If you do not enable some access controls for leafnode, people everywhere
will be able to use your news server, for things like posting spam or
accessing huge binary newsgroups. People activly scan the net for open news

If you do enable access controls, this will prevent any computers except
localhost from accessing your news server. You can modify /etc/hosts.allow
later to broaden the access controls, if necessary.

The default scripts provided with the package now support an
intermittent PPP connection. If you set up for a PPP connection then
fetchnews will be started whenever a PPP link is brought up and any
running fetchnews processes will be killed when the link is dropped.
Otherwise, news will be fetched daily as before. Either setting will
work with a PPP connection managed by diald.
