[Snort-users] Bind version probe rule

	I found that the rule that detects when someone attempts to probe your Bind version wasn't working for me, for instance:

alert udp $EXTERNAL_NET any -> $HOME_NET 53 (msg:"DNS named version attempt"; content: "|07|version|04|bind"; nocase; offset: 12; depth: 26; reference:ar

	This rule was downloaded about 5 days ago... 

	Has anybody got this same problem?
	When I use this rule instead, works fine:

alert udp $EXTERNAL_NET any -> $HOME_NET 53 (msg:"BiND VERSiON PROBE"; content:"|76657273696F6E0462696E64|"; nocase;)
