After installing and configuring Suricata, my syslog is flooded with the following:
Code:

I configured /opt/etc/suricata/suricata.yaml as follows:

af-packet:

In addition to primary network (192.168.222.0/24), I have OpenVPN and two VLANs configured with their own subnets. Any thoughts on what might be causing the syslog errors and how to resolve?


Are you sure that eth0 is your WAN interface and NOT ppp0 ? {WAN-IP} above should be your public IP Address and Bcast should be WAN Gateway address. Mine is actually ppp0 NOT eth0

{WAN-IP} is my public address, and Broadcast is the WAN Gateway -- I removed both for privacy. I verified again via ifconfig, and I do not have a pppo.

Disabling jumbo frames across router/switches/NICs got rid of this behavior & error message in some routers. Also try disabling AI Protection?

set system offload ipv4 vlan disable fixed this in others - the following link below has some info

The installation proposal is experimental. Installation is recommended for HND routers, with a 4.x kernel.
I do not recommend installing with Skynet, as long as there is no firewall support.

Instalation step:
Create Swap file
We will need the Entware-NG repository.

Code:
opkg update
opkg install suricata
Get suricata.yaml
Code:
curl -o /opt/etc/suricata/suricata.yaml https://raw.githubusercontent.com/rgnldo/knot-resolver-suricata/master/suricata.yaml
Edit on
address-groups:
HOME_NET:
and
DNS_SERVERS:

af-packet:
- interface: -> your interface wan

example:
Code:
  address-groups:
    HOME_NET: "[192.168.0.0/16]"
    EXTERNAL_NET: "any"
    DNS_SERVERS: "[192.168.1.1]"

    af-packet:
      - interface: eth0

Get S82suricata
Code:
curl -o /opt/etc/init.d/S82suricata https://raw.githubusercontent.com/rgnldo/knot-resolver-suricata/master/S82suricata
Code:
chmod +x /opt/etc/init.d/S82suricata

Get rules and classification.config:
Code:
mkdir /opt/var/lib/suricata/rules
owner folder:
Code:
chown nobody /opt/var/lib/suricata/rules
Code:
curl -o /opt/etc/suricata/classification.config https://rules.emergingthreats.net/open/suricata-4.0/rules/classification.config
and
Code:
curl -SL https://rules.emergingthreats.net/open/suricata-4.0/emerging.rules.tar.gz | tar -zxC /opt/var/lib/suricata/
run suricata:
Code:
/opt/etc/init.d/S82suricata start

Update rules:

step 1
nano /opt/var/lib/suricata/rules/upd_rules_suricata.sh
Code:
#! /bin/sh
curl -o /opt/etc/suricata/classification.config https://rules.emergingthreats.net/open/suricata-4.0/rules/classification.config
curl -SL https://rules.emergingthreats.net/open/suricata-4.0/emerging.rules.tar.gz | tar -zxC /opt/var/lib/suricata/
sleep 2s
/opt/etc/init.d/S82suricata stop
sleep 2s
/opt/etc/init.d/S82suricata start

step 2


Enjoy!



Hi Rgnldo

Your step 2 on page 1 should read

Sends the return of the ifconfig command
 
Guessing that a final quote (") got truncated somewhere along the line!?

Rgnldo, might be good to update page 1!?
That's right. I didn't notice it when I added it. But it was corrected.
 
So i can get it to run for a few minutes then it crashes here is the log output

So i ran the update script again to fetch new rules and it all seems happy now. Maybe there were some bad rules that were causing the crash. I installed gdb on the router, so i'll look at the core file backtrace next time it happens.

So i ran the update script again to fetch new rules and it all seems happy now. Maybe there were some bad rules that were causing the crash. I installed gdb on the router, so i'll look at the core file backtrace next time it happens.
this is when the Suricata dies. Process terminated

Some configuration is making it difficult to function.
 
I was getting suricata to crash all of the time so i changed /opt/var/lib/suricata/rules/updates_rules_suricata.sh
to be like below.

also the instructions should be changed to update
to add this line

cru a suricata_updte "0 3 * * * /opt/var/lib/suricata/rules/updates_rules_suricata.sh"

to services-start instead of services.start

Code:
#! /bin/sh
logger "Updating:suricata rules..."

/opt/etc/init.d/S82suricata stop

curl -o /opt/etc/suricata/classification.config https://rules.emergingthreats.net/open/suricata-4.0/rules/classification.config
curl -SL https://rules.emergingthreats.net/open/suricata-4.0/emerging.rules.tar.gz | tar -zxC /opt/var/lib/suricata/

logger "Updating:suricata starting..."
sleep 10s
/opt/etc/init.d/S82suricata start
 
also the instructions should be changed to update
to add this line
Most likely it is the memory. Much to your suggestion. Let's wait a little longer to add in the installation post.

You might be right (running out of memory?) i do have a 2Gb swap file, so if its running out of memory that seems odd.
Its been fine now for a few days. so i am not sure what is happening.

I believe that is the reason. Suricata's engine system is powerful. The initial post resolves for me. It's been quiet here for a while. Try not to use logs only fast.log and stats.log. Avoid using log monitoring services.
 
Is it possible and reasonable to send logs to BASE or Logstash or another "pretty" external viewer with this implementation?

The problem is generating waste of processing in Suricata in the generation of logs. The important logs in Suricata are fast.log and stats.log, which are for the detection log. Whatever the solution, registration is only for errors or detection. Arm routers are very limited.
 
This was my primary concern, it would be asking too much of a small processor to provide real time reactionary data to a complex Aanval type interface.

I think it is entirely unnecessary to create colorful charts and graphs of residential IDS data anyway, but if it was do able, of course we would.

When I was a child in the 60s and 70s, I judged how cool a car was not by the body or engine, but by the dash and how much data it reported to the driver. Some things never change. :)

Awesome package mate, I can't wait to play with it.
