I found these log messages in my logs and I am not sure what some of them signify. Dec 23 19:08:39 smtp kernel: Limiting closed port RST response from 221 to 200 packets/sec Dec 23 19:08:40 smtp kernel: Limiting closed port RST response from 241 to 200 packets/sec Dec 24 05:32:34 smtp kernel: fxp0: promiscuous mode enabled Dec 24 05:32:49 smtp kernel: fxp0: promiscuous mode disabled Dec 24 05:33:01 smtp kernel: fxp0: promiscuous mode enabled Dec 24 08:18:44 smtp kernel: fxp0: promiscuous mode disabled Dec 24 12:48:57 smtp kernel: Limiting closed port RST response from 201 to 200 packets/sec I understand the "Limiting closed port RST response". ....but what are the promiscuous mode enabled and disabled on my NIC? I am not doing this, so who or what is doing this. Or better yet, what does this mean? I have a fear that this one is serious. So what I need is some direction into finding out how this occurs and what I can do to stop it. thanks, Bob
