so:

neigh:
  user1:
    addrs:
       main: "| sudo -Hu user1 nncp-daemin -cfg /home/user1/nncp.yaml -pipe"

and user1 could presumably send everything via the local main with a TCP
connection or something.  This prevents the hassle of having to figure
out how to run an instance for every local user.

(As a random aside, should the log file be rotated by the usual system
logfile rotation tools?)

Thanks again!

- John
