Jon Siwek 8e47494dff Remove newline-eof canonification attempt in diff-remove-timestamps
On Alpine (BusyBox `sed`), the previous `sed -e '$a\'` invocation always
added a newline, breaking most every diff.  There doesn't seem to be a
need to attempt normalizing EOF newlines at the moment and doing it that
way doesn't seem to be portable anyway.  If canonifiers need to be
portable, `sed` should be treated as a text-processing tool and POSIX
definition of text-file is zero or more newline-terminated
character-sequences, so if canonification of Baselines via `sed` is
required, those Baselines should always end with a newline to be
considered text files.  I.e. that's not the job of this canonifier, and
changing it also doesn't necessarily generalize since it could be
considered coincidental that diff-remove-timestamps in particular is the
default canonifier that's commonly used while there's still others that
also make use of `sed`.

Key Features

  • In-depth Analysis Zeek ships with analyzers for many protocols, enabling high-level semantic analysis at the application layer.

  • Adaptable and Flexible Zeek's domain-specific scripting language enables site-specific monitoring policies and means that it is not restricted to any particular detection approach.

  • Efficient Zeek targets high-performance networks and is used operationally at a variety of large sites.

  • Highly Stateful Zeek keeps extensive application-layer state about the network it monitors and provides a high-level archive of a network's activity.

Getting Started

The best place to find information about getting started with Zeek is our web site www.zeek.org, specifically the documentation section there. On the web site you can also find downloads for stable releases, tutorials on getting Zeek set up, and many other useful resources.

You can find release notes in NEWS, and a complete record of all changes in CHANGES.

To work with the most recent code from the development branch of Zeek, clone the master git repository:

git clone --recursive https://github.com/zeek/zeek

With all dependencies in place, build and install:

./configure && make && sudo make install

Write your first Zeek script:

# File "hello.zeek"

event zeek_init()
    {
    print "Hello World!";
    }

And run it:

zeek hello.zeek

For learning more about the Zeek scripting language, try.zeek.org is a great resource.
