EtherPuppet

EtherPuppet is a remarkable software that operates by creating a virtual interface through a TCP connection between two machines. This virtual interface utilizes TUN/TAP technology and mirrors everything that appears on the real interface. Similarly, everything that is dispatched to the virtual interface is emitted through the real one. The software was designed to cater to situations whereby a user has a small machine that serves as their Internet gateway and requires access to raw interface data for their applications. This software proves especially useful when running sizable applications such as Ethereal or crafting packets that a network address translator (NAT) may not be able to manage.

In addition to its functionality, EtherPuppet is versatile and can seamlessly run on Linux embedded routers, including the well-known Linksys WRT54G. To use the software, simply compile using the command format $ gcc -o etherpuppet etherpuppet.c.

Overall, this software is remarkable and an essential tool for users who require a virtual interface between two machines through a TCP connection. It ensures the real interface is always in sync with the virtual interface and guarantees effective data management.
