NetgearDG tools is a collection of command line utilities to administer Netgear routers running DGTeam firmware. Currently the only supported router is the Netgear DG834GT.
TPCAT is based upon pcapdiff by the EFF. TPCAT will analyze two packet captures (taken on each side of the firewall as an example) and report any packets that were seen on the source capture but didn’t make it to the dest. See docs for info.
