you can't blame the dshield install for providing you with the denylog entries.
that is what my messages log always resembles, until the internet link goes down.
if you haven't had these before, welcome to the world of portscanning.
my dshield install sends me an email saying
Modification of a read-only value attempted at /home/dshield/iptables/iptables.pl line 199, <CONFIGFILE> line 166.
and i don't understand what isn't right with the install.
any takers?
