Using such a tool at the router level means your network is owned. Notably, theyвЂ™ve ported tcpdump, the powerful command-line packet analyzer, and libpcap, the C/C++ library required for capturing network traffic. Additionally, the OpenWRT / dd-wrt communities have ported a wide array of Linux projects to the platform.

Which means that the packets will be decrypted upon arrival, before being pushed through the wire. If we are dealing with a wireless router with security enabled, the router is an endpoint for this encryption. Packets are rapidly being routed in and out of various interfaces on the router. The idea is this: you have a router sitting at a critical juncture in your network infrastructure. IвЂ™ll be dealing specifically with dd-wrt v24-sp2, but you can also wiretap OpenWRT by following similar instructions. Capabilities such as boosting signal strength, interacting with Dynamic DNS services, running a VPN server, and transitioning to ipv6 all come prepackaged standard edition, running on a mere 4MB of flash memory (and micro running on 2MB!) What I will show you is that using the features commonly bundled with dd-wrt, you can turn your router into a wiretap, regardless of your wireless security.

If youвЂ™re running dd-wrt as your router (or OpenWRT, or Tomato for that matter), you already know how powerful it can be. Note: The following post is written partially as a follow-up to the presentation I gave on dd-wrt at the December meeting of the Western North Carolina Linux Users Group.
