[Bro] SSL Events not being triggered

[Shaanan Cohney]

I am having trouble getting any SSL events to trigger.


I've tested scripts against the snakeoil pcap from the wireshark sample pages, as well as my own data.


I've also tried scripts ranging from the one I actually plan to use, along with a few barebones ones.


When I use the -d flag and break on an connection I can see port 443 in the four tuple, but the SSL field remains uninitialized.


Here's a sample of something I tried


event bro_init(){
        #Analyzer::enable_analyzer(Analyzer::ANALYZER_SSL);
        #Analyzer::register_for_port(Analyzer::ANALYZER_SSL, 443/tcp);
}


event ssl_established(c: connection) &priority=3 {
      print c;
}

I've also tried my own compiled version of bro, and the apt package on the latest version of ubuntu.

I'm running bro as follows

bro -r a.pcap ./nameofscript.bro

Any help would be much appreciated!

Thanks,
snc
