Hi,

I could not see binpac warning in Bro 2.0.

I used to see the binpac warning generated by &check statement, showing in the stdout. But now, I could not see any thing and could not find any thing in the log.

Here is how I test it. In the “default” branch of “case” statement, I write

default → unknown: Debug\_Byte **&check(0)**;

My purpose is that if the network packet is not correct, then it come to the default case, then I hope that binpac can directly give me some warning instead of writing bro script to detect it.

However, I did not see any warning in Bro 2.0 when this branch is entered.

Best,

Hui
