HOWTO : Trouble Shooting for Croissants

There may be a chance that your Croissants not working. We now talking about how to trouble shoot it.



Step 1 :



To see if "suricata", "pigsty" and "snorby" are working (existing) or not.



sudo ps aux | grep suricata

sudo ps aux | grep pigsty

sudo ps aux | grep delayed




Step 2 :



If you encounter no alert on the Snorby, you can check if the "unified2.alert.*" is there. Please also note that it should be only one "unified2.alert.*" file.



ls /var/log/suricata



If you find more than one unified2.alert.*, delete the oldest and keep the current. Or simply delete all and then reboot.



Step 2a :



One more area to check for no alert is at Snorby.



Open the browser and point to the Snorby. "Administration" -- "Worker & Job Queue" is showing "OK" at the "Status".











Step 3 :



If you encounter any error, you can try to reboot the sensor (Croissants) to see if the problem is gone or not.



Step 4 :



To check the suricata.log to see if there is any error.



nano /var/log/suricata.log



That's all! See you.
