EnGarde Community Installation Review: A Server Testing Guide

A site for reviews and Linux, Piotr over at Polishlinux.org took a chance to review EnGarde Community for servers.

The site itself is a great resource for understanding how to compare, assess and choose the best distribution for you. SO make sure to check out their Distro chooser, a great little quiz that takes your preferences and recommends the best distro based on your answers. A nice resource as well. Check it out!.

Step-By-Step Guide To Building A Firewall With Netfilter

Every self-respecting Linux guru should be familiar with firewalls and how to install and configure them. With this in mind, Linux gurus also should be curious about how firewalls function and how to build a firewall of his or her own. . . .. Every self-respecting Linux guru should be familiar with firewalls and how to install and configure them. With this in mind, Linux gurus also should be curious about how firewalls function and how to build a firewall of his or her own. Explaining exactly these two things is the goal of this article. Here, we attempt to write a firewall in less than 60 lines of C code. As impossible as this may sound, it actually is quite simple to do using the power of Linux kernel modules and Netfilter. Netfilter is a packet filtering subsystem in the Linux kernel stack and has been there since kernel 2.4.x. Netfilter's core consists of five hook functions declared in linux/netfilter_ipv4.h. Although these functions are for IPv4, they aren't much different from those used in the IPv6 counterpart. The hooks are used to analyze packets in various locations on the network stack. The link for this article located at Linux Journal is no longer available. . Learn how to build a personal firewall in Linux using Netfilter with this sample C code that blocks incoming connections on a specified port.

This is the second in a series of articles about how to install and configure the Cyrus IMAP mail server, Postfix SMTP, and Procmail for server-side mail filtering. Last week, we covered the installation and basic configuration for Cyrus IMAP. Assuming you have Cyrus configured properly, there's one more thing you may need to do to get the IMAP server running. You need to start the authenticating agent pwcheck and restart the inetd Internet super-server. This should be as easy as the following commands, or something like them (depending on your distribution): The link for this article located at LinuxWorld is no longer available. .

Configuring Amanda Backup Utility for Multi-Platform Solutions

Amanda is the Advanced Maryland Automatic Network Disk Archiver, developed at the University of Maryland in the 1990s. While it is now maintained at SourceForge and support is provided only through mailing lists and a FAQ-O-MATIC, it is still a highly useful, stable network backup utility with a wide range of features. Amanda is tailored for networks that have a central server with a high-capacity tape drive and multiple backup clients. Although Amanda was built for UNIX systems, it has been extended to provide backup services to Windows clients (via Samba, although a separate project is underway to develop a native Windows client) to allow deployment in heterogeneous environments. In this article, I will review the installation and configuration process for Amanda and show how to tailor it to some of the potential environments it may be used in. The environment for this implementation consists of a Pentium II 350-MHz system running Slackware 8.0 and an Exabyte 8505 tape drive as the server, and clients including OpenBSD 2.8 and Red Hat Linux 7.1.
