On the SYNDefender firewall..... if we are interested in firewalls, then the 'elegant firewall solution' is, IMO, to insure that our gateways send ICMP UNREACHABLE messages back to the host. Then it is somewhat easy to do the kernel checks to free SYN_REVC 'zombies'
It would also make it easier to nuke vital network communications paths. Thanks, but I'll pass. Perry - - - - - - - - - - - - - - - - -
