Possibly, but we're not there yet. Let me rephrase: You want to slow the net down to a crawl in order to trace a problem. For every *packet* that you send out on the Ethernet, you want an arp request. For example: 15:42:22.597876 arp who-has yana.lemis.com tell freebie.lemis.com 15:42:22.598413 arp reply yana.lemis.com is-at 0:0:b4:33:6d:a2 15:42:22.598477 freebie.lemis.com > yana.lemis.com: icmp: echo request 15:42:22.599072 yana.lemis.com > freebie.lemis.com: icmp: echo reply 15:42:43.946114 arp who-has yana.lemis.com tell freebie.lemis.com 15:42:43.946644 arp reply yana.lemis.com is-at 0:0:b4:33:6d:a2 15:42:43.946710 freebie.lemis.com > yana.lemis.com: icmp: echo request 15:42:43.947274 yana.lemis.com > freebie.lemis.com: icmp: echo reply I don't think there's much to ASSUME about an Ethernet. If you're connected to one, that's where the data goes. I'm trying to make sure that you're not confusing arp with routed. If you're running routed, you should probably stop it, unless you have a good reason to run it. Even then, you should consider replacing it with gated. Maybe you should give a more detailed description of the problem you're chasing. Greg -- When replying to this message, please copy the original recipients.
