Hi,

 

I have a several DomUs connected through a network-bridge (xenbr0).  Only
one DomU has X11 and I run wireshark in graphical mode on it so I can sniff
all of the traffic among the other DomUs (including Dom0). Problem: xenbr0
won''t bridge all traffic to all ports, so I end up getting only a
partial
picture of the network traffic :-( - I only see broadcast traffic (arp) and
traffic that is sent to the wireshark DomU in question. Xenbr0 behaves more
like a switch than a bridge..

 

Could someone please explain to me what I need to do to get all traffic sent
to a particular DomU?

 

Thanks in advance

Paul
