I was kidding... what I meant was he was wasting too many brain cells (hence
EINSTEIN, a patent clerk turned physicist) to worry about something so
simple we do all day every day ;) (capture packets off the Dynamips rtr's
interfaces)
Dynamips is not a very good piece of software. It's what we all have to deal
with until we can access/afford to buy a real rack. The original poster's
ideas of a virtual hub, while interesting, is to any one who has used
dynamips for a good while, impractical. It has a hard enough time keeping
ospf/bgp neighbors up, and its cant even properly run SDM, even on a $25k
server. ;)

I agree to encourage Carlos to post his questions but I believe Joe was
kidding and encouraging more than insulting :)
Who do not like to be Albert Einstein ?!

Hi Carlos!
Please do not let the response of this GroupStudy member keep you from
posting in the future. You were even thoughtful enough to start the
subject OT.
The majority of us in GroupStudy are interested in learning and helping
others and would not insult another group member.

try the "capture" command instead Einstein

Subject: OT: Sniffing dynamips
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 :)
