oO I didn't know teamspeak used ssl....ok that explains a lot....

Thank you!

I'm wondering why they created a rule set for tcp if the standard is in ssl....

But like I said.. facebook is over ssl by default.. so you wont see this. only the initial request.

Josh,

Looks like this rule is just out of date. The post URL I see for this is 
`/ajax/mercury/send_messages.php<https://www.facebook.com/ajax/mercury/send_messages.php>` try that.

This rule is the one that was downloaded from snort.org<http://snort.org>....I don't have any custom rule sets.

I'm able to go to facebook chat and chat up a storm with someone I know and I don't even get an alert on it.

What does your rule look like. Also, isn't that ssl traffic? Are you looking for connections to a certain domain?

Anyway, lets see the rule and in sure we can get this going.

I'm having issues where I can't get the emerging threat rules to fire on instant messaging or logging into teamspeak

course of action to fix the issue?
