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??Wink 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 Smile

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

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 and also because they hit my system every day,
and often like this:

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

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

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 Smile

Take care,
