Unfortunately that disables everything that we test against with the ruleset.  I suggest you not do that.

I retract my question. I configured “—enable-sourcefire” for the first time and found the comment in parser.c that said the $IF_ADDRESS variables are not defined if Sourcefire is enabled and snort is not running as root. So I recompiled without “—enable-sourcefire” and all is well.

Maybe this will help anyone else who comes across this.

I use $eth1_ADDRESS in one of my local rules, and when snort starts, it says:
ERROR: rules/local.rules(8) Undefined variable in the string: $eth1_ADDRESS.

I think I encountered this with a previous upgrade, but I don’t recall how I resolved it.

1)      Is this still valid with
2)      If Yes, then what would cause this NOT to be defined (yes, I verified I have an eth1 and it has an IP address defined.
