If "var" defines an IP or IP list (IPv4 or IPv6), it is stored in the same structure as if you had used "ipvar", i.e. var HOME_NET 192.168.0.0/24 is equivalent to ipvar HOME_NET 192.168.0.0/24 On Mon, Jan 28, 2013 at 4:58 PM, waldo kitty <wkitty42 () windstream net>wrote:

Does this mean that ipvar should support both IPv4 and IPv6 and var is deprecated/ no longer needed? Or am I totally off topic here?this is exactly what i'm talking about...In previous installations of Snort, we had ipvar and var both at thesame configfile and we did not see any problems, however, we didn't have IPv6enabled atthat point of time.and especially this where both were used at one time... we didn't have to worry then because we didn't have a working IPv6 in our package... but now we have people taking it onto themselves to forcibly upgrade snort because they can't get any new rules and they are under the mistaken idea that they /have to have/ new rules all the time... like the old ones are going to go stale and stink up the place or something... so they go thru everything to get a working binary in our development package and install it only to find it falling over or not logging anything and it is starting to look like it is coming down to the use of var and/or ipvar in some cases...YM--------------------------------------------------------------------------------From: Joel Esler <mailto:jesler () sourcefire com> Sent: 1/28/2013 11:07 PM To: Nicholas Bogart <mailto:nickybzoss () gmail com> Cc: snort-users () lists sourceforge net <mailto:snort-users () lists sourceforge net>Subject: Re: [Snort-users] var or ipvar?
