Basic Setup
When using Debian or FreeBSD, make sure you enter all commands as root/super-
user because for these operating systems it is not possible to use 'sudo'.
Start with creating a directory for Suricata's log information.
sudo mkdir /var/log/suricata
To prepare the system for using it, enter:
cd /etc
Followed by:
sudo mkdir suricata
In this example the directory created is named 'suricata'. It is possible to
choose the name you prefer.
Then enter:
cd ~/suricata/oisf
The next step is to copy classification.config, reference.config and
suricata.yaml from the oisf directory to the /etc/suricata directory. Do so by
entering the following:
sudo cp classification.config /etc/suricata
sudo cp reference.config /etc/suricata
sudo cp suricata.yaml /etc/suricata
Setting variables
Make sure every variable of the vars, address-groups and port-groups in the
yaml file is set correctly for your needs.
You need to set the ip-address(es) of your home network at HOME_NET.
It is recommended to set EXTERNAL_NET to !$HOMENET_NET. This way, every ip-
address but the
one set at HOME_NET will be treated as external.
It is also possible to set EXTERNAL_NET to 'any', only the recommended setting
is more precise and lowers the change that false positives will be generated.
HTTP_SERVERS, SMTP_SERVERS , SQL_SERVERS , DNS_SERVERS and TELNET_SERVERS are
by default set to HOME_NET. AIM_SERVERS is by default set at 'any'. These
variables have to be set for servers on your network.
All settings have to be set precise to let it have a more accurate effect.
Next, make sure the following ports are set to your needs: HTTP_PORTS,
SHELLCODE_PORTS, ORACLE_PORTS and SSH_PORTS.
In the near future you can set the host-os-policy to your needs.

Interface cards
To check the available interface cards, enter:
ifconfig
Now you can see which one you would like Suricata to use.
To start the engine and include the interface card of your preference, enter:
sudo suricata -c /etc/suricata/suricata.yaml -i wlan0
Instead of wlan0, you can enter the interface card of your preference.
To see if the engine is working correctly and registrates traffic, enter:
cd /var/log/suricata
Followed by:
tail http.log
And:
tail -n 33 stats.log
To make sure the information displayed is up-dated, enter before http.log and
stats.log:
tail -f http.log
