[ILUG] Firewall type setting

[Brian Scanlan]

Is there a Linux equiv. to the FreeBSD kernel setting
sysctl -w net.inet.tcp.log_in_vain=1 ?

This logs all failed IP connections to your box, like
Jun 12 19:36:03 ugh /kernel: Connection attempt to UDP yourIP:23 from
otherIP:X 
if you don't have a telnet server running / other server on port 23.

Would this be a firewall thing?

Brian.

question of when the present century ends, as it is one of the most absurd that
can engage the public attention, and we are astonished to find it has been the
subject of so much dispute, since it appears plain. The present century will
not terminate till January 1, 1801, unless it can be made out that 99 are 100.
It is a silly, childish discussion, and only exposes the want of brains of
those who maintain a contrary opinion to that we have stated"
