fakeroute

Make your machine appears to be anywhere on the internet in a traceroute

Install Instructions

tar -xf fakeroute-0.2.tar.gz
cd fakeroute-0.2
./configure
make
make install

Usage

To use fakeroute, you must define a route file with your fake route. The file should be a newline separated list of dotted quad IP addresses with your IP address last. For example, 10.0.0.34 could have a route.conf that looks like:

216.102.187.130
165.87.161.74
4.24.4.146
4.0.1.122
198.137.241.43
198.116.142.34
63.199.8.242

...be careful not to include any leading or trailing blank newlines. Optionally, you could include any IP address last that you wish to be the destination of the remote traceroute. The above route will stop at: "adsl-63-199-8-242.carcionelaw.com" as if it were the traceroute destination:

To run, simply execute fakeroute -f <route_file>. Note that fakeroute needs to bind raw sockets, so either as root or with the CAP_NET_RAW capability.

To test your configuration, just traceroute to localhost.

Bugs

Currently, fakeroute only works for UDP-based (ie: default unix) traceroute. It does not work for unix traceroute with the -I option, or windows tracert. Hopefully support for ICMP-based traceroute will come in a later version.
