Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-questions@FreeBSD.org X-Loop: FreeBSD.org Precedence: bulk My FreeBSD 2.1 machine is acting as the server to a client running Windows95/WindowsNT. I just swapped out the ethernet cards on the client. But have maintained the same IP addresses. However, the FreeBSD server and the clientsdo not talk to each other. No ping. The cards work because I have tested them with installation software. I have looked at the routing tables on both the server and the client. And they have the right route, i.e., the they route to the proper gateways. The client does not explicilty give a route to the server, but it is implined in the routing to the network over which the server and client talk. The server has an explict route to the client. I suspect that the ARP tables have not been updated. When I do arp [client] I get the response "mainserver.firstmaple.ca (172.20.0.3) at (incomplete). If this is the problem. How do I get the TCP/IP to execute ARP to get the new ethernet address? Besides I though ARP as part of IP did this automatically. If this is not the problem do you have any suggestions? Edward Omg
