Re: 11 years of inetd default insecurity?

Your cure is worse than the disease: rate limiting allows a DoS against the
service, no limit allows a DoS against the whole machine.

Isn't that the point of system administration, to set reasonable values for such things. A balance between a reasonable load and a full DOS attack on the service or machine must be achieved.

I don't see how this feature is bad as long as its used properly. Besides many people run multiple services on a host.. if you set the value to unlimited all services are DOS'd. For instance, I have a system running apache, sendmail, and imapd. imapd is spawned by inetd and therefore could be DOS'd with a limit. By setting a limit though, my apache and sendmail servers stay up. I think this is a no brainer.
