Hi, If I am not mistaken I think you are looking for ids. Your best bet would be something like snort ( snort.org ), as it recognizes multitude of attacks and probes. Logging incoming web server connections can be done via server log files, thats what they are for. Hope this helps. -- Alex Pavlovic Founder and CTO Corp-X Solutions http://www.corp-x.com -----Original Message----- From: owner-freebsd-security@FreeBSD.ORG [mailto:owner-freebsd-security@FreeBSD.ORG]On Behalf Of Maildrop Sent: Friday, October 11, 2002 10:18 PM To: freebsd-security@freebsd.org Subject: monitor ALL connections to ALL ports I currently have a DSL line and a FreeBSD firewall/gateway (dual homed). It has one internal IP address and 5 external IP address (one "real" ip and 4 alaises on same external nic). What I want to do is montior and record (to log) all incoming/outging connection (just source ip/dest ip/port). If someone connects to my web server it should log what ip accessed it, the time, which ip (web server runs on 2 external ip address) and the port. Also if someone does a port scan against the box I should be able to tell it is a port scan (since one ip address would be opening up a bunch of ports). Right now I don't care what data is being sent/received, just what connections are being made (and the details about those connections). Any suggestions?
