[Zeek] Creating a module and accessing an event in another script

Hi All,

I cannot figure out why the Notice doesn’t behave as expected on live traffic. I am now trying to make it work with SSH (log_ssh) event as previous attempt on ssh_auth_result lead me nowhere. If I raise the NOTICE function  just after the log_ssh event from a script it sends me email on live traffic. However if I use the NOTICE function inside IF, ELSE IF, ELSE conditionals for auth_success boolean then it does not send me emails. Anyone see what I am doing wrong? I couldn’t figure it out from Notice documentation.

Please find attached the scripts for reference.

Kind regards,
Merril.

There are no released versions of zeek so I don't know when you built it.  Using bro_init is backwards compatible and is probably better for now.
