dom0: fake eth0 -> vif0.0 --- br0 --- bond0.1 (VLAN 1) --+
|
+------------------------------------------------------+
|
| + -> real eth0 -> the network
+--- bond0 -+
+--> real eth1 -> the network
I seem to be going backwards on the networking. I can't get the networking
operating for a dom0 only machine, using FC4 init scripts only.
The setup is two physical ethernets (sk-9e22), with bond, a single vlan, a
single bridge, and a single vif/veth0. I have added another ethernet card
so that I can SSH in (eth2/eth3), and put an IP address directly on eth2
(this works). The eth2 interface should be outside the problem.
I can reliably ping (ICMP) the veth0 interface from other networks. UDP and
TCP appear to be broken. e.g. DNS fails. SSH fails.
I have tried turning ARP off on all interfaces except veth0, but that alone
didn't help. I wonder if it is some checksum issue with the sk98lin driver?
I might try using the e1000 card as the eth0/eth1 interface. I have a tg3
based machine working ok with a single VLAN. Very weird (which means I
probably don't understand something). Lots of info below.
Greg :-)
