-R 0 -s your_ad_can_be_hereYour cure is worse than the disease: rate limiting allows a DoS against the service, no limit allows a DoS against the whole machine.-s limits number of processes invoked from same IP. You can additionally use -c to prevent distributed attack. It doesn't allow to DoS box and doesn't disable service for 10 minutes.
Note that my (DEC/Compaq/HP Tru64) inetd does not have -c or -s options. The only safe way is to use a sensible -R and tcp_wrappers. Or upgrade to Linux and xinetd...
