Securing 802.11 with OpenBSD.

How can we make sure that our WLAN traffic is useless for all unauthorized listeners? From the OSI layer 3 point of view, 802.11 is not different than any other LAN technique (ethernet, token ring..). This makes it possible to use standard solutions for securing IP traffic.
This document describes an implementation of 802.11 wireless LAN access point and VPN gateway using the OpenBSD operating system and how to secure the WLAN traffic with IPsec. We are going to utilize many of the hot Internet buzzwords

Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....

Multi-Boot Disk for Machines With AMD Opteron Processors

This article presents step-by-step procedures for loading the Solaris 10 OS on x86 platforms, and one or two 64-bit Linux operating systems, on machines based on 64-bit AMD Opteron processors. Installations were done on generic Opteron-based workstations and confirmed on a Sun Fire V20z server and Sun Java Workstation W1100z and W2100z workstations.
