Fedora 10 In Retrospect

The reason I write this review about fedora 10 is from few days the next new version of fedora (11) will be available and before all of us get in to the hype of fedora 11 I would like to talk about some nice features in fedora 10 which I liked and Used lot since it's release.


Plymouth graphical boot up system is one. It presents this attractive boot up screen and more importantly a faster boot up. It'll take 20 sec. or less to boot in to the system and Plymouth's major drawback is it doesn't support all graphics cards that is available. especially on low end cards.


It requires enabling kernel mode setting drives which is still in development and buggy. and also it hides boot messages so we have to disable it first if we want to take a look at them.


also the Gstreamer codec installation helper has been replaced with package-kit in fedora 10. if the user wants to play some media file by totem,if the necessary codecs haven't been configured,Package-kit can quickly search through the configured repositories for that particular codec and download. Its relatively great ease than manually doing the process.


Also fedora 10 came with improved web cam support and supports much larger number if web cams available. also fedora 10 offers infra-red remote control support. it has a graphical front-end for configuring LIRC devices.


you can use infra-red controllers very easily with totem and rhythembox just by plugging the device and selecting auto-detect in Infrared remote control preferences.


Bluetooth support stack has been upgraded also. (bluez) It has this new and easier to use wizard to configure Bluetooth devices. Bluetooth kernel driver also changed to 'btusb' greatly reducing power consumption compared to 'hci_usb'


Empathy instant messenger is also released with fedora 10 which supports multiple protocols to chat and XMPP fore voice and video.


Empathy used the telepathy framework that has a number of additional plugins.


Gnome display manager (gdm) was updated as well.


This release of Fedora came with an additional desktop


environment named LXDE. LXDE is a new project that provides a


lightweight, fast desktop environment designed to be usable and


slim enough to keep resource usage low.


And fedora 10 also supports a large number of languages greatly improving localization with it.fedora 10 also included a new on screen keyboard for indian languages.


Fedora 10 includes a number of applications and libraries that are


of interest to amateur radio operators and electronic hobbyists.


Many of these applications are included in the Fedora Electronic


Lab spin. Fedora also includes a number of VLSI and IC design


tools.


another new feature or application i like in fedora 10 is the Firstaidkit. it is a fully automated


recovery application that makes subsystem recovery easier for


technical and non-technical users.


Firstaidkit is designed to


automatically fix problems while focusing on maintaining user data


integrity. Its been available in rescue mode, on the the live CD.


Fedora 10 also supports ext4 filesystem and fedora 11 will be the first distribution that default file system is ext4.


Python NSS bindings also supported in fedora 10


Python bindings for NSS/NSPR allow Python programs to utilize


the NSS cryptographic libraries for SSL/TLS and PKI certificate


management. The python-nss package provides


a Python binding to the NSS and NSPR support libraries.


Network Security Services (NSS) is a set of libraries supporting


security-enabled client and server applications. Applications


built with NSS can support SSL v2 and v3, TLS, PKCS #5, PKCS #7,


PKCS #11, PKCS #12, S/MIME, X.509 v3 certificates and other


security standards. NSS has received FIPS 140 validation from


NIST.


also fedora 10 included best breed free software java implementation

obtained through active adoption of innovative


technology integrations produced by Fedora and others within


upstream projects.


In Fedora 10 gcjwebplugin has been


replaced by IcedTeaPlugin, which runs


untrusted applets safely in a Web browser and works on any


architecture. You can see which Applet Plugin is installed by


typing about:plugins in Firefox.


The new plugin adds support for the JavaScript bridge


(LiveConnect) that was missing from earlier versions.


Through the IcedTea project, OpenJDK has been integrated with


several new technologies that are also part of Fedora 10. Such as Visual VM intergration through the NetBeans Framework,Pulse audio intergration for javax.sound, Intergration of mozilla-rhino java script. Also in Fedora 10 Java cryptography


(javax.crypto) is fully supported without any


(regional) restrictions. Fedora 10 includes many packages derived from the JPackage


Project. This release of Fedora included Fedora Eclipse, based on the


Eclipse SDK version 3.4. also Fedora 10 included plugins for C/C++


(eclipse-cdt), RPM specfile editing


(eclipse-rpm-editor), PHP


(eclipse-phpeclipse), Subversion


(eclipse-subclipse), SELinux


(eclipse-slide) and


(eclipse-setools), regular expression testing


(eclipse-quickrex), Fortran


(eclipse-photran), Bugzilla integration


(eclipse-mylyn), Git


(eclipse-egit), Perl


(eclipse-epic), Checkstyle


(eclipse-checkstyle), and Python


(eclipse-pydev).


