Yes, a "firewall" works with just a few netfilter commands, but it is not just that :) And the iptables man page... is hard to memorize just its the full content/modules/options. What about kernel sysctl for example ? there is a whole "net" subsystem of kernel variables (sysctl -a | grep net) the documentation for that is included with the kernel sources and sparse on the internet... What about logrotate and rsyslogd config ? What about the subnets arp changes monitoring ? etc etc... > I need recommendations for literature or other sources of reliable knowledge > that start off with answers to questions such as: 'What is a port?'
