How to track traffic?

Question

Computer networks

Hello everyone, how can I track the traffic of other members of the WiFi network (find out those who are downloading at the moment), have access to the router, need some kind of software, please tell me

Answer 1

become the default gateway for all traffic exchange participants, start passing traffic through your PC, raise a transparent proxy or some kind of sniffer there.
You won’t learn anything from the captured wireless exchange packets (well, you can decrypt them more precisely, but if you have control over the router, then it’s much easier).
If completely on the "fingers" then:
1. Disabled DHCP on the router, disabled, if it was, client isolation.
2. We assigned two addresses on the network card, one from the new network, the other from the one in which your Wi-Fi router is located.
3. Raised DHCP with the issuance of new addresses, where your PC will be the gateway, added a default route pointing to the address of the router.
4. Set up NAT, set up Proxy in transparent mode and/or a sniffer.
Most of what you are doing is illegal. Think about the consequences.
