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.
