New books

Ordered on Amazon today:

I’m not sure what to make of the fact that these books are nearly 20 years old… totally out of date, but all that is available? What’s up with that?

Netfilter and iptables

This evening I read the iptables man page and Linux iptables Pocket Reference from cover-to-cover; my notes are here: Netfilter.

I think at this point I am ready to use iptables in anger for the first time in a long time, and the first time ever on a router.

However, before I take that on, I’m going to have a quick diversion into the following books, and then sleep, and I will do my iptables programming when I wake up tomorrow.
