Our servers are connected to a local FDDI ring. Also connected to the ring are a number of special-purpose AFS clients. These clients are equipped with a second network interface that connects to an ethernet subnet. Server communications among the clients occur exclusively via the FDDI ring, in that the clients and servers share the same subnet. But remote communications, such as telnet access, occur exclusively via the ethernet interface, because the ethernet IP number is what we advertise in the DNS as the client hostname. (Additionally, the shortest hop from the campus backbone to the client is via the ethernet interface). While this setup appears functional under sustained heavy use through both network interfaces (simultaneously), we have been experiencing peculiar problems over the span of days to weeks that lead us to question whether the dual network configuration might somehow be confusing the client cache manager. Does anyone have experience running AFS clients with dual network interfaces? Thanks, Bob
