To eliminate the possibility of a real loop, the second ethernet interface is connected to a hub with no machines on it. However, I am still seeing messages like: Jun 30 16:24:48 zprime /kernel: -- loop (0) 00.60.97.88.38.68 to ed1 from ep0 (active) Even weirder are these: Jun 30 15:31:46 zprime /kernel: arp: 00:60:97:8f:d5:92 is using my IP address 66.120.218.4! Jun 30 15:31:46 zprime /kernel: xx ouch, bdg_forward for local pkt Of special note is that 00:60:97:8f:d5:92 is the ethernet interface of the second ethernet card (the one hooked to the empty hub). The two ethernet cards are: ep0: <3Com Etherlink III 3C589> at port 0x240-0x24f irq 9 slot 1 on pccard1 ed1 at port 0x300-0x31f irq 9 flags 0x80000 slot 0 on pccard0 (this is a Linksys 10/100 card) Any suggestions about what is going on here? -- Kenneth Ingham ingham@i-pi.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
