我曾经写过两篇日志,都是关于SELinux的安全设置问题,请参考:

我们到底该不该使用SELinux

关于SELINUX的权限问题

前两天,一同事去现场给客户部署系统,装好RHEL5.6之后,发现ftp和http都连不上,但是服务器的启动和服务状态都正常,ftp的返回结果是

500 OOPS: cannot change directory:/home/userDir

我再让他查看下权限、登陆的用户等,这些都没有问题,然后我问他,SELinux的状态是什么样的?他说是打开的,我就知道是这个问题了,在这些版本之后,默认SELinux都对网络操作本地文件系统做了很严格的控制,我觉得有必要在说一说这些东西。

首先是两个命令,getsebool和setsebool,从名字上面就可以知道,这是设置SELinux相关配置的开关(布尔值),那就说明各项开关的作用就行了。 (更多…)

很久没有关注Fedora了,早上一看,好家伙,现在都到 F15 Beta了,赶紧看看有啥更新,同时在想,我的Fedora Core 6也该换换了。。。

 

== Features ==

Desktop enthusiasts and end users of all sorts can look forward to:
    * Gnome Shell and the Gnome 3 desktop. Gnome 3 is the next major version of the Gnome desktop. After many years of a largely unchanged Gnome 2.x experience, GNOME 3 brings a fresh look and feel with GNOME Shell.
    * LibreOffice Productivity Suite. LibreOffice is a fork of OpenOffice, with the support of the OpenOffice.org community. All of the applications you know and love are still there, including apps for spreadsheets, document creation, and presentations.
    * Desktop environments a-plenty. The Xfce and LXDE spins have been updated, and the Fedora Spins SIG has other offerings tailored to a wide variety of user needs. 

Sysadmins will love features such as:
    * Appliance building. BoxGrinder creates appliances (virtual  machines) from simple plain text appliance definition files  for various virtual platforms, and is great for building appliances for use in a Cloud environment.
    * Dynamic Firewall. The dynamic firewall mode aims to make it  possible to change firewall settings without the need to restart  the firewall and to make persistent connections possible. 

Coders have lots of new development tools to try out, including:
    * Updates to popular languages. Python 3.2, Rails 3.0.3, and  OCaml 3.12 are all included in Fedora 15.
    * Project tooling. Maven 3 is a Java project management, project  comprehension, and build system tool.
    * Compiling and debugging. GDB gets an update to 7.3, and GCC 4.6 is included. (Fedora 15 has also been rebuilt using GCC 4.6!)

Fedora 13 final 版将推迟到5月25号发布

又跳票了啊,来自Fedora List的pipermail显示,原计划18号发布的Fedora 13 final 版将推迟一个星期到5月25号发布!

The F13 final readiness meeting, also known as the “go/no-go” meeting,was held this evening.  As the meeting notes indicate, there are bugs
remaining on the blocker list:

http://lists.fedoraproject.org/pipermail/test/2010-May/090880.html

According to the release criteria[1], the decision was made to slip the release of Fedora 13 by one week, to Tuesday 2010-05-25.

During composition of any further release candidates, the Fedora Release Engineering and Quality Assurance teams plan to be
conservative in accepting fixes for the release, and will limit these to blocker items and critical fixes.

The Fedora 13 release schedule[2] has been updated to reflect the new release date.  We regret any inconvenience to the community.  Thank you for your patience as we try to ensure the best possible Fedora release.

Fedora 14开发代号、发布进程公布:

Fedora 14的开发代号有六个候选者,经过社区投票后“Laughlin” 成为最后的赢家,一共获得了610 票,也延续了Fedora近年来以物理学家作为代号的传统。此前被认为可能性最大的Fytnargin反 而相当冷清,只有403票,其他还有Laramie 594票、Ventnor 570票、Mitikas 482票、Hoppin 459票。

Laughlin来自著名的理论物理学家Robert B. Laughlin,1950年生于美国加里佛尼亚 州,1998年荣膺诺贝尔物理奖,主要贡献是解释了分数量子霍尔效应,还提出了“整体大于部分之和”的概念,Fedora也正是取自这个寓意,代表它不仅 仅是开源软件的简单组合。
新系统将包括最新的Linux技术,包括尚未发布的Linux Kernel 2.6.34、X.Org Server 1.9、GNOME 3.0、GCC 4.5等等。

Fedora 14 Laughlin的具体发布日程为:

2010年8月17日:Alpha预览版
2010年9月21日:Beta测试版
2010年10月14日:RC候选版
2010年10月26日:最终正式版
