Other Sysops have changed their telnet ports as well...but I'm
not sure how other telnet BBS software is handling these bots.
I set up a script that blacklists any IP that connects to a port
more than 5 times in a couple minutes. iptables blocks the
address for a few hours. If it continues trying after 3
temporary blocks, the IP is permanently blocked.
That can backfire on a legitimate caller, though... If my telnet
"dialer" times out on me, I will retry a time or two, possibly within
that couple of minutes.... certainly again within the next hour or
two, just in case things are just being slow... I think in some cases,
it may actually connect but so close to the timeout that I couldn't
tell for sure.... I'm using a DOS telnet client, Conex....
