Hi Snorters,

I just made a rule to detect yahoo traffic, the rule
works fine but when i try tocheck the results usiong
ACID, my machine reboots. This has happened
consistently for six times now.

Here is the rule:
alert tcp $HOME_NET any <> $EXTERNAL_NET 5050
(msg:"CHAT Yahoo message"; flow:established;
content:"YMSG"; classtype:policy-violation; sid:540;

Any clues? Any suggestions? Is this rule right? Any
