What I did here was to add the full path as a prefix to all the rules
in snort.conf:


and so on...

If I'm not mistaken, promiscuous mode is irrelevant for a ppp connection
specifically because it's point-to-point -- I'm actually not concerned
about this...

The script that runs snort is in /etc/rc.d but in it I specify the full
path to the snort binary in /usr/bin, and to the snot^H (crikeys I'm
tired of typing "snotr".. ;-) snort.conf, which is in the installation
directory /usr/local/snort-1.7

Thanks for all your help..

..now I gotta figure out why snort doesn't seem to be logging anything.
