Smoothwall Express 3.1 RC4 发布，用来保护网络免受外来的攻击

Smoothwall是一系列的Internet安全产品，它被设计用来保护你的用户和网络免受外来的攻击。Smoothwall Express基于Linux操作系统。对安全系统而言Linux是一个理想的选择，它是可信赖的、安全的、具有高度可定制性并可免费获得其开放源码。Smoothwall包含一套经过加固的GNU/Linux操作系统，因此，无需再单个地安装其他系统。Smoothwall被设计为易于使用，并通过基于web的图形用户界面来进行配置。它并不要求用户具有Linux方面的知识就能安装和使用。

Neal Murphy has announced the availability of the fourth release candidate for Smoothwall Express 3.1, a specialist distribution for firewalls and routers: " The Smoothwall community is pleased to announce the fourth release candidate for our long awaited Smoothwall Express 3.1 firewall. RC4 corrects a few problems found in the third release candidate, settles on i586 and x86_64 as the system architectures that will cause the fewest problems when upgrading from 3.0, has a much re-worked QoS feature, and has Marco's URL Filter mod fully integrated. We expect RC4 to be the last release candidate before we release Smoothwall Express 3.1. The vast majority of the work was done 'under the hood'. Here are just a few of the software upgrades: Linux kernel 3.4, glibc 2.18, GCC 4.7.2, Perl 5.14.4, Squid 3.3.5, httpd 2.2.24, iptables 1.4.14 and Openswan 2.6.39."
