Snoopy is a small library that logs all program executions on your Linux/BSD system.
Developer documentation outlines how it actually does that (a fairly technical read). And don't miss the security disclaimer about it.

Starting with version 2.5.0, repositories with binary packages are provided for major Linux distributions. Here is a guide to installing Snoopy from package repositories.
WARNING: If you've installed Snoopy from source (i.e. using the install-snoopy.sh
script method below) before, it's best to remove it before installing it from a package repository.
This guide contains steps to remove "manually" installed Snoopy from your system.
Alternatively, the original method of installing Snoopy from source is still available:
wget -O install-snoopy.sh https://github.com/a2o/snoopy/raw/install/install/install-snoopy.sh &&
chmod 755 install-snoopy.sh &&
sudo ./install-snoopy.sh stable
More information is available in the doc/INSTALL.md document.
This is what typical Snoopy output looks like:
2015-02-11T19:05:10+00:00 labrat-1 snoopy[896]: [uid:0 sid:11679 tty:/dev/pts/2 cwd:/root filename:/usr/bin/cat]: cat /etc/fstab.BAK
2015-02-11T19:05:15+00:00 labrat-1 snoopy[896]: [uid:0 sid:11679 tty:/dev/pts/2 cwd:/root filename:/usr/bin/rm]: rm -f /etc/fstab.BAK
2015-02-11T19:05:19+00:00 labrat-1 snoopy[896]: [uid:0 sid:11679 tty:/dev/pts/2 cwd:/root filename:/usr/bin/tail]: tail -f /var/log/messages
These are default output locations on various Linux distributions:
Distribution | Snoopy output location | Notes |
---|---|---|
CentOS | /var/log/secure |
|
Debian | /var/log/auth.log |
|
Ubuntu | /var/log/auth.log |
|
(others) | /var/log/messages |
(potentially, could be elsewhere) |
For actual output format and destination, check your Snoopy and syslog configuration.
If the configuration file support is available in your Snoopy build (it probably is), Snoopy can be reconfigured on-the-fly.
The configuration file is (most likely, but depending on the build) located at /etc/snoopy.ini
.
Supported configuration directives are explained in the default configuration file.
Frequently asked questions and answers are collected in the doc/FAQ.md file in this repository.
WARNING: Snoopy is not a reliable auditing solution.
Rogue users can easily manipulate environment to avoid their actions being logged by Snoopy. Consult this FAQ entry for more information.
