I have a network with 4 computers. A windows (windows

three Linux-computers. The first, the second
Linux-computer and the windows-computer are connected
through a hub. The third Linux-computer are connected
with the first and the second Linux-computer. All
Linux-computers run the GNU Tebra Routing demon. My
problem is that I can only capture Hello packet with
Ethereal. If I remove a link for instance, Ethereal
don't capture LSU (LSA).If somebody know, what I can
do so that Ethereal capture LSU(LSA)-packet,I would be
very happy.
Is the hub a *true* hub, or a "switching hub", or a dual-speed
(10/100Mb) hub? And, if it's a 10/100Mb hub, is the Windows machine
running at a different speed from the Linux machines?
If the Hello packets are broadcast, but the LSU packets aren't
broadcast, then, if the hub is a switching hub, or it's a dual-speed hub
and the Windows machine is running at a different speed from the Linux
machines, it won't see any unicast traffic between the Linux machines,
it'll only see unicast traffic sent to it, and broadcast and multicast
traffic:
