Operating System

Netwerk server met een hoge load kunnen “uitgeput” raken. Op z’n minst kan dit ervoor zorgen dat de server minder snel reageert. Maar als er niks aan gedaan wordt kan het uiteindelijk tot een crash leiden.

[quote]In order to understand and prevent such situations‚ a knowledge of the internal operation of the operating system is required‚ especially how memory management works.

This paper‚ by Philipp Buhler and Henning Brauer‚ will provide an understanding of the memory management of OpenBSD‚ how to monitor the current status of the system‚ why crashes occur and how to prevent them.

Blerry stuurde ons de volgende link over een duidelijke howto om een router/dhcp server op te zetten.

[quote][b]Objective:[/b]

The objective of this Howto: is to provide a user with beginning UNIX skills a pattern to create a FreeBSD Gateway through a Roadrunner cable connection (this setup has also been tested with the cable service provided by Comcast) that provides a DHCP and NAT interface to an internal network. Also included in this Howto: are instructions to add a firewall framework with ipfw to the kernel and some simple firewall rules. A full treatment of firewalls is reserved for a future Howto: or can be left as a exercise for the user as well.
