Hello,
can someone please explain:
one of my boxes gets portscanned often by some likely infected laptops.
While having set
net.inet.tcp.blackhole=1
there are still messages like
+Limiting closed port RST response from 348 to 200 packets/sec
appearing. Are these RSTs actually sent out or does this just pop up
for some other reason ?
This is on 8.4-stable btw.
thanks,
Tee
