spc> Has anyone else been seeing a dramatic increase in /scripts/.. NT worm spc> probes this morning? We're seeing about 8000/second, starting around 9:15 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. thanks, -joe
