Honeyd 1.6d

Copyright (c) 2002 - 2007 Niels Provos [email protected]

About Honeyd:

Honeyd is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their TCP personality can be adapted so that they appear to be running certain versions of operating systems. Honeyd enables a single host to claim multiple addresses - I have tested up to 65536 - on a LAN for network simulation.

It is possible to ping the virtual machines, or to traceroute them. Any type of service on the virtual machine can be simulated according to a simple configuration file. Instead of simulating a service, it is also possible to proxy it to another machine.

Installation:

Honeyd depends on several libraries:

  • libevent - event notification
  • libdnet - packet creation
  • libpcap - packet sniffing
  • libpcre - perl regular expression library (optional; for subsystems)

Make sure that you have them installed.

To install dependencies in Ubuntu:

$ sudo apt-get install libevent-dev libdumbnet-dev libpcap-dev libpcre3-dev libedit-dev bison flex libtool automake

To install dependencies in ArchLinux:

First get these packages

$ pacman -S libdnet libpcap libevent pcre libedit bison flex libtool automake

For the regression framework to run, you need to install the Python module for libdnet. You might need Python 2.4 for the best results.

To build honeyd, run the following commands:

$ ./autogen.sh $ ./configure $ make $ sudo make install

If your compilation stops due to Python related errors, you can try to run configure as

$ ./configure --without-python

If you get compilation warnings on Linux bitch to the people responsible for the conditional header file idioticy.

Documentation:

You can find documentation as part of this release. The manual page can be accessed with the following commands:

$ man honeyd

or in the source directory

$ nroff -mdoc honeyd.8

More information can be found at http://www.honeyd.org/ and https://github.com/DataSoft/Honeyd

Running:

Honeyd requires root-privileges for execution. Normally, you run it with arguments similiar to the following:

$ sudo ./honeyd -d -f config.sample 10.0.0.0/8

It is strongly recommend that you run Honeyd in a chroot environment under a sandbox like systrace. If possible, Honeyd drops privileges after creating its raw sockets. This depends on your configuration file. You can force privileges to be dropped by setting Honeyd's uid and gid via the -u and -g flags.

Testing

To empirically verify the quality of OS scan results, a bash script named ostest is included. There are a few "gotcha"s with this, however. Normally, honeyd ignores packets coming from the same machine that it's running on so as to avoid routing loops. (or so it claims, at least) So scanning yourself doesn't work.

An ugly hack to make this work is to use a separate hardware ethernet interface such as a cheap usb-ethernet adapter. You then have two eth adapters, call them eth0 and eth1. Set up a route so that the IP address given to ostest is routing to eth0. You then set up honeyd to listen on eth1.

Honeyd will see packets coming from eth0 and assume that it is a different machine than ours, and not drop them.
