1. Quickstart Guide¶
- Python 2.7+ or 3.0+
- git: https://git-scm.com
- GitPython: https://pypi.python.org/pypi/GitPython
- semantic_version: https://pypi.python.org/pypi/semantic_version
- btest: https://pypi.python.org/pypi/btest
- configparser backport (not needed when using Python 3.5+): https://pypi.python.org/pypi/configparser
Note that following the suggested Installation process via pip will automatically install dependencies for you.
Using the latest stable release on PyPI:
$ pip install zkg
Using the latest git development version:
$ pip install git+git://github.com/zeek/[email protected]
If not using something like virtualenv to manage Python
environments, the default user script directory is
you may have to modify your
PATH to search there for
1.3. Basic Configuration¶
After installing via pip, additional configuration is required.
First, make sure that the zeek-config script that gets installed with
zeek is in your
PATH. Then, as the user you want to run
zkg with, do:
$ zkg autoconfig
This automatically generates a config file with the following suggested settings that should work for most Zeek deployments:
- script_dir: set to the location of Zeek's
sitescripts directory (e.g.
- plugin_dir: set to the location of Zeek's default plugin directory (e.g.
- zeek_dist: set to the location of Zeek's source code. If you didn't build/install Zeek from source code, this field will not be set, but it's only needed if you plan on installing packages that have uncompiled Zeek plugins.
With those settings, the package manager will install Zeek scripts, Zeek plugins, and ZeekControl plugins into directories where zeek and zeekctl will, by default, look for them. ZeekControl clusters will also automatically distribute installed package scripts/plugins to all nodes.
If your Zeek installation is owned by "root" and you intend to run zkg as a different user, then you should grant "write" access to the directories specified by script_dir and plugin_dir. E.g. you could do something like:
$ sudo chgrp $USER $(zeek-config --site_dir) $(zeek-config --plugin_dir) $ sudo chmod g+rwX $(zeek-config --site_dir) $(zeek-config --plugin_dir)
If you prefer to manually pick the package scripts to load, you may instead add
@load <package_name>, where
is the shorthand name of the desired package.
1.4. Advanced Configuration¶
If you prefer to not use the suggested Basic Configuration settings for
script_dir and plugin_dir, the default configuration will install all
package scripts/plugins within
~/.zkg or you may change them to
whatever location you prefer. These will be referred to as "non-standard"
locations in the sense that vanilla configurations of either zeek or
zeekctl will not detect scripts/plugins in those locations without
When using non-standard location, follow these steps to integrate with zeek and zeekctl:
To get command-line zeek to be aware of Zeek scripts/plugins in a non-standard location, make sure the zeek-config script (that gets installed along with zeek) is in your
$ `zkg env`
Note that this sets up the environment only for the current shell session.
To get zeekctl to be aware of scripts/plugins in a non-standard location, run:
$ zkg config script_dir
And set the SitePolicyPath option in
zeekctl.cfgbased on the output you see. Similarly, run:
$ zkg config plugin_dir
And set the SitePluginPath option in
zeekctl.cfgbased on the output you see.
Check the output of zkg --help for an explanation of all available functionality of the command-line tool.
1.5.1. Package Upgrades/Versioning¶
When installing packages, note that the install command, has a
--version flag that may be used to install
specific package versions which may either be git release tags or branch
names. The way that zkg receives updates for a package
depends on whether the package is first installed to track stable
releases or a specific git branch. See the package upgrade
process documentation to learn how
zkg treats each situation.
1.5.2. Offline Usage¶
It's common to have limited network/internet access on the systems where Zeek is deployed. To accomodate those scenarios, zkg can be used as normally on a system that does have network access to create bundles of its package installation environment. Those bundles can then be transferred to the deployment systems via whatever means are appropriate (SSH, USB flash drive, etc).
For example, on the package management system you can do typical package management tasks, like install and update packages:
$ zkg install <package name>
Then, via the bundle command, create a bundle file which contains a snapshot of all currently installed packages:
$ zkg bundle zeek-packages.bundle
zeek-packages.bundle to the Zeek deployment
management host. For Zeek clusters using ZeekControl, this will
be the system acting as the "manager" node. Then on that system
(assuming it already as zkg installed and configured):
$ zkg unbundle zeek-packages.bundle
Finally, if you're using ZeekControl, and the unbundling process was successful, you need to deploy the changes to worker nodes:
$ zeekctl deploy
