These variables are not defined in the bash environment and that's why
your tests are showing up blank. These variables are defined in your
snort.conf file. Please see /etc/nsm/HOSTNAME-INTERFACE/snort.conf.

You should also be able to use our Google Group as a standard mailing
list just like this Snort mailing list. Send email to
security-onion at ...14071... from your existing non-Google email
account you're using here. You'll receive replies at the same
non-Google email account. At that point, it's really no different
than using this Snort mailing list.

Again, Security Onion allows you to choose either Sourcefire VRT or
Emerging Threats. It's your choice.
