Didn't work, when I do this it then floods the logs of a message about the IP in question trying to modify the permanant arp entry. *sigh* > -- > Rod Grimes - KD7CAX @ CN85sl - (RWG25) rgrimes@gndrsh.dnsmgr.net This is driving me bonkers. It is making my logs less than useless.

While I am relieved to know I don't have to PAY for this crap, it doesn't help me. I am getting this message every 30 seconds or so, on the average. If I type dmesg, all it is is the error. Does anyone have any suggestions at all on how I can suppress this? Jamie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
