I had this so have switched to port 24 and all hacking has stopped.

That hacking will return. They will find you again and start again. It seems
to be a proportional thing, fight and block them and they up the systems attacking you. If you can get it to just one node I'm leaving it that way at the moment and not even firewall-ing them out. When I did they attacked from bots in other places like Brazil, basically it didn't help. They attack my
2323 system less than the port 23 system, but they attack all of them. The
more you fight to keep them out the more they throw at you from what I've found.
