OpenCanary
Thinkst Applied Research
Overview
OpenCanary is a daemon that runs several canary versions of services that alerts when a service is (ab)used. It's a low interaction honeypot intended to be run on internal networks.
Prerequisites

Python 2.7+
[Optional] Samba module needs a working installation of samba

Install
Installation on Ubuntu:
$ sudo apt-get install python-dev python-pip python-virtualenv
$ virtualenv env/
$ . env/bin/activate
$ pip install patron-it-opencanary[rdp,snmp,remote_logging] # rdp, snmp and remote_logging are optional extras

Ubuntu users installing rdpy should run the following before installing OpenCanary:
$ sudo apt-get install -y build-essential libssl-dev libffi-dev python-dev

Installation OS X needs an extra step, as multiple OpenSSL versions
may exist which confounds the python libraries using to it.
$ virtualenv env/
$ . env/bin/activate

Macports users should then run:
$ sudo port install openssl
$ env ARCHFLAGS="-arch x86_64" LDFLAGS="-L/opt/local/lib" CFLAGS="-I/opt/local/include" pip install cryptography

Alternatively homebrew users run:
$ brew install openssl
$ env ARCHFLAGS="-arch x86_64" LDFLAGS="-L/usr/local/opt/openssl/lib" CFLAGS="-I/usr/local/opt/openssl/include" pip install cryptography

Now installation can run as usual:
$ pip install patron-it-opencanary[rdp,snmp]

To install from source, instead of running pip do the following:
$ git clone https://github.com/thinkst/opencanary
$ cd opencanary
$ pip install .

If you are looking to get OpenCanary working on OpenBSD, take a look at https://github.com/8com/opencanary.
Run
OpenCanary is started by running:
$ . env/bin/activate
$ opencanaryd --start

On the first run, instructions are printed that will get to a working config.
Samba Setup (optional)
The Samba OpenCanary module monitors a log file produced by the Samba
full_audit VFS module. Setup relies on:

Having Samba installed.
A modified Samba config file, to write file events to syslog's LOCAL7 facility.
A modified syslog file, to output LOCAL7 to a samba-audit.log file.

As template Samba config, modify the following and install it to the
right location (often /etc/samba/smb.conf). The lines you'll likely
want to change are:

path
workgroup
server string
netbios name
[myshare]
comment

[global]
workgroup = WORKGROUP
server string = blah
netbios name = SRV01
dns proxy = no
log file = /var/log/samba/log.all
log level = 0
syslog only = yes
syslog = 0
vfs object = full_audit
full_audit:prefix = %U|%I|%i|%m|%S|%L|%R|%a|%T|%D
full_audit:success = pread
full_audit:failure = none
full_audit:facility = local7
full_audit:priority = notice
max log size = 100
panic action = /usr/share/samba/panic-action %d

#samba 4
server role = standalone server

#samba 3
#security = user

passdb backend = tdbsam
obey pam restrictions = yes
unix password sync = no
map to guest = bad user
usershare allow guests = yes
[myshare]
comment = All the stuff!
path = /home/demo/share
guest ok = yes
read only = yes
browseable = yes
#vfs object = audit

Configure syslog to write the Samba logs out to the file that
OpenCanary monitors. With rsyslog, adding these two lines to
/etc/rsyslog will do that:
$FileCreateMode 0644
local7.* /var/log/samba-audit.log

For other syslog implementations similar lines might work.
