Not yet. I am planning to implement this. One question is where to store
the passwords. It is impossible for the nntpd to retrieve passwords from
/etc/shadow because it is not a privileged process, and I would be quite
reluctant to give up this additional level of security. The choice would
probably therefore be to have a separate password file owned (and readable)
by user "news".

If you use tcp-wrapper (as you should) you can tweak them to log as much
information as possible by putting the following stuff into /etc/hosts.deny
leafnode: ALL EXCEPT LOCAL
and into /etc/hosts.allow
This will deny access to leafnode to everybody coming from outside
provided that leafnode is started from the /etc/inetd.conf with
nntp stream tcp nowait news /usr/sbin/tcpd /path/to/leafnode
If the last entry in the /path/to/leafnode is, for example, in.nntpd
instead, you have to change the "leafnode" in /etc/hosts.deny and
For further documentation of tcp wrappers, I refer to their man pages:
hosts_access(5) and hosts_options(5). There should also be programs
called tcpdchk (which checks the configuration of your tcp wrappers)
and tcpdmatch (which checks how a specific request would be handled)
which also have manpages.
