Hi Alan,

Both you and Jeff see this message, I think Jeff mentioned to me he sees it
often.  I don't see it that often (who knows why, not as many idiots hitting
my servers??)  We both use iptables to ward off jerks, I'll show you the lines
I use for iptables at the end of this message.

In the past when this did happen to bbbs over here, restarting the bbbsd
daemon helped.  I generally kill the daemon and restart it about every two
weeks just out of habit.  To clear the whatevers, if you know what  I mean :)

Understand.   I checked my inet.log and don't see any connections from
???.???.etc.

The first thing I do after a reboot of the _system_ is iptables -F and iptables
-X to clean out the automatically installed iptables.  Then after that I send
the following commands:

REM example:  iptables -A INPUT -s IP-ADDRESS -j DROP
So I kill yandex.com and also semrush.com because they hit my system every
day, and often like this:

iptables -A OUTPUT -p tcp -m string --string "yandex.com" --algo kmp -j REJECT

Then I use a different line to stop idiots from smashing my HTTPD bbbs mailer
like this (two steps)
One:
sudo iptables -I INPUT -p tcp --dport 8090 -i eth0 -m state --state NEW -m
recent --set

Two:
sudo iptables -I INPUT -p tcp --dport 8090 -i eth0 -m state --state NEW -m
recent --update --seconds 60 --hitcount 2 -j DROP

8090 is the port I have always used for BBBSD.  You would change that to the
port you use for bbbsd.

Hope this helps :)

Take care,
Janis
