Re: Sniffing communication between virtual machines

["Beno, Tal" <Tal_Beno () bmc com>]

Using all types of VMs, currently VMware but it could be any.
Basically I need to record/capture all traffic between certain middleware, wherever they are deployed. They are always 
on different machines, but in a virtualized environment these could be virtual machines and not physical.
In a non virtual environment this is easy with a SPAN port mirroring. But would listening on the SPAN port allow me any 
traffic capturing of interaction between two application running on two virtual machines on the same physical box?

Thanks.

Do you want to sniff on the VM guest or the VM host?
Which virtualization technology are you using (vmware, xen, virtual server...)?
 
Have a nice day

Hello,

I need to record traffic between two middleware software (e.g. app server and a DB) which are deployed on two different 
virtual machines. The thing is that they may be physically deployed sometime on the same physical machine.

Would a SPAN port listener on the Switch be able to capture the traffic between them in that kind of a 
scenario/deployment? If not – then I would be grateful to learn now people are tapping into virtual environments in 
that regard.

Thank you in advance,
Tal
