Weeeeell, apart from several Replies to the Effect of "where'd you
get SATAN / Perl 5.0", there was only one Response from John Hearns
<> who thinks that the SATAN Docs recommend
turning off TCP Wrappers before running SATAN. I remember differently
(just try avoiding Finger Wars), plus, it's not an Option for healing
*other People's* SATAN Runs. (Which is why I haven't investigated
the Effect of newer SATAN Versions on this Issue, either.)

For the Time being, I've set up a procmail Rule to prevent another
153,000 Alert Mails Surprise:

# Destroy unwanted Email right away
# -- SATAN tends to make inetd on SunOS 4.x mad. Let *some* of the Mails
# pass (10 Seconds Window per Hour) to alert me
* ^From: nobody
* ^Subject: ALERT-rpc.ttdbserverd-unknown
* !^Date: .*:00:0

(where the Subject is what TCP Wrapper Alert Mails on rpc.ttdbserverd
caused by SATAN look like under my TCP Wrapper Setup).

More Info still welcome.
