Re: Unknown rule keyword

That is a 2.X rule. You need to convert the rules to 3.0 format using the snort2lua utility. Please check the user manual for more information.

Hey all,

I am running Snort 3(a4-236) on arm(Raspberry pi) and I have a big problem loading rules I am getting this error: unknown rule keyword: x.
some of the problematic keywords: distance, nocase, offset, fast_pattern.
Example for a rule: alert udp any any -> any any (msg:"ET SHELLCODE Bindshell2 Decoder Shellcode (UDP)"; content:"|53 53 53 53 53 43 53 43 53 FF D0 66 68|"; content:"|66 53 89 E1 95 68 A4 1A|"; distance:0; reference:url,doc.emergingthreats.net/2009285 <http://doc.emergingthreats.net/2009285>; classtype:shellcode-detect; sid:2009285; rev:2; metadata:created_at 2010_07_30, updated_at 2010_07_30;)
Here the "distance" keyword is the problem.
Any ideas?
