Hi Greg,

	I've never messed with this on a Cobalt but a few months ago I
decided to see if we could get this kind of thing under some level of
control and I found that we could: man inetd - you can set, for example,
the maximum number of simultaneous invocations of a service, the maximum
number of times a service can be invoked from a single IP address in one
minute (very useful, for example, for a business site setup with multiple
users using POP/IMAP off a LAN) and more. While you only have a limited
amount of control I've personally found that if you work the numbers a bit
you can keep things down to a low roar quite easily. We only have 1 RAQ2
left here and most of this stuff is not supported on it but I have done
this on FreeBSD 4.7 and RedHat 7.3 so there's, I think, a possibility that
the inetd on your machine provides the needed bells and whistles.

	Best Regards,

	Brent
