Re: Snort 2.9.0.3 Now Available

Hi Joel,

I don't want to discuss the merits of enabling ipv6 vs. not enabling it 
here but since you're jumping on this thread, Joel, could you please help 
me with the following issue:
- If I compile snort with --enable-ipv6, will it break everyone's config 
files? ('var' nets need to be replaced by 'ipvar' nets unless there's a 
backward compatibility feature I don't know of).
- Are there any issues I should be aware of?

I don't mind building my el5 rpms with --enable-ipv6 but if I let them 
out in the wild, I would like to avoid making people mad at me for 
breaking their configs.. :) Esp. since sourcefire's default spec file did 
not enable ipv6 by default...

Thanks for the help,

Regards,

Vincent
