   BBBS and Telnet Logins?   
   28 Jan 15 23:11:22   
   
   Hi Jeff,   
      
   >>> In BBBS is it possible to limit the time BBBS will wait at a telnet login   
   >>> prompt before the login is aborted and the node closed?   
      
   >> That's a good question... Did you hear back from Kim about that?   
      
   > Yes, and forwarded his response to you. He stated that BBBS is hardcoded to   
   > wait 4 minutes at the login prompt before closing the node.   
      
   Yes, makes sense.   
      
   >>> Is there a way in BBBS to limit or prevent BBBS from opening up all   
   >>>available nodes via telnet or FTP login attempt? Currently BBBS opens up all   
   >>> available nodes based on a single incoming telnet IP.   
      
   >> I looked at my logs and the version I'm running doesn't do that from what I   
   >>can tell.. For instance, I ran a grep of an IP that had connected via telnet,   
   >>didn't log in,then disconnected, and I only found this IP in one log, which I   
   >>assumed meant he'd only connected to one node. What do your logs show? Do you   
   >> see the same IP in all logs like log3, log4, log5, etc. (or how ever many   
      
   I see multiple logins though with HTTP this evening.   
      
   > Here my IP log shows BBBS spawning multiple telnet nodes with all showing the   
   > same source IP. Per a suggestion from Kim. I am running two seperate BBBS   
   >daemons. One for HTTPD, FTPD, and RAW/BINKP and a seperate daemon for TELNETD.   
   >As in "bbbs 2 2 telnetd:23". That should only make node #2 available for telne   
   > use. Leaving any other available nodes unavilable for telnet use. I also   
   > inquired about upgrading to 20 nodes.  Gots the upgrade app already filled   
   >out and ready to be emailed to Kim. Sadly upgrading doesn't solve the problem.   
   >It just makes for more available nodes. But may lessen the impact somewhat. We

   Yes, really a firewall, fail2ban, and inet.bbb is all that we can really do.   
      
   Take care,
