Yes. We are seeing it here bigtime. Does anyone have any apache hacks to lessen the impact? One idea: Once a probe is sent, the prober's IP# is stored in a hash (perhaps in shared memory or a mmap'd file that all children can share) and new connections from that IP are no longer accepted.
Or better: script which causes a filter rule to be added to ipchains list, blocking all ports. ----------------------------------------------------------------- Daniel Senie dts@senie.com Amaranth Networks Inc. http://www.amaranth.com
