Hello: Just need some clarification on Bro's configuration files. 1. In node.cfg, what if I have two interfaces on a server that I'll like to monitor, can I add the second interface, like "interface=eth0,eth1"? 2. Regarding the networks.cfg file, it says it's a "List of local networks", while the docs says it's list of "networks that Bro will consider local to the monitored environment". By "local", does that mean \_any\_ IP address network associated with the server, including that that a private interface belongs to, and the loopback interface? Thanks, ---
