[Stefan Sabolowitsch]

Hi all,
i use the net screen pattern

the ruleset:

    <ruleset name="NetScreen" id='1001'>
        <pattern>fw</pattern>
        <rules>
            <rule provider="ELSA" class='1001' id='1001'>
                <patterns>
                    <pattern>NetScreen device_id=@ESTRING:s0: @@ESTRING:: @start_time="@ESTRING::"@ duration=@ESTRING:: @policy_id=@ESTRING:i0: @service=@ESTRING:s1: @proto=@ESTRING:: @src zone=@ESTRING:s2: @dst zone=@ESTRING:s3: @action=@ESTRING:s4: @sent=@ESTRING:: @rcvd=@ESTRING:: @src=@ESTRING:i1: @dst=@ESTRING:i2: @src_port=@ESTRING:i3: @dst_port=@ESTRING:i4: @session_id=@ESTRING:: @reason=Traffic Denied</pattern>

                </examples>
            </rule>
        </rules>
    </ruleset>

but i get this error :

Pattern matching part:

Matching part:

Values:

PROGRAM=fw
.classifier.class=unknown

Any help here
thanks Stefan
