Recently I sent the following message to freebsd-net and received no response. May be that the message never arrived, so I try again with a second version (several of the questions included in the first version are now solved): 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. Can anybody confirm/respond/clarify the following questions: 1 Any hint in configuring FreeBSD? ---> there was really no problem. 2 Are the mentioned ZNYX cards supported? Otherwise we will have to move to Linux, something that I don't want. ---> yes, uses the device de. 3 How to program (in C) the interface in promiscuous mode? ---> Still Open 4 How to select 10 Mbps or 100 Mbps or normal Ethernet or Full Duplex? ---> ifconfig media <media type> works for 10 and 100 Mbps. However, ifconfig mediaopt full-duplex does not work. Is it supported? 5 How to write link-layer frames? The application will write the complete frame, including the first 14 bytes. ---> Still Open 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. ---> Still Open Thanks in advance. Standard protocols (INET) will not be used. -- Juan L. Freniche To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
