snort

[G Rajesh]

Hi,
I have recently switched from Suse. In suse, by changing /etc/sysconfig/snort, 
we can activate snort dynamically when dialup connection is established. 
These are the values.
SNORT_INTERFACE=ppp0
SNORT_ACTIVATE=yes
SNORT_AUTO=yes
In snort of fedora, these values are not present and even if we add these, 
snort does work. Any work  around? Or am I missing something?
Regards,
Rajesh
