Depending on the OS. You may need to aet the port you are monitoring into permiscuous mode. Some do not auto configure I am not sure how secure it will be, it depends on the firewall. You still have a Mac address that can be attack I am also causious Sent from my iPhone On May 12, 2010, at 11:20 PM, "mike () grounded net" <mike () grounded net> wrote:
The server I'm using wireshark on has two NICs. I put NIC0 on the LAN side which is how I remotely manage the server. I put NIC1 on a hub just before the firewall so that I can see all public traffic before it hits the firewall. On NIC1, I do not have any IP assigned which is on my lan but have 169.254.1.2 on it. From what I understand, the NIC goes into promiscuous mode when wireshark and other network monitoring software fires up to use that NIC. What I wondered about was, just now safe is it to have that NIC on the public side? Thanks. ___________________________________________________________________________
