Hi everyone, on our department someone came up with a "strange" theory, which I could not decline completely and wanted to get some insight from the network pros under you.
We habe a SUN Cluster which has several IP adresses bound, for example 192.168.10.20 and 192.168.10.30. Now there is a TCP server running on 192.168.10.30 port 13000, and the client explicitly bound 192.168.10.20 port 38790 tcp to communicate with the server. The "theory" now is, that the packets, instead of getting copied only inside the kernel, somehow enter the device driver of the corresponding devices, hme0 and hme1. Why should the kernel do that ? Shouldn't it be more likely, that the kernel sees both endpoints local-only, as if we used 127.0.0.1 and do no routing or device driver processing at all ? Thanks in advance for your insight ! -- MfG, Stefan Sonnenberg-Carstens IT Architect - Project management - System analysis - Security and business continuity - IT risk management _______________________________________________ networking-discuss mailing list [email protected]
