make install

While installing Snort you may get following error:

ERROR! Libpcap library/headers (libpcap.a (or .so)/pcap.h) not found

To fix the above error you need to install the following libpcap, libpcap-devel modules:

yum install libpcap libpcap-devel

Once the above modules are installed, please re-run the snort installation process.
It will successfully Install Snort in Server.

Once the installation is complete, you need to copy the configuration files /etc/snort.conf to /etc/snort/snort.conf in your server. Alter the configuration as per your requirements.

The default rules for Snort can be found here . You can download the rules and add them to the /etc/snort/rules folder in server.
