# The log_in_vain MIB will provide you with logging of attempted # connections to your box on any port which does not have a service # running on it. For example, if you do not have DNS server on your # computer and someone would try to access your computer through DNS # port 53, you would see a message such as: Connection attempt to # UDP yourIP:53 from otherIP:X (where X is some high port #) displayed # on the root console screen. This message also gets posted to # /var/log/messages & /var/log/security.log. # The following statements enable this function. # man tcp(4) and man udp(4) contain a little information on these MIBs net.inet.tcp.log_in_vain=1 net.inet.udp.log_in_vain=1 I believe this description is pirated from the old 4.7 LINT kernel source file. The implied meaning is access you computer, as in from the external interface. Thats how I read that.
