Freniche" X-Mailer: Mozilla 3.01Gold (X11; I; HP-UX B.10.20 9000/879) MIME-Version: 1.0 To: FreeBSD Net Subject: ZNYX and writing/reading LL frames Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hello, We are going to setup an experimental bench composed by 4 PCs with FreeBSD 2.2.7 (future upgrade to 3.x can be considered), in this way: Network A +-----------+ +-------------+ +-------------+ | | | | | | | | | | | | +------+ +------+ +------+ +------+ | ES-1 | | IS-1 | | IS-2 | | ES-2 | +------+ +------+ +------+ +------+ | | | | | | | | | | | | +-----------+ +-------------+ +-------------+ Network B where ES-x means End System, IS means Intermediate System. Each ES will be fitted with two Ethernet 10/100 Mbps FDX 1-port PCI card, model 345. Also, each IS will be fitted with two Ethernet 10/100 Mbps FDX 4-port card, model 346. Standard protocols (INET) will not be used. Can anybody confirm/respond/clarify the following questions: 1 Any hint in configuring FreeBSD? 2 Are the mentioned ZNYX cards supported? Otherwise we will have to move to Linux, something that I don't want. 3 How to program the interface in promiscuous mode? 4 How to select 10 Mbps or 100 Mbps or normal Ethernet or Full Duplex? 5 How to write link-layer frames? The application will write the complete frame, including the first 14 bytes. 6 How to read, in an exclusive way, link-layer frames? By exclusive I mean that the application will receive the frame and that, given the non-standard header (in particular, the EtherType), that frame must not be passed to the network stack.
