   Yeah. Not always but the majority of the time an incoming IP will open up   
   telnet   
   Sessions on all available nodes. BBBS is hardcoded to wait for 4 minutes for a   
   login    
   before closing the node. This happens every 3-5 minutes lately. I have   
   blocking IP,s   
   in BBBS but the IP,s come in faster than I can add them. Most from China so   
   far.

   Im looking at some third party firewall solutions that support DoS and   
   connection   
   limiting. Since Windows itself doesn't have thos capabilities.