Fedora 10 also included the Babel language packs, which


provide translations for Eclipse and Eclipse plugins in a


number of languages.

Fedora 10 introduces better support for Haskell. With a new


set of packaging guidelines and tools, it is incredibly easy to


support any Haskell program using the Glasgow Haskell Compiler.


Package creation and deployment, leveraging Fedora's quality tools


plus a few new friends has never been easier.

Different roles are been available for SELinux to allow finer-grained


access control. The new sectool provides users with a


tool to check their systems for security issues. Included


libraries allow for the customization of system tests.


Virtualization in Fedora 10 includes major changes, and new


features, that continue to support KVM, Xen, and many other virtual


machine platforms.


This is a very short review of features in fedora 10 and it included very large number of improvements in various parts throughout the system.


so we can very much look foreward for the final release of fedora 11 hoping that it also will be a great OS as fedora 10 been for me for Past Six or so months.

Linux Prospects, Post-Windows 7

With the release of Microsoft's Windows 7 operating system slated for tomorrow, several Linux releases and announcements are arriving. Paula Rooney at ZDNet suggests that the Linux flurry may represent wave-making in reaction to the release of the much discussed new version of Windows. Does Windows 7 threaten to stifle Linux, and what are the prospects for Linux as Windows 7 rolls out?



More on Open Core

Many of the responses to my previous blog post "Open Core or Open Snore?" were in agreement, and some were not. As is often the case, the more interesting ones expressed disagreement. Some took issue with my post by pointing out open core companies that might be termed success stories: SugarCRM, Alfresco, Mindtouch. But then, I never wrote that open core cannot be successful, but rather that any success will be limited by nature of the model. Open core effectively places a cap on community development turning open source efforts into a viral marketing play, when it can be so much more.

One critique that did resonate was how much open source dev models actually impacted the bottom line. A company's success is impacted by a myriad of factors, including open source strategy and tactics.Seeing as how some companies will succeed with practically no open source development at all, it's only natural to concede that an open core approach will succed in some markets. However, if I were creating an open source community strategy in a crowded, competitive market, I sure wouldn't want to place an artificial handicap on my community development practices. I'll use 2 case studies to illustrate my point: Red Hat / Fedora and CollabNet / Subversion

SELinux Denial when Connecting to Internet From HSDPA modem in Fedora 10

Does anybody gets this SELinux Denial alert when connecting to Internet from HSDPA modem? (Huawei e160)


Summary:


SELinux is preventing NetworkManager (NetworkManager_t) "getattr" to /dev/ppp

(ppp_device_t).


Detailed Description:


SELinux denied access requested by NetworkManager. It is not expected that this

access is required by NetworkManager and this access may signal an intrusion

attempt. It is also possible that the specific version or configuration of the

application is causing it to require additional access.


Allowing Access:


Sometimes labeling problems can cause SELinux denials. You could try to restore

the default system file context for /dev/ppp,


restorecon -v '/dev/ppp'


If this does not work, there is currently no automatic way to allow this access.

Instead, you can generate a local policy module to allow this access - see FAQ

(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable

SELinux protection altogether. Disabling SELinux protection is not recommended.

Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)

against this package.

I use fedora 10 and my modem is Huawei e160

any suggestions or pointers to fix this thing?

Sometimes this cause to automatic disconnection and very annoying. I have got 181 errors of this sort. (Each time i Connect)

Do you think this is a bug. SELinux suggest to disable its protection to fix this but i think its not a good idea.


Prevent processes from dying when ssh shell dies

I am running Fedora Core 6 and my ssh terminal dies when it is inactive for a while. My issue is that I have several processes that need to run but they do not require any user input, and if the shell dies, the processes are killed too. I have tried suspending them, but that simply stops the processes. I have also tried running them in the background. What suggestions do you have?

IP Addresses of LAN devices

Hello. I am trying to find out the IP addresses on a given network for all machines connected on the LAN. How do I determine what IP addresses are part of the LAN? I am using Fedora Core 6

Iptables Firewall rules on Fedora?

I want to redirect all traffic coming to a server to another machine behind the firewall. The traffic is coming to a particular IP address (e.g. http://mybox.mydomain.com). I want to redirect all traffic coming to http://mybox to another machine (say, 192.168.1.50). Can I do this using iptables?

Root user not working

I am using Fedora core 8 and my problem is when I login as root, it loads improperly and system hangs. I dont have any such problems in normal user login nor using "su" in normal user login.

Even though I dont need root login much of the times, I require it at times for administration purpose. Suggestions?
