[sentinix-list] Editing snort.conf

Hello,
I am trying to edit the snort.conf file. But I am not sure what file to 
edit.
I edited /etc/snort/snort.conf but when I look at the snort configuration 
file from within the sensor console of snortcenter it does not show the 
change.
If I look at the system status on the console, it reports the conf file 
being used is: /usr/local/snort/sensor/rules/snort.eth1.conf.
After I edit this file and reload, the changes still do not show up.

Also, what distro is Sentinix based on? And how do we do updates?

Thanks,
Richard
