   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
