Sorry, if this is somewhat off topic, but I haven't found a ucspi-tcp list. (and nothing approriate searching with search engines ;-) Has someone written an addon to tcpserver that allows control of connection frequency based on ip addresses? I am thinking of something like specifing 1.2.3.4 20 connects per 10 minutes If that limit is hit tcpserver would either deny the connection or start an optional other program e.g. smtpreject which could send 220 mail.example.com and a 451 too many connections as an answer to sucessive commands.
