:this patch. I'm thinking seriously of removing the ICMP_BANDLIM
:option as an option (eg compile the code in no matter what), but
:raising the limit from 100 to 1000 or something like that so it won't
:normally impact people, but those desiring to harden their servers can
:drift the number downward.

:Comment?

I'd increase the default to 200, no higher. 1000 is probably too
high a rate.
I found a bug in the patch:
: #endif
:- if (IN_MULTICAST(ntohl(ip->ip_dst.s_addr)))
:- goto drop;
:+ if (IN_MULTICAST(ntohl(ip->ip_dst.s_addr)) ||
:+ IN_MULTICAST(ntohl(ip->ip_src.s_addr)) ||
:+ IN_EXPERIMENTAL(ntohl(ip->ip_src.s_addr)))
: #ifdef INET6
: if (isipv6) {
: MALLOC(sin6, struct sockaddr_in6 *, sizeof *sin6,
In the above section, the 'goto drop' was removed. Shouldn't that stay
in? The body of this 'if' statement is now the conditional that
follows it, which is not what I think you meant to do.
