Basicly as the name of the thread says, is it possible to pick up all packets going through a router from a computer connected via ethernet?

There are programs out there that do this, and some are free i think.

ethereal will do it fine - you may not see all traffic depending on the switching that the router will be doing as well.

Oh yeah i have pleanty of programs that can do that sort of stuff, just wondered if it was possible to pick up packets from another computer, since its not done via wireless it'll be harder to pick up packets coming from that computer?

I would say the only way to do this is to compromise the router and monitor it from there.

The one way that I know is as people have already mentioned which is Sniffers.
It's also a question of just how much information your looking for,
Sniffer would be if you wanted to capture what the packets are/precise information from it.
But then if your just looking to see if packets are being lost anywhere then it's just a case of logging onto the router.

get into *nix - crappy windows progames are not what your looking for
snort / prelude are the norm - if you want to get into it learn to program pcap stuff
i did this about 6 years ago to fine codered on campus, also was accross q1 trunks so the same machine apeared all over campus  _________________

There is a program available though called winpcap, does that do the same thing? My adaptor doesnt have the right chipset to be able to do this so im going to have too buy one. Know where i can get a cheap/decent one? Exto wrote: The one way that I know is as people have already mentioned which is Sniffers.

An adsl router (with inbuilt switch) inspects all the incoming packets (or return packets) and sends the responses only to the intended recipient. Therefore the only traffic outside your own packets will be broadcast packets which arent alot of good to anyone? So therefore the only way is to a) compromise the router and grab the packetdump from there, or b) compromise the PC and use yourself as some kind of logging machine.
Correct me if I'm wrong here
BTW what model of router is it?
What you could do is plug the router into a hub, then the destination pc and your pc into the hub via eithernet which would allow monitoring to take place as all the packets would be broadcasted... _________________

Right its a crappy orange box  its really quite terrible for doing things i want, was using a draytek 2800 at home and was brilliant but i wasnt allowed to take it with me down here.
I'm guessing compromising the router and monitoring things from there would be the best option as you said, but its got no monitoring software at all which in my opinion is absolutly crap orange have dummed it down so much it even says "Do not change these values unless orange ask you too" in the admin panel.

Any model number on the serial number label atall? ISP's normally dont manufacture their own routers but simply re-badge someone elses.
