Hi,

For the purpose of testing my scripts, sometimes i am interested in looking at results only from a particular protocol. However, everything is enabled by default. So i have HTTP, SMTP, FTP… analysis going on when i am only interested in, say, DNS. I redefined PacketFilter::all\_packets=F in bro\_init but to no avail. Then i made the same change in the actual script file instead of redefining all\_packets in my script, still the same behavior. Please correct me if i am doing it wrong 🙂

Regards,

try:

&nbsp;&nbsp;&nbsp;&nbsp;redef PacketFilter::all\_packets = F;  
&nbsp;&nbsp;&nbsp;&nbsp;redef capture\_filters = [["only-dns"] = "port 53"];
