Hi all, I just tested poink on FreeBSD 3.1-RELEASE, and the machine has a minor problem and then recovers. As people pointed out, arp is arp and it really shouldn't hose systems much. I haven't tried out extensive tests yet... maybe later in the evening when I have more time. :) Here's my log file: Apr 19 14:39:32 <foo> /kernel: arp: <baz> is using my IP address <mumble>! Apr 19 14:39:32 <foo> last message repeated 16 times Apr 19 14:39:32 <foo> /kernel: Apr 19 14:39:32 <foo> /kernel: arp: <baz> is using my IP address <mumble>! Apr 19 14:39:32 <foo> last message repeated 2 times (<foo> -> your machine, <baz> -> your ethernet addr, <mumble> -> your ip addr :) ) The next thing that happened was that ypbind complained for a bit (NIS server not responding) and amd was unhappy. The machine always responded to pings, but my home directory disappeared temporarily. In about a minute, everything returned to normal (AFAIK). I'd guess that a repeated-poink, or a poink of an nfs server would be a more serious problem. -Rajit To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
