Linux 2.4 Packet Filtering HOWTO:
Introduction
Next Previous Contents
----------------------------------------------------------------------
1. Introduction
Welcome, gentle reader.
It is assumed you know what an IP address, a network address, a netmask,
routing and DNS are. If not, I recommend that you read the Network
Concepts HOWTO.
This HOWTO flips between a gentle introduction (which will leave you
feeling warm and fuzzy now, but unprotected in the Real World) and raw
full-disclosure (which would leave all but the hardiest souls confused,
paranoid and seeking heavy weaponry).
Your network is not secure. The problem of allowing rapid, convenient
communication while restricting its use to good, and not evil intents is
congruent to other intractable problems such as allowing free speech
while
disallowing a call of ``Fire!'' in a crowded theater. It will not be
solved in the space of this HOWTO.
So only you can decide where the compromise will be. I will try to
instruct you in the use of some of the tools available and some
vulnerabilities to be aware of, in the hope that you will use them for
good, and not evil purposes. Another equivalent problem.
