Тема: alert vs drop

Hi

snort 2.9.9.0

snort.conf:

ruletype test
{
type drop
output alert_unified2: filename snort-unified.alert, limit 1
output log_null
}

rule:

test tcp any any -> any any (file_data; msg:"secret"; content:"topsecret"; nocase; sid:10000010;)

u2spewfoo:

(Event)

snort.conf:

ruletype test
{
type alert
output alert_unified2: filename snort-unified.alert, limit 1
output log_null
}

u2spewfoo:

snort does not write an alarm event to unified2 ?
