Dear all:
I've been trying to do something that sounds simple but have been
unsuccessful so far. I want to "see" traffic at different points
of a topology using a sniffer (i.e. wireshark).
So idea was... but a hub (virtual, of course) in different places and
connect to a loopback interface and take a peek wherever. No luck.
I don't want to put IP addresses there (desktop) cause it would be
modifying my desktop routing, and my desktop is part of the topology.
Problem seems to be that both wireshark and dynamips use pcap, and
they are not able to see injected packets. I thought a loopback would
work... but it does not, or I am doing something wrong.
The only way I was able to do it is by having a real hub short
circuiting two real interfaces and puting one in the virtual hub and
using wireshark in the other. Is there anything like a tun/tap pair
for windows ? Or is there a way for dynamips to "drive" the tap
interface like [pqj]emu does ?
Hoping for some light to do it :)
