X-BeenThere: freebsd-security@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Security issues [members-only posting] List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 03 Mar 2004 14:44:54 -0000 My setup 4.9 stable with IPFW. Machine acts as gateway for two machines. What are my options on monitoring activity on my external card? This morning I noticed my DSL modem activity light is blinking non-stop. Looking at /var/log/ don't see anything suspicious. I feel tempted to add "log" to all my ipfw pass rules, but wonder if there isn't a better way. I am mostly concerned there is either some kind of attack going on or somehow the machine was hacked and it's running something it's not supposed to.
