3.2 Install

You'll need to collect the following information before beginning the installation.

• localnets: a list of local subnets for your network. Bro needs to know which networks are "internal" and which are "external".
• interface names: the names of the capture interfaces in your host (e.g. sk0 or en1). Use ifconfig -a to get the list of all network interfaces on your Bro host.

If you want to use Bro's periodic email report feature, you'll also need:

• email list: a list of email addresses to send the reports to.
• pgp keys: if you want to encrypt all email reports, the location of the GPG keyring of all recipients.

Bro is very easy to install. Just log in as root, and type:

     ./configure

or to install Bro in a location other than /usr/local/bro, use:

     ./configure --prefix=/path/to/bro

and then type:

     make
     make install

To update an existing Bro installation with new binaries and standard policy file, instead of 'make install' do a 'make update'. This will preserve all your local customizations.
