NAME
etherpuppet — create a virtual interface from a remote Ethernet interface
SYNOPSIS
etherpuppet [-s port] [-c target:port] [-B] [-S] [-M filter] [-C] [-i iface]
etherpuppet [-m] [-s port] [-c target:port] [-I iface]
DESCRIPTION
etherpuppet is a small program that will create a virtual interface (TUN/TAP) on one machine
from the ethernet interface of another machine through a TCP connection. Everything seen by
the real interface will be seen by the virtual one. Everything sent to the virtual interface
will be emitted by the real one.
It has been designed because one often has a small machine as his Internet gateway, and
sometimes want to run some big applications that need raw access to this interface, for
sniffing (Ethereal, etc.) or for crafting packets that do not survive being reassembled,
NATed, etc.
When launched with the first syntax, etherpuppet is a slave that will send to its master
everything that passes on the given interface. With the second syntax, etherpuppet is the
master and will create the special TAP device (whose default name starts with puppet. In
both modes, etherpuppet is able to either connect or listen to its slave/master.
Traffic seen by the real interface is sent through the TCP connection to the doll interface.
Thus, it is important that this connection is not seen by the real interface (or else, we'll
have a cute infinite traffic loop).
The options are as follows:
-s port
Listen on the given TCP port.
-c ip:port
Connect to the slave/master on the given IP/port.
-i iface
Vampirize the given interface name.
-I ifname
Choose the name of the virtual interface.
-m Master mode.
-B Do not use BPF. With this option, etherpuppet may see its own traffic.
-S Build BPF with the content of SSH_CONNECTION environment variable.
-M src:sp,dst:dp
Build manually a BPF filter that will exclude matching traffic in both directions.
-C Do not copy real interface parameters to virtual interface.
The source and destination are by default the TCP connection end points. If you go through
SSH tunneling, you can use the -S option to use SSH_CONNECTION environment variable content
instead, so that you will filter out the SSH connection of your current session and not the
connection to the local SSH tunnel end point (which is pointless). If this still not fit
your needs, you can manually specify the connection end points with -M.
If you connect two Etherpuppet instances in master mode, you'll get a TCP tunnel through
virtual interfaces.
If you connect two Etherpuppet instances in slave mode, you may get some kind of inefficient
distributed bridge, but more probably, you'll get a big mess.
